Intern: AI Red Teaming (Fall 2026)

ROLE OVERVIEW * You will try to break the systems we build and the models we protect, and turn what you find into something the team can act on: a reproducible attack, an evaluation that catches it, and a written account of why it works. * Expect some mix of: eliciting unsafe behaviour from aligned LLMs and multi-modal models; prompt injection and tool-use abuse against agentic systems; automating attack generation and evaluation rather than hand-crafting one-off prompts; and measuring whether guardrails hold under pressure. Where RealmLabs' interpretability work gives you access to a model's internals, use it. * We aim for a paper or public technical report out of every internship, plus attacks that stay in our evaluation suite after you leave. EXPECTED BACKGROUND: ADVERSARIAL ML AND RED TEAMING * Hands-on experience attacking or stress-testing models, from any direction: jailbreaks, prompt injection, adversarial examples, data poisoning, model extraction, or evaluating safety and moderation systems. * Able to read a paper and implement its attack. * (nice to have) Offensive security background outside ML: CTFs, vulnerability research, penetration testing. * (nice to have) Familiarity with agentic systems and their attack surface — tool calls, retrieval, memory, multi-agent orchestration. EXPECTED BACKGROUND: ML * Machine learning tools: pytorch, huggingface, transformers, datasets. * Applied deep learning and LLM experience. * Training and evaluating deep models. * (nice to have) finetuning LLMs, multi-modal LLMs. * (nice to have) Familiarity with ML[NLP,LLM,Vision] interpretability methods, sparse autoencoders, linear probes — as a way of locating failure modes, not as an end in itself. EXPECTED BACKGROUND: SOFTWARE ENGINEERING * Development environments and tools: * unix, git, basic clouds usage on AWS and/or GCP * jupyter * Programming: * python * (nice to have) “programming languages well-roundedness” * experience in statically-typed and functional languages COMPENSATION & BENEFITS * Market aligned compensation for interns in the bay area. REQUIREMENTS * Must be authorized to work in the USA or must be able to obtain CPT (Curricular Practical Training) approval from host university.
