Job summary

RED ENGINEERING DESIGN LIMITED in London, Newcastle or Bicester seeks an Associate Electrical Engineer to lead DC power systems for AI-ready data centres. The role develops in-house DC design capabilities and reference designs, collaborating with R&D and acting as the central expert for DC power system design, modelling and assurance.

You will work across regions to define architectures, interfaces with UPS, energy storage, and AC/DC interfaces, while advancing standards and practical design

Qualifications

• Deep technical understanding of DC power distribution principles and topology.
• Knowledge of power electronics, switching, protection, and fault mitigation.
• Experience with data centre or AI infrastructure DC architecture concepts.
• Strong power modelling capability using recognised tools and advanced spreadsheets.
• Ability to compare AC/DC options for high-density AI data centre applications.
• Ability to develop earthing, bonding, and fault management for DC systems.
• Familiarity with UK, European, and international standards.
• Ability to produce clear design narratives and technical reports.
• Excellent communication and stakeholder management skills.
• Ability to work across multiple teams and regions in a central advisory role.

Responsibilities

• Establish RED’s in-house DC design and power modelling capability for high-density AI data centre infrastructure.
• Develop RED reference designs for DC AI factory infrastructure solutions, initially through close collaboration with the R&D team.
• Act as RED’s central subject matter expert for DC power system design, modelling, integration and technical assurance.
• Create practical design guidance, calculation methods and training pathways to upskill existing AC electrical designers into combined AC and DC designers.
• Lead the technical development of DC power distribution concepts for AI-ready, high-density data centre environments.
• Develop DC power system studies covering load flow, voltage drop, converter behaviour, prospective fault conditions, protection selection, fault interruption, discrimination, resilience and maintainability.
• Define DC reference architectures for RED’s AI factory infrastructure solutions, including interfaces with AC utility supplies, transformers, rectification or conversion stages, UPS or energy storage systems, busbar or cable distribution and rack-level power delivery.
• Assess equipment availability, certification, product maturity, standards compliance, maintainability and local approval requirements.
• Support R&D in testing design options, comparing AC and DC distribution approaches, and establishing design rules for reference solutions expected to become relevant in Europe over the next 6 to 12 months.
• Develop technical standards, design notes, quality checklists and calculation templates for DC power systems within RED’s project delivery and technical review process.
• Advise project teams on DC system topology, safety, earthing and bonding, isolation, protection, maintainability, commissioning and integration with wider data centre power infrastructure.
• Represent RED in technical discussions with clients, technology partners, suppliers and contractors where DC power infrastructure is being considered.
• Support bids, early-stage advisory work and client-facing technical strategy for AI, high-density compute and future data centre power architectures.
• Train, mentor and upskill electrical engineers across RED to develop practical DC design competence alongside existing AC electrical design capability.
• Maintain awareness of developing standards, product ecosystems, European market direction and technology roadmaps associated with DC power systems for data centres.
