Job description

In this role as Senior Auxiliary Systems Engineer within the HVDC Engineering Plant Electrical Design (TPE) team, you'll take responsibility for auxiliary power systems essential to safe, reliable converter station operation. Working with customers, suppliers and multidisciplinary engineering teams, you'll turn complex requirements into coordinated designs, manage interfaces and scope changes, and drive delivery against programme, cost and quality commitments. Your technical scope will span system design, selectivity studies, equipment specifications, cables and cable transit systems, covering auxiliary transformers, medium- and low-voltage switchgear, diesel generator systems, batteries and uninterruptible power supplies (UPS). If your background is in transmission, oil and gas or offshore engineering, this is an opportunity to apply your experience where technical depth and project delivery come together.

Location: Glasgow Office

Working Pattern: Hybrid, 3 days office / 2 days home

(Please note we are unable to provide visa sponsorship for this position and right to work in UK is required)

How you'll make an impact

• Develop cableway designs for the main plant across the HVDC converter station.
• Prepare technical specifications for auxiliary power systems, including medium- and low-voltage switchgear, auxiliary transformers, diesel generator systems, batteries, uninterruptible power supplies (UPS) and cables
• Coordinate design interfaces with protection and control, automation and main plant engineering teams.
• Bring engineering disciplines together, working with civil engineering and BIM teams to identify and resolve clashes and turn individual designs into coordinated solutions.
• Manage supplier and vendor interfaces to keep technical deliverables aligned with project requirements.
• Lead design reviews with customers and equipment suppliers, using your technical judgement to resolve issues, confirm compliance with the agreed scope and manage scope changes.
• Drive scope and programme management for your deliverables: coordinate dependencies, monitor progress and address emerging issues before they compromise delivery commitments.
• Take ownership of your contribution to the department's auxiliary power equipment scope, working with the design team to maintain clear responsibilities and coordinated delivery for HVDC stations
• Champion safe, reliable engineering while delivering to the agreed programme, cost and quality requirements.
• Put your knowledge ofstandards and requirements into practice, sharing your expertise to help the wider team apply them effectively.
• Apply your technical judgement to assess proposed solutions, constructively challenge assumptions and help shape robust engineering decisions grounded in a thorough understanding of the design.
• Build effective working relationships with external suppliers, contractors and customers to support coordinated project delivery.

Your Background

• You bring a demonstrated track record of taking technical ownership of complex auxiliary power systems or comparable electrical engineering packages, from defining requirements through to coordinated design and delivery.

• You exercise sound engineering judgement, lead technical reviews, guide other engineers and manage multidisciplinary and supplier interfaces. You can demonstrate effective scope and programme management, including managing change and resolving technical risks, with accountability for safety, quality, cost and delivery commitments.

• You bring relevant experience from transmission, oil and gas or offshore engineering, with a transmission project background considered advantageous.

• Your expertise may include auxiliary power systems, selectivity studies, or the installation and commissioning of low-voltage equipment. We welcome experienced engineers who can bring practical delivery insight to engineering design, as well as those with an established design background.

• Knowledge of CAD tools for electrical circuit diagrams and layouts would be an advantage.

• You understand local standards and requirements, including those of UK customers such as SSE and National Grid.

• You communicate confidently, building effective working relationships with international teams and UK customers.

• You combine a collaborative approach and energy with sound engineering judgement, the confidence to make decisions and a clear focus on delivery.

• The role may involve travel for customer and supplier meetings, as well as site supervision.
