Electrical Engineer – Battery Energy Storage Systems (BESS) | Edinburgh | £45,000 – £60,000 Design the power systems accelerating the clean energy transition.

At StorTera, we design and deliver advanced commercial-scale battery energy storage and ultra-rapid EV charging solutions that help stabilise the grid, unlock renewable generation, and decarbonise energy-intensive operations.

As we scale our project portfolio, we’re looking for an Electrical Engineer to play a key role in taking our BESS projects from concept to commissioning — shaping real infrastructure that will power the future.

If you thrive on complex electrical systems, grid-connected assets, and seeing your designs come to life in the field, this is your opportunity to make a tangible impact.

The Role:

You’ll be a core technical contributor across the full project lifecycle, leading the electrical design and delivery of commercial and utility-scale battery energy storage and EV charging projects.

Working closely with software, mechanical, civil, and project teams, you’ll ensure StorTera’s systems are safe, compliant, efficient, and grid-ready — from initial design through to commissioning and operational support.

This is a hands-on role with real ownership, visibility, and technical depth.

Key Responsibilities of the Electrical Engineer:

Design electrical systems for commercial BESS and ultra-rapid EV charging projects, including single-line diagrams, panel layouts, wiring diagrams, and equipment specifications (inverters, transformers, switchgear, protection relays, batteries)
Perform power system studies, including short-circuit, load flow, and protection coordination analysis
Ensure compliance with relevant national and international electrical codes and standards (IEEE, IEC, UL, etc.)
Collaborate cross-functionally with project managers, mechanical and civil engineers, software developers, and commercial teams
Develop technical specifications and bid packages for electrical equipment and services
Support procurement, construction, commissioning, and operations, providing expert guidance and troubleshooting
Conduct site assessments and resolve project-specific electrical challenges
Engage with clients, presenting technical solutions and responding to complex requirements
Continuously improve engineering processes, tools, and best practices
Mentor junior engineers and contribute to a strong engineering culture
What We’re Looking For:

Degree in Electrical Engineering or similar accredited discipline
Experience delivering commercial or utility-scale energy storage, solar PV, EV charging, or power generation projects
Strong knowledge of power electronics, battery technologies (Li-ion preferred), and grid interconnection requirements
Proficiency with electrical design and analysis tools such as AutoCAD Electrical, ETAP, SKM PowerTools, PSS/E, or PSCAD
Hands-on experience with key standards including IEEE 1547 and UL 9540
Excellent problem-solving skills, attention to detail, and a commitment to engineering quality
Confident communicator who works well with both technical and non-technical stakeholders
A values-driven engineer with a clear commitment to safety, sustainability, and societal impact
Developing engineers encouraged: We’re happy to consider candidates with less than 5 years’ experience. If you have strong fundamentals and ambition, we’ll provide structured training and mentoring, with a remuneration package aligned to your development pathway.

Why StorTera?

Work on cutting-edge energy storage and EV infrastructure shaping the future of clean power
Take ownership of real, grid-connected projects from design to delivery
Join a collaborative, innovative team that values expertise, learning, and initiative
