You’ll lead and deliver high-profile environmental assessments, providing specialist advice across complex consenting, environmental risk and regulatory compliance challenges.

Your responsibilities will include:

  • Leading and quality assuring HRAs, including screening, Appropriate Assessments and tests of likely significance
  • Providing technical input into marine ecology assessments, Sustainability Appraisals and Marine Licences
  • Designing and overseeing marine surveys covering intertidal, subtidal, benthic, fish and marine mammal environments
  • Interpreting complex ecological datasets and producing robust technical conclusions
  • Providing specialist ecological advice around defence trials, in-water works, vessel operations and marine noise/sonar impacts
  • Advising on environmental constraints associated with SPAs, SACs, MCZs and SSSIs
  • Supporting Environmental Management Plans, operational environmental risk and protected species compliance
  • Building relationships with clients, regulators, statutory nature conservation bodies and other stakeholders
  • Preparing and presenting technical reports, briefings and presentations to technical and non-technical audiences
What I'm Looking For
  • A relevant degree in Marine Biology, Ecology, Environmental Science or a related discipline
  • Extensive experience delivering and leading HRAs for marine or coastal projects
  • Experience completing Level 2 Appropriate Assessments and complex project-level HRAs
  • Strong knowledge of marine protected areas and UK protected species and habitats legislation
  • Experience with marine noise, disturbance, water quality and habitat loss pathways
  • Proven experience preparing, reviewing and quality assuring technical reports
  • Strong stakeholder management and client-facing skills
  • Experience working with defence clients, ideally MOD, DIO, Royal Navy or defence contractors
  • CIEEM membership and/or Chartered Environmentalist status

This role would suit someone who enjoys working at the point where marine ecology, regulation, defence operations and complex environmental assessment meet.
