About the role

We’re looking for a Founding Engineer to help make foundational technology decisions and mentor a growing team. You'll build software that companies trust to shuffle packets around quickly and securely. This would be a great role for a seasoned engineer looking to join a fast-growing security startup.

Our Tech

We use a combination of Elixir/Phoenix and Rust. If you love solving complex, distributed systems problems and/or enjoy hacking on low-level networking code that interfaces closely with the operating system, this role is ideal for you!

If you're not an expert in any of the languages we use, that's ok! While a certain amount of Elixir and Rust proficiency is ideal for this role, we're happy to bring the right candidate up to speed. We value motivation to learn quickly and tackle challenging technical problems above all else.

What makes this role unique

  • Your work will be public — our codebase is open source.
  • Work closely with our users to ship features and fix bugs.
  • Be a founding engineer - You'll make and own core architecture decisions, shape company culture, and help set the bar for quality and execution.

Bonus points if you

  • Make contributions to open-source projects.
  • Love to write and share your expertise with others.
  • Previously worked at a startup or have an interest in startups.
  • Have experience building distributed systems on Erlang/OTP.

About the interview

We value the ability to learn quickly, take ownership, and ship product features over raw years of experience or company logos on your resume. Our goal is to make a well-informed decision based on your ability to do the work you’ll be expected to do at Firezone without subjecting you to a long drawn-out process. Our process involves:

  1. Introduction Call - A chance to connect and see if there is interest from both sides, share more about our vision and roadmap, and learn more about your experience.
  2. Take-home Coding Challenge - We're not fans of live, hours-long coding interviews since they don't resemble how most engineers get work done. Instead, we'll give you a 1-2 hour take-home challenge related to the role. You’ll be solving a problem similar to something you’d face in your day-to-day work.
  3. Followup Call - We’ll hop on a call to go through the completed take-home challenge and a few technical Q&A related to the role.
  4. Final call - If we have any additional questions we’ll schedule a short follow up call.
  5. Background and reference checks.
  6. Offer Decision

Why you should join Firezone

  • Remote-first work with the option to work locally out of our Mountain View office if you’re in the Bay Area. We attend conferences and hold fun off-sites, so you’ll still get the chance to meet everyone on the team if you work remotely.
  • Regular team off-sites (our last one was in Santa Rosa, California).
  • Flexible budget for your ideal workspace setup. Whether it’s a custom-built beefy Linux desktop or an Apple-powered mobile workstation — build your dream battlestation to get your work done! Use whatever gear suits you best.
  • Comprehensive medical/dental/vision plans.
  • Flexible work hours and paid vacation.
  • $100/month stipend to support open source.
