Who Are We Looking to Add to Our Team?

We’re looking for an experienced Principal Data Architect to turn complex client requirements into scalable data solutions for global brands. You’ll lead technical discovery, design end-to-end data architectures, and build roadmaps that connect customer data, identity, and marketing technology to measurable business outcomes.

Working closely with client stakeholders and our Data Engineering teams, you’ll provide technical direction, guide architecture decisions, and ensure solutions are robust, scalable, and aligned with business goals.

Develop technical roadmaps, estimate delivery effort, define project phases, and secure client sign-off before implementation.

Evaluate data technologies and tools based on business requirements, scalability, performance, and cost.

Guide Data Engineering teams in designing and optimising batch, event-driven, and low-latency data pipelines.

Establish best practices for data validation, monitoring, performance optimisation, and governance.

Translate complex technical concepts into clear recommendations that demonstrate business value.

Mentor engineers and consultants, lead technical reviews, and drive continuous improvement.

Support client pitches, technical presentations, workshops, and opportunities to expand existing engagements.
