Job Purpose

Principal Electrical Designer provides senior-level design leadership and technical expertise for electrical design deliverables across major projects. This role is accountable for the quality, consistency, and timely delivery of complex electrical design packages in support of Worley and its customers, while providing technical mentorship to electrical design teams.

• Lead and deliver high-quality electrical design services that meet Worley, client, and applicable statutory and regulatory requirements, on time and within budget.
• You will be accountable for:
• Leading the development, coordination, and quality assurance of electrical design deliverables across the full project lifecycle (concept, FEED, detailed design, and construction support).
• Providing technical direction and oversight to electrical designers and drafting teams, including task assignment, workload planning, and design reviews.
• Participating in project planning, progress reporting, and compliance with required checking and quality assurance procedures.
• Ensuring project scope is clearly defined and that changes are managed in accordance with project change management processes.
• Supporting procurement, construction, and commissioning activities, including:
• Review of electrical equipment requisitions and technical bid evaluations
• Input to purchase orders and vendor documentation
• Resolution of site and vendor queries
• Coordinating closely with multidisciplinary engineering disciplines (instrumentation, process, mechanical, piping, and automation) to ensure fully integrated electrical designs.
• Proactively identifying and resolving discrepancies between Worley and client design standards and requirements.
• Providing technical input into constructability, maintainability, and operability reviews.
• Supporting and mentoring junior designers and engineers, fostering technical excellence and knowledge sharing within the electrical design team.
• Communicating effectively with project stakeholders, including clients, vendors, and construction partners.
• Identifying technical risks and issues, developing practical solutions, and escalating when appropriate.

• Extensive experience delivering complex electrical design on industrial projects (e.g., energy, mining, chemicals, power, or infrastructure).
• Strong working knowledge of electrical design systems, workflows, and document management tools (e.g., SAP, KMS, or similar project systems).
• Solid understanding of project scope development, workshare execution, and delegation of design activities across internal and external teams.
• Familiarity with process safety and operability considerations (e.g., participation in HAZOP/LOPA reviews where electrical systems interface with process safety functions).

• Electrical single-line diagrams and schematics
• Equipment layouts and electrical room layouts
• Cable schedules, cable routing, tray and conduit layouts
• Power distribution and load lists
• Motor control center (MCC) layouts and schematics
• Grounding and bonding drawings
• Lighting and small power layouts
• Area classification and hazardous area electrical layouts
• Bills of material
• Material requisitions
• Construction and engineering work packages

• Low and medium voltage power distribution systems
• Motor control and variable frequency drives (VFDs)
• Lighting systems (industrial and outdoor)
• Grounding, bonding, and lightning protection
• Hazardous area electrical design and applicable codes/standards

• Accredited Engineering Technology, Design, or related technical qualification (Engineering degree or diploma preferred).
• Extensive experience in senior-level Electrical design roles on large, multidisciplinary projects.
• Demonstrated ability to interpret, develop, and review complex electrical drawings, schematics, and technical documentation.
• Strong communication, coordination, and problem-solving skills.

• Professional designation or eligibility for professional certification relevant to design or engineering disciplines (e.g., APEGA, ASET, or equivalent).
