About the Role

As the first dedicated security hire, you will own the security architecture, harden the platform, and build out the compliance posture for an AI-native requirements platform. You will lead the security efforts for AI and agentic workflows, ensuring the protection of sensitive systems requirements for customers in defense, aerospace, and other industries.

Responsibilities

  • Own security architecture across the platform, including threat modeling, secure design reviews, and establishing build standards.
  • Harden the full stack, covering application security, cloud infrastructure (identity, network, secrets), tenant isolation, and data protection.
  • Drive SOC 2 compliance and prepare for certifications required by defense and aerospace customers, such as export control and ITAR.
  • Secure AI and agentic systems by addressing prompt injection, data leakage through models, agent actions, and implementing guardrails.
  • Build necessary security tooling for detection, monitoring, vulnerability management, and CI/CD.
  • Establish and manage incident response processes, from detection to postmortems.
  • Collaborate with sales and product teams to navigate security reviews and build customer confidence.

Requirements

  • 8+ years of experience building production software.
  • Experience running secure services at scale in the cloud.
  • Deep experience in application and cloud security (AWS, GCP, or Azure), including identity and access, secrets management, network security, and data protection.
  • Proven experience owning security in a regulated or high-trust environment.
  • Experience implementing SOC 2.
  • Experience with export control, ITAR, or FedRAMP is a significant advantage.
  • Proficiency in threat modeling, secure architecture, and incident response.
