Data Engineer IR35

Staff Data Engineer AWS PySpark Data Modernisation London Contract Inside IR35

We're supporting a global, technology-led organisation undertaking a large-scale cloud data transformation programme.

This isn't a traditional Data Engineering role. The organisation is modernising hundreds of complex data pipelines, establishing reusable engineering patterns and embedding engineering excellence across its Data function.

As a Staff-level engineer, you'll combine deep hands‑on technical expertise with organisation-wide technical influence, helping shape how modern Data Engineering is delivered across multiple engineering teams.

This is an opportunity to work on enterprise‑scale data movement, cloud‑native architectures and AI‑assisted software engineering within a highly collaborative engineering culture.

• Defining technical standards and engineering patterns for a large-scale Data Modernisation programme
• Re‑engineering complex legacy data pipelines into production‑grade Py Spark
• Building scalable, reusable data movement frameworks across multiple engineering teams
• Driving best practice around AWS Glue, Apache Spark and Apache Airflow
• Designing high‑quality testing frameworks covering performance, data quality and reliability
• Leveraging Agentic AI development tools to improve engineering productivity while maintaining code quality
• Coaching and influencing experienced engineers through technical leadership rather than line management
• Working closely with enterprise architecture and platform teams to improve how data is governed, managed and consumed

• Staff, Principal or Lead Data Engineering roles
• Python and expert‑level Py Spark
• AWS Glue
• Apache Spark
• Apache Airflow
• Cloud‑native Data Engineering architectures
• Large‑scale data pipeline modernisation
• Building reusable engineering patterns within enterprise environments
• Data testing, validation and observability
• AI‑assisted software development using modern coding assistants
• Working within regulated or highly governed organisations

More important than any individual technology is your ability to combine hands‑on engineering excellence with technical leadership, helping multiple engineering teams adopt consistent, scalable engineering practices.
