Principal Transport Engineer

SLR Consulting is seeking an experienced traffic and transport consultant to join our well-established teams in Brisbane and Sydney. We have an opportunity for a senior practitioner with 8+ years' experience who is ready to lead projects, develop client relationships, and help shape the direction of a growing team.

About SLR Consulting

At SLR Consulting, we are problem solvers, innovators, and trusted advisors helping shape sustainable solutions worldwide. With more than 5,000 people globally and a strong Asia Pacific team of over 1,200, we deliver specialist consulting services to a growing client base across business, regulatory, and government sectors.

At the heart of SLR is a collaborative 'One Team' approach, a supportive and accessible workplace culture, and opportunities to work alongside industry leaders while making a real impact.

About the role

We are looking for a Principal Traffic & Transport Consultant to join our Brisbane and Sydney teams, working flexibly from our water-side offices in both cities. This is a full time position ideally, however we will consider applications from those looking to work part time.

This is a role for someone who has built strong technical credentials and is ready to take on broader leadership responsibilities while staying closely involved in the technical work. You will direct and deliver projects with a high degree of independence, provide technical leadership across the team's work, and play an active role in growing client relationships and pursuing new opportunities.

One of the strengths of working at SLR is the depth of capability around you. Our transport advisory team is part of a broader multi-disciplinary consulting platform, which means you can draw on specialist expertise in areas like planning, environment, and engineering to deliver genuinely integrated advice for your clients.

Your work will span a diverse mix of strategic and site-specific projects for private developers, government agencies, and regulatory bodies across Australia and internationally. Our clients include major retail and commercial property groups, residential developers, local and state government, and infrastructure delivery agencies.

At a Principal level, you will combine hands-on technical contribution with leadership across the team:

• Directing projects from inception through to delivery, with responsibility for scope, program, budget, and quality
• Providing senior review and quality assurance across the team's outputs
• Acting as a trusted advisor to clients and regulatory authorities, including representing SLR at stakeholder forums, council meetings, and agency briefings
• Growing and maintaining client relationships, and identifying opportunities to extend the work we do for existing clients or open doors with new ones
• Leading the preparation of fee proposals and tender submissions
• Mentoring and developing junior and mid-level team members, building capability across the team
• Working closely with other discipline leads within SLR to bring multi-disciplinary solutions to complex projects

You will bring depth of experience across one or more of the following areas, and an ability to lead project teams delivering work across the others:

• Traffic engineering, design, and road safety
• Transport modelling and network analysis, from intersection-level through to corridor and strategic assessments
• Traffic impact assessment and development-related transport advisory
• Transport planning across active, public, and freight modes
• Construction traffic management
• Expert witness and tribunal advice

Breadth of experience is valued, but so is depth. If you have built a strong career across a subset of these areas and are looking to take on a broader role, we encourage you to apply.

Qualifications

We're looking for someone with:

• A degree in Civil Engineering, Transport Planning, or a related field
• 8+ years of experience in traffic engineering, transport planning, or a related consulting discipline
• A track record of independently managing and delivering projects to successful outcomes
• Recognised expertise in your field, with a reputation for sound, practical advice
• Experience mentoring and developing less experienced staff
• Confidence engaging with senior stakeholders across private and government sectors
• A genuine interest in business development and growing the work of the team
• Proficiency with relevant industry tools such as SIDRA, AIMSUN, VISSIM, AutoTurn, or similar
• Working knowledge of Australian transport planning frameworks, guidelines, and approval processes
• Chartered or working towards chartership with Engineers Australia, or equivalent professional recognition

Benefits

At SLR, we know that every person is different, which is why we offer a benefits package designed to support both your personal and professional growth:

• Hybrid work model – Enjoy the balance of in-office collaboration and work-from-home flexibility
• Extra paid leave – Purchase up to 10 additional leave days for personal or professional development, volunteering, or family time
