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. Why experienced engineers choose Secmation * Own meaningful integration and test activities from early benchtop work through formalGovernment-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. What you'll do Independently own system integration, verification, validation, and test activities for complex defense systems. This is a highly hands-on individual-contributor role focused on technical execution, troubleshooting, test planning, verification, and customer-facing test readiness. The position does not carry formal technical team-lead responsibilities. You'll work across: * Benchtop and laboratory integration through HWIL, field testing, and formal Government-sponsored test events, including flight testing where applicable. * Translation of system requirements, technical capabilities, interfaces, and constraints into executable test plans, procedures, verification methods, and objective readiness and acceptance criteria. * Integration of complex RF, embedded, hardware, and software subsystems, including cross-disciplinary troubleshooting and root-cause analysis. * Technical coordination with Government customers, subcontractors, industry partners, program stakeholders, and internal development teams. * Identification and management of integration risks, defects, technical action items, test readiness, and issue resolution through closure. * System-level test execution, data analysis, verification evidence, detailed test reporting, and technical briefings to internal leadership and Government customers. ## Related Videos - [Are Classical Automation Frameworks Dead?
