- 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.
- Solid understanding of multi-tenant SaaS architecture and the complexity of enforcing per-org entitlements at scale.
- Experience with Kubernetes and container orchestration for deploying and operating production services.
- Strong computer science fundamentals including data structures, algorithms, and system design.
- Experience with CI/CD pipelines and tools such as GitHub Actions or Jenkins.
