About The Position

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.

Requirements

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
Experience with ARM-based processors and SoC platforms
Experience with Firmware and hardware/software integration
Strong understanding of memory management, concurrency, and deterministic embedded behavior

Nice To Haves

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
Experience with AMD Zynq UltraScale+ MPSoC (e.g., Xilinx ZCU102/104 Evaluation Kit or similar)
Experience working in waterfall or agile development methodology-based projects
Strong systems-thinking mindset with the ability to assess technical risk and security impact
Clear communicator who thrives in collaborative, technically rigorous teams

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 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
