Solutions Engineer

• As a (Software) Engineer - Data Integrations / Platform you are part of an engineering team and ensure that new source systems are reliably connected to a data platform
• You develop and operate data connectors to additional source systems and implement ingestion pipelines (e.g., with Dagster or comparable tools)
• You integrate source systems via APIs (REST, GraphQL, SDK) and implement the appropriate authorization logic per system (e.g., Active Directory)
• You ensure integrations are production-ready: clean error handling, retries with exponential backoff, clear distinction between transient and permanent errors, and robust protective mechanisms such as circuit breakers
• You establish observability: structured logs with context (e.g., correlation IDs), monitoring and alerting (e.g., Prometheus/Grafana), and health checks
• You implement incremental synchronization: delta detection (timestamps, checksums, versions), sync state, and sensible strategies for deletes (soft/hard delete)
• You ensure quality through automated tests (unit/integration/E2E) and deliver, per connector, complete, reproducible pipelines and Dagster assets (Extract, Transform, Load)
