Machine Learning Engineering Intern, Evals/Post-training

Winter 2026 (January - April) Internship - full-time

Hybrid (Palo Alto, CA)

Mission:

We’re a small, fast team behind OpenBench (open, reproducible LLM evals). We turn model behavior into measurable progress, then upstream it. You’ll work alongside people, not for people: low ceremony, quick feedback, lots of ownership. You won’t be siloed; you’ll jump across evals, post-training, infra, and (when useful) product/GTM.

Responsibilities & opportunities in this role:

Build and reimplement evals (accuracy, robustness, safety, latency) end-to-end.
Run tight SFT/DPO/RLHF-style loops; track deltas and ship models for customers.
Red-team models; turn quirks into metrics and provide feedback to the inference team
Own scoped projects: design → implement → document → upstream.
Write research papers on evals you build.
Pitch improvements across the company when you see them, then ship.

Ideal candidates have/are:

Founding Engineer (grinder)
- You unblock yourself, learn fast, and ship relentlessly - scrappy first, then clean and reproducible.
- Signals: productionized side projects, CI’d repos, tools other people actually use.
Researcher (loves data and pushing the frontier)
- You reason clearly about eval design, failure modes, and data quality; you run ablations and write tight analyses.
- Signals: careful experiments, thoughtful write-ups, PRs to open-source projects.
Must-haves
- Agentic, kind, gritty.
- Hands-on with evals, post-training, or applied AI (not just theory).
- Comfort getting a bit hacky while keeping results reproducible.
