Electronics Engineer - Humidification Technology

Sydney, AustraliaOn-site

Responsibilities

Develop and verify analog and mixed-signal circuits, including work involving PID controller behaviour, stability, and tuning.
Build embedded and low-level firmware to support lab characterisation, test automation, and prequalification of PCBAs before software integration.
Design for safety, EMC, and isolation, including protective and safety ‑ critical circuits to achieve single ‑ fault safety , considering dielectric strength, leakage current, creepage , and clearance.
Design and execution of laboratory experiments to characterise power consumption, temperature rise, humidity and airflow, using sound experimental technique and Design of Experiments (DoE) to explore multi ‑ factor interactions.
Collaborate across software, systems, and mechanical engineering, while supporting verification, documentation, supplier work, and manufacturing readiness.

What You Bring A bachelor’s degree in Electronics, Electrical, or Mechatronics Engineering. Relevant industry

Experience designing humidification systems.

You will join the Engineering function within the Product Organisation and help create new products, plus improvements to existing ones.
You will work in the Consumer and Growth department as part of a cross-functional humidification technology team.
The role supports innovative solutions for sleep apnoea, COPD, and other chronic diseases that improve millions of lives .
Your work will span component selection , circuit design, compliance testing, prototyping, and supplier management.
You will also help shape humidification technologies across device platforms, with products designed for high-volume manufacturing to the high est standards of quality and safety.
What You’ll Do Design, simulate, prototype, document, and test electronics that meet electrical, thermal, safety, regulatory and reliability requirements .
Select components such as microcontrollers , switching power converters and sensors that meet electrical, thermal, safety, regulatory, and reliability requirements.
Apply first-principles physics to electronics design across heaters, sensors, and electrical, thermal, and fluid interactions.
Specification and design of interconnects, including wiring looms, flex circuits and connectors, with appropriate electrical , thermal and mechanical ratings.
Documentation in support of product development including design descriptions, DFMEAs, verification protocols, verification reports and electrical manufacturing specifications.
