Youve planned, run, and signed off on hydrostatic or proof tests on large, complex hardware. * Strong command of pressure system design: P&IDs, relief sizing, stored energy, and codes like ASME BPVC Section VIII, B31.3, and PCC-2 * Experience specifying, installing, and commissioning test equipment and data acquisition systems (NI, Dewesoft, HBK, or similar) * Test automation in Python, LabVIEW, or similar * A record of leading test programs or cross-functional projects from start to finish * Experience making and defending tradeoffs across cost, schedule, quality, and safety with customers and internal teams, and knowing when to change course * Able to travel to other sites and support occasional nights and weekends around test events ## Description Test Engineering is a brand new team at Hadrian, built from the ground up with no legacy test framework to work around. As a Test Engineer, youll be the responsible engineer and technical lead for all proof and functional testing on a large manufacturing program for complex weldments. Youll set the test strategy for the program and decide what we test, how, and why. Youll use engineering first principles to decide which requirements we meet, exceed, or push back on, and youll make the calls on cost, schedule, quality, and safety. Youll lead the design of the test equipment, make sure every test is safe, and coordinate the engineers and technicians who build and run it. Youll be on the floor for first articles, hand each test off to production, and set the standards the team carries to the next program. The program is in its development phase today, and scope will grow as it moves into production. Many of the test capabilities will take 6 to 12 months to build, so the work you do now shapes how the factory runs later. If you like building a test program from an empty floor, leading through your expertise, and owning the outcome, this role is for you. What You'll Do * Own the test strategy and test plan for every program requirement, from customer spec to final data package * Interpret customer test specs, and negotiate changes when you disagree * Lead the selection, purchase, and integration of hydrostatic, proof, and functional test equipment into the work center. Design custom pressure systems, fixtures, and data acquisition when nothing off the shelf fits. * Own test safety: hazard analysis, stored energy calculations, and engineering controls for every test you stand up * Set the data collection, labeling, storage, and traceability requirements for program testing, and work with our controls, software, and data teams to build the tools * Write test automation, process plans, work orders, and training materials, and set the standard the rest of the team follows * Hand each test off to production with clear accept/reject criteria and trained technicians * Deliver a complete test data package to the customer showing compliance with every agreed requirement * Lead customer reviews and witness tests * Mentor engineers and technicians on pressure testing, test design, and safety * Work with build engineering, factory automation, factory planning, production, and workforce training to keep testing in step with the build. The line should never be waiting on a test result.
