Your responsibilities will span from data integrations, processing, validations and visualisation utilizing Data Lakehouse with medallion architecture, Reporting Suite and conversational LLM models. You will guard the data consistency, quality and end to end governance from where data is born to where it is used in dashboards, AI / ML applications and other data consumers. You will also be involved in building insightful visualizations and reports used by customers of banks worldwide. In addition you will be involved in design, develop, and deploy scalable AI-driven solutions: underlying infrastructure, agent orchestration layers, and evaluative frameworks that make AI reliable, safe, and impactful in a highly regulated financial environment. You will work in a multinational, diversified, focused and professional environment with a friendly atmosphere. We bring data in, reconcile it into one version people can rely on, and make it available to the right audience. Increasingly that audience is agents as well as people, so everything we build has to work for both. Two things must hold at every step: that only the right people can see it, and that we can prove it is correct. You build the platform that makes both possible. As a Senior Data Engineer you own the foundation: the lakehouse, the pipelines that fill it, and the layers that serve it. We treat data as a product, so each one has a named owner, a documented contract with the teams who consume it, and stated expectations on freshness and quality. That includes Data as a Service, where internal and external teams run analytics on data held in our AI-powered Banking OS. This is not only a tabular data job. A large part of it is a versioned documentation corpus, kept current, deduplicated and traceable across many product versions, and much of it arrives semi-structured rather than clean. The consumers are not only dashboards either. You build and maintain the MCP tools that let AI agents query documentation, API specs and release history directly. That is a meaningful part of the role, not a side project. We hold pipelines to the same standard as application code: tested, reviewed, deployed through CI/CD, observable in production, and promoted properly across environments. If that is already how you think about data engineering, you will recognise this team quickly.
