Senior Ecologist

Shape Environmental Outcomes Across the UK and Ireland

Tetra Tech is seeking to appoint a Senior Ecologist to join our Planning & Environmental team. Based in our Belfast office, this role offers the opportunity to contribute to a wide range of ecological, environmental and planning projects across the UK and Ireland.

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 multi disciplinary environment provides exposure to a wide range of significant projects, including marine, coastal, regeneration and renewable related developments.

As a Senior Ecologist, you will be responsible for delivering high‑quality ecological input across a wide portfolio of projects. You will take a lead role in designing and undertaking ecological surveys, interpreting data, assessing habitats and species, and producing clear, robust and well‑structured reports to support planning applications, marine licensing processes and related environmental approvals. You will liaise with clients, regulators, colleagues and wider project teams to ensure that ecological considerations are integrated into planning, design and construction from the outset.

You will support the coordination of multidisciplinary project teams, contribute to feasibility assessments, undertake research and analysis, and represent Tetra Tech in community or stakeholder consultations where required. Your work will combine office‑based report writing with site‑based survey activity throughout the UK and Ireland, offering a varied and engaging workload across different landscapes and development types.

You will play an important role in shaping sustainable design approaches, identifying mitigation measures and supporting the delivery of nature‑positive solutions that contribute to environmental resilience.

As you progress in the role, you will further develop your sector expertise, contribute to technical leadership within the ecology team and support the continual improvement of our methodologies, reporting standards and client service. Your contribution will be reflected in the clarity of your advice, the confidence you inspire in clients and the added value you bring to complex environmental and planning projects.
