Senior/Staff Software Engineer - Commerce Platform

Commerce Platform Engineer The Commerce Platform is one of the most consequential systems at Suno - it's where every product decision about value becomes real. We're looking for a detail-obsessed engineer to own our commerce platform end-to-end: the billing, subscription, payment, and metering services that power how Suno makes money, and the surrounding systems that keep it correct - entitlements, involuntary churn recovery, fraud prevention, and accounting. You'll set the technical direction, be a key voice in how we think about the future of our revenue model, and build infrastructure that has to be exactly right at scale. Responsibilities: Own Suno's commerce platform across web and mobile, including our vendor integrations and the core billing, subscription, payment, and metering services. Build and evolve subscription and entitlement management - the source of truth for what every user has paid for and what they get access to. Own payment methods and payment processing, expanding how users around the world can pay for Suno. Recover revenue that would otherwise be lost: own involuntary churn (failed payments, dunning, recovery flows) and fraud prevention. Build the financial correctness layer - accounting and reconciliation systems where the money has to be exactly right. Lead the evolution of our billing architecture - including an in-progress migration to a modern ledger-based model - making it more maintainable and easier to reason about as the business grows. Participate in product and strategy discussions about how Suno monetizes, bringing technical judgment to decisions that have direct revenue impact. Build tools, systems, and interfaces that give the broader team more leverage to build products and perform analyses. Requirements: 5+ years of backend engineering experience, ideally building systems where being wrong has immediate real-world consequences - payments, financial infrastructure, distributed systems, or similar. A natural instinct to think about failure modes first: what happens if this event arrives twice, out of order, or not at all? Strong product sense alongside technical depth - you care about what users experience, not just what the code does. A high bar for correctness that you hold yourself and others to without being told. Bachelor's degree in Computer Science or equivalent experience. Experience with Stripe, RevenueCat, or payments/fraud systems is a plus. A love for music is a huge plus.
