• Prepare high‑quality technical reporting and provide clear, defensible interpretation of results for stakeholders and decision makers
• Collaborate with traffic engineers, planners and designers to provide modelling inputs that support design development and business cases
• Coach and review the work of junior modellers/analysts, contributing to capability uplift across the team (where relevant to level)

About You
You will bring:

• Demonstrated experience in traffic/transport modelling in an Australian consulting or client environment
• Hands-on proficiency in one or more of VISSIM, Aimsun, SIDRA (and a willingness to broaden your toolkit)

• A collaborative mindset and confidence engaging with clients and internal stakeholders
• Relevant tertiary qualification (e.g., engineering, transport planning, mathematics/economics or related)
