What they actually want (must-haves)
  • Strong experience building and operating production software systems, preferably in platform, infrastructure, backend, or data-intensive environments.
  • Deep understanding of distributed systems trade-offs: reliability, idempotency, replay, eventual consistency, ownership boundaries, compatibility, and operational failure modes.
  • Practical experience with PostgreSQL or other relational databases, including schema design, migrations, transactions, replication, or operational performance.
  • Experience with Kafka, event streaming, CDC, Debezium, or adjacent data-movement technologies.
  • Experience building software that other engineers use: CLIs, internal platforms, control planes, automation, CI validation, developer tooling, or self-service workflows.
  • Familiarity with Kubernetes and cloud or infrastructure platforms, including runtime isolation, deployment, observability, and operational ownership.
Nice to have
  • DataHub or other data catalog, lineage, or governance systems.
  • Open table formats such as Apache Iceberg, object-store-backed data lakes, S3, BigQuery, ClickHouse, or analytical storage systems.
  • GitHub Actions, policy-as-code, infrastructure-as-code, controllers, operators, or reconciliation-based systems.
  • Data contracts, schema registries, Protobuf, Avro, JSON Schema, compatibility checking, field-level metadata, or contract testing.
  • Experience supporting analytics, AI/ML, feature-store-style access patterns, or cross-domain product-service integrations.
