Software Engineer III - Secret clearance required

At PMAT, we work on mission critical systems that directly support the warfighter, designing, building, and securing modern digital capabilities across cloud, data, and software environments. Our teams tackle complex, real‑world challenges where delivery matters more than theory, and innovation is driven by curiosity, collaboration, and purpose.

In this role, you will support PMW 160 by collaborating with engineers and operators to design, develop, and deliver resilient, mission‑focused solutions that enable and enhance national defense capabilities.

As a Software Engineer III, you will serve as a senior technical contributor responsible for designing, implementing, and evolving complex software solutions that enable mission‑critical naval capabilities. You will lead and mentor other engineers, shape technical approaches, and steward software quality across the full lifecycle—from requirements analysis and architecture through development, integration, test, deployment, and sustainment. Day to day, you will apply advanced software engineering principles and modern Agile/Dev Sec Ops  practices to solve challenging real‑world problems, integrate with diverse systems, and ensure solutions are performant, secure, and maintainable.

This role is ideal for a seasoned engineer who enjoys balancing hands‑on development with technical leadership and collaboration across multidisciplinary teams.

• Research, design, and develop complex computer and network software or specialized utility programs supporting mission‑critical Navy systems.
• Analyze user needs and operational requirements and develop robust software solutions, applying advanced principles and techniques of computer science, engineering, and mathematical analysis.
• Architect and implement new capabilities, and update or enhance existing software to improve performance, reliability, scalability, maintainability, and security.
• Collaborate with project management, acquisition, logistics, security, and operations stakeholders to integrate hardware and software systems and to develop and refine technical specifications and performance requirements.
• Apply and champion modern software development methodologies (e.g., Agile, Dev Ops/Dev Sec Ops ), including CI/CD, automated testing, and continuous monitoring, to accelerate delivery and improve quality.
• Maintain and evolve databases and data access layers within application areas, ensuring data integrity, performance, and alignment with mission and cybersecurity requirements.
• Lead and participate in code reviews, technical design reviews, and engineering discussions to ensure adherence to best practices, standards, and architectural guidance.
• Mentor and guide junior and mid‑level engineers, providing technical leadership, coaching, and support to grow the team’s capabilities.
• Develop and maintain high‑quality technical documentation, including architecture and design artifacts, interface specifications, and user or operator documentation.

PMAT is an innovative small business founded with a passion for developing forward‑leaning solutions from exceptional people that increase the mission's capability. We focus on designing and building impactful digital solutions that utilize modern cloud, data, and software concepts. Our passion is working on complex and progressive challenges such as edge platform computing, containerizing legacy platforms, distributed data platforms, or heterogeneous data analysis.

We recruit, retain, and foster a team motivated to pursue passions, investigate new ways of doing things, and embody an innovative and entrepreneurial spirit. We believe in being curious about every element of a problem and experiment relentlessly. We foster continuous learning in an environment that encourages positive collaboration and expands our capabilities. We tap into collective intelligence, acknowledging that the most brilliant people may not be in the room.

Above all else, we believe that delivering and demonstrating is more potent than a sheet of paper. We are passionate about mission‑centric design and delivering effective capabilities to and for the warfighter.
