Business Intelligence Specialist - BI Specialist

Data & Functions Technology Delivery provides data products that help colleagues across the Society make informed decisions. We are looking for a Business Intelligence (BI) Specialist to design, build and enhance trusted reporting and insight solutions that turn business questions into clear, actionable information.

This is a hands-on BI Specialist role. You will take ownership of defined BI deliverables, working independently within agreed standards while collaborating with business stakeholders, BI colleagues and data engineers. You will be expected to apply sound judgement, manage competing priorities and contribute your expertise to the wider BI community.

At Nationwide we offer hybrid working wherever possible. More rewarding relationships are supported through our hybrid approach, bringing colleagues together across our UK wide estate, whilst also supporting generous access to home working. We value our time in the office to solve problems, to learn, and to feel connected.

For this job, you'll spend at least two days per week, or if part-time, you'll spend 40% of your working time, based at our Swindon, London or Glasgow office. If you’re based at our Glasgow office, this will apply from 1 April 2027 and ahead of that there will be a need to regularly connect with colleagues for collaboration events. If your application is successful, your hiring manager will provide further details on how this works.

You can also find out more about our approach to hybrid working here.

Whilst these locations are where we are primarily looking to fill the role, if you’re an internal applicant based in a different location, we would welcome your application and, if successful, your hiring manager will provide further details on how this could work for this specific role.

Nationwide is committed to the redeployment of our employees impacted by change, as such applications for redeployment candidates will be prioritised in this recruitment process.

If you’re a colleague on long-term absence (for example, on parental leave) or a temporary worker, please use your personal email address to submit an application.

What you’ll be doing

As a BI Specialist, you'll design, develop, test and maintain Metric Views, Power BI reports, dashboards and semantic models that meet agreed user needs and deliver meaningful insight. Working closely with stakeholders across the business, you'll take time to understand key business questions, clarify requirements and translate them into practical, user-focused BI solutions that support informed decision-making.

You'll use SQL and a range of analytical techniques to explore data, identify trends and explain performance in a clear and accessible way. By applying agreed data definitions, governance controls, accessibility standards and development practices, you'll ensure reporting outputs are trusted, consistent and reusable across the organisation. Working collaboratively with data engineering colleagues, you'll help resolve data quality issues and ensure reporting data is accurate, timely and fit for purpose.

A key part of the role will involve supporting the ongoing simplification and rationalisation of reporting across the organisation. You'll identify opportunities to remove duplication, streamline processes and automate repeatable activities, helping to improve efficiency and create a more consistent reporting landscape. Alongside this, you'll develop clear documentation, user guidance and knowledge-sharing materials that encourage adoption and strengthen self-service capability.

You'll manage your own workload through to completion, proactively identifying risks, dependencies and key decisions, while contributing ideas, peer reviews and continuous improvement initiatives that strengthen the wider BI community. Through collaboration, technical expertise and a focus on delivering value, you'll help ensure colleagues have access to the insight they need to make better business decisions.

Success in this role means delivering high-quality reporting and insight that colleagues trust and rely on to make informed decisions. You'll create reports and dashboards that are intuitive, reliable and aligned to agreed outcomes, quality standards and delivery timescales, enabling stakeholders to confidently use data to understand performance and identify opportunities.

You'll help establish a consistent approach to metrics and definitions, ensuring they are clearly documented, understood by users and applied across reporting solutions. By driving simplification, standardisation and automation, you'll reduce manual effort and duplicated reporting, creating more efficient and sustainable ways of working.

Just as importantly, you'll build strong relationships with stakeholders through clear communication and a collaborative approach. By providing trusted insight and helping users understand the story behind the data, you'll foster confidence in the reporting and analytics capability and support better decision-making across the organisation.
