Founding Full-Stack Engineer

San Francisco, CA — On-site (5 days/week)

We’re partnering with an exciting early-stage startup that’s revolutionizing AI-powered code review. Having raised $1.3M in pre-seed funding with a seed round planned for this summer, the company is growing rapidly—adding 40 new clients this month alone—and building a team of passionate engineers to deliver their full product roadmap.

About the Opportunity:

Join as a founding engineer in a small, nimble team led by experienced, repeat founders who know the startup ecosystem inside out. This is a unique chance to own features end-to-end, move fast, and shape the technical direction from the ground up.

What We’re Looking For:

• Engineers who thrive in early-stage startup environments
• Proven ability to take full ownership of features and deliver quickly
• Senior or principal-level experience preferred, but motivated new grads from top CS programs with a strong fire and solid fundamentals are encouraged
• Flexible on tech stack and years of experience; passion, adaptability, and ownership mindset matter most
• Mission-aligned individuals excited by building impactful AI tools

Tech Stack Highlights:

• Full-stack TypeScript (React frontend, backend)
• Zero-sync framework for superhuman performance
• PostgreSQL database

Daily Work Environment:

• Collaborative and flexible; weekly planning to assign ownership on features
• Two cofounders currently, experienced engineering team growing
• Need strong self-starters who can stand on their own and push the product forward

Compensation & Benefits:

• On-site work in San Francisco, no current visa sponsorship (exceptions for exceptional candidates)

Ideal Candidate:

• 3-5 years experience in early-stage startups (flexible for strong candidates)
• Comfortable working full-stack or primarily frontend/backend
• Excited by fast-paced startup life and building impactful products
