About SLR Consulting
SLR’s purpose is Making Sustainability Happen. We achieve this by having a team of expert advisors and technicians, who partner with our clients to tackle some of the world's most complex sustainability challenges, by utilising our collaborative and entrepreneurial One Team culture. SLR has been advising clients for over 25 years at every point of their project life-cycle. Starting as a UK business, we now operate as a global company with more than 3,000 people delivering client solutions across six regions. We have grown both organically and through welcoming other like-minded businesses with a similar One Team culture into the SLR group. We are ably supported by our principal investor, Ares Management, and will continue to build a balanced, successful and growing business. We’ve designed working life at SLR to look a little different. Because we know talented people often feel restricted by the rigid systems, lack of cross-functional collaboration and limited options for growth on offer elsewhere. Our One Team culture promotes meaningful professional and personal growth, our flat management structure provides many opportunities to progress, and our collaborative approach means you’ll get the chance to work on projects you care about and make a real difference. If you’re purpose-driven, self-motivated and keen to make an impact on a global scale, we want to hear from you.
