Self-driven and accountable: You’re comfortable managing your own projects and time without heavy oversight. When you take on a task, we can count on you to see it through with a sense of ownership. You’re a proactive problem solver who can break down complex problems, propose solutions, and drive them to completion. We trust our team members to be “managers of one” who take initiative and deliver results Great communication and empathy are a must. You enjoy working closely with others, be it in pair programming, brainstorming with designers, or reviewing a teammate’s code. You can explain technical concepts clearly, listen to alternate viewpoints, and work together to find the best solutions.

You’ll never be bored here. This Role Might Not Be for You We want to respect your time by being clear about what this role isn’t. You should skip this opportunity if: You prefer well defined structure. If you gravitate towards a clear hierarchy, well defined roles and swim lanes, you may find our self-managed style challenging. Distributed work isn’t your thing. If you find async communication, design documentation and being proactive without a manager nearby difficult, our setup won’t suit you. Feedback doesn't excite you. We’re obsessed with quality and believe in continuous improvement. That means we give feedback that’s sometimes nitpicky. If refining the work until it’s excellent feels over the top, you are likely going to find working here frustrating. Change makes you uncomfortable. We’re scaling and maturing. That means not everything is perfect yet. Priorities shift. Processes evolve. If ambiguity is uncomfortable, this may feel bumpy. However, If this sounds like fuel, we’d love to talk!
