Driving data enhancement & recruitment success with LinkedIn’s unified integrations

What this post added

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.
