The role

We have multiple opportunities for Assistant Ecologists to help support our terrestrial ecology teams throughout the UK, in the busy field season, and are particularly keen to hear from those based within an hour’s commute of Guildford or Cardiff (or willing to relocate), who have GCN or bat licences or are proactively working towards gaining their licence.

This is a great opportunity to learn some practical survey and mitigation techniques in a range of species and habitats as well as gaining experience of working in a busy independent environmental consultancy. Many of our previous assistant ecologists have gone on to secure full time permanent positions with us.

You’ll need to be fully available from the start of May until the end of September, have a car, full UK driving licence and be willing to travel and stay away from home regularly. Accommodation and mileage will be paid for, and a generous subsistence allowance will be given when staying away from home. Whilst we are ideally looking for Assistants to join our Guildford and Cardiff teams, we are also interested to hear from applicants located in the Nottingham, Birmingham and London areas.

If you have an ecological background, but would prefer to be office based, we have several opportunities based at our Cardiff office, which may also be of interest, please do get in touch.

  • a degree in ecology or a related field, or suitable relevant experience
  • the right to work in the UK
