Rocket Lab

Rocket Lab is a vertically integrated provider of small launch services, satellites, and spacecraft components. Our mission is to open access to space to improve life on Earth. Our team is over 1,300 people strong and we’re adding to it every week. Collaboration is at our core – every idea is heard, and everyone makes a difference. Teams are nimble, decisions are made quickly, and we are action oriented.


This is a rare opportunity to play a key role in Rocket Lab’s evolution into an end-to-end space company that delivers launch, spacecraft, and on-orbit operations. The Space Systems Division is shaping Rocket Lab’s future with Photon, our brand of high-performance satellites, enabling innovative missions in low Earth orbit and beyond including missions for NASA to LEO, the Moon, and Mars and commercial customers, including leading the design and manufacture of 17 high-power telecommunication spacecraft buses for Globalstar.

Rocket Lab is also growing our spacecraft components business, anchored on the acquisition of Sinclair Interplanetary manufacturing reaction wheels and star trackers in Toronto, SolAero Technologies manufacturing solar power and primary structure solutions in Albuquerque, Planetary Systems Corporation manufacturing launch separation systems in Silver Spring, and Advanced Solutions, Inc., provider of flight and ground software as a service in Denver. Our components business is key to vertically integrating our spacecraft solutions and enabling constellations for customers.  


Based out of Rocket Lab’s global headquarters in Long Beach, the Senior Spacecraft Thermal Engineer is responsible for overseeing the thermal design, analysis, testing, and validation of Rocket Lab’s space vehicles. You’ll be expected to perform thermal modeling and data analysis while working closely with the test and design engineers to capture the vehicle’s thermal performance and provide input for design improvements.

  • Strong background in heat transfer
  • Experience with thermal systems and passive thermal management techniques
  • Familiarity using Siemens NX and Teamcenter, with emphasis on model interrogation and defeaturing for subsequent analyses
  • Demonstrated experience with Thermal Desktop
  • Experience with planning, execution, and data analysis of thermal balance tests
  • Strong communication skills, both written and verbal
  • Ability to work independently but also build strong working relationships with colleagues
  • Experience with constant conductance and variable conductance heat pipes
  • Experience working with multi-layer insulation: design, fabrication, installation, and test
  • Experience with 0-D and 1-D thermal/fluid networks
  • Familiarity with scripting languages such as Python and MATLAB
  • Familiarity with thermal engineering tools such as NX Space Systems Thermal, ANSYS, SINDA, and THERMICA
  • Knowledge of aspects of launch and on-orbit operations
  • Familiarity with orbital mechanics and attitude dynamics related to thermal analysis
