Senior Contracts Specialist

2 weeks ago


Perth, Western Australia Piper Preston Pty Ltd Full time $90,000 - $120,000 per year

SO4 is entering a transformational phase:

Restart → First Commercial Product → Nameplate Production.

At the heart of it all is our Lake Way Project, 15km south of Wiluna—Western Australia's first high-grade Sulphate of Potash (SOP) project with a clean, green, and sustainable focus.

We're a fast-moving, Perth-based mining company, and we're looking for driven professionals ready to make a real impact.

THE ROLE – Make an Impact

Are you detail-driven, commercially sharp, and confident navigating complex contracts? Got a strong grasp of the legal ins and outs of contractual agreements—or even a legal background?

As our Senior Contracts Specialist, you'll report to the Contracts Manager and play a key role in our transition into steady-state operations. Based in our premium Perth office, you'll be responsible for:

  • Supporting key contract activities across the business as we move into production and tackle ad hoc projects.
  • Assisting multiple departments with procurement, commercial advice, contracts for equipment and construction.
  • Managing contracts through pre-award and execution phases—tendering, awarding, and overseeing service agreements across operational and project scopes.
What You Bring

We're after someone who combines commercial acumen with problem-solving confidence and sharp attention to detail.

You'll ideally have:

  • 5+ years of contracts-related experience, with 3–5 years in mining, construction, or agriculture.
  • A strong understanding of contractual and legal frameworks.
  • Background in procurement, tendering, and supplier performance management.
  • Degree in Business, Law, Engineering, Finance, or Supply Chain.
  • Experience in start-up or operational mining environments.
  • Proficiency in Office 365, Pronto, Aconex, and INX.

And you'll thrive if you:

  • Think ahead and tackle problems before they escalate.
  • Communicate clearly and influence effectively.
  • Lead with a hands-on, mentoring approach.
  • Work well under pressure and to tight deadlines.
  • Are passionate about continuous improvement and safety culture.
Why Join SO4?

We're building more than a mine—we're building a legacy of sustainability and opportunity. At SO4, collaboration, innovation, and inclusion are more than just buzzwords—they're how we get things done.

We offer:

  • Competitive salary + Short-Term Incentive Program (STIP)
  • 8 weeks paid parental leave
  • Salary sacrificing & novated leasing options
  • EAP & wellness platform access
  • Perth CBD office with Swan River views
  • Real opportunity to shape a growing business
