Green Civil Australia is looking for an experienced Senior Civil Estimator to take a lead role in shaping the pipeline of work that drives our business forward.
This is a high-impact, Sydney-based position for a commercially astute estimator ready to move beyond supporting tenders to owning them — from first principles through to contract award.
You'll bring deep technical expertise, sharp commercial judgement, and the confidence to lead complex, high-value tenders with minimal oversight, backed by genuine autonomy and a strong pipeline of civil and infrastructure work.
About the Role
Reporting to the Estimating Manager / Pre-Contracts Manager, you'll take ownership of the full estimating process for complex civil and infrastructure projects — from tender strategy and pricing through to submission, negotiation, and handover — while mentoring junior estimators and contributing to the commercial direction of the business.
Key Responsibilities
Lead full tender processes for complex, high-value civil and infrastructure projects, from go/no-go through to final submission
Develop tender strategy and win themes alongside senior management
Own detailed quantity take-offs, first-principles pricing, and cost benchmarking
Interpret complex tender documentation, identifying commercial risks and opportunities
Negotiate directly with subcontractors and suppliers on major packages
Drive value engineering to improve constructability and strengthen submissions
Manage commercial and contractual risk throughout the tender lifecycle
Engage directly with clients, principal contractors, and project stakeholders as the senior estimating representative




Mentor and develop junior and intermediate estimators
Oversee handover to delivery teams, ensuring commercial intent is clearly communicated
Skills & Experience
Minimum 10 years' experience in civil construction or infrastructure estimating, including leadership of complex, high-value tenders
Degree or diploma in Civil Engineering, Construction Management, Quantity Surveying, or related discipline
Proven track record winning large-scale, multi-million dollar civil and infrastructure projects
Robust commercial acumen and risk awareness across the tender lifecycle
Advanced proficiency in estimating software (Cubit, CostX, Candy, Benchmark, Expert Estimation or similar)
Demonstrated experience leading and mentoring estimating staff
Sound knowledge of Australian Standards and standard contract forms (AS****, AS****, GC21)
Experience in defence, data centre, renewable energy, or complex infrastructure sectors
Exposure to alliance, ECI, or design-and-construct delivery models
Current driver's licence
Typical Projects
Bulk earthworks, major road and pavement construction, stormwater and drainage infrastructure, concrete structures, retaining walls, demolition and remediation, utilities infrastructure, industrial developments, data centres, defence infrastructure, renewable energy projects, and large-scale land subdivisions.
What We Offer
A genuine leadership role with real autonomy and commercial influence, a secure pipeline of large-scale civil and infrastructure projects, a competitive senior-level remuneration package, and a collaborative team culture with clear progression opportunities.
