Overview

We have an exciting opportunity for a dynamic and motivated Assistant Sustainability Consultant. We are seeking candidates who are looking to work on some of the largest and most interesting sustainability and carbon projects in the UK and internationally. The position is permanent with the opportunity for hybrid home/office working.

We are seeking someone who prides themselves on delivering technically excellent work, with strong analytical and reporting standards, and who embraces innovative approaches to sustainability assessment. In this role, you will work on life cycle assessments (LCA), embodied carbon studies, and sustainability certification deliverables (LEED, BREEAM etc), supporting low-carbon strategies across infrastructure and built environment projects. You will contribute to data collection, modelling, and interpretation, and help embed whole-life carbon principles into design and procurement decisions.

You will collaborate with a wider team of professionals across disciplines to provide integrated sustainability solutions to our clients.

We look forward to hearing from aspiring consultants who are passionate about sustainability. While prior experience in LCA or certification is desirable, what matters most is your drive, enthusiasm, and willingness to learn and grow in this evolving field.
