Job Description

Working for a renowned financial services organisation

Your new role

We are seeking a Data Engineer to support the replacement of a legacy ETL tool with a modern Apache Spark based data platform. This is a hands‑on engineering role focused on building and supporting Spark jobs, with an emphasis on performance, reliability, and scalability.

The role is focused on building nonperformance Apache Spark jobs, with a strong emphasis on performance optimisation. It is primarily Java‑based, with Python strongly encouraged; experience across Java, Python, and Scala is ideal, with Java and Python being the preferred combination.

The role sits within a small Agile delivery team of four engineers (two onshore and two in Shenzhen), working closely with a Senior Data Engineer. You will be responsible for development work, sprint delivery, demos, documentation, and stakeholder engagement. This position suits a mid‑level engineer with strong Spark development experience rather than design, infrastructure, or management responsibilities.

What you'll need to succeed

  • Strong hands‑on experience with Apache Spark - Writing and tuning Spark jobs /PySpark development experience.
  • Strong experience working in with containerised environments using Kubernetes.
  • Experience with programming in Python or Scala
  • Exposure to Big Data technologies and distributed data processing
  • Have some working knowledge of Java or Java Spring boot development background
  • Experienced in an Ops way of working, not pure development only – you know how to deploy solutions.
  • Experience with OpenShift would be highly desirable!
  • Experience working in an Agile way of working (Scrum, sprints, demos)
  • Financial services or professional services experience required.

What you'll get in return

Flexible working options available.
