  • Using and promoting integrated solutions and innovative technology, while ensuring quality is maintained and helping us to build a lasting and sustainable environmental business.

  • A degree in Ecology (or directly related subject).

  • Knowledge, understanding and experience of applying relevant guidance for surveys.

  • Report writing experience.

  • Knowledge of assessing and implementing biodiversity net gain.

  • A valid driving licence and willingness to travel to sites across your operational region
