Rockstar🎓
Top SchoolStephen Kiers is a Principal/Staff software engineer with 10+ years of experience building and operating long-lived platform and data systems for product-led organizations, currently driving platform stability and data modernization at The Muse. He’s hands-on across application code, data engineering, and infrastructure, having owned Shopify’s experimentation platform—where he redesigned core workflows as explicit state machines to triple adoption and reduce on-call load—and led cross-cloud Snowflake/dbt/Redshift consolidations at scale. Stephen blends pragmatic architecture with strong operational instincts to eliminate classes of failures, improve velocity, and restore actionable telemetry after alert fatigue. He’s shipped embedded SDKs and cross-site widgets at GoFundMe, built early vector-based search and recommendation systems as a founder, and contributes to well-known open-source projects like Mattermost and a rich-text AI editor. Based in British Columbia, he thrives in Staff-level IC roles where engineers own problems end-to-end and make high-impact decisions independently.
