• Cross-Functional Information Architecture:Partner closely with Backend Engineers and Analytics Engineers to map out highly performant, scalable data structures, taking ownership over physical and logical modeling boundaries
• Drive Operational Excellence:Promote operational excellence across our data infrastructure by prioritizing proactive monitoring, system reliability, and overall application health just as much as building new pipelines

• Database Architecture:Advanced understanding of relational and analytical database engines. Expert knowledge of when to leverage transactional relational setups (MySQL transaction isolation levels, query performance tuning) versus highly optimized columnar/document architectures (ClickHouse, OpenSearch, BigQuery)
• Observability & Telemetry:Experience tracking system resources, logging pipeline runtimes, and setting up centralized data alerts within monitoring platforms likeDatadog
• Pragmatic & Solution-Oriented Mindset: A practical problem solver who values executing secure, stable transition steps over premature optimization or over-engineering
• Effective Communicator:Able to convey complex architectural concepts, technical designs and performance trade-offs clearly and simply
• High Autonomy & Proactive Ownership:Motivated to work independently, take charge of data initiatives
