• Lead our SOC 2 compliance efforts, implementing security best practices

• Create robust APIs that power our AI-driven supply chain platform

• Optimize for performance, reliability, and cost across cloud providers

• Security-first mindset with understanding of compliance frameworks

• Self-driven approach with ability to own projects end-to-end

• Built AI/ML infrastructure or data pipelines at scale

• Experience with multi-cloud deployments and cost optimization

• Track record of improving developer velocity through tooling and automation

• Background in supply chain, logistics, or enterprise software

Why Join Us?

• You'll have direct impact — this isn't a cog-in-the-machine role

• Own the entire backend architecture and infrastructure decisions

• Work with a lean team where your decisions shape the product and culture

• Build fast, experiment often, and learn from real users

• High ownership with the flexibility to work where and when you're most productive

• Join early, grow with the company, and help define engineering excellence

To Apply

Tell us about a backend system you built that balanced rapid development with production reliability. We'd love to hear about a time you improved deployment speed, reduced cloud costs, or implemented security controls without slowing down the team.

We are hiring a contract-based Senior Elixir Engineer for the garden3d creative collective

About garden3d

We are worker-owned creative collective, innovating on everything from brands and IRL communities to IoT devices and cross-platform apps. We share profit, open source everything, spin out new businesses, and invest in exciting ideas through financial and/or in-kind contributions.

Our client roster includes Google, Stripe, Figma, Hinge, Black Socialists in America, ACLU, Pratt, Parsons, Mozilla, The Nobel Prize, MIT, Gnosis, Etsy & Gagosian. We’re the software team behind innovative products like The Light Phone & Mill, and we a global, decentralized community space collective called Index Space.

We think of our garden3d as a collective for creative people, prioritizing a happy, talented, and erse studio culture. We work on projects that bring value to our world, and we balance deep care for the work we do with a genuine curiosity about life outside of our jobs.

Who we’re looking for:

Right now, we’re looking for a Senior Elixir Engineer with expertise in web, backend and/or native app development, and interest in systems architecture and IoT.

In this role, you’ll work on a variety of client projects to find cost-effective, high-quality, pragmatic solutions to complex problems. You would work on full-stack apps across many industries, from e-commerce to connected hardware products. Responsibilities will include:

• Crafting technical architecture plans through interfacing with clients to understand product requirements
• Developing and optimizing technical solutions while keeping in mind performance, scalability, maintainability, and cost-effectiveness
• Participating in code reviews, providing constructive feedback to teammates and ensuring adherence to best practices
• Contributing to project success by keeping a close eye on team velocity, project scope, budget, and timeline
• Negotiating with clients to align project scope with budget and timeline, if needed

The person we’re looking for is happy, relaxed and easy to get along with. They’re flexible on anything except conceits that will lower their usually outstanding work quality. They work “smart”, by carefully managing their workflow and staggering features that have dependencies intelligently — they prefer deep work but are OK coming up to the surface now and then for top level / strategic conversations.

We believe people with backgrounds or interests in design, art, music, food or fashion tend to have a well rounded sense of design & quality — so a variety of hobbies or side projects is a big nice to have!

Must Have Competencies:

• Fluency in Elixir, and production experience maintaining Elixir Phoenix apps
• 8+ years general experience in backend (Ruby on Rails, Elixir Phoenix, Python Django, or Node Express) and/or native app development (React Native, Flutter, Android, AOSP, Kotlin/Java).
• Comfort with building performant and polished frontend applications (React, CSS, Accessibility, etc)
• Extensive experience with API Design and knowledge of REST and GraphQL, as well as authentication strategies with JWTs and OAuth 2.0.
• Fluency in SQL & database operations, and extensive experience with one of PostgreSQL, MongoDB, MySQL or SQLite.
• Fluency in HTTP, Caching, Status Codes, Security Standards and other Web protocols & patterns.
• Experience with AWS, GCP, or Azure and a core understanding of best practices such as IAM & credential management.
• Production experience with PaaS providers such as Heroku, Render, Cloud66, Vercel, Elastic Beanstalk, EC2, Docker, or Gigalixir.

Nice to Have Competencies:

We’re always pitching for new and exciting technology niches. Some of the areas below are relevant to us!

• Fluency in Elixir LiveView or experience with Rails Hotwire
• Experience working with LLMs, Vector Databases, and other generalist AI-enabled application patterns
• Product management experience, including defining product roadmaps and working closely with stakeholders.
• Hands-on experience with Zenhub, Trello, Jira or similar.
• Client-facing experience, working directly with customers to gather requirements and provide technical solutions.
• Engineering management experience, including leading teams, setting technical direction, and mentoring developers.
• Experience in Hardware, Firmware, or Internet of Things (IoT).
• Native IDEs (Xcode, Android Studio), Languages & Low Level experience (Swift, Rust, C & C++, Clang & LLVM), Electron, V8 & NAN.

Compensation

Our pay scale ranges from $85 p/hr to $130 p/hr pending seniority (& team leadership experience), and our projects are rarely less than 8 full-time weeks at 40 hours per week. Additionally, we pay discretionary bonuses for going over and above — like training & coaching others, winning new business, speaking at conferences, etc.

We prefer long standing relationships with highly accountable and communicative team members, so we encourage candidates to expect longer term engagements. A senior engineer working 40 — 45 full time weeks may take home $150k — $225k USD.

How we interview:

Our interview process starts with a call where you get to meet a few members of our team. From there we’ll ask appropriate candidates to take part in a technical exercise which helps illustrate skill level and comfort.

→ It’s also a great way to see what it’s like to work with us and help support folks who may not have the ‘right title’ but have the experience and technical know-how for the role.

‍ How we work:

We believe that there’s a better balance between the poles of freelancing & full time, and for that reason Sanctuary works differently to most shops:

• Transparency & Ownership: We release out Profit & Loss statements to the community each year, open source our best ideas, and talk business & money with everyone in the company. We’re proud to run our business with integrity, and for that reason we share everything with our team & community.
• **150% Carbon Negative:** Our studio offsets 150% of the carbon we use to do business each year, dated back to our founding in 2015. We turn down work that is not in-line with our morals, and we encourage our peers to do the same. We were certified climate neutral earlier this year.
• **Strong Morals:** Since our founding, we've turned down somewhere between $1mm - $2mm of work that didn't meet our moral standards. (Most of that was DTC brands that can't show a valid sustainability initiative).
• Async & Decentralized: We use tools optimized for calm, thoughtful communication, and opt for async whenever possible. We fight hard to maintain our focus time.
• Remote Friendly: Our company is fluent in remote work, making our workplace more decentralized, and democratized in the process.
• Ideas & Products: In our spare studio time, we work to build our own open source or internal products to ersify & bolster our income. We create amazing technology products for our clients, so why not for the studio?

We are flexible! For the right candidate we ask: What do you need to do your best work?

Overview:

Ready to be pushed beyond what you think you’re capable of?

To achieve our mission, we’re seeking a very specific candidate. We want someone who is passionate about our mission and who believes in the power of crypto and blockchain technology to update the financial system.

While many roles at Coinbase are remote-first, we are not remote-only. In-person participation is required throughout the year. Team and company-wide offsites are held multiple times annually to foster collaboration, connection, and alignment. Attendance is expected and fully supported.

The Coinbase Developer Platform APIs are the easiest way for developers to get started with building crypto applications. Conceived by Coinbase CEO Brian Armstrong, these APIs enable those with no prior knowledge of crypto to begin sending and receiving crypto in as little as 30 seconds. A top priority of the Coinbase Developer Platform (CDP), the CDP APIs encapsulate some of the most cutting-edge technologies in crypto by externalizing Coinbase’s internal services, built over more than a decade of experience. The CDP APIs combine custodial and non-custodial wallets into one clean abstraction, making interactions with the blockchain simple and painless.

The CDP API team owns both server-side APIs and client-side libraries across different languages. The team seeks a full-stack engineer who is passionate about all aspects of excellent developer experiences: authoring clear and informative documentation, building compelling sample applications, interacting directly with customers to incorporate feedback, architecting delightfully simple SDKs, etc. The engineer must be comfortable operating in both frontend and backend codebases, fluent across a variety of programming languages, and demonstrate both high code velocity and quality simultaneously. The CDP API team consists of some of the most prolific and tenured software engineers at Coinbase, and is excited to ship a game-changing set of APIs and SDKs at breakneck speed.

What you’ll be doing (ie. job duties):

⦁    Design, develop, and maintain scalable, secure, and high-performance backend systems for the CDP APIs using Go and Javascript

What we look for in you (ie. job requirements):

⦁    5+ years of experience in both backend and frontend software development

We’re the software team behind innovative products like The Light Phone & Mill, and we a global, decentralized community space collective called Index Space.

We think of our garden3d as collective for creative people, prioritizing a happy, talented, and erse studio culture. We work on projects that bring value to our world, and we balance deep care for the work we do with a genuine curiosity about life outside of our jobs.

🔮 Who we’re looking for:

Right now, we’re looking for a Senior Elixir Engineer with expertise in web, backend and/or native app development, and interest in systems architecture and IoT.

In this role, you’ll work on a variety of client projects to find cost-effective, high-quality, pragmatic solutions to complex problems. You would work on full-stack apps across many industries, from e-commerce to connected hardware products. Responsibilities will include:

• Crafting technical architecture plans through interfacing with clients to understand product requirements
• Developing and optimizing technical solutions while keeping in mind performance, scalability, maintainability, and cost-effectiveness
• Participating in code reviews, providing constructive feedback to teammates and ensuring adherence to best practices
• Contributing to project success by keeping a close eye on team velocity, project scope, budget, and timeline
• Negotiating with clients to align project scope with budget and timeline, if needed

The person we’re looking for is happy, relaxed and easy to get along with. They’re flexible on anything except conceits that will lower their usually outstanding work quality. They work “smart”, by carefully managing their workflow and staggering features that have dependencies intelligently — they prefer deep work but are OK coming up to the surface now and then for top level / strategic conversations.

We believe people with backgrounds or interests in design, art, music, food or fashion tend to have a well rounded sense of design & quality — so a variety of hobbies or side projects is a big nice to have!

💸 Compensation

Our pay scale ranges from $85 p/hr to $130 p/hr pending seniority (& team leadership experience), and our projects are rarely less than 8 full time weeks at 40 hours per week. Additionally, we pay discretionary bonuses for going over and above — like training & coaching others, winning new business, speaking at conferences, etc.

We prefer long standing relationships with highly accountable and communicative team members, so we encourage candidates to expect longer term engagements. A senior engineer working 40 — 45 full time weeks may take home $150k — $225k USD.

🔑 Must Have Competencies:

• Fluency in Elixir, and production experience maintaining Elixir Phoenix apps
• 8+ years general experience in backend (Ruby on Rails, Elixir Phoenix, Python Django, or Node Express) and/or native app development (React Native, Flutter, Android, AOSP, Kotlin/Java).
• Comfort with building performant and polished frontend applications (React, CSS, Accessibility, etc)
• Extensive experience with API Design and knowledge of REST and GraphQL, as well as authentication strategies with JWTs and OAuth 2.0.
• Fluency in SQL & database operations, and extensive experience with one of PostgreSQL, MongoDB, MySQL or SQLite.
• Fluency in HTTP, Caching, Status Codes, Security Standards and other Web protocols & patterns.
• Experience with AWS, GCP, or Azure and a core understanding of best practices such as IAM & credential management.
• Production experience with PaaS providers such as Heroku, Render, Cloud66, Vercel, Elastic Beanstalk, EC2, Docker, or Gigalixir.

💪 Nice to Have Competencies:

We’re always pitching for new and exciting technology niches. Some of the areas below are relevant to us!

• Fluency in Elixir LiveView or experience with Rails Hotwire
• Experience working with LLMs, Vector Databases, and other generalist AI-enabled application patterns
• Product management experience, including defining product roadmaps and working closely with stakeholders.
• Hands-on experience with Zenhub, Trello, Jira or similar.
• Client-facing experience, working directly with customers to gather requirements and provide technical solutions.

• Experience in Hardware, Firmware, or Internet of Things (IoT).
• Native IDEs (Xcode, Android Studio), Languages & Low Level experience (Swift, Rust, C & C++, Clang & LLVM), Electron, V8 & NAN.

🎤 How we interview:

Our interview process starts with a call where you get to meet a few members of our team. From there we’ll ask appropriate candidates to take part in a technical exercise which helps illustrate skill level and comfort.

→ It’s also a great way to see what it’s like to work with us and help support folks who may not have the ‘right title’ but have the experience and technical know-how for the role.

👩‍🏭 How we work:

We believe that there’s a better balance between the poles of freelancing & full time, and for that reason Sanctuary works differently to most shops:

• Transparency & Ownership: We release out Profit & Loss statements to the community each year, open source our best ideas, and talk business & money with everyone in the company. We’re proud to run our business with integrity, and for that reason we share everything with our team & community.
• **150% Carbon Negative:** Our studio offsets 150% of the carbon we use to do business each year, dated back to our founding in 2015. We turn down work that is not in-line with our morals, and we encourage our peers to do the same. We were certified climate neutral earlier this year.
• **Strong Morals:** Since our founding, we've turned down somewhere between $1mm - $2mm of work that didn't meet our moral standards. (Most of that was DTC brands that can't show a valid sustainability initiative).
• Async & Decentralized: We use tools optimized for calm, thoughtful communication, and opt for async whenever possible. We fight hard to maintain our focus time.
• Remote Friendly: Our company is fluent in remote work, making our workplace more decentralized, and democratized in the process.
• Ideas & Products: In our spare studio time, we work to build our own open source or internal products to ersify & bolster our income. We create amazing technology products for our clients, so why not for the studio?

Who We Are:

Ethena Labs is at the forefront of the next wave of DeFi, dedicated to building products for modern finance. Ethena is a synthetic dollar protocol built on Ethereum that provides a crypto-native solution for money, USDe, alongside a globally accessible dollar savings asset, sUSDe.

Our core mission is to provide truly crypto-native financial solutions that are globally accessible and bridge the gap between TradFi and the digital asset economy. We believe in transparency, efficiency, and empowering both iniduals and institutions with greater control over their assets.

What we are Doing:

Ethena Labs is actively building and deploying a suite of groundbreaking products designed to address key challenges and unlock new opportunities within the digital finance landscape.

Our flagship product, USDe, is a synthetic dollar backed by digital assets, and takes the novel approach of using a delta-neutral hedging strategy to maintain its peg. This provides a truly scalable and censorship-resistant digital dollar.

Building upon USDe, we offer sUSDe. sUSDe provides crypto-native rewards generated from funding rates in derivatives markets, offering an alternative to existing products tethered to the traditional financial system.

Furthermore, we are actively developing solutions to facilitate institutional adoption of digital assets. In partnership with Securitize and Blackrocks BUIDL fund, USDtb provides a more traditional, asset-backed stablecoin option, leveraging established financial infrastructure to appeal to institutional clients. Expanding on this, iUSDe is designed specifically for traditional financial institutions, incorporating necessary compliance features to enable them to access the crypto-native rewards our protocol generates, in an institutional-friendly manner.

Finally, our most ambitious undertaking to date is Converge, our joint blockchain initiative with Securitize. This hybrid blockchain is designed to be the nexus where DeFi meets the needs of CeFi and TradFi. Converge aims to be a primary issuance layer for tokenised assets, integrating seamlessly with existing DeFi protocols to provide institutions with an environment to participate in the decentralised economy.

Through these offerings, Ethena Labs is not just creating new financial products; we are building the foundational infrastructure for a more open, efficient, and interconnected global financial system.
