We don’t want Tetra Tech to be just your next role, we want it to be a step-change in your career and ultimately a move that you are proud to have made. 

The Role: 

As Tetra Tech builds on its demonstrable track record as one of the leading global environmental consultancies, we are seeking a talented Senior Ecologist to join our southern team. With ambitions to grow our UK presence to emulate the success of the global business, we are looking for an experienced ecologist to join our established network of over 95 ecologists with the energy to contribute to a diverse project portfolio.

The person in this role will be a confident and competent ecologist and we will encourage professional development in areas that align with their own interests and Tetra Tech’s business strategy. We encourage our ecologists to lead on projects that align with their technical skillset and expertise and will provide inhouse Project Management training and an array of technical training. With an eye for detail and a desire to deliver to high standards, a key element of this role will be to provide support and feedback to colleagues on project deliverables, drawing on the knowledge of our technical experts to develop the best solutions.

We pride ourselves on our ability to offer professional ecology advice across a breadth of sectors including residential, defence, energy, government services and transport. With over 95 permanent ecologists, we can draw on the knowledge of our technical experts to develop the best solutions. Examples of projects we currently work on include:

·Bat roost assessment and emergence surveys of Service Family Accommodation

·Ecological appraisals and Protected species surveys including badger, great crested newt, reptile, dormouse for projects across a range of sectors including residential, infrastructure and energy

·Bat roost assessments, emergence surveys and licensing work

·Dormouse surveys, licencing and mitigation work

·Nutrient Neutrality assessments to assess impacts residential housing may have on European designated sites

·Habitat Regulations Assessments

We Lead with Science® and we encourage our team to share their findings with the industry (subject to sensitivities of timings and client permissions). We also encourage research-based elements to be brought into projects and many of the botanical projects we have worked on have resulted in publications and we encourage our team to continue to do this.

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.

Given the variety of projects we work on, we are looking for a Senior Ecologist who has strong field skills and ambitions to develop their technical skills in line with project requirements. With support from the regional and national ecology teams, and in line with our defined career framework, general development of expertise across many areas of ecology and particular technical specialisms will be encouraged. We have technical leads within the national team who can mentor and provide advice in key areas. We show our support for professional development through the provision of training, plus bonuses for achieving bat licences and charterships. 

Flexible Working:

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. We focus on talent and skills, not postcode. The role will require site work as well as working closely with ecologists, clients and colleagues from other teams so may require some time at an office or alternative working space to suit those involved. 

We are very happy to discuss flexible working for this role, including the possibility of reduced or compressed hours and flexible start or finish times. We can offer a range of solutions to help you get the most out of your work / life balance. We are supportive of flexible working but will require you to attend offices, events or sites as necessary to deliver the role.
