San Francisco, California, United States

Senior Full-Stack / Product Engineer

 Job Description:

THE OPPORTUNITY

Multiple venture-backed AI and enterprise-software companies are hiring product-minded engineers to own customer-facing systems from concept through production.

WHAT YOU WILL DO

  • Build and ship end-to-end product features across modern frontend, backend and data layers.
  • Own projects from problem definition and technical design through launch, measurement and iteration.
  • Work closely with founders, product leaders, designers and customers to translate ambiguous needs into reliable software.
  • Make pragmatic architectural decisions that balance speed, quality and long-term maintainability.
  • Use modern AI development tools and, where relevant, integrate LLM or agentic capabilities into production workflows.
  • Raise engineering standards through thoughtful reviews, testing, observability and operational ownership.

WHAT WE ARE LOOKING FOR

  • Strong production experience building full-stack web applications in a high-velocity product environment.
  • Depth in TypeScript/JavaScript and a modern frontend framework such as React or Next.js.
  • Backend experience with Python, Node.js, Go or a comparable language, plus relational databases and APIs.
  • Evidence of owning meaningful products or features from 01 or through major scale-up.
  • Comfort operating with incomplete requirements, rapid iteration and direct business accountability.
  • Clear communication and the ability to work effectively with technical and non-technical stakeholders.

PREFERRED BUT NOT ESSENTIAL

  • Early-stage or founder-level ownership experience.
  • Experience with AI-native products, LLM applications or data-intensive SaaS.
  • Cloud infrastructure, CI/CD, observability or distributed-systems exposure.
