The appointment may be made at Consultant or Senior Hydrogeologist grade, depending on your experience.

• Field leadership: Carry out and supervise field activities such as groundwater monitoring, water features surveys, borehole drilling and installation, pumping tests, groundwater sampling and other hydrogeological testing.
• Analysis and reporting: Collate, quality-check, analyse and interpret groundwater, flow, water quality and site investigation data, then produce clear reports, notes, drawings and presentations.
• Digital and regulatory support: Use GIS and digital tools, and support abstraction, discharge, dewatering and other permit or licence applications.
• Client and project support: Help manage project set up, budgets, programmes, resources, subcontractors, change control and fee proposals, while supporting clients and junior colleagues. Contribute to tenders, fee proposals, bids and business development activities

Good Microsoft Word, Excel and GIS skills are important, along with strong organisation, communication and time management. A full driving licence and willingness to travel are required.

Desirable experience includes groundwater resources, dewatering, contaminant hydrogeology, geothermal, hydrogeological risk assessment, borehole supervision, pumping test analysis, MODFLOW, hydrochemistry, permit/licence applications, fee proposals, subcontractor management, and working towards chartership or UK security clearance.
