Test Engineer III

About the role

Join Redwire's RF Systems group in Longmont, Colorado, and become an integral part of engineering the next generation of RF products. These enable mission-critical capabilities across space, air, land, and beyond. Whether it's advanced communications, sophisticated sensing, electronic warfare, or directed energy, our team delivers cutting-edge solutions — from orbital deployments to the tactical edge — in support of one force, every front.

In this role, you’ll work within a team testing hardware for space and airborne applications, with a strong emphasis on RF systems. You’ll collaborate across engineering disciplines to execute testing in a fast-paced, dynamic environment. The ideal candidate brings prior experience testing hardware in space or airborne environments. You will join a growing, interdisciplinary team and report to the Systems Integration and Test Manager.

Responsibilities

• Execute, develop and manage comprehensive test plans for high-value flight hardware, from initial concept through execution.
• Define test requirements and verification methods in close collaboration with the Systems Engineering team.
• Interface with internal and external stakeholders to negotiate test requirements and methods, co-develop plans, and provide regular updates on test progress.
• Represent Test Engineering at major program milestones and communicate test status and work in a collaborative team.
• Identify appropriate testing methods and design test fixtures to support risk mitigation, prototype development, and requirement verification.
• Plan and execute environmental testing of hardware, including functional test such as vibration testing, thermal cycling, thermal vacuum, and other qualification tests.
• Develop and enhance in-house test capabilities and collaborate with other Redwire groups to leverage existing resources across the organization.
• Work closely with cross-functional teams, including technicians, product and technical leadership, and program managers, to ensure successful test execution.
• Lead and mentor junior engineers.

Requirements

• B.S. in Mechanical, Electrical, or Aerospace Engineering; Physics; Mathematics; or other space-related discipline, with 5+ years of relevant industry experience.
• Advanced degree (Master’s or Ph.D.) in a related field may substitute for 2 years of experience.
• Experience in overseeing and processing data from environmental tests such as vibration, shock, thermal cycling and/or thermal-vacuum testing.
• Experience in assembling and/or testing hardware for space or airborne environments.
• Proficiency in writing test documentation, including test plans, procedures, and reports.
• Experience preparing and presenting stage-gate reviews (e.g., CDR, TRR) and interfacing with internal and external stakeholders.
• Hands-on experience in space, small satellites, and/or RF systems.
• Experience with test failures and working with the project team and customer to develop options.
• Familiarity with writing test documentation, such as test plans, procedures, and reports.
• Experience with preparing and leading project stage-gate meetings (such as CDR, TRR, etc.) and interfacing with customers.
• Providing leadership to a team of engineers in the development and execution of a test campaign.

Skills

• Experience using CAD to design and fabricate mechanical systems, fixtures, and mechanisms.
• Knowledge of structural and metrology test methods for characterizing hardware.
• Ability to support technical risk identification and mitigation planning.
• Comfortable recommending internal process improvements.
• Familiarity with RF testing and equipment, such as oscilloscopes, spectrum analyzers, signal generators, and vector network analyzers (a plus but not required).
• Familiarity with antenna/microwave system testing and standards such as NASA/SMC (GSFC-STD-7000A, MIL-STD-810, SMC-S-016).
• Experience and training in safe handling protocols for flight hardware, including cleanroom and ESD standards.
• Experience with test-analysis correlation, including the ability to understand, interpret, and validate analysis predictions through test methods.
• Experience with generating requirements and establishing appropriate verification criteria.
• Experience in supporting technical risk identification, mitigation planning, and mitigation execution.
• Experience leading and mentoring junior engineers.
