Senior DevOps Engineer
At Fiserv, we are modernising our global payment processing platform to enable scalability, resilience, and rapid delivery across regions. 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.

- 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
