Electrical Engineer - Battery Energy Storage Systems in Edinburgh

You’ll be joining a globally respected energy solutions provider at the forefront of utility-scale battery energy storage. With a strong track record in grid-connected projects and an international footprint, the business delivers full turnkey BESS solutions for some of the most complex and demanding sites across Europe. They combine deep engineering expertise, in-house R&D, and proven project delivery capability to help developers, IPPs and utilities bring technically robust, bankable projects to life. With growing demand in the UK and Ireland, the team is expanding and now looking for an Electrical Engineer who wants to sit close to the commercial action while still working hands-on with system design.

As Electrical Engineer, you’ll sit within the commercial team and act as the technical backbone for bids, tenders and customer proposals. From the first enquiry, you’ll interpret client specifications, develop electrical concepts and single line diagrams, size key components, and support the configuration of battery, inverter and balance-of-plant equipment. You’ll work closely with Senior Tendering Engineers and the sales team to translate customer requirements into compliant, optimised technical solutions - including layouts, loss calculations, cable schedules and protection philosophies – while feeding into costings and pricing models. You’ll liaise with product and R&D teams to validate configurations, support grid connection studies with an understanding of DNO/TSO requirements, and prepare the technical sections of proposals, presentations and clarifications. Over time, you’ll become a go-to person for practical design input on live opportunities, helping shape projects that can be delivered safely, efficiently and profitably.

You’ll be a degree-qualified Electrical or Power Engineer and have some experience working on either BESS or solar projects. You understand how electrical systems are put together in the real world, from concept design and equipment selection through to installation and commissioning, and you are comfortable reading and producing single-line diagrams, cable sizing, and protection/coordination concepts. Exposure to grid-connected projects, DNO/TSO interfaces, and standards such as G99 or equivalent is highly valued. You enjoy working at the intersection of technical detail and commercial decision-making, are confident speaking with both engineers and non-technical stakeholders, and can balance compliance, performance and cost when proposing solutions. Prior experience supporting tenders, proposals or design-and-build EPC projects in BESS or renewables would be a strong advantage.

You’ll join a growing, international business where engineering is genuinely central to commercial success. This role gives you direct visibility of major deals, close collaboration with senior sales and technical leaders, and a clear path to progress into senior tendering, applications or project engineering positions. You’ll work on high-impact BESS schemes that are shaping how storage is deployed across the UK and Europe, with access to strong technical resources, supportive leadership, and cross-border project exposure. Alongside a competitive salary and performance-related bonus, you can expect flexible working, ongoing professional development, and the chance to build a career at the cutting edge of grid-scale energy storage.
