Senior Security Engineer – Detection & PKI

5+ years in security engineering with demonstrated independent project ownership (not queue-based SOC analyst experience), including hands-on PKI engineering

• Self-directed detection engineering & investigation — Microsoft Sentinel, KQL/query and rule authoring, dashboards, and end-to-end security event investigation, driven independently with strong written documentation (not queue/triage-based SOC work).
• PKI engineering (not just certificate consumption) — demonstrable understanding of PKI solution design and operations: enrollment protocols (SCEP, EST), Certificate Policy / Certification Practice Statement (CP/CPS), trusted roles, Levels of Assurance, NIST SP 800-63, and real use cases such as certificate-based authentication and software signing/validation.
• Remediation lifecycle engineering — owning remediation-plan review and vulnerability/finding tracking from finding to validated closure.

Nice to Have Skills and Experience (preferred but not required):

Hands-on AI/agentic security tooling (e.g., Claude / LLM-assisted code & configuration analysis, prompt engineering for security use cases) per CISO AI direction; Absolute endpoint platform engineering (SSO, policy groups, API); scripting/automation (Python/PowerShell); aviation / OT / cyber-physical or embedded-systems exposure; HSM / key-management and code-signing infrastructure; aviation security.
