Working for City Hall makes a difference to the lives of Londoners. Our staff are at the centre of long-term planning and development for our great city.
Organisation: Greater London Authority
Job title: SSM Lead
Reference: 5857
Salary: £81,138 per annum
Grade: 12
Contract type: Permanent
Team: Infrastructure Coordination Service
Directorate: Good Growth
Interview date: W/c 9th and 16th November (may be subject to change)
Location: Union Street
Application closing date: 25 October 2026 at 23:59:00
Good Growth
Good Growth is responsible for delivering and implementing the Mayor’s environment, transport and economic strategies and for the effective implementation of the London Plan. The Directorate is also responsible for regeneration (where the programme is not housing led), enterprise, growth, capital projects and design work.
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 this flagship innovation initiative: establishing the UK’s first environmental services market for sustainable drainage systems (SuDS).
The SSM holds the potential to dramatically increase SuDS by leveraging planned streetworks. A cross-organisational partnership – delivered in collaboration 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 number of properties at risk from a 1 in 30 year storm.
About the role
As SSM Lead within the Mayor's Infrastructure Coordination Service, you will lead a new 7-person team to implement the SuDS through Streetworks Market. Working at the intersection of environmental markets, surface water management and infrastructure delivery, you will oversee the successful implementation of the SSM by bringing together key partners to engage in this new delivery mechanism.
You will oversee a number of interdependent workstreams – across stakeholder engagement and comms, SuDS design and streetworks, environmental market economics, governance, monitoring & evaluation, data, among others – to ensure the SSM work programme is delivered successfully and within budget.
This will involve convening ‘buyers’ – lead local flood authorities, Boroughs and Transport for London – together with ‘suppliers’ – utilities and contractors – to develop market and commercial arrangements, technical guidance and best practice, ensuring lessons are learned from each market round and refine the wider SSM processes. The SSM leverages London’s high volume of annual streetworks and encourages contractors to reinstate SuDS rather than traditional asphalt and concrete into their planned streetworks, thereby delivering SuDS at scale, lowering costs of delivery and reducing road disruption.
The role offers a unique opportunity to work on a high-profile programme with significant visibility across City Hall, government and industry. You will engage with senior stakeholders across the GLA and the wider sector – including Flood Ready London, Ofwat, lead local flood authorities and the Environment Agency – to help shape how London's infrastructure networks support the city's growth ambitions.
