Role Overview

We're looking for a Senior Full Stack Engineer to help design, build, and ship core parts of our product. You'll work across the entire stack, with a strong emphasis on crafting polished, intuitive user experiences, while also building reliable backend systems and integrating AI deeply into the product.

We’re an early stage full of energy team. Everyone wears multiple hats, moves fast, and cares deeply about what we're building. We need someone with a product mindset: not just an engineer who executes specs, but someone who thinks about why we're building something and how users will experience it.

What You'll Do

  • Build and own end-to-end product features across the full stack.
  • Design and implement clean, high-performance user interfaces. This is where your craft shines.
  • Develop and maintain robust APIs and backend services.
  • Integrate AI agents and LLM-powered workflows into the product.
