Unified Hiring Data Integrations Platform

posts

2026

LinkedIn has developed a unified integrations platform to standardize, reconcile, and deliver hiring data at scale. This platform supports both partner-push (BuildIn) and LinkedIn-owned pull/push (BuildOut) integration models, addressing challenges of semantic variability, entity interdependency, and operational scale. Key design principles include security, isolation, observability, unified data contracts, and idempotent, replayable, and evolvable data paths. The architecture features gateway adapters for partner-facing variability and a centralized integration core. BuildIn handles partners with less mature APIs, while BuildOut provides stronger guarantees for partners with robust APIs, leveraging Temporal for workflow orchestration and Kafka for streaming. Smart throttling is implemented for quota-aware freshness control.

This post details the engineering effort behind LinkedIn's unified integrations platform for hiring data. It introduces two integration models: BuildIn (partner-push) and BuildOut (LinkedIn-owned pull/push). The platform addresses semantic variability, entity interdependency, and operational scale challenges in integrating diverse ATS and TCRM systems. Design principles emphasize security, isolation, observability, unified data contracts, and idempotency. The architecture includes gateway adapters and a core integration engine, with BuildOut leveraging Temporal for workflow orchestration and Kafka for streaming. Smart throttling is introduced for quota-aware freshness control.
