• Deep-dive performance tuning: partitioning strategy, memory management, shuffle/skew optimization, job cost reduction

• Set coding standards and lead code/design reviews across the team

• Drive technical decisions on data architecture, storage formats, and pipeline orchestration

• Mentor mid-level and junior engineers; act as a technical escalation point

• Partner with product, analytics, and platform teams to translate requirements into scalable systems

• Own production reliability — on-call ownership, incident response, root-cause analysis for pipeline failures
