Senior Embedded Software Engineer (clearance required)
About The Position
Ultra ProLogic is seeking an Embedded Software Engineer to architect, implement, and certify high-assurance cryptographic systems used by the U.S. Department of Defense, NATO, and allied partners. The role focuses on security-critical software and firmware that must meet NSA High Assurance certification requirements, contributing to cryptographic information assurance architectures, certification artifacts, and fielded systems that protect tactical and strategic networks. The engineer will develop embedded software primarily in C and Rust for cryptographic and security-critical platforms. Work includes designing crypto and key-management systems, defining security boundaries and trusted services, modernizing legacy C software, and architecting Rust-based solutions for constrained security- and safety-critical environments. The position supports formal NSA High Assurance certification from requirements through fielding and sustainment, including traceability, security documentation, certification evidence, reviews, and milestones. The role also includes preparing formal engineering documents, testing software and hardware integrations, maintaining configuration control for certified baselines, and collaborating with systems, hardware, security, and test engineers. Periodic travel of approximately 5% may be required for customer interaction, test events, or off-site integration activities.
Requirements
- Active U.S. Government Secret Security Clearance; U.S. citizenship is required.
- Bachelor’s degree in computer science, computer engineering, software engineering, or equivalent experience.
- At least 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
- At least 8 years of embedded or firmware development experience.
- Experience with Rust in constrained embedded environments, including no-std, heapless, or hardware abstraction layers (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, and JTAG/SWD debugging.
- Experience with AMD Zynq UltraScale+ MPSoC, such as the Xilinx ZCU102/104 Evaluation Kit or similar.
- Experience working on waterfall or agile development methodology-based projects.
- Strong systems-thinking mindset and 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 security boundaries, trusted services, and separation of crypto and non-crypto functions.
- Perform trade studies and embedded architecture design, emphasizing memory-safe designs and C-to-Rust transitions.
- Support NSA High Assurance certification, including requirements decomposition and traceability, security architecture definition and documentation, certification artifacts and evidence, and technical reviews and certification milestones.
- Develop and maintain Software & Hardware Requirements (SHRS, IRS), Interface Control Documents (ICDs), and Software/Hardware Design Descriptions (SHDD).
- Develop and execute unit, 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 with systems, hardware, security, and test engineers.
- Identify and implement process, tooling, and automation improvements to support secure development and certification efficiency.
- Travel periodically, approximately 5%, for customer interaction, test events, or off-site integration activities.
Benefits
- Annual performance-related bonus.
- Competitive paid time off package and 11 company holidays.
- Early finish on Friday.
- 401(k) with company match.
- Medical, dental, and vision benefits.
- Student Loan Assistance Program.
- Voluntary benefit offerings.
