12D Designer

Setup and Location:  WFH
Work Schedule: 9:00 AM to 6:00 PM (ADT) | 6:00 AM to 3:00 PM (PH Time)
Employment Type: Full-time

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
We’re looking for someone who:

• Bachelor’s degree in Civil Engineering or a related field
  
• 4-8+ years of experience in civil design, drainage design, or stormwater modelling, or related experience
  
• Proficiency in 12D (core requirement); Civil 3D experience is desirable as an alternative
  
• Familiarity with DRAINS, or the ability to learn it quickly on the job
  
• Knowledge of general Australian civil engineering codes and standards is required, while experience working on South East Queensland projects is highly regarded
  
• Experience with 2Flow or other storm simulation software, as well as HEC-RAS modelling, is an advantage
  
• Ability to self-learn with guidance, and to follow structured processes and recorded training materials
  
• Forward-thinking mindset toward efficiency, including openness to AI tools and workflow automation
  
• Strong attention to detail and accuracy in modelling and drawing production
  
• Strong time management skills, with the ability to deliver within tight project deadlines
  
• Good written and verbal communication skills for coordinating with engineers and project teams
  

Benefits

What You Bring
We’re looking for someone who:

• HMO, Dental, and Life Insurance for you and one free dependent from day one (with the option to enroll additional dependents)
  
• Paid Leaves: Birthday, Vacation, Medical, and Maternity (up to 6 Vacation Leaves are convertible to cash on your anniversary)
  
• Employee Engagement Activities: Year-End Party, Family Day, Team Building, and more!
