Senior Contracts Administrator

15/2/2026

We are seeking a Senior Contracts Administrator (minimum 5 years’ experience) to join our Parramatta-based team, working on Creek Connect, a major water infrastructure project for Sydney Water.

In this role, you will administer head contracts and key subcontracts, manage variations and claims, ensure contractual compliance, and support procurement and commercial activities throughout the project lifecycle. You will work closely with project managers and key stakeholders to drive successful outcomes.

This position offers long-term stability and valuable exposure on one of Sydney’s largest and most complex water infrastructure programs.

CreekConnect – Supporting Western Sydney’s Growth!

Be part of a large-scale, long-term joint venture between Seymour Whyte and Jacobs, awarded by Sydney Water as an Engineering, Procurement, and Construction Management (EPCM) project. As the region expands, so does the need for sustainable and resilient water solutions. The Upper South Creek Network will feature new wastewater pumping stations and gravity carriers, with the first work stage beginning before the year's end. The project also emphasises safety, digital engineering, and compliance with the latest standards, ensuring it meets future needs effectively.

About Seymour Whyte:

We are a successful civil contracting business that has been operating in Australia for over 35 years. With the agility and personal connection of a Tier 2, yet the expertise of a Tier 1, and the enhanced resources of one of the largest, world-class construction companies, VINCI, our employees and clients get the best of three worlds.

As a progressive, leading civil engineering firm built on the strong foundations of our unique history, we engage, enable and empower our people to be better. With you, we are altogether stronger, in building the future we want. 

About the Role:

  • Administer head contract compliance and subcontract agreements
  • Oversee tender evaluations and negotiate subcontractor terms
  • Process payments, variations, and ensure statutory compliance
  • Support project team with commercial advice and reporting
  • Maintain financial systems and deliver contract admin training

About you:

  • Tertiary qualifications in Construction Management, Quantity Surveying, or Engineering
  • Min. 5 years of relevant infrastructure experience – Water experience advantageous
  • Excellent written and verbal communications skills
  • Strong knowledge of procurement and financial systems
  • Proficiency in MS Word, Excel, Access, and Outlook
  • Current C-Class Driver’s Licence

Company Benefits:

  • Health & Wellbeing – discounted health insurance, seasonal vaccinations, wellness discounts, fertility benefit and employee assistance program (EAP).
  • Time for life / Work life balance – birthday leave, purchased leave program, paid parental leave and flexible work arrangements.
  • Financial wellbeing – competitive remuneration, annual performance bonuses, salary continuance insurance and employee share program.
  • Career development – training, mentoring programs, and leadership development program.

Many of our projects are not accessible via public transport and require travel between and within active construction sites. As a result, a current Driver’s Licence and the ability to drive on site are essential.

Seymour Whyte is an Equal Opportunity Employer, and we encourage applications from candidates with diverse backgrounds, including veterans. Our commitment to an equitable construction industry extends to an inclusive culture that embraces our differences and gives everyone the opportunity to grow and be equally valued. We're unified in our direction toward having a workplace that is balanced and fair for all.

Warning to applicants about false job offers and fraudulent proposals

The VINCI group wishes to warn applicants about the online publication of false job offers for contracts abroad in the name of VINCI group companies. The authors of these offers fraudulently use the corporate names, brands and logos of VINCI group companies to deceive applicants, inducing them to reveal personal information and to pay money to obtain alleged services. Under no circumstances do VINCI group companies ask for candidates' bank details or any payment of money as part of their recruitment process. We therefore strongly recommend that applicants check the authenticity of job offers before responding to them.
