Overview

Data Engineer

We’re looking for a Data Engineer with strong Python skills and experience in event-driven systems to join our growing data team. This isn’t your typical “pipelines-for-analysts” role - you’ll be building real-time systems that power applications, tooling, and commercial products across the business.

What you’ll be doing
  • Build and maintain event-driven data pipelines that power Citywire’s Catalyst platform.
  • Design resilient, fault-tolerant workflows using AWS services such as Lambda, Kinesis, SQS, DynamoDB Streams, and EventBridge.
  • Implement processors that ensure data consistency across DynamoDB, PostgreSQL (Aurora), OpenSearch, and BigQuery.
  • Modernise legacy batch processes into stream-first architectures.
  • Build and integrate APIs to enable smooth publishing and consumption of events across systems.
  • Collaborate with engineers on greenfield and existing projects, balancing speed with resilience.
  • Take ownership of key pipelines and services, ensuring reliability, performance, and scalability.
  • Share best practices and mentor others in event-driven data engineering.
What we’re looking for
  • Technical Skills: Proven experience in data engineering or backend development, with solid Python skills and hands-on use of AWS event-driven services.
  • Event-Driven Knowledge: Understanding of DLQs, retries, buffering, idempotency, and resilient design patterns.
  • Cloud & CI/CD Experience: Familiarity with Terraform, Git-based workflows, and cloud-native deployments.
  • Database Skills: Experience with SQL and NoSQL databases such as PostgreSQL, DynamoDB, or OpenSearch.
  • Problem-Solver: Comfortable working in Linux environments and confident debugging logs, scripts, and production issues.
  • Additional Skills: Exposure to Kafka, Spark, or dbt Core, with an interest in domain-driven data contracts.

Our perks

  • Flexible working options.
  • £480 annual allowance for well-being activities or gym memberships, with assistance available for monthly or annual costs.
  • Eye-test and glasses allowance.
  • Competitive private pension scheme.
  • Critical illness cover and group life assurance from day one of employment.

Where to Advertise Data Engineering Jobs in the UK (2026 Guide)

Where to advertise data engineering jobs UK in 2026: the specialist boards and channels that reach Spark, dbt, Snowflake and platform engineering talent. Data engineers occupy a distinct discipline that sits between software engineering, data science and cloud infrastructure — and the strongest candidates identify firmly with the data engineering community rather than with adjacent roles. General job boards consistently conflate data engineering with data analysis, data science and BI development, producing high application volumes but low candidate quality for specialist pipeline and platform roles. This guide, published by DataEngineeringJobs.co.uk, covers where to advertise data engineering roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Data Engineering Jobs UK 2026: What to Expect Over the Next 3 Years

Data Engineering Jobs UK 2026: roles, salaries and the trends shaping UK data engineering hiring over the next three years — Spark, dbt, lakehouse and AI. Data engineering has become one of the most strategically important disciplines in the entire technology sector — and one of the most reliably in-demand. Every organisation that wants to use data to make decisions, train AI models, personalise products, manage risk, or understand its customers depends on data engineers to build the infrastructure that makes any of that possible. Without well-designed, reliable data pipelines, the most sophisticated machine learning model is worthless and the most ambitious analytics strategy is undeliverable. That foundational importance has made data engineering hiring remarkably resilient through the technology market corrections of the past few years. Where headcount reductions fell heavily on some engineering disciplines, demand for data engineers held firm — because the work of building and maintaining data infrastructure cannot be deferred in the way that some product development can. The data keeps coming. The pipelines need to work. But the data engineering jobs market of 2026 is not simply a stable version of what it was three years ago. The discipline has undergone a series of architectural shifts — from batch to streaming, from on-premise data warehouses to cloud-native lakehouses, from hand-rolled pipelines to declarative transformation frameworks, and most recently toward AI-augmented data engineering workflows that are beginning to reshape what the role looks like in practice. The employers hiring data engineers today are asking for a meaningfully different skill set than those hiring three years ago. The candidates who will thrive over the next three years are those who understand where the discipline is heading — which architectural patterns are becoming standard, which technologies are defining the modern data stack, and how the definition of a data engineering career is evolving toward a richer intersection of infrastructure, analytics, and AI enablement. This article breaks down what the UK data engineering jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.
