Start Date: ASAP

Duration: 31/03/2026

Rate: £430p/d via Umbrella

Key Responsibilities:

* Expert-level knowledge of the Elastic Stack (Elasticsearch, Logstash, Kibana, Beats), with proven experience in architecting, deploying, and managing ELK infrastructure across distributed, high-performance environments.
* Strong understanding of index lifecycle management (ILM), shard optimization, and cluster health monitoring to support low latency applications.
* Practical and working knowledge of IP networking and data flow within distributed systems.
* Experience integrating ELK with packet capture/analysis tools to enhance observability of real-time systems.
* Hands-on expertise in data pipeline creation, ingestion strategies, and performance tuning of Logstash and Beats for scalable telemetry.

* Experience designing and working with APIs (REST/JSON/XML) and integrating third-party data sources into the ELK stack.
* Exposure to Solace, 29West, Tibco, or other low latency messaging platforms is advantageous for understanding event-driven architectures in financial systems.

* Working knowledge of security best practices, including RBAC, TLS, and audit logging in Elasticsearch.
* Experience with observability platforms such as ITRS Geneos and their integration with ELK is a strong plus.
* Comfortable with multi-site replication, cross-cluster search, and disaster recovery configurations for global deployment.
* Strong understanding of Linux systems, containers, and cloud-native observability stacks.
* Organized, self-driven, and able to manage priorities in a dynamic, high-performance trading environment.
