Perform security assessments across software, firmware, and hardware, including application testing, code review, and adversarial analysis.

Build and integrate security into CI/CD pipelines, including automated testing, scanning, and policy enforcement.

Partner with software, hardware, and firmware teams to embed security into the development lifecycle.

Secure communications, telemetry, and OTA update mechanisms across distributed systems.

Develop security tooling to scale protection across multiple hardware platforms.

Lead and mentor engineers and drive cross-functional security initiatives.

5+ years of experience in Product Security, Application Security, or Security Engineering.

Programming skills in Python, C/C++, Rust, Go, or similar languages.

Experience securing software systems including APIs, microservices, and distributed platforms.

Experience with embedded systems, firmware, and Linux-based environments.

Familiarity with CI/CD pipelines and Dev Sec Ops  practices.

Ability to assess vulnerabilities across application, network, and hardware-software boundaries.

Familiarity with NIST or similar security frameworks.

Ability to own large initiatives independently.

Eligible to obtain a U.S. Secret clearance.

Expertise in IOT/OT penetration testing.

Experience in UAS, aerospace, robotics, or defense environments.

Knowledge of distributed systems, cloud security, and edge-to-cloud architectures.

Experience with AI/ML system security.
