The team is using Go. • Experience with distributed systems, event-driven architectures, data pipelines, APIs, data modeling, or data-intensive services. • Familiarity with analytical, operational, or warehouse data stores such as ClickHouse, Postgres, Snowflake, Redshift, BigQuery, Databricks, or equivalent technologies. • Experience diagnosing production issues and improving system reliability through metrics, logs, traces, alerting, and other observability practices. • Experience working in a cloud environment and with infrastructure-as-code or equivalent deployment and operations tooling. • Ability to take an ambiguous problem from discovery and scoping through design, implementation, launch, and ongoing operation. • Clear, thoughtful communication and a collaborative approach to working with technical and non-technical partners. • Experience with experimentation, A/B testing, analytics, data platforms, or similarly data-intensive products.
