ESRF - European Synchrotron Radiation Facility

Grenoble, France


The European Synchrotron, the ESRF, is an international research centre based in Grenoble, France.

Through its innovative engineering, pioneering scientific vision and a strong commitment from its 700 staff members, the ESRF is recognised as one of the top research facilities worldwide. Its particle accelerator produces intense X-ray beams that are used by thousands of scientists each year for experiments in diverse fields such as biology, medicine, environmental sciences, cultural heritage, materials science, and physics.

Supported by 21 countries, the ESRF is an equal opportunity employer and encourages diversity.


The ESRF's ambitious upgrade programme ESRF-EBS has replaced the old X-ray source with a new, first-of-its-kind storage ring, which is enabling ground-breaking science. As part of the programme, a new experiment control system was developed with an object-oriented and plug-in based scanning and sequencing engine written in Python and using Tango as the high-level distributed system.

The new experiment control system is today in operation on more than 35 beamlines with an increasing number of high-speed data acquisition systems which require online data reduction or online data analysis.

As part of a team of 18 software engineers who constitute the Beamline Control Unit (BCU), you will contribute to these developments. You will be responsible for the planning, implementation and commissioning of the core beamline control system. The development of new control system features required and the development and installation of challenging data acquisition systems will also be part of the work.

The BCU is responsible for the control system of all beamlines at the ESRF. As a member, you will also participate in the help-desk and standby service for scientific experiments.

Your missions will be the following:

  • Develop, document and provide support for the BLISS control system;
  • Ensure packaging and distribution of BLISS;
  • Prioritise development tasks with the beamline scientists;
  • Develop new high-speed data acquisition tools in BLISS and the necessary on-line data analysis features, in collaboration with other BCU members and other development teams;
  • Coordinate the data definitions for all online and offline data produced by BLISS (Data Policy, Data Catalogue filling, Meta Data writing and data structure for online data analysis);
  • Coordinate external collaborations involving BLISS.


  • Higher university degree (Master or equivalent diploma worth at least 300 ECTS) in Software engineering or related discipline;
  • At least 5 years of professional experience in software development;
  • Excellent skills in Python programming, object-oriented software architecture and quality assurance;
  • Experience in the field of distributed control systems and software design;
  • A genuine interest in the development of generic software tools and the ability to synthesize requirements from the requests of a large number of users are required;
  • As a member of a support team, a service oriented attitude is a must;
  • Curiosity and good communication skills are required, so that you may interact with people of different domains such as physicists, electronics and software engineers;
  • Proficiency in English (working language at the ESRF).


Permanent contract.

The salary will be calculated on the basis of relevant qualifications and professional experience.
