About Jarmin
Jarmin builds AI Employees for human-level roles. An AI Employee learns its responsibilities, understands your data, embeds into your systems, and becomes part of your team's day-to-day workflow. Companies hire AI ML Engineers, Account Executives, Paralegals, Financial Analysts, Compliance Analysts, and more.
Our founding team is from Meta Superintelligence Labs (Staff Engineers), Apple (Machine Learning), AWS (scaling infrastructure), Lockheed Martin (Research), and JPMorganChase, with experience building AI and ML systems and automating the complex work of researchers, data scientists, and ML engineers.
We are a Y Combinator Fall 2025 company in San Francisco.
About the role
As a Member of Technical Staff on Evals, you'll own how we measure AI Employee performance on the job.
Areas you may work in
- Evaluation systems: datasets, offline replay, scorers, and regression alerts
- Feedback loops for models and agents
- Autonomous failure analysis
- Defining what good, degraded, and failed runs look like, and alerting on them
You may be a good fit if you
- Have built evaluation or measurement systems, such as AI evals, experimentation, ranking, or search quality
- Can turn ambiguous quality questions into concrete metrics and decisions
- Have strong software engineering fundamentals and ship production systems
- Are comfortable where there are few established patterns
- Want to work in person in San Francisco
Even better
- You've shipped LLM systems to production and learned where they break
- You have strong data instincts and work well with researchers
- You contribute to open source projects
How we work
- Our core team is in person, resourceful, and building the future we want to live in.
- We give feedback early and often, so you always know where you stand and where you're headed.
