About The Position

We are seeking a Founding Full-Stack Engineer to join the earliest technical team at a fast-moving AI video infrastructure startup. The company's first product turns prompts and documents into whiteboard-style explainer videos in seconds, with a broader vision to make video generation fast, cheap, and programmable enough for AI to use video anywhere it uses text today. This is a founding engineering hire responsible for shaping the core product across the entire stack, from user-facing features to backend systems. The ideal candidate thrives on ambiguity, moves fast, and takes real ownership of outcomes rather than waiting for a fully-scoped spec. You will work directly with the founder and help define how engineering operates from day one.

Requirements

  • Strong full-stack engineering background with modern web applications
  • Experience with typed languages, frontend frameworks, backend APIs, databases, and cloud services
  • Solid product instincts and ability to simplify complex workflows for users
  • Comfortable shipping quickly while maintaining reliability on critical paths
  • Strong ownership mentality from problem definition through launch
  • Comfortable using AI tools to move faster, while relying on personal judgment to define and solve problems
  • Must be willing to work on-site in San Francisco, CA

Nice To Haves

  • Prior experience at an early-stage startup or founding engineering team
  • Experience operating without a formal ticket queue or fully-defined spec
  • Comfortable working across product, design, and infrastructure simultaneously

Responsibilities

  • Design and ship features spanning frontend, backend, and infrastructure
  • Build APIs and workflows for accounts, projects, billing, and collaboration
  • Create frontend experiences that are fast, intuitive, and reliable
  • Improve onboarding, account visibility, and overall developer experience
  • Collaborate closely with product, design, and customers to prioritize work
  • Write clean, maintainable code and documentation for the team to build on
