• Design and maintain the entitlement enforcement layer that gates product access based on plan type and contract state across Kong's multi-tenant platform.
• Own the provisioning pipeline that maps closed sales opportunities to live org configurations, reducing manual intervention and human error.
• Collaborate with product managers, RevOps, and finance stakeholders to translate billing requirements into reliable, auditable system behavior.
• Build and improve internal tooling for billing operations, including admin interfaces used by customer support and finance teams.
• Write clean, maintainable, well-tested code with comprehensive unit, integration, and end-to-end tests across a high-stakes financial domain.
• Participate in code reviews, design discussions, and architecture planning with a focus on correctness, idempotency, and operational resilience.
• Participate in on-call rotation and own incident response for billing platform services.
• Mentor junior engineers and contribute to a culture of engineering rigor and operational accountability.

• Experience designing and building event-driven architectures using Kafka, SQS, or similar messaging platforms.
• Proven experience integrating with third-party financial or billing platforms such as Stripe, Zuora, Chargebee, or usage metering systems.
• Strong understanding of distributed systems concepts including consistency, idempotency, eventual consistency, and failure recovery in financial workflows.
• Experience building microservices that consume and produce CRM events as part of automated provisioning or fulfillment workflows.
