Electrical Designer - 3D Modelling

Job Description: Senior Electrical Designer (3D Modelling)

Role Purpose

The Senior Electrical Designer (3D Modeller) plays a critical role in translating complex conceptual designs into high-quality, constructible 3D models and detailed engineering drawings. Working within a multidisciplinary team, you will design heavy industrial electrical infrastructure, power systems, and instrumentation layouts for large-scale global projects.

Key Responsibilities

• Develop accurate, interference-free 3D models of electrical and instrumentation systems, including cable trays, substations, switchrooms, lighting, and earthing networks.
• Generate detailed engineering deliverables such as general arrangements, layout drawings, cable routing diagrams, single-line diagrams (SLDs), termination schedules, and schematic diagrams.
• Collaborate closely with structural, mechanical, and piping designers to resolve 3D model clashes and ensure a seamless, integrated design.
• Ensure all designs comply with relevant engineering standards (e.g. Australian Standards), safety regulations, and project-specific client specifications.
• Participate in and lead model reviews with internal engineering teams and external project stakeholders.
• Provide guidance, technical support, and drafting checks for junior and intermediate designer team members.

Technical Skills & Qualifications

• Education: Advanced Diploma in Electrical Engineering, Associate Degree, or equivalent technical qualification/trade background.
• 3D Software Expertise: Advanced proficiency in MicroStation 3D or AutoCAD 3D is highly essential. Experience with OpenBuildings, ProStructures, or Smart 3D is a distinct advantage.
• Industry Experience: Minimum of 5–8+ years of design experience within the heavy industrial sector, specifically focusing on mining, mineral processing, or materials handling projects.
• Technical Knowledge: Deep understanding of industrial plant layouts, electrical equipment positioning, cable management design, and vendor data extraction.
• Standards Awareness: Working knowledge of regional electrical standards (such as AS/NZS 3000) and industrial safety standards.

Soft Skills & Attributes

• Strong spatial awareness and a sharp eye for design detail.
• Excellent verbal and written communication skills to articulate design concepts to non-technical stakeholders.
• A collaborative mindset with the ability to manage competing priorities under tight project deadlines.
