About The Position

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/DevSecOps 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.
