About the Role: We are seeking an SDE-3 Backend Builder to own the CRM Bulk Import product end-to-end. Bulk Import is the data on-ramp into HighLevel — the system that pulls contacts, opportunities, custom objects, and pipelines out of external CRMs (HubSpot today, more tomorrow) and lands them cleanly inside our customers’ workspaces, often at scale of millions of records per import. The architecture spans an orchestration layer (bulk-actions) that drives Pub/Sub-based fan-out, a stateless read-side proxy (external-import) that talks to third-party CRM APIs and maps payloads into HighLevel shape, OAuth token resolution, ID-mapping in Redis, and downstream writes into contacts, opportunities, and custom-fields services. You will own this pipeline horizontally — designing the workers, the proxy, the contracts, and the operational story — while keeping the system CRM-agnostic so adding the next integration is a small change, not a rewrite. This role emphasises deep backend ownership: distributed workflows, idempotency, throughput, and resilience against flaky upstreams. You will operate with high autonomy, with enough frontend fluency to ship the occasional UI surface (import setup, progress, error reporting) without waiting on anyone.
