Cyber Evaluations Engineer

Build and operate evaluations for cyber capabilities and safeguard robustness in AI models, analyze adversarial data, and develop cyber-abuse detection probes. The role requires hands-on cybersecurity experience, Python proficiency, evaluation expertise, and strong cross-functional communication.

About the job

Responsibilities

  • Design and run capability, uplift, and safety evaluations assessing cyber-relevant risk in new models.
  • Execute safeguard-robustness testing before major model launches.
  • Analyze evaluation results and communicate findings to cross-functional stakeholders.
  • Design, prototype, and tune detection probes for cyber misuse.
  • Collaborate with cyber policy partners to translate policy lines into layered abuse-detection architecture and measure precision and coverage over time.
  • Build and maintain internal tooling for running and scoring evaluations.
  • Work with policy and engineering partners to translate evaluation findings into safeguard improvements.

Requirements

  • Experience building or running evaluations, benchmarks, or test suites for software or ML systems, including delivering results on short, fixed timelines.
  • Hands-on cybersecurity experience, such as CTF participation, vulnerability research, exploit development, or security research.
  • Proficiency in Python.
  • Strong communication skills with cross-functional and policy stakeholders.
  • Bachelor's degree or equivalent combination of education, training, and experience in a relevant field.

Nice-to-haves

  • Deep offensive-security or security-research experience, including building AI security benchmarks.
  • Experience analyzing adversarial or abuse data, including jailbreaks, prompt bypasses, intrusion telemetry, or fraud telemetry.
  • Experience testing or evaluating systems with government partners onsite.
  • Experience with AI/ML evaluation frameworks.
  • Familiarity with coordinated vulnerability disclosure practices.
  • Experience testing pre-release or pre-deployment software or models under confidentiality constraints.
  • Experience authoring detection content such as Sigma, YARA, Suricata, or SIEM rules, or building ML-based abuse detection.
  • Active secret security clearance or higher, or eligibility to obtain one.

Compensation

  • Annual salary: $300,000–$405,000 USD.
