This is an exciting opportunity to join a high‑growth consultancy environment where you will shape data modelling standards, influence enterprise‑level design, and work directly with senior stakeholders across complex financial services programmes. If you enjoy combining hands‑on modelling with broader architectural thinking, this role offers significant impact and clear progression.

The Company

They are a well‑established consulting firm with a strong footprint across financial services and energy. Their data capability exceeds 300 specialists, and their Data Architecture function is known for delivering high‑quality modelling, strategy and metadata solutions across large‑scale transformation programmes. They operate in a collaborative, low‑ego environment where expertise is valued and career progression is structured and transparent.

The Role

As a Senior or Principal Data Modeller, you will:

  • Lead and deliver hands‑on data modelling across complex programmes.
  • Design relational and dimensional models for transactional, analytical and enterprise environments.
  • Define modelling frameworks, standards, and guardrails for large transformations such as migrations.
  • Shape and document metadata, lineage, catalogues and source‑to‑target mapping.
  • Contribute to ETL design and data movement patterns across platforms.
  • Work with JSON, XML, Parquet and other semi‑structured formats used across financial systems.
  • Engage senior stakeholders and guide best practice within multidisciplinary teams.
  • Principal level: provide thought leadership, support revenue activity and lead client‑facing presentations.

Your Skills and Experience

You will be a strong fit if you can demonstrate:

  • Deep commercial experience in hands‑on data modelling (relational and dimensional).
  • Ability to design logical and physical data models and explain modelling decisions to stakeholders.
  • Experience working in consulting, financial services, or energy environments.
  • Capability in ERWin or similar modelling tools such as Sparx, RSA, Visio or related platforms.
  • Understanding of ETL flows, metadata management and how data is structured for AI, ML, BI and analytics use cases.
  • Comfort operating in client‑facing settings and contributing to delivery outcomes.
  • Principal level: additional experience in leadership, client development or shaping solution direction.

What They Offer

  • Exposure to major financial services organisations and high‑impact data programmes.
  • Supportive culture with ongoing learning and a strong data community.
