Research & Product Engineering Intern - AI Systems

**Research & Product Engineering Inter** n — **AI Systems** **Irvine** , **CA** · **In person** · **Paid** · **Part time during the school year or full time, with a path to a full-time offer** **The work** Small Irvine team building production AI for clinical research. You'll work directly with the CTO on three things: **Research** : take a defined question, write the hypothesis and stop rule, build the experiment, evaluate it against a public baseline, and ship what works. **Quality** : use our app and our AI system the way the team does, break them, file reproducible findings, and verify the fixes. Your findings go straight into the engineering queue. **Planning** : walk a workflow or a screen end to end, write up what's missing or wrong, and propose what we should build next. **What you bring** A strong background in computer science, statistics, applied math, biomedical informatics or a related field. Current students, recent graduates and builders with real work to show are all welcome; graduate students and anyone with a first-author paper, thesis or notable open-source work are especially welcome. **Strong Python** : clean, tested code, not notebooks that only run once. Working fluency in TypeScript or Swift, and the ability to pick up the other. **Comfortable in SQL** : joins, window functions, and knowing what a query really returns on messy data. Hands-on with LLMs and retrieval: prompting, embeddings, vector and hybrid search, judge models or fine-tuning, and the failure modes of each. **Experimental discipline** : proper splits, leakage checks, a cited baseline, confidence intervals, and a written hypothesis and stop rule before you start. Git, code review and CI are second nature; you've shipped something other people depend on. **You can read a paper on Monday afternoon and have a working prototype by Wednesday morning** . **An eye for product** : you notice when software is slow, confusing or wrong, and you can say exactly why. Nice to have: time-series or event data, speech or audio, healthcare data, or an ML systems paper. **You care about the mission: patients in better trials, evidence that saves lives.** **What you get** Direct mentorship from the CTO, your own machine and compute, and work that ships to a real production system the week it's done. Location Irvine office, in person. Please be local or able to commute.
