Senior Test Engineer

Senior Test Engineer Hadrian - Manufacturing the Future Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts. We’re accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts. Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond The Role: As a Senior Test Engineer, you will plan and execute a wide range of test activities across mechanical, electrical, and integrated systems throughout the product lifecycle. This role supports development, qualification, and production efforts and involves hands-on work with hardware, instrumentation, and test automation. You will collaborate closely with design, manufacturing, quality, and operations teams to ensure systems are robust, reliable, and production-ready. This is a collaborative, execution-focused role for engineers who value rigorous testing as a core contributor to system performance, scalability, and quality. Your responsibilities will include, but are not limited to, the following: - Plan, execute, and analyze development, qualification, and production tests for hardware systems and subsystems - Design, build, and maintain test fixtures, ground support equipment, and instrumentation for bench-level and system-level testing - Develop and maintain test plans, procedures, acceptance criteria, and test reports aligned with program requirements - Execute functional, environmental, performance, and acceptance testing, including troubleshooting and root cause analysis - Partner with cross-functional teams to translate test results into design, process, and quality improvements What We’re Looking For: - Demonstrated experience in test engineering, development testing, integration and test, or manufacturing test roles - Hands-on experience testing complex hardware systems in high-reliability environments - Experience designing and executing tests across multiple technical domains (e.g., mechanical, electrical, thermal, or integrated systems) - Familiarity with test instrumentation, data acquisition systems, sensors, and laboratory equipment - Ability to produce clear test documentation and communicate technical results effectively What will set you apart: - Experience supporting both early development and production test environments - Background working closely with manufacturing or operations teams - Experience using test data to drive continuous improvement and design iteration - Exposure to test automation, infrastructure scaling, or data quality initiatives Compensation: For this role, the target salary range is $150,000-$250,000 (actual range may vary based on experience). This is the lowest-to-highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting.
