Why should you join Secfix?

Secfix is an early-stage fully remote startup in the best sense of the word. We’re a fun, close-knit team on a mission to automate security and compliance for modern companies and become the European compliance automation leader. We rapidly grew from just three founders to 20 people in less than 2 years after founding.

Your work will significantly impact our tech product used by CTOs, engineering teams, COOs and the whole team will celebrate your wins.

In comparison to many startups we are growing the team at a healthy rate and there is a balance between fast growth and maintaining our runway as we scale. Most of our costs are already covered by revenue.

With new challenges (we're looking to 2x the team next year), you're assured of growth and progress. Our trajectory is fueled by top investors, including Octopus Ventures, Neosfer (Commerzbank), founders of Signavio and many more angels.

Who are we looking for?

We're building an environment at Secfix where ambitious, independent engineers can thrive. We want to grow with people who take pride on building and maintaining actual products, who are curious about how the features we ship are used daily to solve real challenges, and who'll use their in-depth engineering insights to push the envelope on what we can achieve together. We own products and outcomes, not Jira tickets.

Bring your commitment and drive to grow, and we’ll deliver an environment that keeps you happy, healthy, and empowered to do your best work with us.

Scope of this role: 90% backend troubleshooting, 10% new feature development.

Experience that you will ideally bring

• 1+ years of experience in Backend Engineering through first full-time job and internships.
• Solid foundation in object-oriented programming with Java.
• First professional production experience in Java Spring Boot, Hibernate, and SQL.
• Familiarity with 3rd-party APIs and interest in learning monitoring and troubleshooting.
• Willingness to take ownership of tasks, collaborate, and adapt to feedback.

You should apply if:

• You’re ambitious, independent and growth-oriented.
• You bring young talent to our team with at least 1 year of equivalent experience.
• You have strong engineering fundamentals, code efficiently, and you know what you're great at and what you're less great at.
• You thrive when you have autonomy, own as many of the details as possible, and project manage your own work.
• You’re comfortable collaborating and communicating in a remote environment, especially in writing and on video calls. You understand that working remotely doesn't mean working alone. Remember, it requires more pro-active communication than working in the office.

You should not apply if:

• You need a lot of processes to tell you what to do or you're comfortable only picking up highly detailed tickets from a JIRA board
• You only want to write code and don’t really care about the bigger picture and customers
• You don’t want to test, deploy, monitor and troubleshoot your own code
• You don’t want to lead your own projects, but rather be led by someone else
• You don't want to collaborate closely with other areas of the business or engage with users when needed

What happens when you join us?

• You’ll own complex backend issues: Work closely with the Tech Lead to take on challenging backend problems and resolve them autonomously.
• You’ll debug, troubleshoot, and fix bugs: Solve real customer-impacting issues in our production environment, ensuring a smooth experience for our users.
• You’ll strengthen your backend skills: Work with cutting-edge technologies like Java Spring Boot, Hibernate, and SQL, and develop a strong foundation in backend development.
• You’ll collaborate and grow: Work with a talented and supportive team to analyze root causes, design solutions, and improve our backend systems.
• You’ll contribute to new features: Occasionally work on feature development as the team and product expand.
• You’ll live by our values:
  • We are obsessed with our customers.
  • We build smart.
  • We create trust
  • We are hacky.
  • We take ownership.
  • We are leaders of remote

Applicants can expect the following:

1. An Introductory call with a member of our talent team ~ 15-20 minutes
2. Take home task (scope: max. 1-2h) and technical interview with Tech Lead
3. Virtual on-site with the team and co-founders on Gather.town (approx. 2 hours)
4. Offer stage

After sending us your application in, please keep an eye out for an email from Grigory (CTO) or Chiara (People Ops). We will respond and move as quickly as possible.

What We Offer

• Remote Work: 100% remote work with a virtual office in Gather.
• Competitive Salary: Industry-competitive local salaries. We pay local rates that are at or above the market. We share this philosophy with GitLab.
• Equity: Generous equity package – we’re all owners of Secfix and beneficiaries of our collective success.

About Buoy SoftwareOur mission is to deliver the best experience possible to as many donors of blood products (such as plasma) as possible, in as many communities as possible. We use our understanding of blood product donation and the industry’s regulations and pair them with our extensive consumer product experience to enrich the lives of our members and improve health outcomes for patients everywhere. In an industry that hasn’t seen innovation in more than two decades, Buoy’s software streamlines the donation process allowing our business to promote loyalty while improving efficiency in a donation center. In turn, the increase in blood product donations improves a supply level that is at an all time low, and allows for blood-product derived biotherapies to continue to evolve, improve, and save lives for those who face life-threatening conditions (i.e. immune deficiencies and blood disorders). Without an increase in blood product donations, we are facing a worldwide health crisis that ultimately results in rationing of care without the proper resources.

About GFX Labs

Based in Chicago, GFX Labs is a research and development company founded in 2021, dedicated to pushing the boundaries of decentralized finance (DeFi). The company designs and builds cutting-edge tools and platforms for financial services, on-chain data integration, and professional trading experiences. Beyond product development, GFX Labs plays a key role in DeFi governance, contributing to the evolution of major blockchain protocols. With a mission to innovate and democratize finance, the company collaborates with regulators and industry leaders to shape the decentralized financial ecosystem. Its team of experts is committed to delivering impactful solutions for the future of blockchain-based finance.

GFX Labs operates two distinct isions. Our primary ision focuses on Oku, our comprehensive DeFi application. We have partnered with the Uniswap DAO, the leading decentralized exchange, and recently announced a collaboration with Morpho to integrate borrowing and lending into Oku.

Our second ision is dedicated to research and development. This work spans various areas, including analyzing the economic safety of on-chain financial mechanisms, designing user experiences, and indexing data for integration into existing products. The GFX team possesses a wide range of skills and has a strong track record of delivering high-quality services to industry-leading organizations.

Why work at GFX?

• Any firm can pay a high salary and offer good incentives (as will we), but most can’t offer interesting, challenging, and rewarding work.
• We have something to prove. Our team is young and hungry. We like to move fast and make things. We know when to double down and when to cut our losses. We are going to make mistakes, and we are going to build a better product because of them. We don’t micromanage or have a huge team of product managers. We want self starters who take charge and solve problems.
• We don’t care if you went to school, what grades you got, or your age. Show us what you have built, what problems you have solved, and what skills you have.

About Us

Close is a bootstrapped, profitable, 100% remote, ~100 person team of thoughtful iniduals who prioritize taking ownership and making a meaningful impact. We’re eager to make a product our customers fall in love with over and over again.

We 💛 small scaling businesses. Since 2013, we’ve been building a CRM that focuses on better communication, without the hassle of manual data entry or a complex UI. We are out to supercharge sales productivity with the most modern, thoughtfully designed, all-in-one, communication-focused CRM.

Art+Logic is looking for Senior Python Web Developers to work with us on interesting custom software projects. We’ve been an all-remote company since day one—more than thirty years ago.

Our ideal developers thrive in the environment of variety and challenge that is inherent to custom software development, working with us in a long-term relationship over many projects for numerous clients.

The skills and needs for each project we tackle can vary widely; this goes beyond just the languages and technologies we use, and extends to the industries and problem domains we work in. We love working with developers who are excited to learn and take on new challenges. You can expect to grow in your strength and your versatility at Art+Logic and we want to help you do so.

We work completely remote. We expect you to be able to work with minimal supervision and comfortably with small teams of 3-8 people. You won’t have someone looking over your shoulder, so you'll need to be communicative and reliable, and hold yourself accountable.

We value work/life balance, and our projects keep meetings to a minimum to ensure everyone has the flexibility to work during the times that work best for them. We are looking for contract developers able to commit between 30 and 40 hours a week most weeks, and we never expect our developers to consistently work more than 40 hours in a given week.

Art+Logic is run by humans, who work and create using technology. Things can go wrong and we need to respond to the unexpected by being kind, considerate, fair, flexible, and calm. We treat our clients and peers as respectfully as we ourselves would like to be treated.

This position pays between $30-$40 USD/hour.

**Qualifications

• 5+ years of Python experience in a web development context.
• 5+ years of JavaScript front-end development.
• Deep knowledge of Python 3.
• Experience with Vue.js or React.
• Excellent verbal and written communication skills in English.
• Experience with Django and SQLAlchemy is a plus.
• Experience with AWS and AWS lambda is a plus.

**

We are looking for Contractors (1099) for long term open-ended relationships, which includes company to company positions. Work hours are flexible; requiring reasonable overlap with normal US working hours to support team communications, and not just nights and weekends. 

Our rates range from $30-$40 USD/hour. 

We are ONLY looking for people in the United States, Canada, Mexico, Central America, South America, and the Philippines.

It’s important to us in the hiring process that we allow developers to demonstrate their abilities by actually developing something, because a list of previous employers or educational background aren’t always indicators of what someone can do. All applicants are asked to submit a solution to a programming challenge that emulates a task we might assign on a project. 

We have an asynchronous Recruiting Process which means we are always looking for great programmers that we’re excited to work with, without an immediate, specific position or opening in mind. Successful completion of our challenge and process leads to us looking for an opportunity for us to begin working together. This also makes our Recruiting Process very flexible, though we are not usually a good fit for those needing immediate work.

MANUAL is a digital personal development and mental wellness platform designed to inspire young men to become the best versions of themselves. Today, male students are far less likely to be enrolled, retained, and graduate from higher education institutions, and this is especially true for young men of color. Their mental health outcomes are rapidly worsening, with young men dying by suicide and overdose at alarming rates.

MANUAL works with high schools, universities, and fraternities across the country – including the University of Mississippi, Morgan State University, and MSU-Denver – to solve this challenge, bringing high-quality men's success and mental health programming to tens of thousands of students. MANUAL has raised capital from Expanse Venture Partners, 12-48, the Inner Foundation, and angel investors from companies like Maven Clinic, McKinsey & Company, Eleanor Health, and more. MANUAL’s evidence-based approach has been proven to enroll young men who are not currently being reached by existing services, and users report significant levels of trust towards the service.

Are you passionate about crafting efficient and scalable applications? Do you want to use your skills to help thousands of young men around the country? If you're enthusiastic about full stack Typescript, and love the thrill of a startup, we’d love to talk to you!
