Energy Consultant
A leading engineering and sustainability consultancy is looking to appoint an Energy Consultant to join its growing Sustainability & Building Performance team.
With a strong reputation for delivering innovative, low-carbon solutions across the built environment, the business works on a diverse range of projects spanning commercial, residential, healthcare, education, science and technology sectors. Sustainability and building performance sit at the heart of its approach, with continued investment in developing industry-leading expertise across energy modelling, Net Zero Carbon and building optimisation.
This is an excellent opportunity for someone with 1–2 years' experience to develop their technical skills, work on a variety of interesting projects and build their career within a highly respected sustainability consultancy.
The Opportunity
As an Energy Consultant, you'll support the delivery of building performance analysis and energy modelling across a range of development projects. Working alongside experienced sustainability consultants, engineers and design teams, you'll gain exposure to projects from the early design stages through to completion.
The role is particularly suited to someone with hands-on experience using IES VE who is looking to further develop their expertise across energy modelling, building performance and sustainable design.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
