Senior Site Reliability Engineer — Platform Engineering

Location: Ireland - Dublin

Summary

At Guidewire, we build the technology that helps Property and Casualty (P&C) insurance companies take care of their customers when it matters most. Our products support the core insurance lifecycle—from selling and underwriting policies to settling claims and billing customers—alongside capabilities for data management, digital portals, and predictive analytics.

These products run on the Guidewire Cloud Platform, serving hundreds of insurance providers worldwide and processing billions of dollars of business. We are a market leader, a Top Cloud Employer on Glassdoor, and a company guided by integrity, rationality, and collegiality.

We are looking for a Senior Site Reliability Engineer who wants to build software, not just operate it.

The Platform team is transforming from an operations-focused function into a modern engineering organization. We are investing in automation, developer tooling, platform capabilities, and resilient systems that make it easier to build, deploy, operate, and scale Guidewire products. This is an opportunity to help shape that transformation while working on systems that matter at global scale.

As a Senior SRE, you will design and develop software that improves the reliability, availability, performance, and operability of Guidewire’s flagship cloud platform and InsuranceSuite products. You will write production code, build internal platforms and automation, improve observability, and partner closely with product engineers to solve complex reliability challenges.

You will work across AWS, Kubernetes, Linux, databases, identity platforms, and distributed systems. The ideal candidate combines strong software engineering instincts with deep operational experience and enjoys turning recurring operational problems into reliable, maintainable software.

If your instinct is to automate, simplify, and improve the system—and if you would rather write code than click through a GUI—we would love to hear from you.

What you’ll do

• Design, develop, test, and operate software and platform capabilities for resilient, multi-tenant SaaS systems.
• Apply software engineering and SRE practices to shared infrastructure and customer-centric application environments.
• Build automation and developer tooling that improve deployment, operations, reliability, and the engineering experience.
• Develop and maintain AWS infrastructure and services using Infrastructure as Code and GitOps practices.
• Engineer and improve containerized platforms based on Docker, Helm, Kubernetes, and Amazon EKS, including networking, CNI, and ingress.
• Contribute features, bug fixes, reliability improvements, and architectural enhancements to core infrastructure systems and, where appropriate, the product itself.
• Design and operate reliable SAML/OAuth-based authentication and single sign-on platforms.
• Build observability capabilities across logging, metrics, tracing, alerting, dashboards, and application performance monitoring.
• Help evolve the platform toward self-healing operations through automation, intelligent signals, and well-designed control loops.
• Improve incident management by helping teams identify, mitigate, and learn from reliability risks and production issues.
• Support 24x7x365 follow-the-sun operations of critical production systems through automation, documentation, and effective engineering practices.
• Create clear system documentation, runbooks, and training materials that enable the wider engineering organization.
• Collaborate with product and engineering teams to define non-functional requirements for availability, performance, observability, security, and maintainability.
• Mentor teammates and raise the standard for software quality, operational excellence, and reliability engineering.
