We’re looking for a Junior Electronics Engineer to join our R&D; team in Sydney. Working under the direct supervision of the R&D; Manager, you’ll support the research, design, development, testing, and validation of electronic systems and components for our medical and diagnostic device range.

We welcome recent graduates and candidates with little to no skilled experience (some academic/industry experience is a bonus). You’ll receive structured mentorship and managerial oversight throughout, you won’t be expected to make independent regulated design decisions.

Key Responsibilities

- Assist the R&D; Manager with research and development activities, including product prototyping and design optimisation for medical and diagnostic applications
- Support the translation of product requirements into practical electronic design solutions under managerial guidance
- Design, develop, debug, test and validate, as directed by the R&D; Manager on a project-to-project basis:
- Electronic circuits, schematic diagrams, and printed circuit boards (PCBs) using Altium Designer, EasyEDA, and other EDA tools
- USB communication systems, embedded electronic hardware, and high-speed data interfaces
- Power management and battery-powered electronic systems, including Battery Management Systems (BMS) and charging circuits





- Execute electrical/electronic test procedures to verify system functionality and performance against engineering requirements
- Support EMC pre-compliance activities, including PCB design modifications and technical documentation, under R&D; oversight
- Assist in prototype assembly, system integration, and testing of medical devices and associated electronic subsystems
- Investigate hardware and firmware failures and implement corrective actions to improve product reliability
- Prepare and maintain engineering documentation, including design specifications, test reports, validation records, Bills of Materials (BOMs), and engineering change documentation

Skill & Experience

Software / Design Tools

- Exposure to Altium Designer, EasyEDA, or similar EDA/PCB design software
- Familiarity with C/C++ for embedded/microcontroller firmware development
- Comfortable with engineering documentation (BOM management, revision control, test report writing)

Hardware / Technical

- Foundational understanding of analog/digital electronic circuit design and PCB layout
- Exposure to USB communication protocols or other high-speed digital interfaces (desirable)
- Basic understanding of power management circuits, battery systems, or BMS/charging circuit principles (desirable)
- Ability to use, or willingness to quickly learn, oscilloscopes, multimeters, and logic analysers for test and fault-finding
