We're a family-owner Australian food manufacturer operating in Thomastown for over 80 years.
We are running IoT hardware that automates production and labour reporting. The system was built by an external consultant who has limited day-to-day availability, so we need a technically strong local technician on a casual, as-needed basis to help keep it running: diagnosing faults and getting reporting back online when something breaks.
About the Role
- Diagnose and repair faults across IoT sensors, controllers and single-board devices (Raspberry Pi, ESP32, Arduino class)
- Flash firmware, reconfigure devices, and recover bricked or unresponsive units
- Troubleshoot the data path end to end (sensor to device to network to server) and identify where reporting has broken
- Perform network diagnostics and configuration: modems, routers, switches, access points, static IPs, VLANs, PoE, and signal or coverage issues on the floor
- Debug communication protocols (MQTT, Modbus, I2C, SPI, serial) using logs, terminal and packet-level checks
- Attend reactive callouts when a device drops offline or a line stops reporting correctly
- Escalate complex or design-level issues to our external consultant, with clear notes on what's already been tried
- Leave short written notes after each visit covering root cause and what changed
Skills and Experiences
- Strong practical electronics skills: circuit-level fault-finding, reading schematics and datasheets, confident with a multimeter and ideally an oscilloscope
- Hands-on IoT deployment or support experience, not just theory
- Networking fundamentals strong enough to independently isolate a connectivity fault
- Comfort in a Linux command line environment (SSH, logs, systemd, basic config)
- Ability to attend site in Thomastown with your own tools and transport
- Able to give a realistic response time when called, even if not immediate, and stick to it
Nice to have
- Light scripting for device testing and automation (Python or Node.js)
- Experience with MQTT brokers, time series databases or similar telemetry stacks
- Factory or production environment experience, food manufacturing in particular
- Embedded development or firmware experience
- Awareness of GMP and hygiene zoning requirements
What We Offer
This is a casual role with occasional call-outs and work offered as it comes up and paid by the hour at $40-60/hr, based on skills and experience.
