  • Produce high-quality documentation, drawings, and technical reports
  • Coordinate with engineers and multidisciplinary teams to achieve integrated outcomes
  • Ensure designs comply with Australian standards and local authority requirements
  • Provide support during construction, including design clarifications and revisions

SKILLS AND EXPERIENCE. 
  • Proven experience as a Civil Designer with strong 12D   expertise
  • Background in land development projects within Australia
  • Solid understanding of stormwater design, earthworks, and pavement design
  • Experience working with relevant software (e.g. 12d, Civil 3D, DRAINS, MUSIC, TUFLOW or similar)
  • Strong knowledge of local council standards and approval processes
  • Ability to manage multiple projects and meet deadlines
  • Effective communication skills and a collaborative approach

CULTURE. 

You’ll be part of a down-to-earth, high-performing team where knowledge sharing is encouraged and contributions are recognised. The business promotes a healthy work environment with realistic expectations, supportive leadership, and a focus on long-term career development.


BENEFITS. 
  • Competitive salary aligned with experience

  • Flexible working arrangements
  • Exposure to a broad range of projects and clients
  • Supportive and inclusive team environment
  • Access to modern tools and ongoing professional development
