Responsibilities
- Produce and maintain security reference architectures and patterns for platform and AI components.
- Design identity, authorization, tenant isolation, service-to-service trust, and authorization boundaries for AI agents and analyst workflows.
- Design encryption, BYOK, key custody, and key-management architectures, including migration from legacy HSM-based designs to Vault.
- Design AI guardrails covering input and output controls, tool boundaries, authorization boundaries, prompt injection, and abuse defenses.
- Lead threat modeling for high-risk systems and convert findings into prioritized design changes.
- Support external security assessments by preparing architecture evidence, participating in discovery sessions, and validating implementation against documentation.
- Improve software supply-chain integrity, provenance, image hardening, and attack-surface reduction.
- Write and review designs and prototypes, test the resulting work, mentor engineers, and contribute to enforceable security standards.
Requirements
- Solid secure software architecture experience with depth in at least two of cryptography and key management, identity and authorization, tenant isolation, and threat modeling.
- Working understanding of AI and ML security and how LLM-driven features affect identity, authorization, supply chain, and verification.
- Ability to design and review real systems and defend architectural decisions to strong engineers.
- Demonstrated ability to influence engineers without formal authority when security risk and delivery pressure conflict.
- Experience with enterprise-scale SaaS or cloud-first systems, ideally in multi-tenant environments.
- Clear written and verbal communication with engineers, leadership, and customers.
- Preferred experience with Vault, KMS/HSM, BYOK/HYOK designs, regulated environments such as FedRAMP, contributions to NIST, ISO, or OWASP, talks or published research, and offensive security.
