DevOps Engineer
placeholder

What We’re Working On

We’re supporting a fast-growing fintech platform undergoing major modernization of its real-time data infrastructure. Built on event-driven architecture and powered by Kafka, the system handles mission-critical messaging across multiple retail brands. We’re looking for a Kafka Architecture SME to help lead the next phase of remediation and optimization — ensuring scalability, security, and performance at production scale.

What You’ll Do

  • Join the team as a Kafka Architecture SME (Senior-level)
  • Own and execute a set of high-priority Kafka remediation epics
  • Upgrade Kafka/MSK clusters and harden IAM and proxy security
  • Define and implement retention, replication, and offloading strategies
  • Enable structured observability with metrics, telemetry, and alarms
  • Replace EventBridge dependencies with direct Kafka producers to reduce latency
  • Collaborate with architects, developers, and platform engineers
  • Work remotely with a global team across multiple time zones

What We’re Looking For

  • 5+ years of experience working with Kafka in production environments
  • Deep understanding of Kafka internals, replication, partitions, ISR, and retention policies
  • Hands-on experience with AWS-native Kafka (MSK) and services like S3, Lambda, KMS
  • Experience with Kafka monitoring and telemetry (CloudWatch, Grafana, etc.)
  • Strong focus on Kafka security, including IAM, secrets management, and proxy hardening
  • Comfortable working autonomously and delivering results on tight timelines
  • Fluent in English (spoken and written)

This job is 100% Remote; however, it requires candidates to be working fully within the UK timezone. Please ensure you have a comfortable office set at your desired work location.
