Staff Software Engineer (Security and Cryptography)

Title:

• Staff Software Engineer (Principal Level) Duration: Full-Time Location: Houston, TX (Can be remote however you must be onsite in Houston every other week) Candidate must be a U.S person due to ITAR regulations Fresh has partnered with a Space company, we are s eeking 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 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 Qualifications Education & Experience Bachelor of Science in Computer Science, Computer Engineering, Cybersecurity, Mathematics, or another related technical discipline, or equivalent professional experience 15 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 Compensation offered will be determined by factors such as location, level, job-related knowledge, skills, and experience.
