Job description

Powering the digital economy requires engineering that refuses to compromise on reliability. At Sustainable Infrastructure, we are engineering robust, forward-looking electrical networks for mission-critical facilities and advanced technological environments across the United Kingdom. If you thrive on solving complex electrical challenges and want to spearhead technical strategy from initial concept through to final delivery, step into a role where your technical vision shapes the backbone of critical infrastructure.

As a Power Systems Engineer based in the United Kingdom, you will take ownership of sophisticated electrical network design and analysis. Working alongside multidisciplinary engineering teams, you will champion technical excellence across high-profile data centre and mission-critical schemes, guiding clients and stakeholders through every stage of development.

Key Responsibilities

• Lead the design, modelling, and delivery of resilient electrical distribution systems for hyperscale data centres and critical infrastructure projects.
• Conduct comprehensive power system studies, including load flow, short circuit, protection coordination, transient stability, and arc flash assessments.
• Drive project decisions from conceptual master planning through to detailed design and commissioning.
• Direct multidisciplinary engineering teams, fostering technical collaboration and ensuring adherence to exacting engineering standards.
• Manage client relationships and technical interfaces, translating complex operational requirements into robust engineering solutions.

Required Skills & Experience

• A degree in Electrical Engineering or an equivalent discipline (BEng, MEng, or recognised equivalent).
• Chartered Engineer (CEng) status or actively working towards professional registration with an accredited institution.
• Proven track record in power systems analysis, design, and project delivery within data centres, critical infrastructure, utilities, or renewable energy environments.
• Deep technical expertise in executing system studies such as short circuit, protection coordination, and load flow analysis.
• Demonstrated hands‑on proficiency with industry‑standard power systems software, including ETAP, SKM, or DIgSILENT PowerFactory.
• Strong leadership capability with experience steering multidisciplinary design teams and managing key client relationships.

Nice-to-have

• Exposure to high-voltage grid connections and utility interface requirements.
• Familiarity with international electrical standards, regulatory compliance, and resilience benchmarking for mission‑critical environments.
• Practical knowledge of integrating renewable power generation or energy storage systems into critical electrical networks.

Why Join Sustainable Infrastructure

Stepping into this role means taking a central seat on projects that underpin modern society's digital and operational demands. At Sustainable Infrastructure, you will directly influence the technical architecture of complex, high‑stakes infrastructure, collaborating with high-calibre engineers on complex challenges and shaping power strategy for the industry's most demanding facilities.
