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.

The Role

We are looking for a Senior SDK Engineer to join our team to help design, build, ship, and support end-to-end features and products that will help developers make more money. We want to bring somebody onboard that is product focused, customer focused, and passionate about building mobile SDKs with a great developer experience.

This role will primarily focus on either our iOS or Android SDK (depending on your core experience), but also requires contributions to our other platform + hybrid SDKs, from time to time. Experience in these other platforms is not a requirement but the desire and excitement to work on them is.

About you:

• You have 8+ years of experience in software, and have shipped mobile apps to Apple App Store or Google Play Store
• You are very experienced in Swift and Swift UI (iOS) or Java/Kotlin and Compose UI (Android)
• You are not afraid of iOS, Android, cross platform, or hybrid platforms.
• You love making products for developers.
• You love shipping good products.
• You have deep empathy for customers.
• You know how to ship high quality code using good testing practices in iterative cycles.
• You collaborate well with others and can communicate effectively in a fully-remote culture.
• You are proactive. When you see something broken, you jump on it to fix it or suggest improvements.
• You move fast, test, and iterate quickly.
• You ask questions when you're stuck on something.
• You are excited to be part of a growing team.

Bonus:

• You have experience building SDKs.
• You have experience in server driven user interfaces.
• You have shipped your own app to Google Play or the App Store.
• You have experience in Python or other backend development.

In the first month, you'll:

• Learn about our customers, our SDK, the in-app subscription ecosystem, the problems RevenueCat helps solve, and how our SDKs fit into that.
• Open your first pull request and deploy changes to be used by 32,000+ apps.
• Onboard into our codebase by working on your very first project and shipping it 😺
• Learn how we maintain as much transparency as possible with our work in GitHub.
• Begin reviewing code and add to our engineering culture.

Within the first 3 months, you'll:

• Be able to scope and work on projects self-sufficiently.
• Participate in code reviews, and contribute in other ways (testing, visibility, etc.) to improve reliability and quality of the codebase.
• Understand every product owned by your team.
• Understand and improve many of the codebases that the team works with.

Within the first 6 months, you'll:

• Be the most knowledgeable person on several key features.
• Have your own initiatives for improving the code base and our infrastructure.
• Contribute to the team roadmap and technical direction.
• Have shipped a major product or feature.

Within the first 12 months, you'll:

• Know more about mobile subscriptions than anyone ever should.
• Use your knowledge to contribute ideas to RevenueCat’s suite of solutions.
• Be able to spec, architect and build any feature we might want to build.
• Have experience in all areas of technology stack related to SDKs and be the primary expert/owner of at least one area.
• Help mentor and onboard new engineers, shaping the RevenueCat engineering culture as we continue to expand the team.
• Help prioritize the roadmap to provide maximum value to developers, while pushing the team and technology forward.

What we offer:

• Competitive equity in a fast-growing, Series C startup backed by top-tier investors, including Y Combinator
• 10-year window to exercise vested equity options
• A fully remote environment designed around autonomy and flexibility
• 4-5 weeks of flexible time off annually
• Paid desk at a co-working space
