Job description

Salary: £24,500 - 36,500 per year

Requirements

• Programming and scripting skills in high-level languages such as Python, Go, Java, or Bash to construct production-grade tooling.
• Proficiency with Linux-based systems, distributed systems, containerization (Kubernetes/GKE), and public cloud platforms (GCP/GCE).
• Understanding of modern CI/CD patterns and IaC tools such as Terraform, Ansible, or Kubernetes Config Connector (KCC).
• Knowledge of core systems and networking concepts (TCP/IP, UDP, HTTP, DNS, load balancing, and messaging protocols).
• A forward-thinking approach to automation, leveraging Generative AI and Agents (e.g., Gemini) to optimize platform operations.
• A data-driven mindset to troubleshoot complex, non-linear system behaviors in a fast-paced, high-pressure trading ecosystem.
• Strategic communication skills to translate technical requirements for cross-functional teams, coupled with an eagerness to learn independently and collaboratively.
• Hands‑on experience with telemetry tools such as OpenTelemetry, Splunk, Prometheus, and Grafana is preferred.
• Comfort working within Agile frameworks and collaborative software development lifecycles is preferred.
• GCP Professional Cloud Architect, Certified Kubernetes Administrator (CKA), or Certified Kubernetes Application Developer (CKAD) certifications are preferred.
• Experience in Financial Markets or other highly regulated, ultra‑low latency, high‑concurrency environments is highly beneficial though not essential.

Responsibilities

• Architect, operate, and support the migration of application platforms—including Messaging (Kafka, RedPanda, MQ, Pub/Sub), Service Discovery (Consul, Vault), and Data Distribution (SFTP/JScape)—to Google Cloud Platform.
• Manage cluster lifecycles, data replication, RBAC, and workload placement.
• Design, scale, and maintain our observability backbone using tools like OpenTelemetry, Splunk, Prometheus, and Grafana.
• Establish and continuously improve metrics, logs, alerting strategies, SLIs, and SLOs to enable fast issue detection.
• Engage with urgency in live production incidents, take ownership of minor incidents, lead post‑mortems, and ensure rapid system recovery.
• Actively identify operational toil and eliminate manual effort through code, automation, and systematic platform improvements.
• Contribute to disaster recovery (DR) strategies, continuous systems resiliency testing, and present reliability improvement suggestions to the Product backlog.
• Lead technical discussions for assigned scope, present solution options, collaborate across functional teams, and mentor junior SRE colleagues.
