Product Manager, Handshake

• 3+ years as a product manager shipping production code with engineering teams
• Experience with payments, payroll, billing, or another money-movement product where bugs have real financial consequences
• A track record building tools for internal users like finance, operations, T&S, or similar
• Comfortable reasoning across systems with many inputs and dependencies (KYC, tax forms, IP data, device fingerprints, project allocations, audit logs)
• Data-informed and action-oriented. You use precision/recall, payout error rates, and on-call volume to prioritize, and you move quickly once the signal is clear

Desirable

• Handshake AI matches domain experts with leading AI companies to train frontier models
• We're hiring a Product Manager for our Pay & Safety squad to own how we pay our fellows and how we keep our marketplace trustworthy
• Tens of thousands of fellows rely on HAI to pay them accurately and on time every week
• The Pay team has built the foundation, including admin-managed payroll, referrals at scale, and incentives tied to pipeline stage, but the surface area is growing faster than the team can keep up with
• You'll own the roadmap for what's next, including withholding tax compliance, off-platform time tracking, in-product adjustments, international payouts, and securing payroll against fraud
• You'll also lead the team's expansion into Trust & Safety. Fraud detection at HAI today is largely manual
• Operators run queries by hand and react after customers flag bad actors. The gap costs us millions of dollars per month between payouts to fraudsters, false-positive churn, and lost revenue. Your job is to move detection from reactive to proactive: ingest the relevant risk and trust signals, build the system that acts on them, and give operators tooling that replaces the manual work they do today
• You'll be part of a cross-functional squad with engineers and designers, working closely with Operations, Finance, T&S, and Growth
• Pay platform. The roadmap for accurate, on-time pay. Active areas include payroll automation (replacing the Hex workflow with the admin dashboard), withholding tax support, in-product adjustments and incentives v2, off-platform time tracking for Otter and Moose, and HAI international payouts
• Trust & Safety platform. Build out HAI's proactive fraud detection system. This covers ingesting 50+ risk and 10+ trust signals (in Cinder and internally), launching a Fraud Center, guided PII verification flows by risk level, automated actioning, and IP/VPN/persona improvements
• Operator tooling for Pay & Safety. Our team currently fields pay disputes and runs fraud queries manually. Your job is to build the dashboards, status systems, and self-serve flows that reduce that work
• Goals and metrics. Define and track targets including: % of payouts executed without manual adjustment, weekly withholding tax exposure, monthly referrals, customer-flagged fraud rate, fraud detection recall and precision, median time to verify, and % of verifications automated
• Cross-functional partnership. Work with Finance on payroll and tax, with T&S on signals and policy, with Growth on referrals GTM, and with sibling squads where workflows overlap
