Security Software Engineer

Our client is an AI company building autonomous agents for enterprise customers. Their agents handle sensitive customer data and take real actions inside business-critical software, so security sits at the center of how the product earns trust and wins larger accounts. This is a senior, hands-on individual contributor role with a direct line to engineering leadership. You will shape the security architecture for the agent platform and write much of the code that enforces it. What You'll Do

• Own the threat model and security roadmap for the agent platform
• Design and build controls that limit what agents can do, including permissions, approvals, and sandboxed execution
• Develop secure identity, credential, and data handling across services and tenants
• Harden application packaging, updates, and release processes
• Write security-focused tests, investigate vulnerabilities, and lead incident response engineering
• Partner with product engineers and support customers through security reviews

What You Bring

• Strong software engineering background: production systems you personally designed, built, and shipped
• Solid CS fundamentals: algorithms, concurrency, operating systems, and systems design
• Hands-on security engineering: authorization, secrets management, process isolation, or network security
• Comfort debugging across backend services and operating system layers
• Clear thinking on AI-specific risks such as prompt injection and untrusted model output
• Ability to prioritize and own outcomes in an ambiguous, fast-moving environment

Nice to Have

• Python, TypeScript, or Rust
• Desktop application or endpoint security experience
• Experience with AI agents, agent tooling, or developer tools
• Enterprise identity, on-prem, or restricted-network deployments

Why is This a Great Opportunity

• Tackle new, high-impact problems in AI agent security
• Set the security architecture and engineering standards for the company
• Work closely with leadership and see your decisions ship quickly
• Health Care Plan (Medical, Dental & Vision)
• Retirement Plan (401k, IRA)
• Life Insurance (Basic, Voluntary & AD&D)
• Paid Time Off (Vacation, Sick & Public Holidays)
