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.
