Ecologist
Shape Environmental Outcomes Across the UK and Ireland
Tetra Tech is seeking to recruit Ecologists to join our Planning & Environmental team. Based in our Belfast office, this role offers an exciting opportunity to contribute to ecological, environmental and planning projects across the UK and Ireland while developing your technical skills within a supportive, multidisciplinary environment.
The position is based in a large, permanently desked office located on the edge of the city with on‑site parking, strong public transport connections and easy access to major road networks. The role supports hybrid working, with an expectation of two to three days per week in the office to facilitate mentoring, collaboration and team coordination. Flexible working arrangements can be accommodated where project responsibilities allow. The multidisciplinary environment provides exposure to a wide range of significant projects, including marine, coastal, regeneration and renewable‑related developments.
Purpose & Scope of the Role
As an Ecologist, you will support the delivery of ecological assessments, field surveys and environmental reporting across a broad portfolio of projects. You will assist in the planning and completion of ecological surveys, help collect and analyse data, and contribute to the preparation of clear, structured ecological reports for planning and environmental submissions. Working alongside more senior colleagues, you will help ensure that ecological considerations are integrated into project design and development from the outset.
Your role will include supporting desk studies, feasibility assessments, stakeholder engagement activities and the coordination of multidisciplinary project teams. You will balance office‑based reporting with site visits across the UK and Ireland, gaining experience across a range of habitats and species. You will also work closely with senior members of the team, contributing to client relationships and helping to strengthen the ecological service offering as your experience grows.
Your Impact in this Position
Your contribution will play an important role in gathering accurate ecological data, supporting the preparation of environmental assessments and helping identify opportunities to protect and enhance biodiversity. You will help clients understand ecological constraints and contribute to the development of proportionate, nature‑positive solutions. Your work will support sustainable design, informed decision‑making and the delivery of environmental outcomes that contribute to resilient and responsible development.
As you grow within the role, you will expand your fieldwork experience, develop your technical knowledge and build confidence in delivering ecological inputs independently. You will contribute to the team’s continued commitment to high-quality science, clear communication and consistent service delivery. Your progression will be reflected in your developing technical capability, the reliability of your reporting and the trust you build with colleagues and clients.

You will have an interest in bat, mammal and wider ecological survey methods, together with a developing understanding of habitat classification, species identification and ecological appraisal. You will be keen to build your technical capability, apply scientific principles accurately and develop the practical skills needed to deliver high‑quality ecological assessments.
Stakeholder & Client Engagement

You will begin applying this knowledge to support ecological mitigation, enhancement and compliance measures. As your experience grows, you will develop increased confidence in navigating regulatory processes, interpreting legislation and contributing to proportionate, evidence‑based ecological recommendations.
