Role Overview

We are seeking a Site Reliability / Resilience Engineer to support a large-scale, enterprise technology environment. This role focuses on improving the reliability, availability, and resilience of critical services across complex, distributed systems.

You will work across cloud, infrastructure, and application ecosystems, helping ensure services are observable, recoverable, and aligned with both engineering best practices and regulatory resilience requirements.

Key Responsibilities

• Support reliability and resilience across cloud platforms (AWS, Azure, GCP)
• Work across infrastructure, networks, data centres, and application platforms
• Analyse and map service dependencies and critical service chains
• Contribute to the design and implementation of resilience and recovery strategies (RTO/RPO, failover patterns)
• Support vulnerability identification and risk reduction activities
• Enhance observability, monitoring, and resilience tooling across services
• Ensure alignment with UK Operational Resilience Policy Framework (PRA/FCA/Bank of England)
• Support ITIL-aligned processes, including incident, change, and release management
• Drive improvements in service stability, reliability, and performance

Skills & Experience

• Strong experience across enterprise technology environments:
• Cloud platforms (AWS, Azure, GCP)
• Infrastructure, networking, and data centres
• Application platforms and integration layers
• Strong understanding of:
• Service chain and dependency mapping
• Vulnerability and risk management
• Recovery models (RTO/RPO) and resilience patterns
• ITIL-based service management practices
• Experience with enterprise tooling such as ServiceNow
• Exposure to observability or monitoring platforms (beneficial but not essential)
• Familiarity with UK Operational Resilience frameworks (PRA/FCA/Bank of England)

This is a strong opportunity for someone who combines Site Reliability Engineering principles with a focus on operational resilience, observability, and large-scale enterprise systems.
