## Description

**Adservio Luxembourg**  
Adservio Luxembourg is the Luxembourg arm of Adservio Group, 300+ consultants across Paris, Brussels and Luxembourg, 15 years serving regulated industries. Opened in 2022, our office works across financial services, energy and utilities, transport and mobility, insurance and the public sector. You join our Technologies & Engineering practice.

**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.

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

_Build the Finance analytics tools_

-   You design and build the data apps and analytical tools of the Finance function.
-   You turn a need expressed by Finance into a durable tool, not a one-off analysis.

_Work on transactional finance data_

-   You exploit transaction data, ledgers and reconciliations.
-   You deliver profitability and customer lifetime value (CLTV) analyses.

_Partner with Finance and the business_

-   You work within the Strategic Finance team, in close contact with cross-functional partners.
-   You help the business steer its performance from the tools you build.

**Your profile**  
_What is essential_

-   At least 5 years in data analytics within a fintech, a payment provider or a finance function.
-   Data apps you have built on transactional data, ledgers, reconciliations, profitability and CLTV.
-   Advanced SQL and data modelling skills.

_What makes the difference_

-   Used to working in an SAP environment (S/4HANA).
-   Alteryx experience.

**Languages**  
Required: English, professional working proficiency.

**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.
