About Modular Data
Modular Data is a UK data and AI business working with central government and the wider public sector. We are both a consultancy and a technology provider. We advise clients on how to use their data, and we build and run the platforms and tools that deliver it.
We are a small, delivery-focused company, so roles here are broad and people run their own area. Our delivery capability is built from a mix of permanent staff and specialist contractors deployed onto client engagements.
Purpose of the roleThe Customer Success Manager is Modular Data's centralised point of contact for the client. Every client conversation runs through this role, so the relationship sits in one place and the delivery team can concentrate on the work.
The Customer Success Manager leads the client relationship. That means chairing client checkpoints, reviews and governance, setting the agenda for them and driving the resulting actions to closure. Delivery colleagues are brought in where their detail is needed, and are not otherwise involved in client management.
Managing the client means managing delivery. The account cannot be healthy and the client cannot be satisfied unless the work lands on time and to standard, so the Customer Success Manager directs the delivery team on the account: setting priorities, holding people to what was committed, and dealing with problems before they reach the client.
The role is also responsible for growing the account, and being in every client conversation is what makes that possible. The next piece of work is usually visible in a checkpoint long before it reaches open procurement.
This is not a new business role. The work is with the clients we already have.
