Job summary

Global technology & software product company in London is seeking a Senior Java Engineer to join the Platform Team. You will design and build distributed services in core Java, work with Kafka event streaming, and orchestrate deployments on Kubernetes within a hybrid working setup.

The role offers a salary of £120,000 to £125,000 basic with an extensive benefits package and 2 days in the office per week.

Qualifications

At least 7 years’ experience as a backend Java developer, building complex distributed systems.
A deep understanding of core Java, data structures and concurrency, not just framework knowledge.
Hands-on experience with Kafka and event-streaming frameworks such as Flink, Kafka Streams or Spark.
Practical Kubernetes experience, including troubleshooting production issues.
Experience tuning JVM performance - garbage collection, CPU hotspots and heap dump analysis.

Responsibilities

Design and build distributed services from the ground up, working with core Java rather than solely relying on heavy framework usage.
Develop event-driven systems using Kafka and event-streaming frameworks at scale.
Orchestrate deployments on Kubernetes, defining services, deployments and stateful sets.
Tackle hard problems around data consistency and availability, and shape how the platform evolves.
Mentor other engineers while continuing to learn from senior peers across a global team.
