You’re an experienced engineer who can deliver high-quality product work, communicate clearly, and make good trade-offs. You enjoy collaborating with product and design, and you care about maintainability, performance, and user experience. You can own the outcomes of large and complex technical work, guiding a small team to success. You are excited about boosting your work through AI agents, without losing sight of quality outcomes.

Because we are a remote company, communication is a vital skill. We prefer people that over-communicate and are willing to respond quickly.
