Program Dates:
- June 1 - August 21
- June 22 - September 11
About the Role:
The Thermal team at Planet is seeking a Thermal Engineer to help drive the thermal design, analysis and testing of our spacecraft and their subsystems. The ideal candidate is passionate about Planet’s mission and thrives in a people-oriented environment. This role will appeal to candidates who are looking for opportunities to help Planet take their satellite designs and production to a new level by bringing new technology to our company on our new projects. As a member of the Thermal Engineering team within Planet’s Space Systems division, you will be a contributor and stakeholder in Planet’s agile aerospace approach to spacecraft design; you will work closely with the Mechanical Engineering, Electrical Engineering, Qualification, Mission Operations and Manufacturing teams, as well as the rest of Planet’s leading-edge spacecraft design teams.
This is a full-time, hybrid role which will require you to work from our San Francisco office 3 days per week.
Impact You’ll Own:
- Own the thermal design on key payload subsystems
- Collaborate with electrical and mechanical engineers to derive requirements that drive the thermal design.
- Ensure that all components of our payload are within their operational and survival temperature ranges throughout all phases of the mission.
- Collaborate with optical and mechanical engineers to ensure optical requirements are met.
- Drive part/assembly thermal analysis on key spacecraft subsystems to meet temperature requirements.
- Oversee quality of our space hardware as it’s being built.
- Develop sub-contracts and Interface Control Documents (ICDs) for thermal hardware fabrication as needed.
- Support test planning and qualification campaigns by developing tests that validate the thermal performance of your designs.
- Support ICD development by ensuring the thermal interfaces are sufficiently well defined for mission success.
- Own thermal hardware configuration management and release to production.
- Collaborate with mission operation engineers to ensure proper mission design and flight operational and survival temperatures.
- Collaborate with the guidance, navigation and control engineers to ensure proper mission design and thermal modeling inputs.
What You Bring:
- Pursuing Master’s or PhD degree in Mechanical/Aerospace Engineering or other related engineering or science degree.
- Good understanding of heat transfer.
- Ability to design tests proving thermal design.
- Experience in Thermalanalysis or similar tools for chip-level analysis.
- Ability to progress initiatives while working independently and as part of a team.
What Makes You Stand Out:
- Experience with satellites
- Experience with CAD - drawing your own thermal parts
- Machine shop and rapid prototyping experience (e.g., 3d printing, metal fabrication)
- Knowledge of thermal control technology of spacecraft
