The Role

You will play a key role in delivering high‑quality ecological services. You will lead surveys and contribute to a diverse range of projects across sectors including energy, defence and infrastructure. Your expertise will support clients in achieving their environmental goals while maintaining compliance with regulatory requirements. As Tetra Tech builds on its demonstrable track record as one of the leading global environmental consultancies, we are seeking Assistant/Consultant Ecologists to join our national ecology team. With ambitions to grow our UK presence to emulate the success of the global business, we are looking for candidates to join our established network of over 90 ecologists with the motivation to develop their field skills across a broad portfolio of projects, including data analysis and technical reporting.

We are looking for talented individuals who are keen to learn and are developing a set of field‑survey skills, preferably including bats and report writing skills. Those holding protected species licences or working towards them are favourable. In return, they will play an integral part the team, directly supporting our project delivery, while gaining valuable support, mentoring and training from our national experts.

You will be regularly involved with surveys and mitigation schemes for a variety of habitats and protected species including bats, reptiles, great crested newts, dormice, badgers, water voles, otters, birds and many other species. The position will involve carrying out a range of field surveys over the busy survey season, alongside office‑based work such as data analysis, report writing, survey planning, and attendance at team meetings. With a clearly defined career framework that can be adapted to suit specific aspirations, Tetra Tech is able to provide extensive and focused training including field work, shadowing, project management and report writing, to align with career aspirations. We also financially reward our team for gaining their bat handling licence from the relevant statutory authority. We are currently working on multiple sites requiring Nutrient Assessments, Biodiversity Net Gain assessments, and enhancement or management plans with the opportunity our Assistants and Consultants to be actively involved in implementing these on the ground.

The role will require work with colleagues from across the wider business on multi‑disciplinary opportunities and projects so a willingness to understand how other parts of the business work would be advantageous. Our success is, in part, due to our established and long‑lasting relationships with clients and the role will involve working closely with clients across a range of sectors including Residential, Defence, Infrastructure, Energy and Government Services.

We operate fully flexible, hybrid working which allows our ecologists to choose where, how and when they work as long as our clients are receiving the high‑quality service they expect.
