Senior Software Engineer - AI Data (USA)

Frontier AI labs are building coding agents that do real engineering work. Before these coding agents ship, Senior Engineers have to work a real problem from a codebase they know, step by step, to identify where a frontier model goes wrong then correct it.

Not just anyone can do this. It takes a select group of engineers with experience and taste.

Engineers who qualify join a fixed-pay contract: earn $6,000/wk for 40hrs of work ($150/hr). Work on your own schedule, paid weekly.

  About Handshake

Handshake was founded on a simple belief that everyone deserves a path to a great career, regardless of where they went to school or who they know. Today, we power 25 million job seekers, 1 million+ employers, and 1,600 educational institutions.

In 2025, we started Handshake AI and built the fastest-growing AI data business in history. We work directly with frontier AI lab researchers to create evaluations, publish benchmarks, and push the boundary of data. We’ve grown from $0 to ~$1B run rate and pay ~$60M to over 30K individuals every month.

Human data is the core infrastructure to AI advancement. Frontier AI labs currently improve model capabilities with various data-intensive post-training techniques. We believe that data spend for AI training will increase by 3-5x in the next few years and continue for much longer as models take on new domains. Handshake AI supports all of the frontier AI labs, working on their most complex data at the largest scale.
