Job description

Principal Electrical Engineer, Power Systems

Employment Type: Full-time / Permanent

Company Overview

A leading end-to-end power solutions and services provider specialising in critical power infrastructure across a range of high-demand sectors including data centres, power generation, healthcare, oil & gas, pharmaceuticals, semiconductors, and industrial facilities.

With over 1.5 million square feet of US manufacturing capacity, the company integrates engineering, manufacturing, modular deployment, and lifecycle services under one platform, delivering scalable and resilient infrastructure where uptime is non-negotiable. The company supports clients across the full project lifecycle, from design through to commissioning and ongoing maintenance.

Role Overview

The Principal Electrical Engineer will serve as a subject matter expert and technical authority on large-scale power infrastructure projects. This is a hands‑on technical leadership role — not a people management position — working directly with customers and project teams to design and deliver complex, mission‑critical electrical systems.

Key Responsibilities

• Lead end-to-end electrical system design for industrial and mission-critical projects.
• Own system architecture across MV/LV distribution, substations, and backup power systems.
• Act as technical authority on complex, high-value projects.
• Develop and review single line diagrams, protection and coordination studies, schematics, and equipment layouts.
• Partner directly with customers to define robust and scalable power solutions.
• Provide technical leadership across multiple concurrent projects.
• Mentor engineers and elevate technical capability across the team.
• Shape engineering standards and system design approaches.

Skills & Qualifications

• 15–20+ years of experience in electrical engineering.
• Deep expertise in industrial power systems including MV/LV distribution, substations, switchgear, transformers, generators, and UPS systems.
• Strong experience in protection and coordination, with SEL relays preferred.
• Background in industrial, utility, data centre, or large infrastructure projects.
• Experience working within industrial engineering firms or EPC environments.
• PE license highly preferred.
• Master’s in physics, Mathematics, or a related field highly desirable.
