The ideal candidate brings a strong foundation in systems engineering, practical domain experience, and the ability to lead technical work across cross-functional teams in a fast-paced environment.\nThis role requires hands-on experience in systems and system-level engineering activities, including requirements development, architecture definition, interface management, integration, verification, and technical analysis. Preferred candidates will also have direct experience applying Model Based Systems Engineering (MBSE) using SysML v1.6 or later, with Cameo Systems Modeler experience strongly desired.\nEssential Functions:\nPerform system engineering activities for capabilities across requirements, architecture, integration, verification, and technical baseline management.\nWork closely with customers and cross-functional engineering teams to design, develop, integrate, validate, and sustain new system functionality.\nDevelop and manage system-level requirements, interface definitions, ICDs, and support technical artifacts with clear traceability to customer needs and internal standards.\nConduct trade studies, technical analyses, and performance assessments to support system design decisions and risk reduction.\nSupport development and maintenance of system and MBSE artifacts that improve architecture definition, interface management, verification planning, and technical documentation.\nPlan and execute integration and test activities across laboratory, ground, and flight environments, including anomaly resolution and corrective action verification.\nDevelop test plans and procedures for specialized equipment, including anechoic chambers, spectrum analyzers, and network analyzers.\nContribute to IRAD, technical planning, schedules, and formal design reviews, including SRR, PDR, CDR, and TRR.\nProvide technical leadership through mentoring, cross-functional coordination, risk identification, and regular status communication to management and customers.\nActive Secret clearance at time of hire with the ability to obtain a TS/SCI clearance.\nAbility to travel up to 10 percent.\nPerform other duties as assigned.\nQualifications:\nBachelor’s degree in engineering (Systems, Electrical, Computer, Aerospace, Physics, or a related STEM field), and 6 or more years of relevant experience.\nGraduate degree and a minimum of 4 years of prior related experience.\nIn lieu of a degree, a minimum of 10 years of prior related Systems Engineering experience.\nDemonstrated systems engineering background across requirements development, architecture definition, interface management, integration, verification, technical reviews, and lifecycle execution.\nExperience developing technical artifacts such as system specifications, interface definitions, ICDs, verification plans, test procedures, and test cases.\nDemonstrated ability to lead technical work, coordinate across engineering disciplines, mentor junior engineers, and communicate effectively with customers and management.\nDemonstrated knowledge of laboratory, ground, and flight integration and test activities, including data analysis, discrepancy resolution, and corrective action closure.\nPreferred Additional Skills:\nDirect experience supporting ELINT programs, payloads, subsystems, mission systems, or closely related RF or signal intelligence environments.\nActive TS/SCI clearance.\nStrong ELINT domain experience supporting collection, processing, analysis, integration, test, or sustainment of electronic intelligence systems.\nExperience serving as a technical lead, integrated product team lead, or lead systems engineer for cross-functional development and test efforts.\nHands-on experience with MBSE tools and model-based engineering workflows using SysML v1.6 or later.\nExperience developing and maintaining specific SysML model content, including requirements models, structural model elements, and behavioral model elements.\nExperience using Cameo Systems Modeler to build and maintain requirements traceability, block definition and internal block views, interfaces, activities, sequences, states, and verification relationships.\nExperience applying MBSE to support architecture development, decomposition, interface management, technical reviews, and end-to-end traceability from requirements through verification.\nFamiliarity with digital engineering practices, reusable model libraries, and model-informed review products.\nExperience with simulation toolkit capabilities in Cameo or comparable MBSE environments is a bonus.","description_format":"text","description_chars":4881,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["C4ISR","Electronic
