Job Description

What you'll do

• Lead technical triage for highimpact, fullstack production issues: investigate logs, traces, API calls, and database behavior to identify root causes quickly and implement safe, targeted hotfixes and patches.

• Partner with implementation, Product, and customer success teams to unblock complex customer rollouts-designing and implementing configuration changes, REST API integrations, and data flows that align with our Product Strategy priorities around AI, cloud, and data platform adoption.

• Design, build, and maintain internal tools, admin utilities, CLI scripts, and workflow automations that reduce implementation effort and time, and help teams achieve our goals for operational excellence and measurable customer value.

• Expand platform observability by enhancing dashboards, alerts, and runbooks using tools like Datadog, Sentry, and CloudWatch, helping us detect and resolve issues before they affect customers and supporting our reliability and gross margin targets.

• Improve and harden our CI/CD and deployment pipelines to support secure, scalable, and efficient operations that align with Product Strategy's focus on operational excellence and cloud readiness.

• Collaborate with core engineering to turn recurring field issues and customer feedback into prioritized backlog items, influencing roadmap decisions around AIpowered features, new product categories, and global market readiness.

• Communicate clearly and calmly with both technical and nontechnical stakeholders-inside Guidewire and with customer teams-translating complex technical findings into actionable next steps.

• At Guidewire, we foster a culture of curiosity, innovation, and responsible use of AI-empowering our teams to continuously leverage emerging technologies and datadriven insights to enhance productivity and outcomes.

What you'll bringRequired

• Demonstrated ability to embrace AI and apply it to your current role as well as datadriven insights to drive innovation, productivity, and continuous improvement.

• 6+ years of experience building, maintaining, or supporting SaaS or enterprise web applications in production environments.

• Strong handson experience with Python (ideally FastAPI or similar frameworks) and TypeScript/React across both frontend and backend services.

• Proven diagnostic skills: comfortable tracing distributed requests, analyzing logs and metrics, profiling performance, and debugging complex production issues under time pressure.

• Experience working in AWSbased, containerized environments (e.g., ECS, EKS, Docker), with practical familiarity with observability tooling such as Datadog, Sentry, or CloudWatch.

• Demonstrated experience building REST API integrations, CLI tools, admin portals, or workflow automations to solve operational or customer onboarding challenges.

• A customerfocused engineering mindset, with experience partnering closely with implementation, support, or customer success teams and balancing shortterm fixes with longterm product health.

• Clear, concise communication skills and the ability to document runbooks, postincident findings, and technical designs for diverse audiences.

Preferred

• Experience in enterprise or B2B platforms, ideally in cloud or dataintensive domains; exposure to insurance or financial services is a plus.

• Background working on or alongside product/platform strategy, SRE, or platform engineering teams focused on reliability, scalability, or AIdriven capabilities.

• Familiarity with infrastructureascode (e.g., Terraform, CloudFormation) and secure coding practices for multitenant SaaS.

• Experience contributing to roadmap discussions or influencing product direction based on production and customer insights.

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
