Mission Solutions

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 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. 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

Role 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

Due to the nature of the programs we deliver for our customers, candidates may need to obtain the relevant security clearance or handle export-controlled material as defined by the role's requirements.
