Interim Data Consultant = £550-650 Per Day
We’re partnering with a high-growth fintech scale-up that is redefining how data drives financial decision-making. combining a modern data stack with AI-powered workflows (including Claude Code) to radically speed up how analytics and dashboards are built and iterated.
They’re now looking for an Interim Data Consultant who uses AI as part of their day-to-day toolkit to build better dashboards faster, improve data models, and shorten the path from question to insight.
This is not a traditional Data Analyst role or a pure Data Engineering role. It’s a hands-on position sitting between BI, Analytics, AI and Engineering where you’ll own the full journey from pipeline and data model through to high-impact dashboards and decision-ready outputs for commercial, finance and portfolio analytics teams.
The Role
You will:
You’ll be embedded in a commercial, delivery-focused environment where your work is directly tied to how fast the business can understand portfolio and financial performance and make decisions.
What They’re Looking For
They want a rounded interim data consultant, with strong visualisation experience but not someone who lives only in the dashboards or in backend pipelines.
If you’re the person who likes to shape the data model, tune the pipeline, and craft the dashboard so it all hangs together, this is the role for you. It can also be temp-to-perm for the right candidate.
The Stack
