Senior Observability Engineer | Platform & Reliability Engineering | Central London (Hybrid)
Deep, hands-on production mastery of Grafana, Prometheus, and OpenSearch (or deep open-source Elasticsearch cluster engineering with direct transferability to OpenSearch) within Kubernetes environments.
A leading technology consultancy is partnering with a UK financial services institution on a major cloud modernisation programme migrating workloads from legacy estates into Azure.
The engineering team requires a hands-on Senior Observability Engineer—whether from an Observability, SRE, Platform, or DevOps background—to stand up, scale, and govern a unified enterprise observability platform from the ground up.
This is a Contract (Inside IR35) opportunity for an initial 6–12 months duration, targeting a Q1 start.
As the successful candidate, you will:
Core Stack Deployment: Deploy, configure, and scale production-ready Grafana, Prometheus, and OpenSearch across containerised cloud infrastructure.
Onboarding Patterns & Telemetry: Build reusable instrumentation templates and onboard initial priority applications across metrics, centralised logging, and intelligent alerting.
Pipeline & Operational Enrichment: Integrate CI/CD deployment events, security scan telemetry, and enterprise CMDB metadata into unified operational views.
Service & Business Dashboards: Design outcome-focused dashboards correlating application health, security posture, and business KPIs alongside SSO and RBAC governance.
Candidate Requirements
Required Grafana, Prometheus & OpenSearch Depth: Proven hands-on experience deploying, administering, and scaling Grafana, Prometheus, and OpenSearch in production (deep open-source Elasticsearch cluster administration is viable if you can demonstrate direct transferability; commercial SaaS wrappers like Datadog or Dynatrace alone will not suffice).
Production Kubernetes & Cloud: Strong background operating observability tooling inside production Kubernetes clusters across Azure, AWS, or GCP (Azure and AKS experience is advantageous, though the core observability toolchain is the priority).
Hands-On Engineering Delivery: Demonstrable track record as a practical builder who configures and ships production systems independently, rather than operating in a high-level architectural or managerial capacity.
Regulated or High-Scale Enterprise Background: Experience delivering within UK banking, financial services, insurance, or high-scale regulated commercial environments (such as telecoms, energy, or enterprise e-commerce) with strong governance standards.
Eligibility & Availability
Full right to work in the United Kingdom without sponsorship, with availability for a Q1 start (1-month notice preferred; up to 3-month notice considered).
Nice to Have / Ideal
Azure, Entra ID & GitLab Integration: Experience configuring SSO and RBAC via Microsoft Entra ID, working within Azure/AKS estates, or feeding GitLab CI/CD security scan and deployment telemetry into Grafana or OpenSearch.
OpenTelemetry & CMDB Correlation: Familiarity with OpenTelemetry automated instrumentation standards and ingesting CMDB metadata (such as service ownership and recovery tiers) into monitoring dashboards.
An exceptional opportunity for a hands-on observability builder to own a greenfield platform rollout for a major UK financial services transformation.
