Senior Data Engineer

We're seeking a Senior Data Engineer to transform our analytics infrastructure from monolithic SQL/PostgreSQL systems into a modern Azure-based data platform. This permanent position focuses on building architecture for long-term evolution, not just migration.

You'll bring 5+ years of data engineering experience with proven expertise implementing enterprise-scale data platforms. You'll architect solutions using modern patterns, establish data pipelines and CI/CD practices, and mentor our team while building systems that evolve with emerging technologies.

We need someone who builds maintainable, scalable, adaptable systems. We're committed to Azure but not wedded to specific products – we value pragmatic solutions based on actual needs.

Structure & Expectations

• Reports to: Product organisation – you'll work closely with product teams to align data capabilities with business objectives

• Location: London office 3 days per week, remote work rest of the time

• Team: You'll be the senior technical lead and engineer for data platform initiatives, working with business analysts, engineers, and product stakeholders

• Timeline: Initial focus on migration (6 months), then platform evolution and capability expansion

• Strong presentation skills for technical and non-technical audiences

• Architecture diagrams, data flows, runbooks

What You'll Do

• Architect a modern data platform for long-term business evolution

• Establish engineering best practices for data, governance, and operations

• Build robust batch and real-time processing pipelines (mostly combining a web application’s database with various user analytics data sources and other APIs)

• Create comprehensive documentation and training materials

• Translate business requirements into maintainable technical solutions

Why This Matters

You'll establish the foundation for our data platform's next decade. This new platform will be the engine for our next generation of internal and customer products and will empower our business with real-time insights to make faster, smarter decisions.
