At SATLANTIS, we develop advanced optical and space technologies with one purpose: solving global challenges from above. From our headquarters in Leioa (Bizkaia, Spain), we lead innovation in high-resolution Earth observation, satellite missions, and cutting-edge space systems.
We are now offering the opportunity to join our Space Systems department as a Space Thermal & System Engineer, where you will contribute to the design, analysis, and verification of thermal architectures that ensure the performance, reliability, and mission success of our optical payloads and satellites.

What’s in it for you
Mission-driven engineering: You will contribute directly to the thermal design, performance, and reliability of systems that operate in real space missions, supporting Earth observation, strategic applications, and scientific exploration.
Challenging, diverse projects: You will work on thermal design, simulations, satellite-level systems engineering, AIT, and mission-related activities, gaining hands-on experience across the full lifecycle of space systems.
Versátil working hours:



Private health insurance: You will have access to comprehensive medical coverage that supports your wellbeing.
As a Space Thermal & System Engineer, your purpose will be to design and validate the thermal architecture that ensures our payloads and satellites operate reliably across all mission phases. Your work will be essential to guaranteeing system performance, supporting spacecraft design, and enabling the success of multiple ongoing and future missions.
You will also contribute to system-level engineering, satellite design, AIT activities, operational planning, and flight dynamics, gaining exposure to the full space engineering cycle.

Thermal Architecture Design: define specific components, establish thermal budgets, select passive/active thermal control systems, and perform preliminary calculations.
Component Selection: choose elements such as MLI/SLI, radiators, heaters, thermistors, th
