Join ORiS and help build the future of energy in space.
As a R&D Thermal Engineer, you will be responsible for the thermal design, analysis, and verification of spacecraft subsystems, ensuring optimal performance across all mission phases, from concept to in-orbit operations. This is mostly an R&D position.
You will work within a multidisciplinary team on pioneering missions, including our flagship demonstration of laser-based Wireless Power Transmission between satellites in Low Earth Orbit (LEO).
What You Will Do
Design and develop thermal control systems for spacecraft and payloads
Lead the maturation of the Thermal Control System (TCS) from TRL 4 to TRL 7, validating performance first in laboratory conditions and then in a representative environment (parabolic flight, 0g)
Perform thermal analyses (steady-state and transient) using industry-standard tools
Support thermal vacuum testing and model correlation activities
Support the integration of the TCS with the WPT satellite, working closely with the space team
Define thermal requirements and contribute to system-level trade-offs
Collaborate with mechanical, electrical, and systems engineering teams
Contribute to design reviews (SRR, PDR, CDR) and verification activities
What We Are Looking For
Degree in Aerospace, Mechanical, Energy or Physics Engineering
Proficiency with thermal analysis tools (ESATAN-TMS, Thermal Desktop, or equivalent)
Knowledge of ECSS standards and space qualification processes
Fluent English (C1/C2 mandatory)
Nice to Have
Experience with thermal vacuum test campaigns
At least 3 years of experience in spacecraft thermal engineering
Previous work on LEO satellite programs
Why ORiS
Work on innovative satellite missions and advanced space technologies
Play a key role in shaping system-level decisions that directly impact mission success
