Join to apply for the Data Engineer role at Citywire


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.

We cover - and connect - all sides of the $100 trillion global asset management industry - through our news, events and insights.


Location: London, England, United Kingdom.


Culture and Values

At Citywire, we uphold a culture rooted in honesty, integrity, and fairness, where every voice is valued and heard. Our culture promotes constructive dialogue and collaboration on a global scale.


Benefits

  • Generous holiday entitlement: Start with 25 days per annum, increasing to 28 days after three years' service, and 30 days after five years' service, in addition to bank holidays.
  • 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.
  • Critical illness cover and group life assurance from day one of employment.
  • Well-being support: Access to an independent Employee Assistance Programme, available 24/7.
  • Cycle to work scheme and annual travel card loans.
  • Techscheme: Purchase the latest tech through our employer scheme, spreading the cost over 12 months with National Insurance savings.
  • After two years of continuous service, access group income protection, private medical, and dental insurance.

Citywire is an equal opportunities employer.

How Many Machine Learning Tools Do You Need to Know to Get a Machine Learning Job?

Machine learning is one of the most exciting and rapidly growing areas of tech. But for job seekers it can also feel like a maze of tools, frameworks and platforms. One job advert wants TensorFlow and Keras. Another mentions PyTorch, scikit-learn and Spark. A third lists Mlflow, Docker, Kubernetes and more. With so many names out there, it’s easy to fall into the trap of thinking you must learn everything just to be competitive. Here’s the honest truth most machine learning hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool. They hire you because you can solve real problems with the tools you know. Tools are important — no doubt — but context, judgement and outcomes matter far more. So how many machine learning tools do you actually need to know to get a job? For most job seekers, the real number is far smaller than you think — and more logically grouped. This guide breaks down exactly what employers expect, which tools are core, which are role-specific, and how to structure your learning for real career results.
