Staff Fullstack Engineer

Our mission is to raise AGI with the richness of human intelligence — curious, witty, imaginative, and full of unexpected brilliance.

Surge was founded by engineers and researchers who dreamed of building the next generation AI. We're building a platform that powers the most powerful models in the world in partnership with companies like Anthropic, Google, Microsoft, and Meta.

At Surge, we believe the path to AGI isn't just about scaling compute—it's about embracing the unlimited ceiling of human intelligence and creativity in the data that shapes these systems. Our platform combines elite human expertise with cutting-edge tools for scalable oversight, from building rich RL environments to conducting rigorous evaluations that go beyond benchmarks. We've run a profitable business from day one without raising venture funding.

This is a senior, hands-on engineering role for builders who want full ownership.

As a Staff Fullstack Engineer at Surge, you will design and build the core systems that power our platform, owning everything from frontend product decisions to backend architecture. You’ll operate with a high degree of autonomy, make consequential technical decisions, and ship quickly.

We are a small, dynamic team operating at the center of the AI ecosystem. You’ll collaborate closely with engineering leaders and ML practitioners from top technology companies to build fast, reliable, and scalable tools that support advanced AI training techniques.
