• Own major parts of the Managed Sync architecture — from ingestion pipelines to storage and APIs — and drive its evolution as we scale. • Design, build, and operate backend services for Managed Sync using TypeScript (NestJS), Postgres, Redis, Kafka, and Kubernetes. • Implement new syncs and integrations across file storage, document, CRM, and other SaaS APIs — including auth, pagination, rate limits, and webhooks. • Design and evolve Synced Object schemas and data models that can represent large, complex external systems in a reliable, queryable way. • Build robust batch and incremental sync flows: backfills, change tracking, retries, dead-letter handling, and idempotent processing. • Raise the bar on reliability and observability: logging, metrics, tracing, dashboards, and SLOs, and use them to guide engineering priorities. • Partner with product, design, and GTM to deeply understand customer use cases (RAG ingestion, analytics replicas, bidirectional sync) and turn them into technical designs and roadmaps. • Collaborate with the Permissions / auth teams to ensure that synced data always respects native permissions and never leaks across tenants. • Provide technical leadership: mentor other engineers, influence engineering practices, and be a go-to person for hard debugging and design decisions.
