We're a stealth-mode startup in San Francisco, building transformative applications at the edge of Generative AI. We're backed by top-tier investors and looking for a sharp, hands-on Founding Engineer to help shape our product, infrastructure, and culture from the ground up.
The Role:
As a Founding Engineer, you'll be at the heart of everything - architecture, code, product strategy, and scaling.

- Own and ship full-stack features using Python, JavaScript, and TypeScript
- Help make early tech decisions, set engineering standards, and build internal tooling
- Contribute actively to model experimentation, prompt engineering, and fine-tuning
- Collaborate closely with product and design to iterate quickly
Requirements:
- 3-5 years of hands-on software engineering experience
- Strong startup experience - you've thrived in fast, ambiguous environments
- Active GitHub or portfolio of personal/open-source projects
- Deep experience with LLMs / GenAI APIs (OpenAI, Claude, etc.)
- Fluency in Python and front-end technologies (JavaScript/TypeScript, React preferred)
- Comfortable working onsite in San Francisco, 5 days a week
- Excited by the builder mentality - shipping fast, learning faster
Nice to Have:
- Experience deploying ML models or working with vector databases
- Contributions to open-source GenAI projects
- Previous early-stage or founding engineer experience
