Handshake AI builds the training data that frontier labs use to push their models forward. A growing share of that work is in reinforcement learning: realistic, end-to-end environments where models can be evaluated and trained against real-world workflows. We’re hiring a Senior Product Manager to own the product surface that turns environment creation from a bespoke, weeks-long lift into a repeatable factory.

Today, building a single RL environment is a substantial cross-team effort involving dozens of manual steps across operators and engineers, and depends on tribal knowledge across data sourcing, de-identification, synthetic data generation, tool building, packaging, and quality assurance. Frontier labs are asking for environments across many verticals at once, and the manual model doesn’t scale. Your job is to make it scale: design and ship the platform that compresses lead time, replaces hand-built workflows with self-serve tooling, and lets a small team of operators turn out high-quality environments for any vertical our customers prioritize.

You’ll sit at the bridge between Operations and Engineering. Operators are running data pipelines locally, manually de-identifying datasets, manually QA’ing tools, and chasing customer deliveries. You’ll translate that work into a product roadmap, partner with our engineering leads on architecture and execution, and keep our research, GTM, and customer-facing teams aligned on what good looks like.

This is a high-leverage, 0→1 role inside a fast-moving research-adjacent product space. You’ll work cross-functionally with Forward Deployed Engineering, Operations, Research, Design, and GTM, and your work will directly determine how many environments Handshake can ship, how fast, and at what quality bar.
