Senior Security Engineer – Cloud & Application Security

About the role

We are building a modern security organization from the ground up at ClayAI. We are looking for senior or staff‑level security engineers who are strong software engineers first, with deep expertise in either Cloud Security or Application Security.

Key responsibilities

• Build security primitives, tooling, and automation that scale with the product and engineering org.
• Define and implement modern security workflows, including AI‑assisted vulnerability discovery, automated code review, threat detection, and remediation.
• Secure our cloud environment (IAM, network policies, container security, secrets management, misconfiguration prevention) and enforce least‑privilege access patterns.
• Lead secure design and coding practices, perform architecture and code‑level security reviews, and own the vulnerability discovery lifecycle (static/dynamic analysis, dependency checks, pen tests, bug bounties).
• Develop and deploy security agents and automated workflows that can scan codebases, propose fixes, and autonomously apply patches.

Required profile

• Strong software engineering fundamentals with a track record of shipping production systems.
• Deep expertise in either cloud security or application security, with the ability to flex into the adjacent domain.
• Ability to translate risk into concrete engineering work and ship solutions, not just advise.
• Comfort with ambiguity and building from first principles.
• Interest in leveraging modern automation and AI to scale security operations while maintaining engineering rigor.

Required skills

• AWS (IAM, Config, Security Hub)
• Terraform and infrastructure‑as‑code
• Container security and secrets management
• Static and dynamic application security testing
• Dependency checking, penetration testing, bug bounty programs
• AI models for security (e.g., Claude Mythos‑class models)
