We’re partnering with a highly established, regulated organisation to appoint an experienced Principal Business Analyst into a growing Business Change function.

This is a high-impact opportunity for a commercially minded BA who enjoys working on complex, organisation-wide change
, influencing senior stakeholders and taking ownership from initial problem definition through to implementation.

You’ll join a collaborative Business Analysis team and play a key role in shaping how the organisation approaches major transformation initiatives, while also providing guidance and mentoring to other BAs.

The Opportunity:

As Principal Business Analyst, you’ll take ownership of complex, long‑term projects spanning technology, operations, data and business change.

You’ll work closely with Project and Product Managers, technology teams and senior business stakeholders to understand challenges, define requirements and translate business needs into practical solutions.

The role is particularly suited to someone who enjoys being hands‑on and involved throughout the full project lifecycle
, rather than operating within a narrowly defined BA discipline.

You’ll also have regular exposure to senior leadership, so the ability to communicate clearly, challenge constructively and present complex information with confidence will be essential.

What you’ll be doing:
  • Lead business analysis across complex, high‑risk and large‑scale change initiatives.
  • Analyse business problems, opportunities, processes and systems to identify improvements.
  • Lead workshops and facilitate requirements gathering with diverse stakeholders.
  • Define and document high‑level and detailed business requirements.
  • Undertake impact assessments and identify operational, technical and process gaps.
  • Develop business cases, change proposals and supporting documentation.
  • Contribute to business architecture, strategic alignment and continuous improvement.
  • Work closely with technology teams throughout solution design, development and implementation.
  • Support system, user and operational acceptance testing.
  • Help ensure business change is successfully implemented and adopted.
  • Influence stakeholders across multiple functions and levels, including senior leadership.
  • Provide guidance, mentoring and quality oversight to other Business Analysts.
  • On smaller initiatives, operate across both BA and project delivery responsibilities.
What we’re looking for:
  • 5+ years' Business Analysis experience
    .
  • Background within Financial Services
  • Strong experience across technology, operations and business change.
  • Experience working across Agile, Waterfall and hybrid delivery environments
    .
  • Strong understanding of IT operations, systems and development practices.
  • Experience with business architecture and strategic alignment.
  • Excellent stakeholder management and communication skills.
  • Confidence presenting to and influencing senior/C‑suite stakeholders.
  • Experience managing third‑party relationships.
  • The ability to lead, influence and bring structure to complex change.
  • A highly analytical and commercially aware approach.

A Business Analysis or Business Architecture qualification would be advantageous.

The person:

This is a role for someone who is hands‑on, resilient and comfortable operating in ambiguity
.

You’ll need to be someone who can move between strategic conversations and detailed analysis, create structure where it doesn’t already exist and remain effective when priorities change.

The successful individual will be:
  • Naturally curious and analytical.
  • Energetic, proactive and self‑motivated.
  • Comfortable challenging and influencing at senior level.
  • Resilient when projects or priorities change.
  • Confident working…
