As our product reaches more customers, we need the commercial systems that make product access, pricing, and revenue reliable. You will build the backend foundation that turns customer accounts and product usage into clear plans, accurate bills, successful payments, and correctly provisioned access.\nThis is a SaaS monetization role focused on accounts, subscriptions, billing, payments, and entitlements. It is not an ads monetization role, and it is not primarily a cloud infrastructure or agent-runtime role.\nWhat you'll do\nOwn the domain models and APIs for customer accounts, organizations, workspaces, plans, pricing, trials, seats, and entitlements\n\nBuild subscription and usage-based billing systems, including metering, aggregation, invoicing, credits, proration, upgrades, downgrades, cancellations, and recovery flows\n\nIntegrate Stripe and future payment providers across checkout, recurring payments, payment failures, refunds, disputes, and provider webhooks\n\nDesign robust payment and billing state machines that are idempotent, replay-safe, observable, and resilient to duplicate, delayed, or out-of-order events\n\nBuild trustworthy financial records, reconciliation workflows, audit trails, and internal tools for resolving account and billing exceptions\n\nPartner with product and customer-facing teams to translate commercial requirements into simple, maintainable systems and customer experiences\n\nSet a high bar for correctness and operational ownership in systems where a wrong charge or missing entitlement directly affects customer trust\n\nYou might be a fit if\nYou have a BS/MS in Computer Science or equivalent experience and 5+ years of backend engineering experience\n\nYou have built production systems for B2B SaaS, e-commerce, fintech, or another transaction-heavy product\n\nYou have hands-on experience with Stripe or a comparable payment provider, including webhooks, payment lifecycle events, and failure handling\n\nYou can model complex business domains such as accounts, subscriptions, orders, invoices, payments, usage, and entitlements\n\nYou understand idempotency, transactional consistency, money precision, reconciliation, auditing, and safe data migration practices\n\nYou are strong with relational databases and production API design, and you can reason clearly about correctness under retries and partial failures\n\nYou have a bias for action, communicate clearly, and enjoy owning an ambiguous 0 to 1 domain end-to-end\n\nBonus: experience with usage-based billing, revenue operations, tax or invoicing systems, multi-currency payments, or financial ledgers","description_format":"text","description_chars":2860,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI
