Founding Product Engineer (AI Infrastructure Startup)

An early-stage startup rebuilding email-style messaging for AI agents wants someone to be its first product engineer on the founding team. Working shoulder to shoulder with the founders, this person decides what the product is like for developers creating ambitious agents, from their first account through to live deployment, and sets the tone for how engineering is done.

Your focus

• Create product features across every layer: refined front-end work, APIs, services, schemas and infrastructure
• Speak with developers regularly and mine support threads and usage metrics to learn where they run into trouble
• Convert ill-defined customer pain into released product, with a say in the question of what to make and not only how
• Prototype fast and refine the journey developers take from registration to running in production
• Help define engineering habits and design quality bars as among the first hires

Who thrives here

• Roughly three to seven years as a product or full-stack engineer
• Proof that you have taken projects from nothing to launch, starting with a customer problem and ending with shipped software
• Full-stack depth spanning interfaces, APIs, backend systems, databases and queues
• Time at a fast-growing startup (seed through Series B); founding or early-team experience counts for a lot
• High agency and sound taste in product and design, rather than waiting for specs or mockups
