• Proven experience building secure connected/IoT edge applications: networking, TLS, device identity/certificates, and resilient connectivity patterns.

• Proficiency across the full SDLC in a regulated environment: requirements, design, implementation, testing, traceability, release, and maintenance.

• Strong debugging and profiling skills on Windows; experience with CI/CD and automated testing.

• Excellent communication, collaboration, and influence skills; ability to be a key participant in architecture and design reviews.

• Ability to work in Boston and travel as required.
