At Jacobs, we're challenging today to reinvent tomorrow by solving the world's most critical problems for thriving cities, resilient environments, mission-critical outcomes, operational advancement, scientific discovery and cutting-edge manufacturing, turning abstract ideas into realities that transform the world for good.

Your impact

You are an experienced traffic or transport engineer with a passion for creating safer, more sustainable and better‑designed streets and places. You bring strong technical expertise, sound professional judgement and a practical, solutions‑focused mindset to complex urban transport challenges.

You enjoy working collaboratively within multi‑disciplinary teams and engaging constructively with clients and stakeholders. Whether developing active travel schemes, re‑allocating road space, or shaping high‑quality urban streets, you are motivated by delivering designs that respond to their context and make a tangible difference to communities.

You take pride in the quality of your work, are confident working across all project stages, and enjoy mentoring others while continuing to develop your own technical leadership.

About the Opportunity

Our business unit brings together engineers, architects, surveyors, urban designers, project managers and transport planners. By working collaboratively across disciplines, we deliver clear, considered and implementable design solutions for clients in Ireland, the UK and internationally.

We are seeking an experienced professional to join our Active Travel & Urban Transport team, working on a hybrid basis from our Dublin office and client locations.

Producing and reviewing high‑quality designs, drawings, reports and tender documentation
Applying Irish design standards and guidance to develop practical, context‑led solutions
Supporting project and client management, including programme, resources, quality and commercial performance
Engaging effectively with clients, local authorities and stakeholders
Checking and reviewing deliverables, ensuring design consistency and technical assurance
Mentoring and supporting junior team members and contributing to a collaborative team culture
Supporting business development activities, bid preparation and client engagement

Here's what you'll need

Strong technical background in traffic engineering, including:
- Junction and road link analysis and modelling
- Traffic signals design
- Road markings and traffic sign design
- Pavement, drainage and utilities design
- Preparation of tender documents and works specifications
Experience in urban streets, active travel, bus priority, public transport and/or public realm schemes
In‑depth knowledge of key Irish standards and frameworks, including DMURS, Cycle Design Manual, Capital Works Management Framework, Transport Appraisal Framework and NTA Project Approval Guidelines, together with knowledge of relevant TII standards and sustainable transport policy
Proven experience delivering projects through all design stages, from concept to detailed design and delivery support, including site supervision
Strong written and verbal communication skills, with the ability to clearly explain complex issues to a range of audiences
Experience in project and client management, including programme, resourcing, commercial performance and quality control
Ability to manage workload effectively while mentoring junior staff and contributing to team development
Experience contributing to bids, client engagement and awareness of emerging trends and best practice
A clear commitment to knowledge sharing, staff development and technical leadership
