About the role
Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge. For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles. Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more. We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet. About the Role As the Lead Spacecraft Test Engineer, you will lead and develop a team of test engineers while driving excellence across environmental testing and spacecraft checkout operations. You'll be responsible for mentoring your team, setting technical direction, and owning the strategy and execution of test programs from early development through rate production. We're looking for motivated, detail-oriented engineers who combine deep technical expertise in environmental and functional testing with the leadership instincts to build and develop a high-performing team in a dynamic, fast-paced environment. Responsibilities Lead, mentor, and develop a team of spacecraft test engineers while managing project assignments, performance, and professional growth Own the development, execution, and continuous improvement of test plans, procedures, protocols, and requirements across environmental testing and checkouts — including vibration & shock, thermal cycling & TVAC, EMI/EMC, and pneumatic pressure testing Drive the strategy and roadmap for scaling test operations from low-rate development to high-rate production, ensuring test capacity and capability grow with the program Scope, procure, set up, and maintain environmental test equipment and infrastructure, making build-vs-buy decisions and managing capital planning for the test organization Provide hands-on technical leadership on critical test challenges, including test fixture design, instrumentation setup, and anomaly resolution Collaborate with cross-functional teams including production, design engineering, and quality assurance to identify and resolve issues and ensure test requirements are captured early in the design process Analyze test data, interpret results, and generate comprehensive test reports; establish standards for data quality and reporting across the team Ensure compliance with applicable aerospace testing standards and regulations Lead root cause and corrective action investigations for test escapes and anomalies, driving systemic fixes rather than one-off solutions Stay current with industry advancements and best practices in spacecraft environmental and functional testing Requirements U.S. Persons status is required as this position needs to access export-controlled data Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or a related field 5+ years of experience in environmental or functional testing within the aerospace industry Strong leadership fundamentals demonstrated via proven ability to delegate effectively, drive strategic initiatives from concept to execution, and foster individual growth Deep knowledge of aerospace testing standards, protocols, and regulations such as MIL-STD-461, GSFC-STD-7000, SMC-S-016, and MIL-STD-810 Proven track record of implementing test process improvements that resulted in measurable gains in quality, efficiency, schedule, or cost Demonstrated experience with operating, maintaining, and procuring environmental testing equipment Strong understanding of instrumentation used during environmental testing including thermocouples, accelerometers, and DAQs Excellent analytical skills and ability to communicate complex technical findings to cross-functional stakeholders Ability to operate effectively in fast-paced, hardware-intensive environments Preferred Requirements 1+ years of technical leadership or team management experience Strong people leadership skills including talent development, performance management, and ability to drive team accountability while maintaining morale Experience in spacecraft or launch vehicle test programs Experience scaling environmental test operations from new product introduction to rate production Familiarity with AS9100 or other high-reliability aerospace quality systems Experience with test automation, scripting, or programming in Python, LabVIEW, or similar Knowledge of data acquisition and analysis software Experience with MES/ERP systems and digital production tracking Certification in relevant aerospace testing standards #LI-HC1 Why Join Apex?
