Senior Staff AI Security Lead in USA

  • Remote

Responsibilities

  • Design and build the enterprise AI platform for model gateway and routing, authentication and authorization, secrets handling, rate limiting, cost attribution, and audit logging.
  • Establish reusable patterns for agentic workflows, including tool and MCP server integration, sandboxed execution, human approval gates, and least-privilege agent credentials.
  • Connect security knowledge sources to AI systems through governed retrieval pipelines with access controls and data classification enforcement.
  • Build evaluation harnesses, regression suites, observability, and quality baselines covering output quality, latency, cost, hallucination, and drift.
  • Implement guardrails against prompt injection, model-output data exfiltration, insecure tool use, and model and dependency supply-chain risk; red-team the platform and applications.
  • Own the reference architecture, golden paths, internal documentation, and standards for security AI development.
  • Identify high-value AI use cases across detection engineering, incident response, threat intelligence, vulnerability management, GRC, and security operations.
  • Build production AI applications, define adoption and impact metrics, and lead workshops, office hours, documentation, and other enablement programs.
  • Partner with Legal, Privacy, and Compliance on acceptable-use policies, review processes, and AI risk frameworks.
  • Evaluate vendors and open models and maintain the organization's technical perspective on AI capabilities, security threats, and roadmap implications.

Requirements

  • 8+ years in security engineering, platform engineering, or a closely related technical field, including significant hands-on software development.
  • Production experience building and operating systems with large language models, including experience handling failures and iterating on deployed systems.
  • Strong software engineering fundamentals and fluency in Python or an equivalent language, including API design, distributed systems, and cloud infrastructure.
  • Deep understanding of identity and access management, secrets management, network boundaries, logging and detection, and secure software development practices.
  • Working knowledge of prompt injection, jailbreaks, model-output data leakage, insecure agent tool use, model supply-chain risk, dependency supply-chain risk, and practical mitigations.
  • Track record of driving technical change through influence, consensus-building, teaching, and delivering systems that users adopt.
  • Clear written and verbal communication for both technical and executive audiences, along with sound judgment about appropriate AI use.
  • Preferred qualifications include experience with agent frameworks, orchestration, MCP or comparable tool-use standards, LLM evaluation or observability tooling, security operations, detection engineering, incident response, retrieval systems, embeddings, vector databases, knowledge pipelines, AI governance, and open-weight model fine-tuning or evaluation.
  • Familiarity with the NIST AI Risk Management Framework, ISO/IEC 42001, or the OWASP Top 10 for LLM Applications is preferred.
  • Experience as a first or founding hire for a platform or capability that later scaled organization-wide is preferred.

Benefits

  • Onsite, hybrid, or fully remote work for the right candidate, with travel up to 10%.
  • Comprehensive medical, dental, and vision plans.
  • Matching 401(k), unlimited PTO, and paid holidays.
  • Parental and adoption leave, legal insurance, and a home technology stipend.
  • The total compensation package also includes bonus and equity; participation details are provided with an offer.
