Senior SDK Engineer

RevenueCat gives app businesses the infrastructure and tools to build, run, and improve their monetization. Since graduating from YC’s S18 batch, we’ve grown into the default monetization platform for mobile. We’re in 50%+ of newly shipped subscription apps, we process $16B+ in annual purchase volume, and we help everyone from a solo developer to the OpenAI mobile team understand and grow their revenue. We’re a remote-first team of 150+ people across 25+ countries, guided by values we actually practice: Customer Obsession, Always Be Shipping, Own It, and Balance. This isn’t the right fit for everyone. The systems you’ll build here manage billions of dollars and touch hundreds of millions of end users, and we don’t take that lightly. You’ll be expected to work hard and hold a high bar for what you ship, alongside some of the sharpest, most driven people you’ve worked with. If that sounds energizing rather than exhausting, keep reading.
