About Us

DynamiCare Health is a digital therapeutics startup that helps people overcome addiction.

DynamiCare has won FDA Breakthrough Status and is already breaking into U.S. healthcare system reimbursement with partners that include the State of Rhode Island, Allegheny County of Pennsylvania, BCBS of Massachusetts, Horizon BCBSNJ, Spring Health, and Cityblock Health.

We understand that recovery isn’t one-size-fits-all, which is why our platform provides the flexibility and continuous support needed for sustainable behavior change. We’re transforming addiction care and helping more people reclaim their lives from substance use disorders. Through the Digital Recovery Platform, DynamiCare is bringing proven therapeutic approaches into the digital age, making recovery support available whenever and wherever our members need it most.

About the job

Working as a Full-Stack Engineer at DynamiCare, you’ll join a fully remote Agile team to design, build, and maintain secure, evidence-based applications. Since we’re a small business, you’ll have the opportunity to wear many different hats related to DevOps, Security, and other engineering-related fields.

As the primary developer at DynamiCare, you’ll have ownership over the codebase, making this a huge opportunity for impact. There will also be room for growth in terms of leadership as the team expands, with potential to shape practices, mentor future developers, and take on greater responsibility in technical decision-making.

We are currently striving to expand our user base and increase retention rates, with a Series A funding round on the horizon. We use a Ruby on Rails application, which powers multiple subdomains and includes a REST API that supports our member-facing React Native mobile app, as well as an Analytics application utilizing ActionView, React, and Stimulus.

We believe DynamiCare is a great place to work. You’ll collaborate in real time to make informed product decisions and play an active role in shaping the company’s direction every day. We value your time and mental well-being, and we offer flexibility in working hours and time off. While there may be times when you need to jump in to resolve a critical bug, we strive to stay calm, focus on the root cause, and improve our workflows rather than place blame.

Here are some examples of the work you might be doing at DynamiCare:

• Monitoring and responding to mobile and server package vulnerabilities, applying patches promptly, and evaluating whether they pose any risk to our users.
• Refactor Rails models to enhance feature development and data processing efficiency.
• Improve our appointment tracking features to include recurring appointments.
• Maintaining a probability engine used to schedule substance tests, ensuring functionality by writing a comprehensive suite of unit and integration tests.

• Creating and maintaining new background jobs to improve the scalability and performance of our application.
• Ensuring data security, privacy, and compliance with HIPAA.

About you

We’re seeking a candidate with a passion for technology and a motivation to make the world a better place.

Your primary responsibilities will include full-stack development, DevOps, and maintaining strong data security across our platform. You should have at least three years of experience with our core frameworks: Ruby on Rails and React Native. Experience deploying and managing applications using CircleCI, Aptible, and AWS is especially valuable.

Experience working within the confines of HIPAA and 42 CFR Part 2 is a strong plus, given the sensitive nature of our work. We’re also looking for someone familiar with Agile development, particularly Scrum and sprint-based workflows. Proficiency with collaboration and project management tools like Asana, Confluence, and Jira is important for staying aligned with the team.

Even though you’re experienced, we don’t expect you to hit the ground running on day one. We value thoughtful onboarding and provide you with the time and support needed to learn our systems and processes. Strong communication is essential here, whether you’re debugging code, collaborating with designers, or explaining technical concepts to non-technical teammates.

We also foster a collaborative environment where every voice is heard, and respectful dialogue and constructive feedback are encouraged. Our shared goal is to build a product that helps people recover from addiction, and we believe that happens best when everyone works together with openness and clarity.

A Computer Science degree or equivalent is not required for this position. If you have the chops and the skills needed to do the job well, that’s all that matters.

While you’ll report to our Director of IT & Engineering, we strongly believe in autonomy here at DynamiCare. It’s vital that you know how to manage your time, and we trust that you will as well. Investing the time and effort here will help advance your career and expose you to new and exciting challenges.

This position is remote and operates on Eastern Time. You’re free to work wherever you succeed the most: whether it be at home or in a coffee shop. We are hiring from anywhere in the United States.

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?
