Welcome to Transport Systems Catapult

There is a global race to provide better transport solutions.  Clean, green, safe, easy to access, convenient, whole-journey solutions are the future.  Informed, digitally connected, passengers demand a better service and the country’s economic future depends on us having a much more intelligent approach. The revolution in data science and connectivity, along with UK’s world leading research base as well as our transport industry’s pedigree provides the UK with the opportunity to win this race.

The Transport Systems Catapult (TSC) is a neutral, not-for-profit, Technology and Innovation company full of energetic, capable, technologists and business experts undertaking applied research projects in collaboration with academia, SMEs and industry with the aim of making UK a world leader in transport innovation. Current ‘initiative areas’ include Connected and Autonomous Transport, Mobility-as-a-Service Platforms, Open Transport Data Hub, SME and Scale-up Partnerships and Academic Alliances.  It’s novel, it’s exciting, it’s challenging and it’s a rapidly growing market…… All aboard please!

We work with companies, universities and government using technology and novel commercial models to transform transport.  We call this ‘Intelligent Mobility’.  Intelligent Mobility is the smarter, greener, safer and more efficient movement of people, goods and information around the world. We work to identify future technology trends, so we can make the UK a global leader and create jobs and grow companies.  Through identifying new technologies and ways of working, we are making transport better for everyone.

We are looking for individuals who have the ambition and drive to want to make a difference and be part of defining the future of transport.  You will have the opportunity to become involved in and help to shape and deliver unique and ground-breaking projects at the cutting edge of transport innovation.

Technical Capability Teams

The delivery arm of the Catapult comprises several capability teams organised into technical areas.  Individuals of similar or aligned skillsets are grouped into teams though are able and encouraged to contribute to virtual project teams under a project manager.  We have transport, 3D and environmental modellers, economists and business analysts, data scientists and AI specialists, software developers and big data engineers, systems engineers and drone experts, social researchers and anthropologists……. and we have plans to grow more.

Role overview

This role will support our ongoing programmes of work in relation to new mobility services, connected (and autonomous) vehicles, and advanced modelling techniques.  Reporting to the Modelling and Visualisation Team Leader, you will be responsible for leading the development of innovative new multi-modal modelling tools and platforms to enable the potential demand for and impact of future mobility services to be assessed and appraised. This is likely to include the use of conventional modelling packages as well as innovative new platforms that will be developed within the team.  Key focus areas of this role will be in the development of demand models to assess the likely uptake of mobility services as well as developing models to enable the multi-modal impacts of such new services to be understood. Due to a significant project win we are particularly seeking candidates with experience of TfL’s strategic modelling suite, LTS, LoHAM and Railplan.

Your input will define the technical scope of the project work that we will be undertaking with partners and stakeholders.  You will also provide technical direction, leadership and assurance throughout the project delivery phase, providing clear support and direction to the team undertaking the technical work and ongoing engagement and liaison with project partners and stakeholders.  You will often be developing projects from first principles for ‘First of a Kind’ feasibility studies or demonstrators.  This often requires working through ambiguity to identify a clear project scope – you will need to be comfortable with this exciting, challenging and essential part of this role.

The role is likely to cover the full range of activities that the TSC is engaged with, including connected and autonomous systems, new mobility services and data sharing/analytics. You will have strong industry reputation and credibility and been seen as a thought leader.

A key facet of this role will be taking learning and experience gained from developing and operating current models and applying that for unconventional and innovative uses.  Having an eye for innovation and seeing how modelling could be done in different ways is a key requirement for this role.  You will also be expected to contribute to the dissemination of our project results via attendance at major UK and international conferences and seminars.
