Office Administrator / Customer Success Coordinator

Site Demolition | Sydney, NSW

We’re a growing NSW demolition company looking for an organised, proactive Office Administrator who can also own the customer experience. This role blends everyday admin with customer success — keeping clients informed, supported, and happy from first enquiry through to job completion.

You’ll work closely with the director and operations team, using contemporary tools (including HubSpot) to keep everything running smoothly.

Key responsibilities
Manage incoming enquiries, emails, and phone calls
Coordinate quotes, job scheduling, and client communications
Maintain the CRM (HubSpot) — logging interactions, updating job stages, and following up
Handle customer success touchpoints: progress updates, issue resolution, and post-job follow-ups
Prepare and manage documents, compliance paperwork, and basic invoicing support
Support day-to-day office operations and keep systems organised
Help improve processes using technology and tools

What we’re looking for




Experience in office administration, customer service, or customer success
Comfortable with technology — CRM systems (HubSpot preferred), Microsoft 365, and digital tools
Solid written and verbal communication skills
Highly organised, reliable, and able to juggle multiple tasks
Proactive approach — you spot issues and follow through without being asked
Experience in construction, trades, or a service-based business is a plus (not essential)

Nice to have
Previous customer success or account management experience
Familiarity with HubSpot, quoting systems, or project management tools
Knowledge of NSW construction compliance or demolition processes

What we offer
Direct involvement in a growing business
Opportunity to shape systems and processes
Supportive, no-nonsense team

If you’re organised, tech-comfortable, and positive with people, we’d like to hear from you.
