Who we're looking for:

Our people are united by a common belief: that we can outperform in everything we do.

We're currently seeking a highly experienced Estimator (Senior) to join our dynamic New Business team. Based in our new highly appointed and conveniently located Perth office, this role is pivotal in shaping the commercial success of our projects from the ground up. You'll be working in a respected position, across high-profile, large-scale construction tenders, collaborating with internal and external stakeholders to deliver accurate, competitive and strategic cost planning outcomes.

As an Estimator (Senior), you won't just be pricing projects — you'll be influencing design, guiding strategy, broadening professional relationships, mentoring junior staff, and meaningfully contributing to securing exciting new opportunities for the business. If you're looking for a role where your expertise drives real impact and your voice is valued in every stage of the tender lifecycle, this is it.

On a day-to-day basis, you will:

• Lead the preparation of detailed and competitive tender estimates, budgets, cost plans and take-offs.
• Collaborate with design teams, clients and delivery teams to ensure alignment across all project phases.
• Identify and manage cost-specific risks, opportunities and value management strategies.
• Finalise subcontractor and supplier tender lists, RFQs and quotation vetting.
• Prepare and review Bills of Quantities and cost plans from both internal and external sources.
• Support bid strategy development and contribute to "point of difference" tender approaches.
• Mentor junior staff and foster a collaborative, high-performance team culture.
• Provide cost advice and feasibility support to internal stakeholders and clients.

What you'll bring to the team:

• A minimum of 10 years' experience in estimating or quantity surveying within the local construction market. 
• Tertiary qualifications in Construction Management, Quantity Surveying or Engineering (TAFE Diploma in Building or similar also considered).
• Strong understanding of construction techniques and market conditions.
• Proficiency in estimating software such as CostX, Buildsoft,  and Microsoft Excel, as well as Aconex & EstimateOne.
• Exceptional communication, time management and problem-solving skills.
• Proven ability to ‘think outside the box' and deliver results in high-pressure environments and work both autonomously and collaboratively.

A note on diversity:

Diversity is about celebrating the ways we are all different and appreciating the unique qualities that every employee brings. We invite applications from people of all genders, cultures and walks of life. Research shows that women and people from underrepresented groups are less like to apply for roles if they don't meet every qualification. So even if you don't match all the criteria - if you are passionate about helping to construct a better future, we'd love to hear from you.

We are committed to providing a barrier-free work environment and can support with reasonable adjustments at any stage of the recruitment process. Simply inform our Talent Acquisition team during your conversation with them.
