p>Role Mission:
We’re building a team of highly‑skilled engineers who want one thing above all else: to write excellent code, every day, and continuously level up technically. You’ll be the kind of person who thrives on solving hard technical problems, learning from brilliant peers, and getting deep into the codebase day in, day out. This isn’t solo hacker mode. You’ll be part of a high‑performing team and expected to navigate real‑world, fast‑moving client projects.

That means collaborating thoughtfully, communicating clearly, and being proactive in unblocking yourself and others. We want engineers who ask great questions, learn from their teammates, and know how to get what they need to do their best work.
