Senior Software Engineer, Product

RevenueCat removes the headaches of building and scaling in‑app subscriptions. Since graduating from YC’s S18 batch we’ve grown into the default monetization platform for mobile: we’re in >40% of newly shipped subscription apps, we process $12B+ in annual purchase volume, and we help everyone from a solo dev in Brazil to the OpenAI mobile team understand and grow their revenue.

We’re a remote‑first crew of 150+, spread across 25+ countries, and guided by values we actually practice: Customer Obsession, Always Be Shipping, Own It, and Balance. If you want your work to touch hundreds of millions of end‑users (and help the developers behind them get paid), you’ll fit right in.

We are looking for a Senior Software Engineer, Product to design, build, ship, and own end-to-end product features used by thousands of developers and hundreds of millions of end-users.

This role is product-focused, but deeply technical. You’ll work across frontend, backend, and data boundaries, making thoughtful tradeoffs to deliver reliable, high-quality systems. You’ll be expected to take ownership from problem definition through production rollout and long-term maintenance.

“Product-focused” at RevenueCat means pairing strong engineering fundamentals with good judgment — not trading correctness, reliability, or scalability for speed.
