Senior Data Developer
About The Position
We are looking for an experienced data developer to support a new analytics platform in production and contribute to its upcoming release within a large financial services organization. The solution integrates data from multiple systems in an Azure cloud environment and makes it available through a data warehouse using Power BI. The project is progressing in iterations, each delivering value to users, until the planned handover to the operations team in summer 2027. You will be central to the stability and evolution of the solution: providing technical support after production releases, monitoring the platform, resolving issues with the team, developing ETL processes, and configuring data ingestion pipelines from source systems to data lakes. You will participate in data valuation and the configuration of the data warehouse according to the established model, perform unit testing, and document the processes. The client is seeking a data developer with 8+ years of experience to initially provide production support for the Group Insurance Data Hub, while continuing to contribute to Release 2. The core of the role is data engineering on the Azure stack: data ingestion into data lakes, dimensional modeling (dimensions and facts), and data exposure using Power BI. The recurring keywords (ETL, ingestion pipelines, Data Factory, Synapse, unit testing, continuous integration) indicate that the ideal candidate will write and debug processing code, not be a Power BI report writer or functional analyst. The production support context requires someone capable of independently diagnosing and resolving anomalies within a standardized process environment. This is neither an architect nor a project management role; therefore, candidates with primarily strategic or decision-making experience should be excluded.
Requirements
- 8+ years of hands-on experience as a developer in a large enterprise
- Excellent ETL knowledge and ETL development skills
- Source system to data lake ingestion pipelines

- Domain-Driven Design (DDD)
- Application resilience and event-driven architecture
- Security principles and protocols (SSO, Auth0, SAML, OpenID, JWT, OAuth2, ABAC, RBAC)
Nice To Haves
