We are looking for an experienced and motivated marine scientist to join Defra's Marine Biodiversity & Environment Science and Monitoring Team. This is an exciting opportunity to work at the heart of government, providing scientific expertise on Marine Protected Areas (MPAs), Highly Protected Marine Areas (HPMAs), marine nature recovery and the UK Marine Strategy.

You will lead and manage high-profile monitoring and research projects, commission and oversee evidence activities, and translate complex scientific findings into clear, practical advice that supports policy and decision-making. deliver robust evidence that supports marine environmental outcomes. You will work closely with an experienced network of scientists, policymakers and evidence partners across Defra, its Arm's Length Bodies and the wider marine science community to deliver robust evidence that supports marine environmental outcomes.

We're looking for someone with strong scientific expertise, excellent communication and influencing skills, and a collaborative approach to working across organisational boundaries. You will be naturally curious, proactive and solutions-focused, able to identify emerging evidence needs, develop new research opportunities and build effective partnerships to tackle complex environmental challenges.

You will also provide line management to one direct report and technical support within the marine habitats and marine nature recovery area, helping to develop colleagues and ensure the delivery of high-quality scientific evidence.

This role offers an excellent opportunity to contribute to nationally important marine biodiversity monitoring programmes, develop innovative evidence approaches, and help inform the sustainable management and recovery of the marine environment.

This high‑profile role provides scientific expertise and evidence to support Defra policy teams and Government in conserving the marine environment, with a particular focus on marine habitats and marine nature recovery. The post holder will lead delivery of Defra's marine habitat evidence and monitoring programme across Marine Protected Areas (MPAs) and Highly Protected Marine Areas (HPMAs), and relevant UK marine strategy descriptors alongside associated research and development (R&D) that delivers insights into the condition, recovery/restoration, conservation and sustainable use of the marine environment.

The role is responsible for translating evidence into clear, actionable advice for policy colleagues, supporting delivery of Government ambitions under the Environmental Improvement Plan (EIP) and informing continuous improvement in marine monitoring. Strong collaboration with Defra Arms Length Bodies (ALBs), Statutory Nature Conservation Bodies (SNCBs), and the wider scientific community is essential to drive strategic alignment and deliver shared marine environmental goals.

The post holder will also provide leadership and line management for staff working on marine habitats and marine nature recovery within the Marine Biodiversity & Environment Science & Monitoring Team.
