We are now looking to appoint a summer worker - Junior Software Developer to the Experiment Control and Data Collection Group (ECDC).
The ECDC Group aims to produce the right tools for scientists to carry out cutting-edge research, using all the capabilities of our next-generation neutron facility. The group is responsible for streamlining the user experience, building and supporting the complete software data acquisition chain, and supporting scientists at ESS with their control and data acquisition requirements.
As a Junior Software Developer summer worker, you will contribute to the development of advanced software solutions for experiment control and data processing in a large-scale scientific facility. You will play a key role in enhancing experiments at ODIN, including integration of the soft X-ray setup. You will work closely with scientists and engineers to build robust and maintainable software solutions.
Your main tasks will include:
Software development & system integration
Develop scientific experiment control software (e.g. NICOS, user interfaces).
Develop data acquisition and streaming solutions using Kafka and high-performance computing techniques.
Test, verify and validate software for experiment control and metadata/data readout.
Collaboration & project work
Improve systems in close collaboration with Instrument Scientists.
Work closely with the DMSC Division in Denmark, the Integrated Control Systems Division, technology groups, and external scientific partners.

Experience from large-scale research facilities (e.g. neutron sources, synchrotrons, particle accelerators).
Experience with additional programming languages such as C++, Rust, or JavaScript.
Knowledge of Agile methodologies, CI/CD workflows, and DevOps practices.
To thrive in the ECDC Group, you are driven, responsive, and proactive in identifying both problems and opportunities. We value collaboration highly and are looking for a true team player who enjoys working with people from diverse backgrounds and areas of expertise. Swedish language skills are a bonus, but the working language of ESS is English.
