Descripción del empleo

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.

Flexible 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

Component Selection

• MLI / SLI
• radiators
• heaters
• thermistors
• thermal straps
• heat pipes
• cryocoolers
• cold blocks
• thermal interface materials
• insulation materials
• coatings
• paints

Detailed Design & Calculations

carry out design activities and thermal calculations from component level to top-level assembly.

Simulation Analysis

interpret thermo-mechanical simulations and propose modifications or new solutions accordingly.

Test Planning & Verification

prepare, support, and validate tests to verify thermal design performance.

Satellite & Mission Design

contribute to the definition and analysis of satellite missions.

Systems Engineering

support system-level integration and coordination activities.

Project Management

participate in planning, tracking, and execution of project milestones.

AIT Engineering

collaborate in Assembly, Integration, and Testing activities.

Flight Dynamics

contribute to mission analysis and flight dynamics engineering tasks.

Foundations in thermal design and analysis

Your knowledge in thermal modelling, simulations, or thermo-mechanical behaviour will help you contribute from day one and deepen your expertise as you face new engineering challenges.

Engineering background that supports growth

A degree in Aerospace, Mechanical, or related engineering fields will give you the technical base to understand spacecraft systems and evolve into more complex responsibilities.

Fluency in English

Speaking and writing English confidently will allow you to collaborate effectively in international contexts, share findings, and participate in design reviews.

Familiarity with scripting or technical programming

Familiarity with scripting or technical programming will support your modelling, calculations, and data interpretation as you grow into more advanced tasks.

If you are motivated by the challenge of building reliable thermal architectures, eager to learn across multiple space engineering disciplines, and excited to contribute to real missions that observe and protect our planet, apply now and join SATLANTIS on its mission to shape the future of space technology.
