Job description

Seeking a Staff Software Engineer, Security and Cryptography to join the team designing, developing, and integrating novel cryptographic systems. Operating in a fast-paced environment characterized by rapid iteration and significant ambiguity, the successful candidate will deliver solutions quickly and effectively while developing a comprehensive security and data-sovereignty model for workloads and communications running at the orbital edge in a multi-tenant hosted environment.

KEY DUTIES & 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

QUALIFICATIONS

Education & Experience

• Bachelor of Science in Computer Science, Computer Engineering, Cybersecurity, Mathematics, or another related technical discipline, or equivalent professional experience
• [8]+ years of professional software development experience, with strong proficiency in a systems language such as C, C++, or Rust
• Deep engineering knowledge of symmetric and asymmetric cryptography and cryptographic protocols
• Experience designing and implementing key management, PKI, and certificate lifecycle solutions
• Demonstrated experience with secure development practices, threat modeling, and security-focused code review
• Experience building secure systems in cloud and/or multi-tenant hosted environments
• Experience with git distro (such as GitLab) and CI/CD tools
• Prefer experience integrating cryptographic solutions with hardware-backed key protection (HSMs, TPMs, or TEEs)
• Prefer familiarity with security and compliance frameworks such as NIST 800-53, FIPS 140-2/3, or CMMC
• Prefer experience with post-quantum cryptography and cryptographic agility
• Track record of making things happen in ambiguous, fast-moving environments
• Uses good judgement to problem-solve proactively, positively impacting hard challenges
• Demonstrated organization skills to meet tight deadlines with high quality results
