Experience of applying the Environment Agency's Remedial Targets Methodology would be advantageous.
• Regulatory Knowledge: Familiarity with relevant UK legislation, including Part 2A of the Environmental Protection Act and Environmental Permitting Regulations, and experience applying the CL:AIRE Definition of Waste Code of Practice (DoWCoP).
• Project Delivery: Proven record of successfully delivering medium‑sized projects, including budgeting, scheduling, and team coordination.
• Education: Degree in Environmental Science, Geoscience, Engineering or a related subject (MSc or higher desired).
• Professional Qualifications: Progress towards (or attainment of) a relevant chartership (e.g., CGeol, CEnv) and/or Specialist in Land Condition (SiLC) accreditation is advantageous.
• Communication & Interpersonal Skills: Able to build rapport with clients and regulators, present complex information clearly, and work effectively in multidisciplinary teams.
• HSE Focus: Strong commitment to health, safety, and environmental excellence.
• Other: Willingness to travel to project sites across the UK and hold a valid UK driving licence.
