At Mayor's Fund for London, we believe every young Londoner should have the opportunity to thrive. To help us achieve that, we're looking for an experienced CRM, Data & Impact Manager to lead the development of our Salesforce CRM, strengthen how we use data across the organisation and help us demonstrate the impact of our work.
This is an exciting opportunity for someone who enjoys improving systems, solving problems and turning data into meaningful insight. As the organisation's lead for Salesforce, you'll play a central role in ensuring our CRM supports colleagues across delivery, partnerships, and engagement.
You'll take ownership of the day-to-day administration, development and continuous improvement of Salesforce, helping colleagues get the very best from the system while identifying opportunities to improve processes, reduce manual administration and strengthen organisational reporting. Whilst specialist external support is available for larger developments, you'll be confident leading routine system improvements, troubleshooting issues and implementing practical CRM solutions independently.
Alongside leading our CRM, you'll champion high-quality data and reporting. You'll work with colleagues across the organisation to improve data quality, develop meaningful dashboards and reports, and ensure information is used to support better decisions, stronger programmes and greater organisational learning.
We're looking for someone who enjoys working collaboratively, building relationships and helping others embrace better ways of working. You'll be equally comfortable discussing system improvements with colleagues, analysing data to identify trends and opportunities, and translating technical information into practical solutions that make a real difference.
This is a role for someone who wants to combine technical expertise with social purpose. If you enjoy making systems work better and want your work to contribute to improving outcomes for young Londoners, we'd love to hear from you.
What you'll bring
You'll have experience leading and improving a CRM system (Salesforce), fixing bugs and issues, developing reporting and dashboards, improving data quality and supporting colleagues to make better use of systems and information. Most importantly, you'll enjoy solving problems, working collaboratively and continuously improving how an organisation uses CRM and data to achieve its mission.
We recognise that no candidate is likely to meet every criterion. If your experience aligns closely with the role and you believe you have the skills and potential to succeed, we'd encourage you to apply.
