Proton.ai via Greenhouse
Own and expand Proton.ai's unified Data Layer, including medallion-style raw, refined and curated layers, ingestion and transformation pipelines, serving interfaces and reconciliation of messy multi-protocol customer data. Ensure data correctness and reliability, use AI-native engineering workflows and partner with backend, AI and product teams.
7+ years of data engineering experience with production ownership; strong programming and SQL skills; ability to analyze query plans and debug performance; orchestration and ELT experience; cloud data warehouse and cloud platform experience; ingestion from files, events and APIs; expertise in consistency, idempotency, backfills and schema drift; daily use of agentic development tools such as Claude Code, Cursor or Codex; strong ownership, judgment, startup communication and English C1+. Streaming, lakehouse or medallion architectures, ERP or ecommerce data and data for AI or ML are advantages.
Remote work for the supported regions; end-to-end ownership of the Data Layer; AI-native engineering environment using modern coding agents; direct collaboration across backend, AI and product.
