Lead Business Intelligence Developer

“Be the Architect of Our BI Future”

At Castle Trust Bank we pride ourselves in being a fintech challenger bank, providing specialist property mortgages, retail finance lending and savings accounts to a variety of customers.

We’re modernising our data landscape — and we’re looking for a Lead Business Intelligence Developer who wants to shape the future of reporting, modelling, and data governance in a growing fintech environment.

What you’ll lead and deliver:

In this role, you will own the data model design and delivery of high-quality reporting solutions, shaping the strategic direction of business intelligence across the Bank.  You'll take pride in delivering high-quality reporting solutions using your core toolkits: Power BI, DAX for models and visualisation and SQL for data extracts. Experience with Microsoft Fabric is desirable as this is on our short-term roadmap. Improving data governance and reporting standards will be central to your impact.

Data model design will be one of your core competencies, and you’ll enjoy working with business analysts and stakeholders to translate source data and reporting needs into elegant models and insights. You’ll be skilled at stakeholder management and prioritisation, ensuring clear plans and timely delivery.

You'll lead a team of two Business Intelligence Analysts, driving a culture of technical excellence and personal development within the team.

You will have a passion for innovation, fascination with new technologies, and you'll be excited to champion them to generate business benefits.

You will play a pivotal role in helping Castle Trust become a more data‑empowered organisation — and you’ll shape the tools, processes, and habits that get us there.

This is a hybrid role based in Basingstoke, with flexibility to work 2 days from home per week.

What you’ll bring:
