Systems Integration & Test Engineer III / IVSan Luis Obispo, CaliforniaAt Zone 5 Technologies, we're redefining what's possible in unmanned aircraft systems. Our team of engineers and innovators is developing cutting-edge autonomous solutions that push the boundaries of UAS technology - solving complex challenges that matter.We're building the future of UAS capabilities, and we're looking for exceptional talent to join us. If you're driven by hard problems, energized by rapid innovation, and ready to make an impact on next-generation flight systems, you belong here.Role SummaryAt Zone 5 Technologies, Systems Integration & Test Engineers support the development and execution of Hardware-in-the-Loop (HITL) environments, as well as the integration, bring-up, and validation of new technologies and features.This role is hands-on and execution-focused, operating within a collaborative cross-functional team to mature, integrate, test, and troubleshoot avionics, systems, and subsystems prior to production.Mid-level engineers in this role independently develop & execute integration and HITL test environments, own subsystem-level integration efforts, and play a key role in validating hardware and software prior to testing.
This position balances hands-on engineering with increasing technical ownership and responsibility.ResponsibilitiesHITL Development & OwnershipDevelop and maintain flight-representative HITL rigsIntegrate avionics, sensors, and control systems into test environmentsDevelop scripts/tools for simulation-driven testingLead feature validation and signal verification activitiesModel-Based Development (Software)Develop and maintain MATLAB/Simulink models for system validationSupport code generation and embedded integrationValidate control logic and system performanceAvionics Integration (Avionics)Design wiring harnesses and signal routing architecturesValidate communication protocols (CAN, Ethernet, UART)Perform signal integrity and timing analysisMechanical Integration (Mechanical)Design packaging solutions considering SWaP constraintsSupport thermal management and environmental validationDevelop integration hardware and mounting solutionsGround Testing & Flight SupportExecute and lead integration test proceduresIdentify, troubleshoot, and resolve integration issuesSupport flight test campaigns and on-aircraft validationQualificationsBachelor's degree in relevant engineering field3–8+ years of experience in aerospace integration/testStrong understanding of embedded systems and avionics architecturesExperience working independently in lab/test environmentsPreferredSIL / HIL experienceFlight test support experienceConfiguration management experienceUAV/autopilot integration experienceLeveling SignalsWorks independently on well-defined problemsOwns subsystems or test environmentsMentors junior engineersContributes to system-level decisionsPay RangeLevel III - $129k - $149kLevel IV - $150k - $170k$129,000 - $170,000 USDWhat's in it for you:Benefits:Competitive total compensation packageComprehensive benefit package options include medical, dental, vision, life, and more.401k with company-match4 weeks of paid time off each year12 annual company holidaysWhy Join Zone 5 Technologies?Innovative Environment: Work on cutting-edge technology that is shaping the future of defense and aerospace.Collaborative Culture: Join a team of passionate professionals dedicated to pushing the boundaries of what's possible.Career Growth: Opportunities for professional development and career advancement.
