product, not internal BI.\n\nFull-stack product development: application features and integrations.\n\nRequirements:\n\nSenior or Staff level, 7+ years of commercial experience in software engineering\n\n5+ years of commercial experience with Python in production\n\nStrong TypeScript (React) skills for building application features on the frontend \n\nStrong SQL and deep understanding of databases\n\nFull-stack experience: delivering product features and integrations end to end, across backend and frontend\n\nExperience with GCP and BigQuery\n\nTrack record of building customer-facing products, not just internal tools or dashboards \n\nAbility to design engineering abstractions and discuss architectural decisions with the team, explaining trade-offs\n\nFluent English (C1) for daily communication with the US team: syncs, technical discussions and written communication\n\nNice-to-have:\n\nExperience with e-commerce and tracking analytics\n\nExperience with
