Job Title: Founding Full-Stack Engineer
Location | On-Site — San Francisco, CA
Time Zone | PST

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.

Key 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

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.
