Full Stack Engineer

About Us

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.

The Role

As a Fullstack Engineer, you’ll design and build the core systems that power Surge’s platform — the tools and interfaces that let humans shape frontier AI models. You’ll work across the stack to make data collection, labeling, and evaluation seamless and scalable, owning everything from product design decisions to backend architecture.You’ll partner closely with product, research, and operations to create fast, reliable, and delightful tools that help the world’s top AI labs train safer, smarter, and more capable models. This role is ideal for someone who loves moving quickly, cares deeply about product quality, and thrives in high-ownership environments.

What We're Looking for

• Experience building and maintaining fullstack applications using React/TypeScript and Python or Ruby on Rails.
• You care about the intersection of performance, usability, and maintainability, and you design systems that are simple, scalable, and resilient.
• You translate technical concepts clearly, enjoy working cross-functionally, and have a bias for shipping.
• You take ownership from idea to production, iterate fast, and write code that stands the test of time.
