About The Position

This isn't another defense contractor job. Join a mission-focused engineering team integrating and testing complex RF-, embedded-, hardware-, and software-intensive systems for national defense. This senior-level individual-contributor role is centered on hands-on system integration, verification, validation, and test execution from benchtop and laboratory environments through HWIL, field testing, and formal Government-sponsored test events, including flight testing where applicable. Own meaningful integration and test activities from early benchtop work through formal Government-sponsored test events. Work directly with complex RF, embedded, hardware, and software systems in laboratory, HWIL, field, and flight-test environments. Collaborate directly with Government customers, subcontractors, industry partners, and internal development teams. Solve cross-disciplinary integration problems and drive defects, risks, and test-readiness issues to closure. Work within a small, highly technical team where individual engineers have visible impact. Help transition defense technology from development into validated, operational capability.

Requirements

U.S. citizenship and an active DoD Secret security clearance, with the ability to obtain and maintain TS/SCI.
Bachelor's degree in Systems Engineering, Electrical Engineering, Computer Engineering, or a related technical discipline.
8+ years of progressive experience in systems integration, verification, validation, test engineering, or related systems engineering roles supporting complex hardware- and software-intensive systems within defense or national security programs.
Demonstrated ability to independently own integration and test activities from benchtop and laboratory integration through HWIL, field testing, and formal Government-sponsored test events.
Strong background integrating and testing RF, embedded, hardware, and software systems, including troubleshooting complex cross-disciplinary interfaces and system-level failures.
Experience applying Model-Based Systems Engineering (MBSE) tools and methodologies to support system definition, interface management, verification, or test activities.
Proven experience planning, coordinating, and executing verification and validation activities, including laboratory, HWIL, field, and flight-test environments where applicable.
Experience translating system requirements, technical capabilities, interfaces, and constraints into executable test plans, procedures, verification methods, traceability, acceptance criteria, and detailed test reports.
Experience identifying integration risks, managing defects and technical action items, performing root-cause analysis, and driving test readiness and issue resolution to closure.
Strong coordination and communication skills, with experience managing technical interfaces across Government customers, subcontractors, industry partners, and internal development teams, and preparing technical briefings, reports, and customer presentations.

Responsibilities

Independently own system integration, verification, validation, and test activities for complex defense systems.
Translate system requirements, technical capabilities, interfaces, and constraints into executable test plans, procedures, verification methods, and objective readiness and acceptance criteria.
Integrate complex RF, embedded, hardware, and software subsystems, including cross-disciplinary troubleshooting and root-cause analysis.
Provide technical coordination with Government customers, subcontractors, industry partners, program stakeholders, and internal development teams.
Identify and manage integration risks, defects, technical action items, test readiness, and issue resolution through closure.
Execute system-level tests, analyze data, provide verification evidence, prepare detailed test reports, and deliver technical briefings to internal leadership and Government customers.
