RevenueCat is a platform that helps developers build and grow their subscription-based apps by simplifying in-app purchase management across iOS, Android, and the web. Trusted by over 32,000 apps, RevenueCat offers a suite of tools for subscription data management, customer support, marketing, and engineering teams. The platform enables businesses to implement in-app purchases faster, automate receipt validation, and provide a central source of truth for subscription data.

With its comprehensive API, RevenueCat facilitates the integration of subscriptions with existing marketing and analytics tools, allowing developers to focus on building impactful app features.

📋 Description

• Building an AI assistant that helps developers understand and grow their subscription revenue. • Ship 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, debugging tools. • 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. • Review code, create proposals, and contribute to architectural discussions. • Have shipped a major product or feature.

🎯 Requirements

• 5+ years of experience shipping production systems. • Hands-on experience building with LLMs — not just prompting, but building the systems around them: tool use, structured output, context management, evaluation, orchestration. • Strong backend fundamentals. Built systems that need to be reliable, observable, and secure. • Comfortable with ambiguity. This is an early-stage product inside a growth-stage company. The architecture is still being figured out. • Self-directed. You figure out what needs to be built, build it, and ship it. • Collaborate well with others and can communicate effectively in a fully-remote culture. • Bonus: • Experience with OpenAI/Anthropic APIs specifically. • Built agents that other people use. • Experience with evaluation and observability frameworks (Langfuse, Langchain, etc). • Familiarity with subscription business models, app stores, or developer tools. • Built Slack integrations or other conversational interfaces. • Contributions to open-source AI/ML tooling.
