Staff Software Engineer (Security and Cryptography)
$180,000–$245,000 year
HybridHouston, Texas, United States
Job Summary
Design, develop, and integrate novel cryptographic systems into orbital edge compute platforms and software products. Architect a security and data-sovereignty model for multi-tenant workloads running at the orbital edge, ensuring tenant isolation and customer control. Develop key management solutions suited to edge constraints, including intermittent connectivity and limited resources, while managing certificate lifecycles from generation to secure deletion. Conduct threat modeling, architecture reviews, and security code reviews for cryptography features. Build libraries, APIs, and services for engineering teams to consume cryptographic services, and integrate solutions with hardware-backed key protection like HSMs and TPMs. Provide hands-on guidance on secure coding best practices and evaluate cryptographic agility for evolving standards. Collaborate with hardware and software engineers to deliver customer-focused solutions in a fast-paced, ambiguous environment.
