About the team The Mayor’s Infrastructure Coordination Service (ICS) is an innovative, award-winning, multi-disciplinary team that drives better collaboration in the planning and delivery of London’s utility infrastructure. This advertised role will sit within the sub-team responsible for the development and implementation of the SSM: the SuDS through Streetworks Market (SSM) . This is an exciting opportunity to play a leading role in the flagship innovation initiative: the SuDS through Streetworks Market (SSM) . The SSM holds the potential of dramatically increasing SuDS by leveraging planned streetworks. This cross-organisational partnership – delivered in partnership with Thames Water – will put forward a market-led approach based on Nobel prize winning economics that will significantly reduce surface flooding risks and positively move the dial on green infrastructure across the city. Our novel approach sits at the heart of London’s climate resilience agenda, supporting Flood Ready London as one of the London Surface Water Strategy’s key delivery mechanisms. Through the SSM, we are aiming to oversee two initial market rounds, deliver at least 100 projects and ultimately convert 7,000 hectares of impermeable land to SuDS to meet our target of number of properties at risk from a 1‑in‑30‑year storm.

Market rounds will be facilitated by a digital SSM Data and Trading Platform, which are the first points of contact for Buyers/Suppliers with the market. Buyers will use the platforms to submit bids (spatially selecting areas and the price they are willing to pay for a credit) and suppliers will submit areas where they are willing to deliver schemes and the price at which they are willing to do so. You will be responsible for developing and managing these key tools, ensuring they remain regularly updated with high-quality data. This will include processing and analysing both spatial and non-spatial data using data science approaches. This role will also oversee the development of a pan-London SuDS Asset Register, which you will manage. Where relevant, you will be responsible for producing innovative, customised and interactive web mapping applications, tools and platforms to display the data and help programme delivery, whilst also generating relevant data analysis and undertaking essential monitoring & evaluation functions. This role offers a unique opportunity to work on a high-profile programme with significant visibility across City Hall, government and industry. Whether your background is in management of digital and data projects, GIS, infrastructure or a related field, you will be motivated by using data to solve challenging problems, building effective partnerships and delivering tangible outcomes for Londoners.
