## Description

**Adservio Luxembourg**

Adservio Luxembourg is the Luxembourg arm of Adservio Group, 300+ consultants across Paris, Brussels and Luxembourg, 15 years serving regulated industries. We opened in Luxembourg in 2022 and work across financial services, energy and utilities, transport and mobility, insurance and the public sector: wherever compliance is not optional and failure is not acceptable. You join our Technologies & Engineering team.

**The context**

With our team, you work for a Luxembourg bank on the production of its client documents: statements, advices and regulated correspondence, generated in volume and delivered on paper and digital channels. These documents carry MiFID II client reporting obligations, so content, layout and delivery must be right the first time. The engagement runs for twelve months or more.

**Your mission**

You turn structured client data into documents that are accurate, consistent and delivered on time, whatever the channel.

_Template design and development_

-   Design and develop document templates, from data mapping to final layout
-   Implement business rules: conditional content, multilingual versions, channel-specific output

_Production and delivery_

-   Configure and maintain the composition and output chain for print, PDF and digital channels
-   Monitor production runs and resolve incidents before they reach clients

_Quality and change_

-   Test documents end to end against source data and business specifications
-   Work with business teams and upstream data providers to specify and deliver changes

**Your profile**

You know how data, templates and output streams fit together, and where they break.

_What is essential_

-   At least three years of hands-on experience developing documents on Sefas
-   Solid grounding in document composition: templates, data mapping, print and digital output streams
-   Experience on high-volume client documents in a regulated environment
-   Master's degree in computer science, information systems or a related field

_What makes the difference_

-   Familiarity with output formats such as AFP, PDF and XML
-   Exposure to a core banking data environment
-   Experience in a Luxembourg banking environment

**Languages**

Required: English and French, professional working level · Asset: German

**What you will find with us**

**A tribe of senior peers.** You join our development tribe, with peer reviews and shared technology watch.

**Expertise as a recognised status.** Our Subject Matter Experts are named as such, and are called on by fellow consultants and by clients across the group.

**Regulated environments, across sectors.** Your assignment is anchored in banking, but our 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 build becomes the way we work, and our explicit 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.
