About the Role

Chelgrave Contracting is seeking experienced people for our client in the power electronics and industrial power systems industry, based in a workshop in South West Sydney. Our client designs, repairs, and services power conversion equipment including UPS systems, rectifiers, industrial chargers, and battery storage solutions.

We're looking for a hands-on Power Electronics Technician who can diagnose and repair complex electronic and power systems to a high standard, working both independently and as part of a close-knit team.

Key Responsibilities

• Systematic fault-finding using multimeters, oscilloscopes, meggers, and power analysers
• Component-level repair — soldering, wiring, PCB diagnostics, and module replacement
• Working confidently across AC/DC principles, three-phase systems, and power conversion (AC-DC, DC-DC, DC-AC)
• Reading and interpreting electrical schematics
• Servicing lead-acid and lithium-ion battery systems
• Reverse-engineering and diagnosing from first principles when documentation is missing or incomplete

Essential Requirements

• Australian Citizen or Permanent Resident (some future work is defence-related)
• Current NSW driver's licence
• 3+ years' practical experience in power electronics, industrial electrical, or complex electronic repair
• Demonstrated safe work practices, including the ability to work safely and unsupervised on live/DC systems

Highly Regarded

• Living in South West Sydney or within a reliable daily commute
• Trade Certificate, Diploma, or military technical trade qualification
• IPC-7711/7721, J-STD-001, or IPC-A-610 certification (or similar)
• Electrical licence (held or working towards — support provided to attain)
• Prior experience with UPS, rectifiers, industrial chargers, or battery storage
• ADF background (RAAF/RAN/Army electrical, avionics, electronics, or comms-electronics trades) — veterans strongly encouraged to apply
• Eligibility for an Australian security clearance

About You

• A self-starter who works autonomously without needing step-by-step instructions
• A natural troubleshooter who's comfortable with ambiguity and unfamiliar systems
• Resourceful and curious — you like pulling things apart to understand them, and finding alternatives when parts are obsolete
• Quality-focused — you take pride in repairs that last
• Reliable and flexible, with strong ownership through to completion
