About the role

Key responsibilities & impact

Take financial partnerships from zero-to-one: scope the integration with the partner, pressure-test data and protocol specs, design the system, build it, ship it, and operate it.
Own the technical relationship with Replit's financial partners across the full lifecycle: billing platforms, payment processors, agentic-commerce protocol partners, tax/compliance vendors, KYC/risk providers.
Build and maintain Replit's integrations with agentic-commerce protocols (ACP, UCP, MPP) and Shared Payment Tokens, so Replit Agents and the apps Replit users ship can transact across AI surfaces.
Design the abstractions that let other Replit engineers monetize new products without each one having to relearn the partner stack; clear seams, versioned interfaces, and integrations that age gracefully.
Build the observability layer for partner-facing flows: webhook reliability, reconciliation, latency SLOs, partner-incident response, and the dashboards that let us see partner failures before users do.
Drive partner-side incident response when integrations degrade, including escalation paths, post-incident reviews with the partner, and the eng work to harden the integration so the same class of failure doesn't recur.
Represent Replit in technical reviews with partners: API design feedback, protocol input, joint roadmaps. Bring what you learn back into Replit's monetization architecture.
Partner closely with finance, accounting, data, legal, and BD so the integrations you build produce auditable financial data, satisfy contractual SLAs, and unlock the commercial deals behind them.

Requirements

What you’ll need

6+ years of professional software engineering experience, with strong backend expertise.
Direct, hands-on experience integrating with at least one external financial-partner platform end-to-end, but owning the integration through go-live and steady-state operation. Examples include payment processors, billing/metering platforms, tax engines, KYC/risk vendors, banking-as-a-service providers, or card-issuing platforms.
Track record of taking integrations from zero-to-one: scoping with the partner, navigating ambiguous specs, and shipping a production-grade integration that you then had to operate.
Strong system-design instincts in high-correctness domains where money, idempotency, retries, reconciliation, and observability are first-class concerns.
Comfort working autonomously across organizational boundaries. You can drive a meeting with a partner's engineering team, push back on a bad spec, and still leave with a relationship intact.
Excellent debugging skills against systems you don't own, including reading partner API behavior from logs, replays, and webhook traces when documentation is wrong or incomplete.
