Ability to sit, stand, bend, reach, climb, and move about regularly throughout the day and lift / carry up to 25 pounds. Must have manual dexterity to operate standard office equipment as well as lab equipment. Must be physically capable of operation of small tablet (GCS), manipulation of tight-tolerance technologies, use of hand tools and lab equipment. ## Description The Principal System Test Engineer will execute the roadmap for system test programs, conduct system level testing, root cause analyses, and improve on policies and procedures for the test department. The candidate will use their expertise in component level, subsystem and system level test and analysis to support multidisciplinary teams of engineers as they design and build the next generation of American sUAS. This role will support the test engineering department in developing and executing test plans across multiple engineering disciplines and products lines within PDW's product catalogue. We are looking for someone who thrives in an innovative and fast-paced environment, can tackle challenges as they arise, and is committed to delivering highly capable and reliable systems. What You'll Do * Plan, lead, and execute test activities ranging from component verification and validation to extended multi-hour flight tests * Coordinate and author engineering documentation around system validation and verification testing (both lab testing and in-flight), subsystem functional testing, component acceptance testing, and test protocols designed to validate products across their life cycle. * Translate user and system requirements into clear, traceable verification and validation strategies * Champion and facilitate test methodology implementation across multiple engineering departments and manufacturing operations. * Author and oversee test plans, procedures, reports, and protocols for lab, ground, and flight testing * Serve as the technical interface for system-level validation and verification activities * Develop testing schedule and execute test campaigns in coordination across multiple teams * Lead test readiness reviews, data analysis, and cross-functional test reviews * Conduct failure investigations and root-cause analyses using structured test and data analysis approaches * Partner with mechanical, electrical, and manufacturing teams to design test tools, fixtures, and jigs, This position operates in a mix of standard office setting, manufacturing environment, lab, sUAS flight line, and travel for diverse terrain testing. This role requires use of standard office equipment, hand tools, power tools, custom test apparatus, lab equipment, tight-tolerance high-sensitivity electrical and mechanical hardware, and may require occasional travel to various testing facilities to perform validation testing. This position will have exposure to outdoor weather conditions, noise, and non-climate-controlled environments. Will require the use of personal protective equipment (PPE) depending on the environment. This is a fast-paced work environment and requires cross departmental collaboration with independent and team-based responsibilities. Standard works hours for this position are 8am-5pm M-F with occasional overtime as operational needs demand. ## Related Videos - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Dirty Tests And How To Clean Them](https://www.wearedevelopers.com/videos/515-dirty-tests-and-how-to-clean-them) - [10M Data Records Lost, Underwater Computing, and Psychedelic Fish - Matthias Geniar](https://www.wearedevelopers.com/videos/1908-10m-data-records-lost-underwater-computing-and-psychedelic-fish-matthias-geniar) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Develop on Windows, Deploy on Red Hat Enterprise Linux](https://www.wearedevelopers.com/videos/1600-develop-on-windows-deploy-on-red-hat-enterprise-linux) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs)
