Résumé du poste

The European Synchrotron Radiation Facility (ESRF) in Grenoble invites applications for an Experienced Researcher to strengthen the BM18 beamline's algorithmic, reconstruction and HPC capabilities.

You will develop reconstruction and image-processing methods for high-sensitivity tomography, design scalable workflows for very large datasets, and help merge new developments back into ESRF's main tomography tools, collaborating across beamline and computing teams.

Qualifications

• PhD in Physics, Applied Math, CS, Imaging Science or related field.
• Strong experience in algorithm development, scientific computing, image processing, inverse problems or related areas.
• Interest at the interface between experiments, data and computation.
• Experience in tomography, synchrotron imaging or reconstruction methods is an asset.
• Ability to collaborate with scientists and engineers from diverse backgrounds.
• Proficiency in English (working language at ESRF).

Responsabilités

• Developing and improving reconstruction and image-processing methods for advanced tomographic experiments at BM18.
• Designing and optimising scalable processing workflows for very large datasets and the corresponding HPC infrastructure.
• Contributing to the stabilisation, documentation and maintainability of reconstruction tools for routine and high-end use.
• Working closely with beamline scientists and participating in experiments to align algorithmic developments with experimental needs and user projects.
• Contributing to the transfer and adaptation of methods developed at BM18 to other ESRF tomography beamlines.

Organisation/Company European Synchrotron Radiation Facility Research Field Physics Researcher Profile Established Researcher (R3) Positions Other Positions Application Deadline 8 Oct 2026 - 23:59 (Europe/Paris) Country France Type of Contract Temporary Job Status Full-time Is the job funded through the EU Research Framework Programme? Not funded by a EU programme Reference Number 26-33-T-EXP-ADA Is the Job related to staff position within a Research Infrastructure? No

Offer Description

BM18 is a flagship ESRF beamline dedicated to high-sensitivity phase-contrast tomography of large and complex samples, combining hierarchical phase-contrast tomography and propagation phase-contrast imaging. Over recent years, BM18 has enabled advanced acquisition modes delivering exceptional results in image quality, in step with progress in reconstruction methods, algorithm development and high-performance computing (HPC).

You will reinforce the algorithmic, reconstruction and HPC component of BM18, in close collaboration with beamline scientists and ESRF computing scientists. The position builds on an already ongoing development effort, contributing additional capacity for method development, implementation and consolidation, while also spending around 25% of the time bringing developments made for BM18 back into the main ESRF tomography tools codebase for use on other beamlines.

The work will take place in the Algorithms & scientific Data Analysis (ADA) group, in close collaboration with the BM18 beamline. Further information about the post can be obtained from Vincent Favre-Nicolin ( [e-mail] ) and Alessandro Mirone ( [e-mail] ).

Your missions include:

• Developing and improving reconstruction and image-processing methods for advanced tomographic experiments at BM18.
• Designing and optimising scalable processing workflows for very large datasets and the corresponding HPC infrastructure.
• Contributing to the stabilisation, documentation and maintainability of reconstruction tools for routine and high-end use.
• Working closely with beamline scientists and participating in to experiments to align algorithmic developments with experimental needs and user projects.
• Contributing to the transfer and adaptation of methods developed at BM18 to other ESRF tomography beamlines.

Expected profile

• PhD degree or equivalent in Physics, Applied Mathematics, Computer Science, Imaging Science or a related field
• Strong experience in algorithm development, scientific computing, image processing, inverse problems or related areas
• A strong interest in working at the interface between experiments, data and computation
• Experience in tomography, synchrotron imaging or reconstruction methods is an asset, though not a strict requirement
• Capacity to learn and evolve in a demanding environment where algorithmic developments are tightly coupled to challenging experimental conditions
• Ability to work effectively as part of a team and in close interaction with scientists and engineers from different backgrounds
• A rigorous, solution-oriented and scientifically mature approach
• Proficiency in English (working language at the ESRF)

Working conditions

3-year temporary contract.

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

What makes the ESRF experience unique…

• Join an innovative international research institute, with a workforce from 38 different countries
• Collaborate with global experts to advance science and address societal challenges
• Come and live in a vibrant city, in the heart of the Alps, and Europe's Green Capital 2022
• Enjoy a workplace designed to support your quality of life
• Benefit from ourcompetitive compensation and allowancespackage, including financial support for your relocation to Grenoble
