- Experience designing analytics and reporting architectures (data contracts, schemas, SLIs/SLOs, backfill strategies, latency vs. cost trade‑offs).
- Hands‑on experience with cloud and big‑data technologies (e.g., GCP, BigQuery, Dataflow, Kafka, Beam/Spark) and integrating them into user‑facing products.
- Experience driving engineering-wide improvements in reliability, observability, testing, or developer productivity in a production environment.
