For more than half a century, Serco has walked alongside the pioneers of space. Serco has supported over 50 ESA missions where our teams have helped launch satellites, guide spacecraft across the void and turn data into discoveries that reshape our world.
With thousands of specialists contributing across the entire space lifecycle from satellite testing to launch services, LEOP to operations and surveillance, we’ve become a trusted force in national And European space strategies. And now, the next chapter could include you.
We are looking for a highly motivated Full Stack Software Engineer to join a multidisciplinary team supporting ESA scientific missions in the fields of Astronomy, Planetary Science and Heliophysics.
The successful candidate will contribute to the design, development, integration and maintenance of software systems supporting Science Operations Centres (SOC) throughout the complete mission lifecycle, from mission development phases to routine operations.
For missions under development, the engineer will participate in the definition of software architectures, development of new services and applications, system integration activities and validation of mission-specific components. The role includes close collaboration with cross-mission teams to maximise software reuse, promote harmonisation and contribute to common frameworks and services shared across multiple ESA missions.
For operational missions, the engineer will maintain and evolve existing systems, implementing enhancements, bug fixes and corrective maintenance activities based on feedback from operators, scientists, instrument teams and mission stakeholders.
Working within Agile and DevOps environments, the engineer will contribute to the delivery of reliable, maintainable and high-quality software supporting the scientific exploitation of ESA mission data.
