Senior Software Engineer (Platform Engineering)

This role is part of Product Development & Operations (PDO), the organization responsible for building and operating the Guidewire Cloud Platform and products that our customers run in production every day. PDO s FY26 priorities center on secure, scalable, and efficient platform operations, accelerating AI, cloud, and data platform adoption, and ensuring every customer is successful, referenceable, and realizing measurable value.

As a Senior Software Engineer in Platform Engineering, you will help build and evolve the Kubernetes-native, multi-tenant cloud platform (GWCP/Atmos) that underpins hundreds of services and AI-powered capabilities across Guidewire. Your work will directly support PDO s goals to improve service reliability, enhance security and compliance, and enable new GenAI-powered features that span our product portfolio. What You ll Do

• Own things end-to-end. Pick up a problem, design the solution, ship it to production, and keep it running. No throwing code over a wall.
• Build core platform components the kind of infrastructure that hundreds of services depend on. Your code matters at a foundational level.
• Design for elegance under complexity. Workflows, automation, developer tooling youll tackle problems where the naive solution doesnt survive contact with production.
• Collaborate across teams on technical designs. We value well-argued RFCs and design docs over top-down mandates.
• Contribute upstream. When open-source tools dont do what we need, we fix them and send PRs not fork and forget.

What Were Looking For

• 8+ years building and operating systems in SaaS/PaaS environments at enterprise scale
• Deep Kubernetes expertise not just kubectl apply, but understanding schedulers, controllers, CRDs, networking, and the broader ecosystem
• Strong cloud fundamentals (AWS preferred, Azure/GCP also welcome) you know the difference between what the cloud gives you and what you have to build yourself
• Proficiency in Go, Java, or Python with hands-on backend service development (Go is our primary language bonus if its yours too)
• Solid distributed systems intuition you think about failure modes, consistency trade-offs, and what happens at 3 AM when traffic spikes
• Container-native mindset Docker and friends are second nature, not something you Google each time
