Also requires 10+ years of job-related experience, or a Master's degree plus 8 years of job-related experience. Agile experience preferred.\nCLEARANCE REQUIREMENTS: Department of Defense TS/SCI with Polygraph security clearance is required at time of hire. Applicants selected will be subject to a U.S. Government security investigation and must meet eligibility requirements for access to classified information. Due to the nature of work performed within our facilities, U.S. citizenship is required.\nDirect experience across the lifecycle of system design, integration, test, verification, deployment, and sustainment.\nBroad technical fluency across electrical engineering, electro-optics, embedded/software systems, mechanical or packaging interfaces, and test engineering, with direct experience in electro-optical or optical communications systems, cameras, lasers, fiber-optic systems, modems, or closely related systems.\nExperience defining and managing requirements, traceability, interfaces, technical baselines, and verification evidence, and developing or using MBSE/digital-engineering artifacts, including Cameo/MagicDraw concepts, SysML models, or equivalent tools.\nDemonstrated ability to lead integration and troubleshooting across hardware, software, firmware, optical equipment, and test systems while coordinating multiple programs and engineering disciplines.\nStrong technical writing, customer engagement, and briefing skills for engineering teams, program management, senior leadership, and customers.\nDemonstrated initiative in identifying material risks, asking the questions that expose them, and taking ownership of resolution.\nDemonstrated ability to distinguish technical symptoms from root causes and drive cross-functional issues to evidence-based resolution.\nResponsibilities for this Position\nROLE AND POSITION OBJECTIVES:\nWe are seeking a Principal Systems Engineer to lead the technical definition, architecture, integration, verification, and sustainment of Free-Space Optical (FSO) communications systems and associated modem, test, and support equipment. This is a classical DoD/NASA Systems Engineering role, not an IT role.\nThe successful candidate will be a hands-on technical leader with sufficient breadth across electrical, electro-optical, software, hardware, and operational domains to augment or assume responsibility for a technical lead overseeing multiple engineering IPTs and programs.\nWhat You Will Do\nLead the systems-engineering lifecycle from customer engagement and concept development before development of the Performance Work Specification (PWS) through requirements, architecture, design, integration, verification, deployment, and sustainment.\nElicit customer and user needs; distinguish operational needs from proposed solutions; and convert those needs into measurable, verifiable requirements with appropriate rationale, interfaces, acceptance criteria, and verification methods.\nDevelop and maintain system architectures, operational concepts, requirements hierarchies, interfaces, technical baselines, verification strategies, and evidence.\nLead technical integration of FSO communications systems involving cameras, lasers, optical paths, fiber-optic communications, modems, FPGAs, embedded software, GUIs, precision analog, power, networking, and automated test equipment.\nApply digital-engineering and MBSE practices, including Cameo/MagicDraw and SysML concepts, to model the decisions, interfaces, behavior, risks, and traceability that need engineering control.\nManage electrical, optical, mechanical, FPGA/firmware, software, test, customer, and supplier interfaces across airborne, land, sea, subsea, and space contexts, including the resulting environmental, operational, maintainability, integration, and verification implications.\nPlan and lead subsystem and system integration, qualification, verification, fielding, troubleshooting, and sustainment; identify and resolve design gaps, interface risks, unclear requirements, verification deficiencies, schedule threats, and programmatic dependencies.\nLead technical, design, customer, and management reviews; brief technical status, decisions, risks, and recommendations at the level of detail appropriate to the audience.\nSupport proposals, technical volumes, basis-of-estimate development, technical risk assessments, and customer technical exchanges.\nMentor engineers, develop technical leaders, delegate responsibility intentionally, and distribute critical program knowledge across the team.\nRequired Qualifications\nMaster's degree in Systems Engineering, or an equivalent combination of education and relevant experience that demonstrates the technical breadth expected to lead complex hardware/software systems, with 8+ years of progressively responsible systems-engineering experience.\nDirect experience across the lifecycle of system design, integration, test, verification, deployment, and sustainment.\nBroad technical fluency across electrical engineering, electro-optics, embedded/software systems, mechanical or packaging interfaces, and test engineering, with direct experience in electro-optical or optical communications systems, cameras, lasers, fiber-optic systems, modems, or closely related systems.\nExperience defining and managing requirements, traceability, interfaces, technical baselines, and verification evidence, and developing or using MBSE/digital-engineering artifacts, including Cameo/MagicDraw concepts, SysML models, or equivalent tools.\nDemonstrated ability to lead integration and troubleshooting across hardware, software, firmware, optical equipment, and test systems while coordinating multiple programs and engineering disciplines.\nStrong technical writing, customer engagement, and briefing skills for engineering teams, program management, senior leadership, and customers.\nDemonstrated initiative in identifying material risks, asking the questions that expose them, and taking ownership of resolution.\nDemonstrated ability to distinguish technical symptoms from root causes and drive cross-functional issues to evidence-based resolution.\nIdeal Candidate\nHas the hands-on credibility to challenge a schematic, software architecture, FPGA interface, test plan, optical alignment approach, or requirements allocation when evidence warrants it.\nTranslates customer mission discussions into executable system architectures without prematurely prescribing implementation.\nTreats integration and verification as early design activities and uses MBSE pragmatically to improve communication, traceability, and decision quality rather than merely producing models.\nCommunicates the mission impact, decision, risk, and recommended action clearly to leadership and customers, with technical depth available when needed.\nProactively identifies cross-program opportunities, staffing needs, technical dependencies, and developing risks; builds capable teams by mentoring, delegating, documenting decisions, and sharing context openly.\nIs personable, forward-leaning, technically rigorous, and comfortable engaging customers before the PWS is written.\nPreferred Qualifications\nExperience with FSO communications, optical networking, satellite or space payloads, airborne systems, maritime/subsea systems, or multi-domain mission systems.\nExperience with mixed-signal electronics, FPGA-based systems, embedded software, modem development, or automated test equipment.\nExperience using Cameo/MagicDraw, DOORS, or comparable requirements and digital-engineering tools; leading formal systems, design, and test-readiness reviews; supporting DoD, NASA, aerospace, defense, or other mission-critical development programs; or serving as a systems-engineering IPT lead, chief engineer delegate, deputy engineering manager, or comparable cross-functional technical leader.\nOur Commitment to You:\nAn exciting career path with opportunities for continuous learning and development.\nResearch oriented work, alongside award winning teams developing practical solutions for our nation’s security\nFlexible schedules with every other Friday off work, if desired (9/80 schedule)\nCompetitive benefits, including 401k matching, flex time off, paid parental leave, healthcare benefits, health & wellness programs, employee resource and social groups, and more\nSee more at gdmissionsystems.com/careers/why-work-for-us/benefits\nWorkplace Options: This position is fully on-site with Hybrid/Flex available.While on-site, you will be a part of theAnnapolis Junction Team.\nSalary Note\nThis estimate represents the typical salary range for this position based on experience and other factors (geographic location, etc.).
