Help the team get better through code review and design discussions

Requirements

8+ years building software, ideally touching a few different areas (not just one stack forever)
You actually understand how browsers work. DOM APIs, the event loop, how SPAs route, why CORS exists. Not just "I used React."
You’ve built browser extensions before. You know the content script/background script split, message passing, manifest v3 limitations.
Strong TypeScript. Comfortable in Python. Willing to write Rust (or already do).
You’ve dealt with data at scale: event streaming, pipelines, high-throughput ingestion.
Backend basics: APIs, Postgres, Elasticsearch, Kafka or similar.
Can work without someone telling you what to do next.
