About the role

We're hiring a Full Stack Engineer to help conceive, build, and ship new AI-powered products from the ground up. You'll work on early-stage product ideas that sit at the edge of what our models can do — moving from prototype to something real people rely on, often within weeks rather than quarters.

What they're looking for

  • 5+ years of professional software engineering experience, with demonstrated ownership across both frontend and backend systems
  • Strong track record shipping production web applications end to end, from data model and API design through polished user-facing interfaces
  • Comfort working in ambiguous, fast-changing environments where product direction is still being discovered
  • Experience making pragmatic technical tradeoffs to move quickly without accumulating unmanageable risk
  • Experience building products on top of large language models or other frontier AI systems, including working around their quirks and limitations
  • A strong product sense — you enjoy figuring out what's worth building as much as how to build it
More about this role

The mission of Thinking Machines is to build AI that extends human will and judgment. We are training frontier models with Inkling, developing Tinker to let people make models their own, and crafting interfaces that broaden human-AI communication. We believe the future worth building is human, and we're hiring people who want to build it.

You'll work on early-stage product ideas that sit at the edge of what our models can do — moving from prototype to something real people rely on, often within weeks rather than quarters.

This role sits at the intersection of product, design, and research. You'll partner closely with researchers to translate emerging model capabilities into interfaces and experiences, and with product and design to figure out what's worth building next. You'll frequently be the first engineer on a given idea, which means real ownership over both the technical direction and the product itself.

We're looking for someone who is energized by ambiguity, comfortable working across the entire stack, and motivated by getting new things in front of real users...
