Senior Ecologist
Tetra Tech is looking for a Senior Ecologist to join our high-performing ecology team in delivering technically robust, commercially aware solutions across renewable energy, residential, commercial, and infrastructure projects throughout the UK.
Join Us in Shaping the Future of Sustainable Ecology
This is an opportunity to contribute to complex, high-profile work that supports the transition to clean energy and sustainable development, while developing your expertise across a varied and meaningful project portfolio.
Purpose & Scope of the Role
As Senior Ecologist, you will manage a varied portfolio of ecological projects, typically 4–6 at any one time, delivering work in line with UK legislation, planning policy, and ecological best practice. You will contribute to an exciting range of projects across renewable energy, residential, commercial, and infrastructure sectors, including Town and Country Planning Act developments and Nationally Significant Infrastructure Projects.
You will play a key role in producing high-quality ecological outputs, supporting project delivery from survey and assessment through to mitigation and stakeholder engagement. Depending on experience, the role may also include line management responsibilities and support the development of junior ecologists.
This is a role for an ecologist who combines strong technical capability with commercial awareness, confidence in client-facing environments, and a collaborative approach to delivery.
Your Impact in This Position
You will help shape the success of both regional and national ecology work by contributing technical excellence, sound judgement, and practical solutions to complex projects. Your work will directly support the delivery of major schemes and help maintain a strong reputation for quality, innovation, and sustainable outcomes.
Through your input, the team will be better equipped to deliver timely, pragmatic ecological advice, secure successful project outcomes, and strengthen client relationships. You may also influence the development of future ecological talent through mentoring, support, and knowledge sharing.
