As ESS gets closer to it's steady-state operations phase, our Neutron Scattering Systems (NSS) Firmware Team is growing its development capability. We are now looking for a Senior Firmware Developer to help shape the future of neutron detector readout systems at the European Spallation Source.

This is a senior, hands-on technical leadership role focused on FPGA firmware architecture, implementation, integration, and long-term maintainability. You will play a key role in the development of embedded firmware readout chains for neutron detector front-end systems implemented on Xilinx FPGAs and synchronized to a high-precision common time base.

Working closely with engineers across the Detector Group, Experimental Control and Data Curation (ECDC) team, Integrated Control System (ICS) division, IT infrastructure, vendors, and international in-kind partners, you will contribute to the design and delivery of robust, scalable, and maintainable firmware solutions that support world-leading neutron science.

The role is strongly development-oriented, with an emphasis on engineering excellence, technical leadership, and practical delivery rather than administrative overhead. You will collaborate closely with the Firmware Team Lead while maintaining significant technical autonomy and influence over architecture, tooling, verification strategies, and development practices.
