Our ideal Interim HRIS & People Data Lead

Proven experience with HRIS roll-out(s) at 100-500 headcount scale, preferably within in a PE/VC-backed, high-change environment.
We're open-minded which HRIS we will implement, but we know 100% for sure that it will NOT be a massive enterprise solution such as Workday or Oracle, therefore experience implementing a mid-market system such as HiBob, Personio, Cezanne, BambooHR etc. is essential
A strong understanding of People-related Business Process understanding, whilst support from our People Operations team will be there, it's key that you can demonstrate the understanding and experience of scoping and implementing systems that meet business needs - i.e. a 'one size fits all' approach won't work here
Experience with change management, being comfortable with stakeholder engagement, communications and adoption - we are replacing a very much unloved HRIS which has incredibly poor internal PR
We need this person to own the full end-to-end, including the data cleansing and upload
Data and reporting is key for this role, we're looking for evidence you've delivered a dashboard or board pack aimed at executive level and that you're comfortable translating raw HR metrics into insights

Other information

We are open to either a day rate (outside IR35) or FTC engagement
We are expecting our Consultant to be working onsite in London (Fleet Street) 3 days per week (2 days remote)
We ideally are looking for someone to start on 27th October 2025
We have an anticipated timescale of 4 months for this piece of work
