Founding Fullstack Engineer

Stealth Startup

Founding Full Stack Engineer

(AI for Commerce Company – fresh $10M in funding, on the verge of Series A)

Why Join Us?

We’re on a mission to revolutionize how we interact with the internet, powering AI-driven, personalized experiences for e-commerce and beyond. Picture a future where every website truly adapts to each user. With $5M newly secured and a Series A on the horizon, now is the optimal time to get in on the ground floor. You’ll help shape our product vision, build the tech from scratch, and drive the internet’s intelligence layer forward.

What You’ll Do

  • Create 0 to 1 Products – Architect and launch new AI-powered features at lightning speed without sacrificing quality.
  • Work with Cutting-Edge LLMs – Explore the latest AI models, refine retrieval systems, and shape the future of online experiences.
  • Craft Exceptional UX – Build interfaces that delight users, facing the unique challenges (and rewards) of integrating AI into production.
  • Operate with Ownership & Urgency – Take the reins from ideation to deployment in a fast-paced environment.
  • Collaborate in SF (or Fly In!) – Join our team in San Francisco—or visit as needed—to keep pace with big ideas and rapid iteration.

Why It’s Exciting

  • Massive Impact : As an early engineering hire, your work and decisions will literally define our technology, culture, and growth.
  • Perfect Timing : We just raised $5M and are heading swiftly toward our Series A—this is your chance to rise with us.
  • Leading-Edge Tech : Push the boundaries of AI, from model-based evaluations to next-generation recommendation systems.
  • High-Growth Environment : Join a team of doers and thinkers, where every line of code and every experiment can reshape an entire industry.

You’re a Perfect Fit If You…

  • Have built 0 to 1 products at early-stage startups or as a founder, balancing speed with thoughtful engineering.
  • Love working with LLMs and AI —you’re fascinated by what’s possible now and what’s coming next.
  • Are passionate about user experience and thrive on solving real-world challenges through AI.
  • Embrace a fast-paced, high-growth setting with an “own it and run with it” mentality.
  • Are open to SF-based collaboration (or traveling here occasionally to foster team synergy).

Bonus Points

  • You’ve shipped a production LLM or consumer app beloved by actual users.
  • Solid background in ML, recommendation systems, model-based evals, or observability .
  • Hands-on experience with Postgres, ElasticSearch, AWS, or IaaC tools .
  • Curiosity about Elixir or Go .
  • Love working with TypeScript, NextJS, Fastify , or other modern web technologies.
