Software Engineer, Money Platform

OpenRouter

Remote · United States$17,917–23,750 gross/mofull-timeOpenRouter Careers

We're hiring our first engineer to envision, build and own the dollar+token value capture engine behind OpenRouter's leading inference gateway, marketplace and rapidly growing suite of agentic products. You will be responsible for the robust and flexible platform that lets the business sell any pricing model it can dream up.

Responsibilities

  • Flexible pricing and contract terms. Any commitment size, BYOK pricing, overages, platform fees and per-seat pricing. Sales and CS should be able to test new deals without an engineer.
  • Automate quote-to-cash. Take a signed contract straight to a provisioned, correctly billed customer with no manual uploads. Handle POC and production contracts as separate flows.
  • Build credit transfers at onboarding and self-serve credit grants for CS into our own tools.
  • Define the source of truth. Financial core that owns fees, plans and entitlements. Establish robust data architecture for internal and customer reporting.
  • Own usage → revenue. Every completed request is metered, priced and recorded exactly once, across our streaming spend-tracking pipeline and usage records. Reconcile what we served against what we charged.
  • Own billing, payments & collections. That means invoicing, prepaid credits, auto top-ups, refunds, tax/VAT, POs and spend-against-commitment tracking. It also covers the Stripe integration, failed-payment recovery and overdue-invoice collections.
  • Build the ledger, AP & reconciliation.
  • Build a double-entry ledger as the financial system of record. Automate reconciliation across Postgres, Stripe, billing and usage data.
  • Own provider settlements and payables, and hand Finance close-ready numbers.
  • Work cross-functionally.
