Why Join Master Trade Services?

We’re a fast-growing mechanical services and air conditioning company based in Carrum Downs, delivering top-quality work across residential and commercial projects across Melbourne.

We’re looking for someone exceptional to take charge of our office operations. You’ll be the go-to person, making sure every job runs smoothly, every document is handled professionally, and every customer experience is on point.

This role isn’t for someone looking to learn the ropes. It’s for someone who knows how a trade-based office should run — and thrives on keeping everything organised, accurate, and ahead of schedule.

What You Get in Return:

  • Three weeks guaranteed off over Christmas

  • A paid day off on your birthday

  • A long-term, stable position with room to grow

  • Supportive team and a genuinely great boss (Beau’s known for being a ‘good bugger’)

  • Beers, BBQs and a workplace where a good sense of humour is essential

🧰 What You’ll Be Doing:

  • Running day-to-day office operations and supporting the Director

  • Answering phones, handling enquiries and managing communication across email, socials & CRM

  • Creating jobs and maintaining job data in ServiceM8

  • Issuing work orders and purchase orders for subcontractors and major equipment

  • Coordinating inductions, compliance certificates, VBA, VEU, Solar Victoria admin and builder portal uploads

  • Preparing SWMS, reports, quotes, formatted documents and other key job-related paperwork

  • Assisting with marketing activities including social posts, mailing lists, and database updates

  • Supporting accounts: invoicing, accounts receivable, and payroll via Xero

  • Organising internal folders, job files (SharePoint) and maintaining high admin standards

  • Managing virtual assistants if required

  • Attending team meetings, preparing reports, and supporting project managers

  • Building an admin manual with Loom videos and step-by-step processes as you go

✅ You Must Have:

  • Experience in a trades, construction, mechanical services, or air conditioning business

  • Proven experience with Xero – non-negotiable

  • 2–3+ years’ experience in a similar office manager/admin role

  • Experience with job scheduling and project coordination

  • Strong phone manner and written communication skills

  • A proactive mindset with strong organisational and time management skills

  • Confidence handling compliance documentation and reporting

  • Solid Microsoft Office 365 skills (Word, Excel, Outlook)

  • Ability to prioritise, take initiative, and manage your own workload

Experience with ServiceM8, Procore or other job management systems is highly regarded.

🚫 Please Don’t Apply If:

  • You’ve never worked in a trade, construction, mechanical or air conditioning business

  • You don’t have hands-on experience using Xero

  • You’re not confident answering phones or managing day-to-day admin at a high level

  • You’re looking to “give it a crack” – this role is for someone ready to lead and own the role
