Test engineer, sr.

About the Opportunity

SigmaCorps Solutions is seeking a Senior Test Engineer to support USMC Ground-Based Air Defense fixed-site efforts under the GBAD Engineering and Logistics (E&L) program. This is a backfill of an established CLIN 005 billet on the Fixed Site task order, not a newly created position — the work, the customer relationships, and the test cadence are already in motion.

Test Engineers actively participate in program meetings to stay current on program activities and system capabilities. The role conducts thorough examinations of Marine Air Defense Integrated System (MADIS) Family of Systems engineering and test documentation, supports future test planning and events, develops test procedures, operates the system under test, provides post-test data analysis support, and aids in the creation and review of test plans and reports. The position directly supports the C2/C4 IPT and C2 test procedure development, execution, test design, and analysis.

What You'll Do

• Actively participate in working groups supporting analysis, metrics, and requirements development.
• Develop test architectures, test procedures, and test briefs.
• Contribute to Data Management and Collection Plans and analysis reports.
• Perform on-site data collection, reduction, and analysis.
• Manage the Data Availability & Traceability Matrix.
• Coordinate test schedules between the program, ranges, agencies, and support teams.
• Analyze system requirements and recommend test methods and test approach.
• Review all test reports from internal and external agencies; identify trends, deficiencies, and improvements.
• Support the development of daily test and status reports.
• Identify test and evaluation (T&E) associated risks and provide input for risk resolution and mitigation.

What We're Looking For

Required

• Five or more years of experience in the specific field plus a bachelor’s degree, or 10+ years of direct and applicable work experience.
• Previous direct experience testing, evaluating, and operating and/or maintaining aviation or ground command and control (C2), weapons, or information exchange systems.
• Proficiency with the Microsoft Office Suite (Word, Excel, PowerPoint, Outlook).
• Active Secret security clearance, with the ability to obtain and maintain a Top Secret clearance.

Preferred

• Master’s degree in a relevant field.
• Prior experience with the Marine Air Defense Integrated System (MADIS) Family of Systems.
• Experience supporting fixed-site air defense or Counter-UAS fielding and test activities.
• Familiarity with Data Availability & Traceability Matrix management and DoD test documentation practice.
