Be the person who keeps our growing business organised and running smoothly.

Mactech Diesel Solutions is a growing, family-owned diesel workshop specialising in servicing and repairing earthmoving equipment, trucks and diesel machinery.

Having recently moved into a larger workshop to support our continued growth, we’re looking for an experienced Office Coordinator to become a key part of our team and help coordinate the day‑to‑day administration of our business.

You’ll work closely with our small team of mechanics and two working directors, helping keep the workshop organised, customers looked after and the business running efficiently.

This isn’t your typical administration role.

We’re looking for someone who enjoys taking ownership, improving systems, solving problems and making a genuine difference. You’ll have the opportunity to learn how a growing business operates from the ground up, improve processes and help shape the systems and structure that will support Mactech’s continued growth.

Our current Office Manager provides remote support and guidance, while this role will become the trusted day‑to‑day contact in our Rocklea office. You’ll be well supported but trusted to work independently, use your initiative and take ownership of your role.

We’re looking for someone who wants a long‑term career, not just another admin position. As the business grows, this role offers a genuine pathway into an Office Manager position.

Position Details

Location: Rocklea, Brisbane
Employment: Full-time, Monday to Friday
Hours: 8:30am–5:00pm preferred, with flexibility available for the right person (for example 8:00am–4:00pm)
Salary: $65,000–$70,000 + Super (negotiable depending on experience)

Vehicle Requirements:
A reliable vehicle and Queensland driver's licence are required for this role. Initially, you will use your own vehicle for occasional business errands such as collecting parts and supplies when required. Approved business‑related travel expenses will be reimbursed. As the business continues to grow, we plan to introduce a company vehicle for business use.
