Residential Sales & Project Consultant - Septic Systems Australia
Are you someone who enjoys working with people, solving problems and being out on the road?
Maybe you're a plumber looking for a career beyond the tools. Maybe you're working in trade sales, construction or building supplies and want to take the next step into a customer-facing role with more autonomy and opportunity.
If you're commercially minded, practical, and enjoy building relationships, we'd love to hear from you.
About us
Septic Systems Australia is a leading provider of residential wastewater treatment systems.
For more than 20 years, we've helped homeowners, builders, plumbers and developers deliver compliant, reliable and environmentally responsible wastewater solutions.
As part of a broader group that includes Harmor Liquid Waste Solutions and Yarra Valley Septics, we're proud to play an important role in protecting communities and waterways across Australia.
The opportunity
This is a unique role that combines sales, customer consultation, site assessments and project coordination.
You'll manage residential installation opportunities from initial enquiry through to project approval, helping customers navigate what can often be a complex process while ensuring they receive the right solution for their property.
Success in this role comes from building trust, creating opportunities and delivering a excellent customer experience.
One day you might be helping a family build their dream home. The next, you could be working with a plumber, volume or independent builder, architect or developer to deliver a practical wastewater solution.
You'll be responsible for:
Meeting customers and conducting site inspections
Understanding customer needs and project requirements
Assessing site suitability and installation feasibility
Preparing quotations and recommendations
Following up opportunities and converting sales
Building relationships with plumbers, builders and referral partners
Generating new business opportunities




Managing your sales pipeline and customer relationships
Coordinating accurate project handovers to our installation team
Where you'll be based
When you're not visiting customers or conducting site inspections, you'll be based from our Kilsyth office and yard, working alongside our experienced service, operations and installation teams.
You'll have the opportunity to learn from industry experts while remaining closely connected to project delivery and customer outcomes.
Who we're looking for
We're not necessarily looking for wastewater experience. We're looking for the right person.
You may come from a plumbing, trade sales, building supplies, construction, civil, environmental services, technical sales, account management or business development background and be looking for an opportunity to take the next step in your career.
Most importantly, you're someone who:
Builds relationships naturally
Communicates confidently with a wide range of people
Is equally comfortable talking to homeowners, plumbers and builders
Enjoys being out in the field rather than behind a desk
Takes ownership of outcomes
Is organised and follows through on commitments
Wants to develop a long-term career in sales and project consulting
What's on offer
Established and respected Victorian business
Strong pipeline of incoming enquiries
Company vehicle, phone and laptop provided
Competitive salary plus performance incentives
Ongoing training and development
Supportive and experienced team environment
A balance of field-based work and office collaboration
Genuine career growth opportunities
And some cool perks like an extra day off on your birthday
Why this role is different
This isn't a high-pressure sales role. It's about understanding customer needs, building trusted relationships and helping people find the right solution. We're looking for a trade-smart relationship builder who enjoys meeting people, solving problems and seeing projects through from first conversation to successful delivery.
If that sounds like you, we'd love to hear from you.
