Revenue Cat 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 Open AI 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’re looking for a Backend Engineer to design, build, ship, and own end-to-end product features used by thousands of developers and hundreds of millions of end-users.

This is a hands-on IC role.

We want someone that loves shipping products, not just code.

You are an engineer obsessed with the customer and passionate about software.

You’ll take ownership from problem scoping to production rollout to long-term maintenance.

You have both the engineering fundamentals to write performant systems that operate at huge scale near flawlessly and the product sense that doesn't let “perfect” get in the way of “shipped today.”

About You

  • You have 8+ years of experience as a backend engineer designing complex, fast-growing systems that didn't exist before you.
  • You can write advanced SQL statements beyond basic SELECT and UPDATE statements.
  • You hold a high bar for quality and instinctively know which details matter, but also are discerning enough to cut scope when needed while still delivering value.
  • You’re customer-obsessed: you imagine yourself as the developer, product manager, or marketer using the feature or experiencing the issue.
  • You’re a builder, not an implementer: scoping, prioritizing, and driving rollout in partnership with our Product team.

This isn’t a role where you check off items from a detailed specification.

  • You can quickly familiarize yourself with code you didn't write yourself and improve it.
  • You're comfortable coding alongside AI tools like Copilot, Cursor, or Claude Code.

You use them to move faster on the parts that don't need your full attention, and you're detail-oriented enough to catch when they're wrong.

  • You’re scrappy and biased toward shipping. You’d rather ship a good version today and iterate than wait to ship a perfect one next quarter.
  • You communicate clearly, both in real-time and asynchronously. We’re a fully remote team, and how you write is as important as how you code.
  • You’ve shipped meaningful user-facing features to production, monitored their usage and adoption, and improved them over time.
  • You write high-quality, well-tested code, debug issues methodically, and help raise the engineering bar through thoughtful feedback and mentorship.
  • You act like a founder: you notice problems, propose improvements, and follow through fast.

Ideally, you have

  • Experience in Python.
  • Experience in Postgre SQL.
  • Experience building SDKs.
  • Shipped a mobile app with in-app purchases.
  • Some experience with React and SPA applications.

In the first month, you'll

  • Meet frequently with your team and mentor to get up to speed.
  • Set up and get familiar with repositories, task management, and the dev environment.
  • Implement and ship your first project.
  • Get familiar with Revenue Cat’s dashboards, logging, debugging tools, cloud providers, infrastructure, and general architecture.
  • Learn about the mobile app economy and subscription-business concepts that shape our product decisions.
  • Within the first 3 months, you'll
  • Scope and work on projects self-sufficiently, end to end.
  • Talk to customers or support directly to understand how the systems you own actually get used and where they break down.
  • Learn the basics of incident response and join the on-call rotation.
  • Participate in code reviews and contribute to reliability and quality across the codebase.
  • Understand every product your team owns.
  • Within the first 6 months, you'll
  • Review code, write proposals, and contribute to architectural discussions.
  • Contribute to your team’s roadmap and technical direction — the “why,” not just the “how.”
  • Be the go-to person on a couple of your team’s focus areas.
  • Have shipped a major product or feature, start to finish.
  • Within the first 12 months, you'll
  • Know all the major components of our system and be able to debug complex issues across it.
  • Have your own initiatives for improving our products, grounded in real customer and business priorities.
  • Spec and architect medium-to-large projects, gather feedback, and drive design validation and rollout plans.
  • Mentor other engineers joining the team.
  • Push the org to improve reliability, scalability, and performance.
