Expert Python engineer wanted
Do you have at least 5 years of programming experience, including at least a year with Python? (We mean open source and significant personal projects, too, not just formal jobs.) If so, you have probably written so much Python code in your life that, at times, you want to express your thoughts through list comprehensions. Thanks to your extensive experience, you can solve any problem that gets thrown at you, but that is not enough—you come up with multiple solutions for every issue, and you always know how to choose the most Pythonic one.

We’re not just looking for technical skills—we need someone who codes with passion and takes real pride in their work. If you thrive on solving complex problems, love diving into code, and are always looking for that next challenge, we want you on board. Your enthusiasm and drive must be as strong as your Python skills.
In our team, ownership is non-negotiable—it’s the backbone of our work style. We take responsibility for our code from the first line to deployment, ensuring it is rock-solid and efficient. If you’re the type who sees a project through, squashes bugs like a boss, and always thinks ahead, you’ll fit right in here.
And that is all a good sign—a sign that means you’re exactly the type of person we’re looking for! If you’d like to see what it’s like to work with Python natives who all bring their long-standing expertise to the table, please get in touch. Spoiler alert: it’s great!

We have good manners, though, so let us introduce ourselves first. Do you want to find out more about the company? We were hoping you’d ask. ;)

Get to know your future company
Reef Technologies is a fully remote Python backend software house. We’re a small, agile, senior-only team. All of our current members have more than five years of strong experience, so we don’t ever have anything urgent to fix. We only deliver stable solutions, as we have developed a system that has delivered more than a hundred challenging projects in the last three years. We’d like to improve it even further with you on the team.

Our main project right now is a trustless supercluster of performance-proofed GPU-enabled sandboxed docker container runners controlled by truly decentralized algorithms (not just PAXOS or RAFT).
