Staff Software Engineer (Security and Cryptography)

Location: Remote

Key Duties and Responsibilities

• Design, develop, and integrate novel cryptographic systems into orbital edge compute platform and software products
• Architect and deliver a security and data-sovereignty model for multi-tenant workloads and communications running at the orbital edge, ensuring tenant isolation and customer control over sensitive data
• Develop cryptographic and key management solutions suited to the constraints of edge compute environments, including intermittent connectivity, limited resources, and remote/autonomous operation
• Design and implement key management and certificate lifecycle solutions, including key generation, storage, distribution, rotation, revocation, and secure deletion
• Conduct threat modeling, architecture reviews, and security code reviews for cryptography-related features
• Build libraries, APIs, and services that allow engineering teams to easily and correctly consume cryptographic services
• Partner with software and hardware engineers to deliver customer-focused solutions, balancing security best practices with time-to-market
• Integrate cryptographic solutions with hardware-backed key protection (HSMs, TPMs, or TEEs) where appropriate
• Give and receive productive feedback during collaboration and in design and code reviews
• Provide hands-on guidance and secure coding best practices to developers implementing cryptography
• Evaluate and advance cryptographic agility, including readiness for post-quantum and evolving standards
• Deliver iteratively and quickly in a fast-paced environment with significant ambiguity
• Perform additional job duties as assigned
