About the Role
Mace combines construction expertise with consultancy to unlock potential in every person or project and redefine the boundaries of ambition. As a purpose-led organisation, we place diversity and inclusion at the heart of everything we do. Our responsible business practice group, comprising 150+ people, is dedicated to creating a low carbon resilient world, shaping cities, building thriving communities, and helping clients realise their ambitions.

This exciting opportunity is for a qualified ecologist experienced in delivering biodiversity net gain (BNG) to join Mace’s responsible business team. You will be part of our growing nature-based solutions team, delivering BNG and sustainable development across key consultancy projects in various sectors. You will support innovative and technically challenging low carbon projects, working with sustainable and pioneering clients aiming to deliver at least +10% biodiversity net gain, technical ecology advice, nature-based solutions for climate change, and BREEAM outstanding standards.

This role is ideal for someone with a profound understanding of BNG delivery and management, alongside strong knowledge of sustainability aligned with current and future trends in the built environment. You will inspire, challenge, guide, and help deliver our sector-leading sustainability targets outlined in our 2026 business priority, Pursue a Sustainable World.

Key responsibilities include supporting project feasibility and early design layout with design teams applying mitigation hierarchy principles; managing delivery of Phase 1 and UKHab surveys, species surveys, river condition assessments, preliminary ecological appraisals (PEA), ecological impact assessments (EcIA), environmental statements, and habitat regulations assessments (HRA). You will support commissioning these surveys, prepare technical scopes for sub-consultants, and develop strong working relationships.

Additional duties include completing Defra’s biodiversity metric, supporting landscape architects with urban greening factor (UGF) targets, preparing biodiversity gain plans, leading stakeholder engagement for biodiversity offset opportunities, engaging with off-site biodiversity unit providers, advising on biodiversity statutory credits, and collaborating with local authorities on biodiversity management.

You will also support natural capital and ecosystem service assessments using the Environmental Benefits from Nature tool, contribute to Mace’s natural capital reporting service, assist with BREEAM assessment reporting, perform GIS mapping, and work with landscape architects to deliver green infrastructure plans, nature-based solutions, and biodiversity requirements.

Technical assurance of ecology and biodiversity assessments and reports, landscape and ecological management plans (LEMP), habitat management and monitoring plans (HMMP), and construction environmental management plans (CEMP) will be part of your remit. You will support environmental and social appraisals (ESA) as needed, work with construction project teams to deliver best practice ecology protection and enhancement, and manage biodiversity on construction sites as the ecological clerk of works (ECoW).

Additional responsibilities include supporting SITES assessment delivery on new construction projects, managing licence applications including mitigation and monitoring, advising clients on strategic ecology priorities and nature-based solutions, writing policies, developing portfolio/estate-wide strategies, delivering training, and mentoring junior team members.

Mace is committed to a safe, diverse, and inclusive working environment, championing wellbeing and continuous improvement. We welcome applications from a diverse range of candidates and offer flexible working options where suitable.
