Responsibilities
- Product Security Evaluation
- Perform architecture and implementation reviews of embedded, cloud‑based, or mission‑critical systems.
- Analyze and validate secure boot flows, cryptographic controls, and firmware integrity mechanisms.
- Conduct threat modeling and traceability analysis against defense‑aligned frameworks (e.g., NIST SP 800‑53, NIST RMF, Common Criteria, NATO NIAG, ISO 15408).
- Evaluate usage of post‑quantum and hybrid cryptographic algorithms in secure communication and key management schemes.
- Conduct security testing of control systems, secure enclaves, radios, mission payload platforms, or ICS/SCADA endpoints.
- Defense Industry Compliance & Assurance
- Map system security evaluations to high‑assurance certification needs (e.g., FIPS 140‑3, Common Criteria EAL, DoD STIGs, DoDIN APL).
- Support technical evidence creation for compliance‑driven assurance cases and authority‑to‑operate (ATO) processes.
- Identify platform‑specific hardening strategies (e.g., RTOS, containerized defense apps, ruggedized embedded systems).
- Pre‑Sales Engineering Support
- Collaborate with business development to define secure system architectures and value propositions.
- Author technical sections of proposals, whitepapers, and compliance alignment reports.
- Translate mission objectives and operational constraints into viable secure‑by‑design implementation pathways.

- Project and Stakeholder Management
- Lead technical execution of security engagements with clear milestones, deliverables, and resourcing plans.
- Maintain ongoing communication with client technical leads and internal engineering teams.
- Ensure deliverables meet both compliance obligations and real‑world threat resilience expectations.

- Understanding of tactical system constraints and secure integration challenges in C4ISR, unmanned systems, or EW contexts.
- Exposure to Zero Trust principles in disconnected, intermittently connected, and low‑bandwidth environments (D‑DIL).
- Knowledge of authentication, authorization, identity, and secrets management technologies (e.g., OAuth2, MFA, PKI, SSO, Cloud IAM, HashiCorp Vault).
- Proficiency in applied cryptography (e.g., mTLS, E2EE, AEAD, key derivation, key wrapping, remote attestation).
- Ability to identify security vulnerabilities across platforms (e.g., OWASP Top 10, misconfigurations, transport security gaps).
