Senior Data Engineer ( Microsoft BI Stack)

We are seeking an experienced Backend Engineer to join the IT team at a leading bank, supporting the delivery, maintenance, and enhancement of core systems across various business areas, including operations, compliance, transactions, and client management. This is a 6-month contract role offering an excellent day rate, ideally suited to candidates with experience in regulated environments, financial services, or government/public sector organisations.

In this role, you will be an integral part of the software development lifecycle, working closely with Senior Java Developers, UI/UX teams, and Agile Transformation to architect, build, and deliver greenfield, brownfield, and integration applications. You will be expected to employ best design and development practices, solve technical challenges, and contribute to high-quality system analysis and development. Working in an Agile environment, you will participate in Scrum/Kanban ceremonies, write epics and stories (BDD/Gherkin), and focus on delivery, process improvement, and quality outcomes. You will document solutions effectively, estimate and manage tasks, and collaborate with stakeholders across business, IT security, infrastructure, QA, and management teams, using tools such as Jira, Confluence, and BitBucket.

The ideal candidate will have strong Java expertise (Java 17+), with proven experience in server-side development, design patterns, microservices, RESTful APIs, and SQL databases (DB2, SQL Server, or Postgres). Knowledge of front-end development using React, Node.js, HTML, and CSS is a bonus, alongside experience with Elastic ELK, container platforms (Docker/Kubernetes), and test automation tools like Cucumber or Selenium. We are looking for a developer who thrives on building solutions from scratch, takes ownership, and demonstrates self-motivation, excellent communication skills, and a collaborative approach.

We strongly encourage all qualified candidates to apply, including those from regulated sectors or government/public sector organisations, regardless of whether you meet every requirement. If you are passionate about software engineering in a banking or financial services environment and want to make a tangible impact, we would love to hear from you.
