Summary

Guidewire’s Product Development and Operations (PDO) organization builds and runs the cloud platform that powers the world’s most trusted P&C insurance software. You’ll join a collaborative, agile group building high‑performance modeling and configuration services that accelerate how insurers design and deploy products. Our culture values curiosity, humility, and practical innovation in a modern cloud-native stack.

As a Senior Full‑Stack Software Engineer, you will design and build elegant, high‑impact capabilities for insurance content transformation and modeling, advancing Guidewire’s shift toward AI‑driven development and highly scalable SaaS solutions. You’ll combine deep engineering craft with AI‑native coding approaches to extend complex systems quickly and safely, helping deliver secure, reliable cloud services at scale.

Your work will directly support PDO’s mission to embed GenAI across our products and improve operational excellence, contributing to Guidewire’s broader goal of transforming how the world’s P&C insurers do business through our cloud platform that unifies digital, core, analytics, and AI.

Job Description

What you’ll do

Design, build, and maintain full‑stack capabilities for APD (Advanced Product Designer) as well as insurance content transformation that make it faster and safer for insurers to model, configure, and launch products on Guidewire systems, aligned with PDO’s AI‑ and cloud‑first priorities.
Implement robust, scalable microservices and APIs in Java on AWS, using Kubernetes and Docker to deliver secure, reliable, and cost‑efficient cloud services.
Develop intuitive, performant front‑end experiences using JavaScript/TypeScript frameworks that enable business and technical users to configure complex insurance products with confidence.
Leverage AI‑assisted development tools (such as Claude Code or Copilot) to rapidly generate, refactor, and extend code while maintaining high engineering standards, tests, and observability.
Apply enterprise architecture and software design patterns to evolve our systems for reliability, maintainability, and performance, contributing to PDO’s goals for operational excellence and service quality.
Collaborate closely with product management, architects, and fellow engineers in an agile environment to break down complex domain problems, run technical spikes, and ship incremental value.
Contribute to and improve our CI/CD, DevOps, and testing practices (for example, TeamCity, Kubernetes-based deployment pipelines) to support faster, safer releases and higher automation.
At Guidewire, we foster a culture of curiosity, innovation, and responsible use of AI—empowering our teams to continuously leverage emerging technologies and data-driven insights to enhance productivity and outcomes.

Required

What you’ll bring

Demonstrated ability to embrace AI and apply it to your current role as well as data-driven insights to drive innovation, productivity, and continuous improvement.
5+ years of professional software development experience, ideally in SaaS or cloud-based products.
Strong proficiency in core Java, with experience building and maintaining production microservices on a major cloud platform (preferably AWS).
Hands-on experience with JavaScript or TypeScript on the front end; experience with Python is a plus for tooling, automation, or data-related tasks.
Solid understanding of common enterprise architectural and software design patterns, and proven experience applying them in real-world SaaS applications.
Practical experience with containerization and orchestration (Docker, Kubernetes) and familiarity with CI/CD and DevOps practices and tools (for example, TeamCity, Git-based workflows).
Proven ability to use AI-assisted coding tools (e.g., Claude Code, GitHub Copilot) to accelerate development while exercising strong judgment around code quality, testing, and security.
Excellent communication skills, with the confidence to share and defend ideas based on technical merit, and the humility and curiosity to learn from peers.

Preferred

Experience in the property & casualty insurance domain, financial services, or other complex, highly regulated business domains.
Experience with business rules engines or decision modeling, particularly DMN FEEL.
Background in AI/ML development patterns, including prompt engineering, model tuning, or integrating AI services into production systems.
Prior work on configuration or modeling platforms, low-code/no-code tools, or developer/productivity platforms.
BS/MS in Computer Science, Software Engineering, or a related technical field, or equivalent practical experience.

Your Impact

We believe in clarity and setting you up for success. In your first months, you’ll immerse yourself in architecture and domain, pair with senior engineers to implement features end-to-end, and start contributing improvements to our microservices, UI, and pipelines. As you ramp, you’ll own impactful projects—such as new prod
