About the role

Security-focused role building and operating the security systems enabling Parallel to ship quickly while reducing risk, with emphasis on application security, secure defaults, AI-assisted tooling, and agentic systems that consume untrusted web content.

Responsibilities

  • Build and operate security systems for rapid, low-risk shipping across Parallel’s products.
  • Work across application security, secure defaults, AI-assisted security tooling, and the attack surface of agentic systems that consume untrusted web content.
  • Fix real vulnerabilities when they appear and modify underlying systems to reduce recurrence of similar issues.
  • Help define how security fits into the development process, including reusable authentication/authorization patterns, data handling, outbound access controls, and enterprise-facing security controls.
  • Ensure security reviews are integrated into the software development lifecycle rather than as a separate end-of-cycle process.

Qualifications

  • Significant software engineering experience, including several years focused on product or application security
  • Strong experience with web and API security, including authentication, authorization, SSRF, IDOR, injection, and multi-tenant isolation
  • Built frameworks, libraries, or secure defaults that reduced entire classes of vulnerabilities across a codebase or engineering organization
  • Experience building security tooling using current AI models (e.g., automated code review, threat modeling, triage, agent harnesses, evaluation systems)
  • Experience securing systems that process untrusted inputs, especially LLM or agentic systems
  • Ability to work independently as the primary security owner and make clear prioritization decisions
  • Strong production coding skills in Python, Go, TypeScript, or similar languages
  • Experience with GCP, Kubernetes, security research, open source security tooling, or conference talks is a plus
