## Job description
- Design, build and ship safeguards in the agent harness for prompt injection, single and multi-turn jailbreaks, toxicity and sensitive topics, and sensitive data exposure
- Build evals that measure safeguard efficacy on both false and true positives, using datasets from customer reports, adversarial testing and production traffic

- Select, integrate and fine-tune detection models within a stack shared by our commercial and government environments
- Balance quality, latency and cost for controls that run in the request path
- Build configurable safeguard policies so customers can decide how sensitive topics are handled
- Monitor safeguard behavior in production and fix regressions

## Qualifications
- Typically 8 or more years building production software, including 3 or more years of applied ML (training, evaluating and deploying models in production systems)
- Hands-on experience developing safeguards for LLMs, such as guardrail models, content classifiers, prompt injection or jailbreak detection, or safety evals
- Strong model evaluation fundamentals for agent trajectories and text classification, and attention to the quality of training and evaluation data
- Working knowledge of how LLM safeguards get bypassed, including indirect prompt injection through tools and documents, and multi-turn jailbreaks
- Excellent Python Experience
