Critical Power Architect (Solution Engineer)

Location: London, UK. You'll be part of a global team and work closely with colleagues based at our Data Centre Centre of Competence in The Hague, Netherlands.

Are you passionate about designing resilient, efficient and sustainable power infrastructure for data centres? We're looking for a Critical Power Solution Engineer to join Siemens' global Data Centre Centre of Competence, supporting the design and delivery of critical power solutions for hyperscale and colocation data centre projects.

In this customer-facing role, you'll work with data centre operators, consultants, engineering partners and contractors to develop integrated solutions across the critical power infrastructure, including medium- and low-voltage distribution, transformers, UPS systems, battery energy storage and automation technologies. You'll play a key role throughout the sales and project delivery lifecycle, translating customer requirements into technically robust and commercially effective solutions.

We recognise that candidates may bring different levels of experience across the critical power and data centre sectors. During the selection process, we'll assess your technical knowledge, solution development capabilities and stakeholder engagement experience to determine the most appropriate level and responsibilities within the team.

What You'll Do

• Lead the design and development of end-to-end critical power infrastructure solutions for hyperscale and colocation data centres, defining electrical architectures, topology, redundancy strategies and medium- and low-voltage distribution systems.
• Translate customer requirements, concept designs and technical specifications into engineered solutions, producing key deliverables including single-line diagrams, load schedules, technical narratives, interface definitions and solution descriptions.
• Act as the technical lead throughout the project lifecycle, making and defending design decisions while balancing reliability, risk, cost, programme, maintainability, scalability and energy efficiency requirements.
• Build trusted relationships with customers, consultants, contractors and internal stakeholders, providing technical leadership and ensuring solutions align with client objectives and operational needs.
• Collaborate with multidisciplinary teams to deliver integrated solutions incorporating switchgear, transformers, UPS systems, battery energy storage, automation, monitoring and supporting mechanical systems, including modular and factory-built solutions where appropriate.
• Support business development and sales activities through technical strategy, bid development, value engineering, customer presentations, technical clarifications and solution optimisation.
• Coordinate interfaces across electrical, mechanical, controls, civil and operational disciplines, managing technical risks, design reviews, change requests and project execution activities.
• Maintain a focus on the full asset lifecycle, considering commissioning, monitoring, maintainability, future expansion and continuous improvement to deliver resilient and sustainable critical power solutions.

About You

• Degree qualified in Electrical Engineering, Power Engineering or a related discipline, or equivalent industry experience.
• Experience designing power transmission and distribution systems across medium- and low-voltage applications.
• Broad understanding of critical power infrastructure and how systems such as switchgear, transformers, protection systems, UPS and battery systems integrate.
• Experience managing multiple projects and competing priorities, while considering technical, commercial and compliance requirements.
• Strong communication and stakeholder management skills, with the ability to explain technical concepts and design decisions to a range of audiences.
• Understanding of multidisciplinary engineering and interface management across electrical, mechanical, controls and civil disciplines.

Advantageous:

• Experience within critical environments, such as data centres.
• Familiarity with data centre design principles.
• Knowledge of relevant industry standards, such as IEC standards.
• Experience working with customers, consultants and contractors in the development and delivery of technical solutions.
