Staff Security & Cryptography Engineer - Hybrid/Remote

Fresh Consulting; Houston (TX); Hybrid; USD 180,000 - 245,000; Full time

Job summary

Fresh Consulting partners with a Space company to seek a Staff Software Engineer (Principal level) to design and integrate novel cryptographic systems for orbital edge workloads. You will help build secure, data-sovereign architectures across multi-tenant environments and advise on cryptographic agility.

The role requires a BS in a technical field and 15+ years of software development experience in C/C++/Rust, with deep cryptography knowledge, PKI, threat modeling, and secure coding practices.

Qualifications

• Bachelor-level technical degree or equivalent professional experience.
• 15+ years of professional software development experience in systems programming.
• Deep knowledge of symmetric/asymmetric cryptography and protocols.
• Experience with key management, PKI, and certificate lifecycle.
• Secure development practices, threat modeling, and security-focused code reviews.
• Experience with cloud/multi-tenant hosted environments.
• Experience with Git-based CI/CD tooling.
• Familiarity with security/compliance frameworks (NIST 800-53, FIPS, CMMC) is preferred.
• Post-quantum cryptography familiarity and cryptographic agility is a plus.
• Track record of delivering in fast-moving, ambiguous environments.
• Strong problem-solving and organizational skills.

Responsibilities

• Design, develop, and integrate cryptographic systems for orbital edge compute platforms and software products.
• Architect and deliver a data-sovereignty model for multi-tenant workloads and communications with tenant isolation.
• Develop cryptographic and key management solutions for edge environments with intermittent connectivity and limited resources.
• Design and implement key management and certificate lifecycle solutions including generation, storage, distribution, rotation, and revocation.
• Conduct threat modeling, architecture reviews, and security-focused code reviews for cryptography features.
• Build libraries, APIs, and services enabling secure cryptographic consumption by engineers.
• Collaborate with hardware and software teams to balance security with time-to-market.
• Integrate cryptographic solutions with hardware-backed protections (HSMs/TPMs/TEEs) when appropriate.
• Provide secure coding guidance and feedback during reviews and development.
• Advance cryptographic agility and readiness for post-quantum standards.
