The posting

Adservio Luxembourg Adservio Luxembourg is the Luxembourg arm of Adservio Group, 300+ consultants across Paris, Brussels and Luxembourg, and 15 years serving regulated industries as a group. Our Luxembourg office opened in 2022 and works 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 financial institution in Luxembourg that is moving its core applications to an event-driven, cloud-native architecture, while its established integration and batch layers stay in service. Under DORA, operational resilience sits under direct supervisory scrutiny: every service you ship has to be observable, recoverable and auditable.

Your mission You build the services that let your client evolve its applications quickly without trading away reliability.

Build the services

  • You design and develop microservices from specification to production, and own their quality through unit tests and peer review.
  • You implement the event flows and the read and write models behind them.

Keep data fast and consistent

  • You tune queries and stored procedures for performance under production load.
  • You design the document stores that sit alongside the relational core.

Ship and run

  • You automate build, test and deployment through the team’s pipelines.
  • You diagnose production issues across services, integration layers and scheduled jobs.
  • You work in Scrum with product, QA and operations, and adjust as priorities shift.

Your profile You have built and run distributed systems in production, not only read about them.

What is essential

  • Strong C# expertise on .NET Core and .NET Framework, with unit testing built into the way you code.
  • Microservices delivered in production on Microsoft Azure (mandatory), containerised and released through CI/CD pipelines in Azure DevOps, with Git.
  • Hands-on Event Sourcing, CQRS and event-driven architecture with Azure Event Hub or Kafka.
  • Advanced SQL Server (performance tuning, stored procedures) and a NoSQL store such as Azure Cosmos DB.
  • Strong problem-solving and debugging skills, and practice of Agile/Scrum delivery.

What makes the difference

  • Elastic Stack (Elasticsearch, Kibana, Logstash) or a similar observability suite.
  • IBM Integration Bus or a similar enterprise service bus, and an enterprise scheduler such as Automic.
  • Knowledge of the banking sector.

Languages Required: fluent English, written and spoken.

What you’ll find with us A tribe of senior peers. You join our development tribe: senior engineers, peer code 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. This assignment is anchored in financial services, but our engineering work runs across energy, transport, insurance and the public sector, and resilience patterns travel. 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. Our grade framework is explicit, with 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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
