Developmental Test Engineer

At Zone 5 Technologies, we're redefining what's possible in precision weapons and unmanned aircraft systems (UAS). Our team of engineers and innovators are developing cutting-edge autonomous solutions to deliver affordable and scalable precision weapons, interceptors, and UAS.
We're building the next generation of munitions and unmanned systems for the United States and its allies. If you're driven by hard problems, energized by rapid innovation, and ready to make an impact on defense technology, you belong here.
As our programs scale, so does the need for disciplined, repeatable developmental testing. We are seeking a Developmental Test Engineer to plan and execute ground-based developmental tests that mature our designs, identify design deficiencies early, and reduce technical risk before systems enter flight test.
This role is hands-on and execution-focused, supporting component, subsystem, and system-level testing of advanced counter-UAS and missile systems for U.S. Department of Defense programs. The Developmental Test Engineer works closely with design engineering to turn test data into design improvements.
Key Responsibilities:
Develop test plans and procedures for component, subsystem, and system-level developmental testing across functional, structural, dynamic, and environmental domains.
Design and build test setups, including fixtures, harnessing, instrumentation, and data acquisition systems.
Execute tests safely and efficiently in the lab and at external test facilities.
Reduce and analyze test data; identify design deficiencies, failure modes, and performance margins.
Investigate anomalies and failures, support root cause analysis, and recommend design changes.
Partner with design and systems engineering to translate requirements and risks into executable test campaigns.
Author test reports and present findings and residual risk to engineering and program stakeholders.
Support Test Readiness Reviews (TRR) and maintain test configuration and data integrity.
Help evolve test infrastructure, tooling, instrumentation, and automation capabilities.
Qualifications:
Education: Bachelor's degree in Mechanical, Aerospace, or Electrical Engineering or a related field.
Experience: 3+ years of experience in developmental, qualification, or laboratory testing of aerospace, defense, or other high-reliability hardware.
