As a Senior DevOps Engineer, you will play a critical role in transforming how we build, deploy, and operate software accelerating our move toward cloud-native, automated, self-service delivery capabilities.

This role sits at the core of our modernisation program, supporting engineering teams to build, deploy, and scale services across multiple regional environments while helping evolve our future tenant and deployment strategy. You will work at the intersection of platform engineering, cloud infrastructure, CI/CD, and developer experience building automation and tooling that empowers teams to deliver with speed, quality, and consistency. You will also act as a key advocate for our Development Community and help nurture our DevOps culture as we transform our platform and way of working.

What you will do

• Play a lead role in the design and implementation of best-in-class software build and release technology solutions.
• Design, build, and enhance CI/CD pipelines that enable fast, reliable deployment of microservices across multiple regions.
• Support and evolve multi-tenant and multi-region deployment models as we transition to a modern environment strategy.
• Build and maintain Kubernetes-based platforms, delivering secure, scalable, and developer-friendly environments.
• Implement Infrastructure-as-Code using Terraform and Helm to standardise and automate infrastructure provisioning.
• Strengthen observability, monitoring, and alerting to proactively identify issues and support high-quality delivery.
• Improve developer experience through automation, self-service tooling, reusable patterns, and scalable pipelines.
• Embed security and compliance into delivery workflows, ensuring strong auditability and policy adherence.
• Collaborate with engineering to troubleshoot and optimise deployment processes and runtime environments.
• Champion modern DevOps and platform engineering practices throughout the engineering organisation.

What you will need to have

• Proven experience in DevOps or platform engineering roles supporting distributed, cloud-based systems.
• Strong hands-on experience with AWS and delivering production-grade cloud services, and cloud-native architectures.
• Experience with Kubernetes, container orchestration, and service deployment patterns.
• Experience with GitOps tooling such as Argo CD.
• Expertise in Terraform and Helm, with a strong automation mindset.
• Hands-on experience building and operating CI/CD pipelines including GitLab CI and Jenkins.
• Strong Docker, containerisation, and automation fundamentals.
• Familiarity with modern observability tooling and best practices.
• A focus on creating scalable, repeatable, and secure delivery workflows.
• Passion for enabling development teams and improving tooling, velocity, and reliability.

Nice to have

• Experience working in financial services or other regulated environments.
• Exposure to multi-region and multi-tenant platform strategies.
• Experience supporting systems in an event-driven environment (Kafka familiarity).
• Background in legacy-to-modern migration initiatives.
• Experience with configuration management tooling such as Ansible, Chef or Puppet.
• Knowledge of compliance automation and security policy enforcement in pipelines.

Who you are

• A proactive engineer who loves automation, simplicity, and enabling others.
• Enjoys working with people and helping coach and encourage individuals and teams along the DevOps journey.
• A systems thinker who considers scalability, maintainability, and developer experience.
• Comfortable navigating change and modernising legacy environments step-by-step.
• Collaborative, curious, and driven by continuous improvement.
