Fresh has partnered with a space cpmpany.

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
