JOB-1852
A very young startup building software for online merchants needs one of its first engineers to take charge of the AI portion of what the company sells. The job is hands-on production work for paying customers rather than research, and early architectural calls will shape the company for years.
Scope
- Run complete AI systems from prompting and retrieval through tool use, agent orchestration and selective fine-tuning
- Create evaluation tooling ahead of each feature so model changes are measured before they reach customers
- Bring latency and spend down to levels that hold up under real merchant volume
- Examine fuzzy product problems and judge whether the root cause lies in the model, the data or the interface
- Release to production every week and watch how changes behave in the real world
Ideal background
- Two to four years building production LLM systems, with an AI/ML product already in the hands of real users
- Strong hands-on Python for AI services; the stack also includes TypeScript, React and Node
- Experience building evaluation systems that caught regressions
- Time at a fast-growing, venture-backed startup or a company known for a rigorous engineering bar
- Computer science degree
- Nice to have: commerce or marketplace exposure, fine-tuning experience, public open-source work
On-site in the San Francisco Bay Area. Visa sponsorship is not available.
