Role Overview

We are seeking an exceptional Research Engineer to join Town Rock Energy and Heriot‑Watt University in a unique, jointly hosted appointment.

This is an exciting opportunity for a candidate with both Ph D‑level academic training and hands‑on industry experience in subsurface and reservoir engineering to contribute directly to the technical advancement of geothermal energy development specifically in Scotland, Ireland, Austria and Lithuania, and tangentially across Europe and beyond.

The post‑holder will support a portfolio of geothermal project development activities in the Geo Guard project (https://geoguard. hw. ac. uk) spanning reservoir characterisation, subsurface simulation modelling, well engineering design, and reservoir stimulation assessment.

Working across both the Town Rock Energy project delivery team and the Heriot‑Watt University research group, the role bridges rigorous academic analysis and practical engineering application.

This is a Grade 7, post‑doctoral level position on the Heriot‑Watt University pay spine, carrying a salary of approximately £40,000 per annum.

The exact spine point will reflect the candidate's experience and qualifications, with the potential for progression during the 24‑month appointment.

The role is fixed‑term and is anticipated to commence in late Summer or Autumn 2026.
