Overview of project/role

At TfL’s Network Performance, we're focused on keeping London moving. Working across one of the world's most complex urban transport networks, we use data, insight and innovative thinking to improve journey time reliability, reduce congestion and support better outcomes for everyone who travels around the capital. From enhancing bus priority and optimising traffic signals to supporting major programmes such as Superloop, our teams work collaboratively to deliver practical, customer-focused improvements that make a real difference to millions of journeys every day.

TfL’s Network Performance team is bridging the gap between complex transport analytics and high-impact stakeholder communication. We sit at the intersection of traffic engineering, data science, and interactive visual media.

We are looking for a Senior Transport Visualisation & Data Developer—a hybrid role for someone who understands traffic modelling methodologies and possesses the technical skills to transform heavy datasets into compelling, interactive visual stories.

Whether you are building 3D game-engine simulations of new road layouts, developing interactive R Shiny dashboards for decision-makers, or scripting custom data pipelines to streamline Vissim/Visum outputs, your work will directly influence major London transport initiatives like Superloop and signal optimisation programs.

You'll also play a key role in driving innovation, continually exploring new tools, technologies and techniques to enhance the way TfL visualises and communicates data, modelling outputs and network performance insights.

Key Accountabilities

• Technical Visualisation: Design and build high-quality 2D/3D visual assets, interactive dashboards (e.g., R Shiny), and game engine environments (Unity) to explain complex transport concepts to non-technical stakeholders
• Data & Modelling Integration: Develop custom scripts and automation tools to process, clean, and convert large traffic modelling outputs into visual pipelines
• Cinematic & Spatial Content: Create accurate 3D animations, flythroughs, and visual assets representing proposed engineering and traffic schemes for public consultations, broadcast, and executive briefings
• Process Optimisation: Collaborate with Transport Modellers to build custom tools and workflows that improve the speed, accuracy, and presentation of traffic models
• Stakeholder Engagement: Translate detailed transport analysis insights into clear, persuasive visual narratives for decision-makers and the public
• Standards & Innovation: Drive technical best practices across the team by exploring emerging visual technologies, real-time rendering tools, and data analytics frameworks.
