Software Engineer, Fellow Experience

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.

As a Software Engineer on the Fellow Experience team, you will build and scale full-stack systems that power the middle-of-funnel experience for fellows, from project discovery through successful onboarding.

You’ll work across frontend and backend surfaces to improve how fellows discover projects, apply, get matched, and onboard successfully. Your work will directly impact fellow volume, match quality, and conversion as we scale toward more intelligent automatic allocations.

This is a product-focused, full-stack role with real customer impact, close collaboration with product and design, and clear growth paths toward senior technical ownership.

The Fellow Experience team owns critical user journeys including the landing page experience for project invitations and applications, onboarding flows (confidentiality agreements, video/camera checks, educational programs, reading materials), project-specific assessments and recordings, and the internal tools that support manual matching.
