R&D Thermal Engineer

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
• Collaborate with highly skilled engineers across multiple technical disciplines
• Gain exposure to cutting-edge space programs and emerging technologies
• Grow professionally within a fast-growing and ambitious space company
• Be part of a culture driven by innovation ownership and technical excellence

Our Offer

• Salary Range: 40000 - 70000

• EUR 1000 per year in fringe benefits

• EUR 8 meal vouchers per working day

• Stock Option Plan
