The context
With our team, you work for a leading European payment infrastructure provider, on a 6 to 12-month assignment. Its Finance function wants a tailor-made analytics capability, built on transactional data, to steer the performance of the business.

You give Finance the tools to understand and drive the profitability of the business, built to last beyond your assignment.

Partner with Finance and the business

What you’ll find with us
A tribe of senior peers. You join our data & AI tribe: peer reviews and shared technology watch.
Expertise as a recognised status. Our Subject Matter Experts are called on by fellow consultants and by clients across the group.
Regulated environments, across sectors. This assignment is anchored in payments; our data and AI work runs across energy, transport, insurance and the public sector. You will not stay a single-sector consultant.
A practice still being built, with a clear path. Our Luxembourg office opened in 2022 and is taking shape now, backed by a group of 300+ consultants. What you help put in place becomes the way we work, and our grade framework includes an expert track for those who choose depth over management.

How we hire
Application → Conversation with HR → Technical interview with your future peers → Feedback and decision. Whatever the outcome, you will hear back from us.
