• Deep familiarity with AWS cloud services (S3, Lambda, IAM, EC2, Glue etc.)

• Experience with PostgreSQL, MongoDB, Clickhouse or other columnar/NoSQL systems

• Strong understanding of data modeling, partitioning, schema evolution, and performance tuning

• Understanding of data quality, lineage, orchestration, and governance

• Ability to design systems in hybrid environments (on-prem + cloud)

• Excellent communication, documentation, and teamwork skills

• Experience with NATS JetStream, Kafka, or high-throughput messaging systems

• Familiarity with GPU-based CV pipelines, ML datasets, or annotation workflows

• Experience with ClickHouse Materialized Views, Replicated Tables, or S3-backed storage

• Experience working in a regulated, safety-critical, or high-uptime environment
