Job description

Associate Director - Sustainability

A leading engineering and sustainability consultancy is looking to appoint an Associate or Associate Director to join its growing Sustainability team.

With a strong reputation for delivering innovative, low-carbon solutions across the built environment, this business works on a diverse range of high-profile projects spanning commercial, residential, healthcare, education, science and technology sectors. Sustainability sits at the heart of their approach, and they continue to invest heavily in expanding their expertise in Net Zero Carbon, building performance and environmental design.

This is an excellent opportunity for an experienced sustainability professional to take on a strategic leadership role within a highly respected consultancy, helping shape both project outcomes and the future growth of the team.

The Opportunity

You’ll play a key role in leading sustainability and building performance projects, developing client relationships, mentoring consultants and driving technical excellence across the business.

The role offers a balance of project delivery, leadership and business development, making it ideal for someone looking to broaden their impact while remaining involved in technically challenging and meaningful work.

Key Responsibilities

• Lead sustainability and building performance projects across a variety of sectors.
• Develop energy, carbon and sustainability strategies for new and existing developments.
• Work closely with clients, architects, developers and multidisciplinary design teams.
• Support the delivery of Net Zero Carbon and wider sustainability objectives.
• Mentor and develop members of the sustainability team.
• Contribute to business growth through client engagement, networking and proposal support.
• Help drive innovation and best practice across sustainability services.
• Support resource planning and successful project delivery across multiple commissions.

About You

We’re keen to speak with candidates who have experience within sustainability consultancy, building services engineering, environmental design or a related discipline.

You may already be operating at Associate level, or be a Senior/Principal Consultant looking for the next step in your career.

The ideal candidate will bring:

• Strong knowledge of sustainability and building performance within the built environment.
• Experience managing projects and engaging directly with clients.
• An interest in Net Zero Carbon, low-carbon design and environmental performance.
• Leadership capability and a collaborative approach to team development.
• Excellent communication and stakeholder management skills.
• Commercial awareness and a desire to contribute to business growth.

Experience with energy modelling, carbon assessments, building performance analysis, BREEAM, WELL or similar sustainability frameworks would be beneficial but is by no means essential.

Why Join?

• Join a highly respected consultancy with an excellent industry reputation.
• Work on complex and impactful projects across the UK.
• Play a key role in shaping the growth of an expanding sustainability team.
• Clear opportunities for career progression and professional development.
• Flexible working arrangements and a collaborative culture.
• Opportunity to make a tangible contribution to the UK's Net Zero ambitions.
