About the job

💖 About Heartbeat

Heartbeat (heartbeat.chat) is a plug-and-play online community builder. Think "Shopify for online communities". We're building a world where people have the power to own & shape the way they engage with others online.

Heartbeat allows creators, coaches, & online experts to build a thriving community business — with discussions, courses, payments, events, documents, workflows, matchmaking. directories & more — all on their own website.

⭐ Why this job is special…

You'll be one of the first engineers to join the company—but you're joining a product & codebase that works. We have hundreds of customers processing thousands of dollars every month. All the leverage and autonomy of being an early engineer without the burden of building everything from scratch.
You get to work with people who know their craft. Everyone at Heartbeat is exceptionally skilled and brings deep experience from their previous roles.
We take Typescript seriously. If you're passionate about pragmatically applying type systems & functional patterns, this is the place for you. More about our approach
AI agents are here & we're ready to use them as a force-multiplier. We've spent a lot of time building incredibly expressive & flexible application building blocks. AI will let us double down on these through MCP and agentic configuration, giving us the magic of tools like Replit & Lovable without the brittleness.

Lead React Native development while contributing across our full TypeScript stack—React web frontend, NodeJS backend, and shared business logic
Work closely with the team to scope & prioritize new features
Write modular, maintainable, thoughtful code
Create rails to enable AI coding agents to robustly make changes & develop new features
