Are you passionate about renewable energy and looking to play a key role in delivering high-quality commercial and industrial rooftop solar projects?

Cobalt is partnering with a rapidly growing renewable energy business that specialises in designing and delivering innovative rooftop solar PV solutions across the commercial, industrial and real estate sectors throughout the UK. Backed by strong investment and an impressive project pipeline, they are now looking to appoint a Junior Solar PV Designer to join their expanding team.

This is an exciting opportunity to join a business at the forefront of the UK's energy transition, where you'll have genuine responsibility, work on high-profile projects and contribute to the continued growth of the company.

The Role

As a Junior Solar PV Designer, you will take ownership of the design and technical delivery of commercial and industrial rooftop solar PV projects from initial feasibility through to installation. Working closely with project managers, engineers and external partners, you'll ensure solutions are technically robust, commercially viable and delivered to the highest standards.

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.
