Summary
👤
Senior🎓
Top SchoolJohn Penner is an Engineering Manager in New York with 11 years of hands-on software engineering experience and a decade-plus track record of architecting scalable data and billing systems. He blends individual-contributor depth—building ETL pipelines, migrating warehouses to Snowflake, and optimizing data throughput—with people-first leadership, growing teams and shifting infrastructure ownership into engineering via Terraform and ABAC/RBAC guardrails. At Sony he rebuilt a legacy accounting system to process billions of transactions and cut monthly royalty processing from days to under an hour; at earlier roles he scaled ad and video data pipelines to tens of billions of events. Comfortable still contributing code (C#, Python, AWS), he prefers guiding teams to deliver reliable products using CI/CD, feature flags, telemetry, and DevX tooling. Colgate-educated and known for pragmatic migrations and cross-functional collaboration, he also quietly organizes outreach like AllStarCode visits to broaden the engineering pipeline.
