The team is passionate about giving people the power to own and shape the way they engage with others online.

The client is a plug-and-play online community builder. Think “Shopify for online communities”. The company is building a world where people have the power to own & shape the way they engage with others online.

The platform 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…

• The successful candidate will be one of the first engineers to join the company—but will be joining a product & codebase that works.

This role offers all the leverage and autonomy of being an early engineer without the burden of building everything from scratch.
• The team consists of individuals who know their craft. Everyone is exceptionally skilled and brings deep experience from their previous roles.
• Typescript is taken seriously. If a candidate is passionate about pragmatically applying type systems & functional patterns, this is the place for them.
• AI agents are here & the company is ready to use them as a force-multiplier. Significant time has been spent building incredibly expressive & flexible application building blocks. AI will allow the team to double down on these through MCP and agentic configuration, providing the magic of tools like Replit & Lovable without the brittleness.
