Powering Decision

Join the team redefining defense technology. From engineering systems that save lives to leading programs that change the battlefield – find your place in the future of defense.

By joining our Mission Solutions business, you will be a member of a team dedicated to providing innovative solutions that streamline the preparation and execution of intricate, mission‑critical operations. We focus on enhancing situational awareness, tactical command and control, and seamless video data exchange capabilities within a dynamic, multi‑domain environment.

Ultra Pro Logic 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.

• 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 sustainment

• 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 NSA High Assurance certification process
  , including:
  • Requirements decomposition and traceability
  • Security architecture definition and documentation
  • Development of certification artifacts and evidence
  • Participation in technical reviews and certification milestones
• Develop and maintain formal engineering documentation:
  • Software & Hardware Requirements (SHRS, IRS)
  • Interface Control Documents (ICDs)
  • Software/Hardware Design Descriptions (SHDD)
• Develop and execute unit testing, integration, and acceptance testing
  , including hardware‑in‑the‑loop and security‑relevant test cases
• Manage configuration control for software development items in certified baselines
• Collaborate closely with systems, hardware, security, and test engineers in a high‑performance, mission‑driven team
• Identify and implement process, tooling, and automation improvements to support secure development and certification efficiency
• Periodic travel (~5%) for customer interaction, test events, or off‑site integration activities

• Active U.S. Government Secret Security Clearance (U.S. citizenship required)
• Bachelor’s degree in computer science, computer engineering, software engineering, or equivalent experience
• 8+ years of embedded software development experience in C and/or Rust
• Experience with:
  • Low‑level embedded development and debugging
  • ARM‑based processors and SoC platforms
  • Firmware and hardware/software integration
• Strong understanding of memory management, concurrency, and deterministic embedded behavior

• 10+ years of embedded or firmware development experience
• Experience with Rust in constrained embedded environments (no‑st…
