About the role

Security-focused platform engineer mission to shape Applied Compute's security posture, build defenses for AI-native agent systems, and scale security across a multi-tenant platform serving enterprise customers.

Responsibilities

  • Shape the security architecture of our platform end-to-end, from data and credential handling to agent execution and customer deployments
  • Lead threat modeling and secure design reviews; identify and prioritize the risks, attack surfaces, and assumptions that matter most
  • Drive our offensive security program: continuously stress-test our platform, agents, and pipelines against the kinds of adversaries we should actually expect to face
  • Build the tooling, automation, and detections that scale security across the company — including agent-based systems that turn our AI capabilities into a defensive force multiplier
  • Partner with engineers across the company to instill secure-by-default practices and remove classes of risk through better design
  • Own the security guarantees we present to enterprise customers and their CISOs
  • Lead incident response when it matters: detection, containment, communication, and durable fixes
  • Build our security teams as we grow

Qualifications

  • 5+ years of hands-on experience in platform security and cyber defense
  • Have an exceptional eye for finding flaws others miss, and instinctively ask "how would I break this"
  • Lead with a strong grasp of offensive security, anticipating risk from an adversary's perspective rather than checking compliance boxes
  • Bring a builder's mindset — you have experience shipping secure software to production
  • Have strong judgment to identify the most important security vulnerabilities and put into practice
  • Reduce risk through secure design and simplicity; advocate for fundamentals like least privilege, defense-in-depth, and minimizing complexity
  • Are energized by ambiguity and high autonomy
