Job description

Employer stated. Engineering lead for Aptos’s payments unit: the Payment API, partner integrations, revenue attribution, and the first two hires. The posting calls payments a ring-fenced unit with its own P&L.* The Aptos Payment API. Spec, ship, and run the single API businesses integrate against — wrapping partner infrastructure today, with an orchestration engine routing across a licensed partner network as the business earns it. You write the spec bottoms-up from partner and client requirements.* Partner-facing engineering. You are the technical face of the unit: requirements intake, integration leadership, and technical diligence with banks, EMIs, PSPs, stablecoin issuers, and e-wallet platforms. You can run those calls alone and write the requirements doc after.* The trust infrastructure. Revenue attribution and reconciliation (the system that proves which volume is ours), a single-window KYC/KYB integration, a testnet sandbox that lets any prospect try the stack before compliance onboarding, and a native-asset-only settlement policy — no bridges.* Integration with the trading stack. Our trading team builds the RFQ liquidity and tokenized-FX systems; you own the payments side of that seam — routing corridor FX through their venue, defining the API contract between the two systems, and making the handoff invisible to clients.* The team and the calls. Hire and lead the first two engineers; grow the team only as revenue triggers fire. Make the build-vs-buy decisions (orchestration components, KYC tooling) with written memos at each gate.
