Job Description

Ultra ProLogic is expanding its encryption business and seeking an Embedded Software Engineer to help architect, implement, and certify high-assurance cryptographic systems used by the U.S. Department of Defense, NATO, and allied partners.

This role goes beyond traditional embedded development. You will work on security-critical software and firmware that must meet NSA High Assurance (HA) certification requirements, contributing directly to cryptographic information assurance architectures, certification artifacts, and fielded systems protecting real-world tactical and strategic networks.

If you are motivated by deep technical challenges—secure embedded design, Rust adoption in constrained environments, and building systems that withstand formal certification scrutiny—this role offers rare and meaningful work.

What You’ll Work On

• High-assurance cryptographic and key management systems supporting secure communications, remote rekey, and lifecycle management
• Embedded software and firmware operating within defined crypto, INFOSEC, and High Assurance boundaries
• Architecture and implementation of cryptographic information assurance (IA) software and systems
• Modernization of legacy C baselines and architecting Rust-based embedded solutions for security- and safety-critical environments
• Systems that undergo formal NSA High Assurance certification, from requirements through fielding and sustainmentRole Responsibilities

• Design, develop, and maintain embedded software primarily in C and Rust for cryptographic and security-critical platforms
• Architect cryptographic information assurance software and systems, including definition of security boundaries, trusted services, and separation of crypto and non-crypto functions
• Perform trade studies and embedded architecture design, with emphasis on memory-safe designs and C-to-Rust transitions
• Actively support the , including:
