Key Responsibilities
Systematic fault-finding using multimeters, oscilloscopes, meggers, and power analysers

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 protected 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 adaptable, with robust ownership through to completion
