What You ll Do

Define and evolve the canonical data model (Person, Employment, benefit domains), the Global ID scheme, and the custom-attribute extensibility model

Design the canonical Core API resource catalogue contract-first OpenAPI v3, shaped by the canonical model rather than a 1:1 port of 300+ legacy APIs plus BFF screen-composition conventions

Build the serving layer: BFF, API gateway, and process services as the sole consumer boundary, with CQRS read APIs and a bounded consistency window

Build the mediated write path (UI ODL system of record): sync-confirm by default, async-accept writeback via saga, transactional outbox, and compensation, with read-your-writes and pending-write handling

Build the eligibility/personalization rules layer: precompute parameters and evaluate expressions against stored data, reusing an existing evaluation library

Build the practitioner console: crosswalk editor, reference-data management, survivorship and match-threshold editors, and a daily-use steward queue with roles, permissions, and audit

Implement service-to-service zero-trust security: workload identity,



per-call authorization, gateway edge auth, and row-/column-level security

What We re Looking For

5+ years of Java / Spring Boot building production microservices

REST API design with contract-first OpenAPI v3; API gateway experience (Spring Cloud Gateway or similar)

Distributed-systems patterns in production: CQRS, saga, transactional outbox, idempotency, compensation/rollback

Data-modeling fundamentals: logical/physical modeling, identifier design, PostgreSQL (including JSONB trade-offs) Kafka-based integration

Security: OAuth2/OIDC, workload identity, zero-trust patterns, row-/column-level security

React or Angular with data-dense UI patterns editable grids, workflow/approval queues, audit trails
