We’re looking for a highly experienced Infrastructure Resilience Lead, to provide senior technical leadership across resilience, recoverability and capacity. This is a critical role focused on ensuring our technology platforms are designed to withstand failure and recover safely with defined tolerances. You’ll take ownership of the technical reality of resilience – moving us away from reactive incident response and towards proactive, design-led resilience. Reporting to the IT Infrastructure Manager, you’ll operate as a senior individual contributor, acting as the technical counterpart to the manager.
What you’ll be doing:
- Own resilience-by-design across infrastructure platforms (on-prem, cloud and hybrid), including backup, restore, failover and recovery architecture.
- Define and maintain dependency mapping and recovery sequencing for critical services.
- Lead hands-on resilience testing, including disaster recovery exercises, restore testing and failure scenario rehearsals, ensuring outcomes are evidenced and actioned.
- Ensure RTO/RPO targets are realistic, evidence-based and technically achievable.
- Own capacity planning and forecasting, ensuring platforms scale safely under load and during failure scenarios.
- Identify and mitigate capacity-related risks early, embedding monitoring, thresholds and early-warning indicators.
- Improve the quality and usability of runbooks, recovery procedures and technical documentation, reducing reliance on key individuals.
- Act as a senior escalation point for complex resilience and recovery scenarios.
- Embed resilience into design, change and release processes, working closely with engineering, operations and governance teams.
- Provide technical input into risk, audit and operational resilience discussions.
What you’ll bring:
- Deep expertise in resilience engineering, including high availability, failover, DR architecture and recovery sequencing.
- Strong knowledge of core infrastructure platforms (compute, storage, networking, identity) across on-prem, cloud and hybrid environments.
- Hands-on experience designing and delivering disaster recovery and resilience testing.
- Proven ability in capacity planning and performance analysis, using data to inform decisions.
- Experience with automation and scripting (e.g. PowerShell, Terraform, Bicep) to embed resilience into systems.
- Knowledge of ITIL/ITSM practices across incident, problem and change management.
- Confidence engaging with senior stakeholders, risk and audit teams, translating technical concepts clearly.
- A mindset that designs for failure, with a healthy scepticism of untested assumptions.
It’s a bonus if you also have:
- Experience in UK financial services or another regulated environment.
- Understanding of operational resilience frameworks (e.g. PRA, ICARA, important business services).
- Relevant certifications (Azure, VMware, Cisco, storage platforms).
- ITIL Practitioner/Specialist or resilience-related qualifications.
We reserve the right to close this vacancy early should we receive a high volume of applications.
