Role Overview:
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.

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
Required Qualifications:
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
Preferred Qualifications:
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
Tools & Technology:
Modern frontend frameworks
Backend/API frameworks and databases
Cloud infrastructure and deployment tooling
AI-assisted development tools
We connect top talent with vetted employers, competitive pay, and real growth opportunities.
