Founding Design Engineer

Sim is talent-dense. We're looking for special people who are mission-driven, passionate, and creative.

We're a team of 10 working full-time, in person in San Francisco. We have a flat organization: you'll work directly with the founders and own your work from idea to execution. We sponsor visas.

Design engineers own the feel of Sim and the code that brings it to life. You'll combine strong engineering fundamentals with design taste to take interfaces from early exploration to production: defining interaction models, building prototypes, and shipping performant, accessible code. You'll work across component architecture, application state, and the details of motion and layout to make complex agent workflows feel intuitive. What you learn from users will shape both the product's design and its implementation.
