• Collaborate with product owners, architects, data scientists, and business stakeholders to translate complex business requirements into robust technical solutions.
• Mentor and coach junior and mid-level engineers, fostering a culture of engineering excellence, continuous learning, and innovation.
• Drive adoption of DevOps best practices including CI/CD pipelines, infrastructure as code (Terraform), automated testing, and observability.
• Evaluate and recommend new technologies, frameworks, and patterns to improve developer productivity, system reliability, and customer outcomes.
• Contribute to the evolution of our claims platform architecture, ensuring solutions are secure, performant, and maintainable at enterprise scale.
• Partner with cross-functional teams across Claims IT to ensure consistency in standards, patterns, and tooling.

• Excellent communication and collaboration skills with the ability to influence technical direction across teams.

Preferred Qualifications:

• Experience with Guidewire ClaimCenter or other Guidewire products is a significant plus.
• Experience with FastAPI, Flask, or Spring Boot for building backend services.
• Familiarity with containerization (Docker) and orchestration (ECS/EKS).
