Job description

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'll contribute to Naval Operational Architecture (NOA), working alongside engineers and operators to deliver resilient, forward-leaning solutions in support of national defense.

About the role: PMAT is seeking an experienced Systems Engineer III to support systems engineering, architecture development, technical integration, acquisition lifecycle support, and capability delivery for complex Navy and DoW systems. This role contributes to System of Systems (SoS) requirements analysis, architecture development, software and hardware integration, cybersecurity risk tracking, technical documentation, and capability roadmap planning across RDT&E, fielded, and programmed environments. The candidate will work closely with chief engineers, program leadership, technical teams, cyber stakeholders, platform integration organizations, and operational users to ensure architectures, requirements, interfaces, risks, and technical decisions are clearly documented and aligned to mission objectives. The role requires strong technical judgment, architecture awareness, cross-functional coordination, and the ability to support engineering execution across software, hardware, network, communications, and data environments.

Responsibilities

• Support systems engineering execution across complex Navy and DoW programs by coordinating requirements, interfaces, architecture products, integration dependencies, technical risks, and engineering activities across stakeholders.
• Apply systems engineering processes to support system and System of Systems requirements, design, analysis, verification, validation, sustainment, and acquisition lifecycle activities.
• Develop, monitor, and maintain as‑is and to‑be architectures for fielded and programmed capabilities by tracking systems, projects, interfaces, dependencies, data flows, and internal and external architecture changes.
• Support enterprise architecture development by coordinating architecture data, technical artifacts, architecture repositories, and integration with current engineering workflows and program documentation.
• Provide technical input to software architecture, requirements‑driven design, test/behavior‑driven development, system specifications, hardware/software compatibility, and platform working parameters.
• Support SoS integration and capability analysis by identifying risks, coordinating technical studies, assisting with architecture reviews, supporting design sessions, and providing recommendations for system redesigns, improvements, and future capability roadmaps.
• Support cybersecurity‑informed architecture and acquisition activities by tracking cybersecurity implementation, cyber risk to mission, RMF considerations, security controls, cyber readiness, and architecture impacts across engineering, procurement, certification, and sustainment phases.
• Coordinate technical representation and integration activities with Navy platform organizations, program offices, change control boards, fleet stakeholders, and external organizations to support roadmaps, engineering changes, technical documentation, demonstrations, testing, and capability fielding.

About Us

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.

Culture and Values

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.

Whether you're an experienced engineer or just beginning your career, you'll work alongside experts who are committed to solving mission‑critical problems.

Required Skills and Experience

• Experience serving as a systems engineer or supporting systems engineering activities for complex software, hardware, network, communications, or mission systems.
• Experience supporting architecture development, technical integration, requirements analysis, or related systems engineering processes.
• Understanding of software architecture, requirements‑driven design, test‑driven development, behavior‑driven development, and system integration concepts.
• Experience tracking architectures, interfaces, dependencies, risks, requirements, technical changes, or integration activities across fielded, programmed, or developing systems.
• Ability to support System of Systems engineering activities, including requirements analysis, design coordination, integration planning, verification, validation, and sustainment support.
• Experience working with cross‑functional technical teams, program stakeholders, cyber personnel, engineering leadership, and operational users in a dynamic program environment.
• Ability to develop, review, and maintain technical documentation, engineering analysis, briefings, meeting minutes, architecture products, and decision‑support materials.
• Strong written and verbal communication skills with the ability to translate technical information for engineering, cybersecurity, operational, and program management audiences.

Preferred Skills and Experience

• Knowledge of Department of Defense Architecture Framework (DoDAF) and experience developing, reviewing, or maintaining architecture artifacts.
• Experience developing enterprise architectures, target architectures, capability roadmaps, S&T roadmaps, or forward‑looking views of Navy enterprise systems, platforms, enclaves, or capabilities.
