Who You Are:

We’re looking for senior full-stack engineers who lean front-end and enjoy the ambiguity, speed, and ownership typical of small product teams. In this role, you’ll work across surfaces — from user-facing web apps to internal design systems — with a focus on delivering high-quality interfaces that support a range of Ai2 initiatives.

You’ll work closely with engineers, researchers, designers, and leadership to understand needs, define solutions, and execute. We value pragmatism and collaboration over rigid process, and we expect engineers to help define what gets built — not just how.

• Leads with empathy and builds strong relationships. You collaborate with humility, support your teammates, and take pride in helping others succeed — whether it's mentoring, code review, or pairing.
• Stays grounded in fast-moving contexts. You ...
