Aimed at mid-level engineers with thermal analysis expertise who thrive in agile, collaborative space propulsion projects.
Derived from job-description analysis by Serendipath's career intelligence engine.
As a Propulsion Thermal Engineer at The Exploration Company, you will be at the forefront of developing thermal models and conducting detailed analyses to ensure the efficient and safe operation of Nyx's propulsion system, making this role ideal for someone with a strong background in aerospace or mechanical engineering and a passion for space exploration.
Original posting from The Exploration Company via Ashby
Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.
We want you as a talented Propulsion Thermal Engineer to support the design, analysis, and validation of thermal behavior within Nyx Earth propulsion system.
The role focuses on evaluating heat transfer phenomena associated with thruster operation, including heat soak back effects and thermal interactions between closely integrated propulsion components.
KEY RESPONSIBILITIES
In your capacity as Propulsion Thermal Engineer, your role will be continuously evolving, but day to day your duties will include:
- Thermal analysis of thruster interaction with the system
- Perform detailed thermal analyses of spacecraft thrusters during steady-state and transient phases.
- Assess and justify transient heat soak back effects following thruster shutdown, including impact on surrounding structures and components.
- Develop thermal models to predict temperature evolution in propulsion subsystem.
- Support and propose design decisions to mitigate adverse thermal interactions.
- Modeling & Simulation
- Build and correlate thermal mathematical models (Thermal Desktop, ...).
- Conduct transient and steady-state simulations.
- Perform sensitivity analyses and trade-offs.
- Verification & Validation
- Support thermal test campaigns (component and system level).
- Correlate analytical models with test data.
- Documentation & Reviews
- Produce technical reports to support design reviews (CDR, QR).
- Interface with propulsion, mechanical, and system engineering teams.
WHAT WE WOULD LOVE TO SEE FROM YOU
- Master’s degree or PhD in Aerospace Engineering, Mechanical Engineering, or related field with specialization in thermal sciences.
- Experience with propulsion system thermal justification
- Strong understanding of:
- Heat transfer (conduction, radiation, convection where applicable)
- Transient thermal behavior
- High-temperature material behavior
- Experience with thermal analysis tools (Thermal Desktop, SINDA/FLUINT).
- Programming/scripting skills (Python, MATLAB) for automation.
- Knowledge of spacecraft propulsion systems
- Familiarity with ECSS or NASA thermal standards.
- Experience in spacecraft development lifecycle.
- Cross-disciplinary collaboration
- Technical reporting and communication
