We are partnered with a Barcelona-based space technology company developing an affordable, recurrent, high-resolution thermal imaging constellation. Their mission is to provide a new perspective on Earth’s changing resources, enabling advanced environmental monitoring and data-driven resource management at general scale. They are now looking for a

Payload Systems Engineer

to join the team and take ownership of the design, analysis, integration, and validation of payloads across the constellation. This role sits at the centre of payload development, working closely with satellite platform, ground, operations, and user infrastructure teams to ensure high-quality imaging performance from concept through in-orbit operations.

Contribute across payload lifecycle phases, including design, analysis, integration, and testing Define and analyse payload performance budgets, with a focus on optical KPIs such as SNR, NEΔT, MTF, and radiometric accuracy Lead or contribute to geometric and radiometric calibration campaigns on-ground,



and support in-orbit performance validation to ensure data quality Work hands-on with technical calculations, analysis tools, and software development when required, ensuring code is well-tested and documented Bachelor’s or Master’s degree in Engineering or a related technical field Solid experience with optical performance analysis and geometric and radiometric calibration (on-ground and/or in-orbit) Familiarity with hardware design tools such as SolidWorks or equivalent Experience with thermal design and FEM analysis at payload or system level Exposure to manufacturing, integration, and testing of prototype or flight hardware Familiarity with AIV ground support equipment (MGSE / EGSE) and environmental testing (vibration, acoustic, shock, thermal vacuum, EMC) Working knowledge of Python for analysis or tooling Comfortable working in Linux-based environments Familiarity with agile development practices Fluent in English
