Platform Engineer (Runtime), RTGS Technology

Location:

Leeds or London

This is an opportunity to do meaningful platform engineering work inside one of the UK’s most critical technology environments.

RTGS settles on average £800bn per day and is Critical National Infrastructure — the runtime platform your team builds and operates underpins how systems are deployed and run safely across RTGS Technology.

As a Platform Engineer in the Runtime team, you will be a hands‑on technical contributor, working on container orchestration and runtime infrastructure such as Kubernetes and Open Shift, delivering and operating platform capabilities, and ensuring they perform in production. You will diagnose issues, restore service, and improve the platform based on operational experience. This role follows a “you build it, you own it” model.

Key responsibilities include:

• Deliver and operate runtime platform services and support them in production over time.
• Build, configure, and operate container orchestration platforms such as Kubernetes or Open Shift.
• Build, deploy, and maintain Docker images.
• Enable delivery teams to deploy and operate their services, ensuring a self‑service approach where possible.
• Improve how workloads run on the platform, including performance, scaling behaviour, and resource utilisation.
• Enhance platform resilience and ensure predictable behaviour and recovery under failure conditions.
• Maintain and evolve the runtime platform lifecycle – upgrades, patching, and ongoing maintenance.
• Apply an automation‑first mindset to reduce manual effort and improve operational consistency.
• Participate in the on‑call rota, diagnosing, resolving, and restoring platform services.
• Ensure production issues lead to improvements in platform design, automation, or operational practices.
• Contribute to the security posture of the runtime platform.
• Maintain clear documentation for platform services and usage patterns.
• Adhere to change management and governance processes appropriate for a regulated environment.
• Contribute to a culture of continuous improvement across the platform engineering function.

• Flexible start and end times.
• 50% in-office attendance requirement that can be spread across the month, with flexibility to reflect operational commitments such as on-call and out-of-hours work.
• Working from abroad (subject to approval).

• Hands‑on experience with container orchestration platforms (e.g., Kubernetes, Open Shift, AWS EKS, Azure AKS, GKE) in a production environment.
• Experience building, deploying, and maintaining Docker images.
• Experience with Linux-based infrastructure.
• Experience supporting production systems, including participation in on-call or incident response.
• Automation-first mindset, with experience using scripting or infrastructure automation approaches.
• Understanding of how containerised workloads behave in production, including common failure modes and recovery approaches.

• Experience with Kubernetes or Open Shift in a production context.
• Ability to take ownership of runtime or infrastructure tasks and deliver a high standard.
• Experience contributing to incident response – diagnosing issues and supporting service restoration.
• Strong understanding of how runtime environments affect service reliability and performance.
• A security-conscious approach to platform and infrastructure work.
• Experience working within controlled environments, including adherence to change management processes.
• Experience collaborating with engineering teams to provide platform services, enabling rather than blocking.
• Ability to improve reliability and operational consistency through automation and sound engineering practices.

• Experience with Open Shift in an enterprise or regulated environment.
• Experience with public cloud platforms alongside on-premise infrastructure.
• Experience in financial services, payments, or other regulated or high-availability environments.
• Familiarity with infrastructure-as-code approaches and tooling.
• Experience with observability tooling – logging, metrics, alerting, and dashboards.
• Relevant infrastructure or platform…
