Ready to do work that actually excites you?

We are looking for a 12D Designer to produce civil design models and service drawings, with a focus on stormwater management and drainage infrastructure. The ideal candidate for this role should have mid-level experience in 12D modelling and drawing production, along with a working understanding of flood analysis, detention design, and underground pipe network design. This role is critical for delivering accurate, code-compliant design models and documentation that keep large-scale development projects on schedule.

What You’ll Do

• Create and maintain 12D models for civil and stormwater design, ensuring accuracy and compliance with applicable standards
  
• Produce detailed service drawings from design models, including drainage and stormwater infrastructure layouts
  
• Design stormwater detention systems in line with project requirements and stormwater management plans
  
• Assist in the modelling and documentation of underground drainage networks using established design parameters.
  
• Carry out flooding and overland flow analysis using hydraulic and hydrological modelling tools
  
• Prepare and update design inputs for stormwater management plans
  
• Run drainage and hydraulic modelling in software such as DRAINS and HEC-RAS, and support storm simulation modelling where required
  
• Coordinate with design engineers and project team members to align models and drawings with design intent and project deadlines
  
• Manage multiple modelling and drawing deliverables across large, high-volume development projects while meeting tight timeframes
  
• Apply structured processes and QA checks to ensure model integrity, drawing consistency, and documentation accuracy
  
• Identify opportunities to improve efficiency in design workflows, including the use of automation and AI-assisted tools
  

Requirements

What You Bring
