Key Responsibilities • Inventory inbound/outbound interfaces, data owners, triggers, failure modes and service-level expectations. • Define and implement secure REST/webhook/event interfaces and stable schemas for competition management, rankings, education, payment and reporting. • Design canonical identifiers and matching behavior to avoid duplicate or mismatched person records. • Implement API gateway policies, authentication, authorization, throttling, retries, idempotency and observability. • Create mocks, sandboxes, contract tests and integration test datasets to unblock parallel delivery. • Coordinate integration acceptance with client teams responsible for external systems. • Document error codes, reconciliation processes, retry/compensation logic and support procedures. • Support end-to-end tests, migration rehearsals, cutover, peak event loads and incident triage. Advanced Technical Responsibilities • Build and govern API contracts using OpenAPI/Swagger, JSON Schema and versioned integration specifications, including authentication, scopes and service-account access. • Implement resilient REST/webhook/batch integrations with retries, backoff, idempotency, replay protection, rate limits, correlation IDs and dead-letter processing. • Engineer interfaces for federation/member associations, external competition management, rankings, education/LMS boundaries and payment provider reconciliation without assuming ownership of out-of-scope engines. • Design canonical identifiers and cross-system entity mapping for person, organization, license, event and results records; implement traceable data transformations. • Own integration test harnesses, consumer/provider contract tests, synthetic test data, interface monitoring, failure dashboards and cutover validation.
