Estuary unifies CDC, batch, and streaming into one platform. As Estuary’s first CSM, own post‑sale relationships with data engineers and platform leads. Hybrid role: relationship owner and technical problem‑solver, building CS function from scratch. What You'll Do: build onboarding/health/AM playbooks; own journey from onboarding to renewal/expansion; run EBRs; use AI tools to build health dashboards; track stakeholders; monitor account health and preempt risk; troubleshoot most issues; loop in Solutions Engineering as needed; identify expansion; act as customer advocate to Product/Engineering. What You'll Bring: CS or technical account management experience (SaaS/data infra/dev tools); builder’s instinct; comfort with APIs, databases, warehouses, ETL/ELT; ability to use AI to build reporting/dashboards; strong AM instinct and communication; proactive ownership. Nice: Snowflake/Databricks/BigQuery/Kafka/Fivetran/Airbyte; early‑stage; CDC/streaming familiarity. Why Estuary: build CS from the ground up (report to CEO), high‑performing team, remote‑first, quarterly offsites, competitive salary/equity/benefits.
