About the role
<div class="content-intro"><p>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.</p>
<p>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.</p></div><p><span data-contrast="auto">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.</span><span data-ccp-props="{}">&nbsp;</span></p>
<p><span data-contrast="auto">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.</span><span data-ccp-props="{}">&nbsp;</span></p>
