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
• 5+ 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

• 8+ years of embedded or firmware development experience
• Experience with Rust in constrained embedded environments (no-std, heapless, hardware abstraction layer (HAL))
• Direct experience with NSA High Assurance certification
  , RMF, or similar DoD security frameworks
• Familiarity with cryptographic system design, key management, and secure boot/trust architectures
• Experience with:
  • openOCD, gdb, JTAG/SWD debugging
  • AMD Zynq Ultra Scale+ MPSoC (e.g.,…
