• Build configurable maker-checker approval frameworks that enforce multi-level approvals, segregation of duties, and delegation policies.

• Implement entitlement and governance controls, including role- and attribute-based access, fine-grained UI permissions, and full audit trails.

• Design event-driven integrations with Kafka to support asynchronous processing, real-time notifications, and ServiceNow connectivity.

• Build high-volume React and TypeScript interfaces, including dashboards and task inboxes, that give users clear visibility into their work.

• Event-Driven Architecture: Strong Kafka experience for asynchronous processing, event-based workflows, notifications and ServiceNow integration.

• Proficiency in React and TypeScript for building complex, high-volume enterprise user interfaces.

• Strong communication and stakeholder management skills, with a bachelor's degree or equivalent experience.
