  • Support innovation and continuous improvement in design and delivery

What you'll bring

  • A degree in civil or geotechnical engineering
  • 12–16 years of post-graduate experience in geotechnical engineering
  • Chartered Professional Engineer (CPEng) status
  • Auckland Council Producer Statement Author (PS1) accreditation
  • Software requirements include knowledge and experience in Plaxis, Rocscience / Geostudio suites for modelling and analysis.

  • Strong project management and client engagement skills
  • A collaborative mindset and commitment to mentoring others
  • A passion for delivering high-quality, community-focused outcomes
