• Role Objective

Lead the assessment, design, and optimisation of the observability strategy for the co-location migration programme.

Ensure logging, metrics, tracing, alerting, and operational dashboards provide comprehensive visibility across the new infrastructure and application estate, enabling the successful migration of the tightly-coupled monolithic platform with minimal operational risk.

Identify gaps in the existing observability capability and recommend enhancements to tooling, processes, and architecture where required.

Key Responsibilities

• Observability Assessment & Strategy
• Review the current observability architecture across infrastructure, networks, middleware, databases, and applications.
• Assess existing logging, metrics, distributed tracing, and monitoring capabilities to determine readiness for the co-location migration.
• Develop an observability strategy that supports both migration activities and long-term operational support.
• Recommend enhancements or platform uplifts where current tooling does not provide sufficient visibility or resilience.
• Baseline Performance Analysis
• Analyse telemetry, monitoring data, dashboards, and operational trends from completed migration waves.
• Establish performance baselines for compute, storage, networking, application response times, and transaction throughput.
• Identify recurring operational issues and use historical insights to improve migration readiness.
• Define measurable service health indicators to compare pre- and post-migration performance.
• Monolithic Application Monitoring
• Design comprehensive monitoring for the tightly-coupled monolithic application estate, with particular emphasis on latency-sensitive interdependencies.
• Create real-time dashboards that provide operational visibility across infrastructure, middleware, databases, messaging, and application components.
• Ensure end-to-end transaction tracing is available to rapidly identify bottlenecks and service degradation.
• Validate monitoring coverage prior to each migration wave.
• Logging & Trace Management
• Review and standardise centralised logging across all migrated environments.
• Ensure consistent log formats, metadata, correlation IDs, and traceability across systems.
• Validate log ingestion, retention policies, indexing, and search performance.
• Ensure operational teams can rapidly investigate incidents using correlated logs and distributed traces.
• Alerting & Operational Readiness
• Review and optimise alert thresholds to minimise both missed events and unnecessary alert noise.
• Implement intelligent alerting aligned to business services and critical customer journeys.
• Define migration-specific alerting for infrastructure failures, application degradation, latency increases, replication issues, and capacity constraints.
• Support operational readiness activities including rehearsals and production cutover monitoring.
• Compliance & Audit
• Ensure observability solutions meet financial services regulatory requirements for auditability, log retention, security, and data governance.
• Validate access controls and security monitoring for observability platforms.
• Support evidence gathering for internal governance, audit, and regulatory reviews.
• Platform Improvement
• Evaluate the suitability of existing observability platforms and recommend improvements where required.
• Assess opportunities to improve automation, anomaly detection, service health monitoring, and predictive alerting.
• Define standards and best practices for observability across future migration phases.
• Stakeholder Collaboration
• Work closely with Infrastructure Architects, Application Architects, Platform Engineering, Security, Operations, and Migration teams.
• Provide technical guidance during migration planning, testing, dress rehearsals, and production cutovers.
• Produce architecture documentation, monitoring standards, operational runbooks, and knowledge transfer materials.
• Required Skills & Experience
• Extensive experience designing enterprise observability solutions within large‑scale infrastructure or data centre migration programmes.
• Strong knowledge of metrics, logging, distributed tracing, and application performance monitoring (APM).
• Experience monitoring latency‑sensitive, business‑critical enterprise applications.
• Strong understanding of infrastructure, virtualisation, networking, storage, databases, and middleware monitoring.
• Experience implementing centralised logging and observability best practices.
• Knowledge of financial services operational resilience, audit, and regulatory requirements.
• Ability to analyse complex operational telemetry and identify performance bottlenecks.
• Excellent stakeholder management and communication skills.
