Are you a dedicated and ambitious Ecologist working at Assistant level, seeking your next role in commercial consultancy? If you’re an experienced field ecologist, confident leading site teams, and looking for a practical role taking you across the UK, we would love to hear from you!

We have multiple opportunities for Assistant Ecologists to join our growing terrestrial teams throughout the UK on a seasonal basis.

This is a great opportunity to enhance your 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 permanent positions at Thomson, enjoying our wide-reaching training and career development opportunities.

You’ll need to be available full-time until end of September 2021, have a car, full UK driving licence and be willing to travel and stay away from home regularly, often working unsociable hours. Accommodation and mileage will be paid for, and a generous subsistence allowance will be given when staying away from home. We will consider candidates from across the UK who are willing and able to travel regularly. Work will be a mixture of site, office and remote, but expect to be away from home regularly. There may be an expectation to work in the office when not resourced to site.

  • experience leading small teams on ecological fieldwork
