Job description

Embedded Software Engineer

Ultra ProLogic is expanding its encryption business and seeks 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. This role goes beyond traditional embedded development – it involves security‑critical software and firmware that must meet NSA High Assurance certification requirements, contributing directly to cryptographic information assurance architectures, certification artifacts, and fielded systems protecting real‑world tactical and strategic networks.

Key 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.
• Support the NSA High Assurance certification process, including requirement decomposition, security architecture definition, development of certification artifacts and evidence, and participation in technical reviews and certification milestones.
• Develop and maintain formal engineering documentation (Software & Hardware Requirements, Interface Control Documents, Software/Hardware Design Descriptions).
• 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.

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 sustainment.

Required Qualifications

• 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.

Preferred / Differentiating Experience

• 8+ years of embedded or firmware development experience.
• Experience with Rust in constrained embedded environments (no‑std, heapless, hardware abstraction layer).
• 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 UltraScale+ MPSoC; waterfall or agile development methodology projects.
• Strong systems‑thinking mindset with ability to assess technical risk and security impact; clear communicator who thrives in collaborative, technically rigorous teams.

Why Ultra ProLogic

• Work on fielded, certified cryptographic systems and research & development projects.
• Direct exposure to and participation in NSA High Assurance certification.
• Opportunity to influence system architecture, not just implementation.
• Hands‑on role in modernizing high‑assurance systems with Rust.
• Long‑term programs, stable funding, and deeply technical challenges.
• Backed by Ultra Intelligence & Communications, with the agility of a focused encryption business.

Benefits

• Annual Bonus – Performance Related.
• Competitive Paid Time Off (PTO) package plus 11 company holidays.
• Early finish on Friday.
• 401(k) with company match.
• Medical/Dental/Vision benefits.
• Student Loan Assistance Program.
• Array of voluntary benefit offerings.
