This STFC-funded Research and Innovation Associate (RIA) position for a post-doctoral researcher represents an exciting four year opportunity to join a three-University project at the core of the Mercury Imaging X-ray Spectrometer (MIXS) team for ESA’s BepiColombo Mercury Planetary Orbiter, whose 1-2 years orbital science mission at Mercury begins in March 2027. We anticipate a starting date between 1 June and 1 October 2026 (by mutual agreement) for this role.

MIXS will map and measure ratios and abundances of more than a dozen elements across Mercury’s surface, and in conjunction with other surface-looking instruments is expected to deliver a step-change in our understanding of Mercury’s geological history. 

The successful candidate will be based at the Open University to work with David Rothery and Mahesh Anand, but will do so in close collaboration with colleagues at Space Park Leicester, particularly Emma Bunce (MIXS Principal Investigator), Adrian Martindale (MIXS Instrument Scientist), John Bridges, and two recently-recruited RIAs. There will be opportunities to become involved in laboratory experiments to help to understand the remotely-sensed (principally XRF) properties of Mercury’s surface.

About you
You will hold a PhD in planetary science or a closely related field, with particular expertise in spacecraft data analysis, geochemistry, and/or X-ray fluorescence techniques. A strong publication record, evidence of independent research capability, and experience working within collaborative research environments are essential. Proficiency in ArcPro, Python and a solid grasp of planetary geological processes, especially those relevant to Mercury, will be key to your success in this role.

Essential:

• PhD in planetary science or a closely related field.
• Solid grasp of planetary geological processes, especially those relevant to Mercury.
• The ability to present your research effectively both orally and in scientific writing.
• The ability to work both independently and as part of a diverse team, and to foster links with other teams.
• A developing track record of peer-reviewed publications in international journals.
• Time management and project planning skills.
• Ability and willingness to travel to partners’ locations.
