Senior Software Engineer, Agents

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

RevenueCat helps app developers manage subscriptions and make more money from them. Maybe you're an indie developer who doesn’t know what "conversion" even means, you just want your app to make money so you can keep building it. Or maybe you're a growth specialist at a company doing millions a month, and pricing experiments are already your whole job. Either way, you probably didn't get into this to spend your days staring at a dashboard. So we built two AI agents to do that work for you, or make you even sharper at it if you're already a pro.

Enter Rico. Rico watches over your subscription business and can help you make sense of it, and act on what it finds. Say your revenue dropped last week. You don't need to go digging through charts to find out why. Just ask Rico. It pulls the data, explains what happened in plain language, and shows you how you compare to similar apps. Then it can fix things itself, like setting up a new plan or restoring a customer's access, with you approving the change before it goes live. Run a pricing experiment and Rico will read the results for you and tell you which version is winning. There are so many things we want Rico to be able to do!

Then there's our AI Paywall Editor, a specialized agent to build and edit paywalls, the screen that asks someone to subscribe. Most developers are not designers, and a paywall that actually gets people to tap "subscribe" is harder to build than it looks, so the AI Paywall Editor helps you with that. Use it in our online editor, from the command line, or hook your own AI tools into it over MCP.

This is a role for engineers who've built advanced agents that do actual work , not just a thin wrapper around an LLM. You'll ship agentic features to thousands of developers, and you’ll shape the foundation everything else runs on: orchestration, tool execution, context management, evaluation and human-in-the-loop controls.

About You

You have 8+ years of experience shipping production systems.

You've built agents that other people actually use and the systems around them: tool use, structured output, context management, evaluation, orchestration.

You have strong backend fundamentals. You've built systems that need to be reliable, observable, and secure.

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 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 an founder:: you notice problems, propose improvements, and follow through fast.

You're comfortable with ambiguity. This is an early stage product inside a growth stage company, and the architecture is still being figured out.
