Thermal Hardware and Test Engineer
About The Position
As the Thermal Hardware and Test Engineer, you will be responsible for hardware design, build, and test for ground and spacecraft thermal and fluid systems. This is a hands-on role, spanning mechanical, electrical, fluid, and control disciplines with opportunities to innovate at every stage: concept, fabrication, instrumentation, and commissioning. You will be responsible for developing active and passive thermal control systems, such as heat pipes, pumped fluid loops, thermal switches, etc. as well as the supporting infrastructure for testing and data-processing. Day-to-day responsibilities will be focused in thermomechanical hardware and system sizing, CAD design, fabrication, testing, instrumentation, and troubleshooting. Successful candidates thrive on solving hard problems, adapting to dynamic requirements, and collaborating across multiple domains. You will gain significant ownership, see your contributions rapidly come to life, and help us uphold the highest standards of performance, reliability, and safety in our hardware. If expanding the capability of in-orbit manufacturing to serve life-changing products to patients sounds intriguing, this role is for you. This role is open at the Eng II level, with levels determined based on candidate experience.
Requirements
- B.S. in Mechanical Engineering, or a related discipline, with consideration given to equivalent professional experience (typically 1–3+ years)
- 3+ years of experience and knowledge applying engineering principles to thermal design, test, and fabrication in a manufacturing environment
- Proficiency in detailed thermal analysis in Thermal Desktop, SINDA/FLUINT
- Experience anchoring thermal models to test and/or flight data
- Experience in planning and executing Thermal Vacuum Chamber (TVac) testing
- Experience in MATLAB (or equivalent) for data processing and task automation
- Familiarity with thermal margins and qualification test requirements in SMC-S-016
- Excellent written and verbal communication skills with an aptitude for interdisciplinary technical communication
Nice To Haves
- Hands-on fabrication skills: basic machining, welding, or rapid prototyping.
- Experience in thermal analysis tools: Thermal Desktop, ANSYS
- Proven track record of formal project management and delivering results in a fast-paced environment.
Responsibilities
- Drive end-to-end development of thermal hardware and test infrastructure: concept, design, fabrication, integration, validation, and maintenance
- Develop active and passive thermal control systems with thermal analysis engineers for payload and vehicle thermal control
- Inform manufacturing and integration of thermal/fluid hardware onto the vehicle
- Conduct component level acceptance and qualification thermal vacuum tests
- Evaluate the impact of hardware design decisions on packaging, thermal, environmental, and loads to ensure the best system-level solution
- Architect and assemble fluid, thermal, mechanical, and electrical designs, test rigs, and fixtures that support a broad range of development activities
- Implement instrumentation and data acquisition (DAQ) solutions, integrating sensors, transducers, actuators, PLCs, and embedded controllers
- Generate documentation for procedures, schematics, reports for ground test and flight hardware
- Apply first-principles thinking to diagnose issues, resolve anomalies, and optimize equipment reliability to >99% uptime
Benefits
