Senior Design Engineer – V

We are looking for an experienced Senior Design Engineer with a strong background in HV electrical networks up to 33kV to join our growing team.

This is a senior technical role where you will take ownership of 11kV/33kV electrical designs, supporting renewable energy projects and associated network connections from initial feasibility and tender stage through to detailed design and construction.

You will lead the development of technically robust and practical design solutions, working closely with clients, DNOs/IDNOs and internal project teams to ensure designs meet technical, regulatory, safety and delivery requirements.

If you have strong experience in HV infrastructure, substations and cable design and are looking for a role where you can take greater technical ownership of projects, we would love to hear from you.

This is a hybrid role with flexibility depending on location. Our preferred office base for this position is our Scotland HQ. We are looking for someone who can work from one of our offices at least 3 days per week, or attend for one full week at a time if primarily remote-based.
