Senior Software Engineer, RevenueCat

• You have 5+ years of experience shipping production systems
• You have hands-on experience building with LLMs — not just prompting, but building 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 are comfortable with ambiguity. This is an early-stage product inside a growth-stage company. The architecture is still being figured out
• You are self-directed. You figure out what needs to be built, build it, and ship it
• You collaborate well with others and can communicate effectively in a fully-remote culture

Desirable

• We're building an AI assistant that helps developers understand and grow their subscription revenue. It lives in Slack today and is expanding to our dashboard and API. It can pull real-time data, evaluate experiments, debug integrations, and explain what's happening in your app using natural language
• We see a future where the majority of a user's interactions are either intermediated or automated by our agent
• We're a team that's historically built deterministic CRUD systems, and we need an engineer who can build the foundational agent infrastructure that everything else runs on: orchestration, tool execution, context management, evaluation, and the trust layer that lets us give an agent increasing autonomy over things that matter
• In the first month, you'll:
• Ship your first agent feature and get familiar with the architecture, tool ecosystem, and how Rico talks to RevenueCat's APIs
• Identify the biggest reliability or performance gap and start fixing it
• Meet with the team, get set up with repos, dev environment, and debugging tools
• Familiarize yourself with RevenueCat dashboards, logging, debugging tools, cloud providers, infrastructure management and general architecture
• Within the first 3 months, you'll:
• Launch a brand new agentic feature to tens of thousands of developers
• Own a core infrastructure area — orchestration, eval pipeline, tool framework, or the trust/permissions layer
• Be able to scope and work on projects self-sufficiently
• Learn the basics of incident response and be part of the on-call rotation
• Within the first 6 months, you'll:
• The agent is measurably more reliable, faster, and capable because you're here
• You've built infrastructure that the rest of the team ships agents with
• Review code, create proposals, and contribute to architectural discussions
• Have shipped a major product or feature
• Within the first 12 months, you'll:
• RevenueCat is an AI-native company. You built the engine underneath it
• Know all the major components of our agent system and be able to debug complex issues
• Have your own initiatives for improving our agent products, understanding the current issues and priorities
• Mentor other engineers joining the team
