Staff Software Engineer (Security and Cryptography)

Title: Staff Software Engineer

Duration: Full-Time

Location: Houston, TX (Can be remote however you must be onsite in Houston for atleast 2 weeks per month at a stretch)

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

• [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

Compensation offered will be determined by factors such as location, level, job-related knowledge, skills, and experience. Range $180K – $245K.
