Hybrid | Huntsville, AL | Full-Time | 9/80 Schedule

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.

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.

What we're looking for

• U.S. citizenship and an active DoD Secret security clearance are required, 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.
