As a Senior Full Stack Engineer, you’ll lead the delivery of high impact product and platform work across the stack. We’re looking for someone with strong ownership, sharp product instinct, and the ability to use modern AI tooling to meaningfully amplify their output. This is a role for someone who goes beyond execution, quickly gets to the heart of the problem, challenges assumptions where needed, and delivers practical, high quality solutions with real impact.

In this role, you’ll work hands‑on across frontend and backend systems, help shape technical direction, and partner closely with product and design to build fast, pragmatic, high quality software ’ll also lead the design, architecture, and delivery of production ready AI applications at scale.

Hours of Work: Your core working hours will generally align with Eastern and Pacific time zones. However, as you'll also require partnering with colleagues across APAC occasionally, some flexibility will be required to enable effective global collaboration. We believe flexibility goes both ways, so you'll have the autonomy to structure your day in a way that balances collaboration, deep focus, and personal commitments.
