Ledger manufactures hardware wallets and operates a Web3 custody platform with 7.5M+ units sold across 200 countries. The tech stack reveals a company transitioning from pure hardware toward data-driven operations: Snowflake, dbt, Airflow, and Tableau form a modern analytics backbone, while infrastructure spans Kubernetes, Docker, and Proxmox to handle distributed custody and blockchain integration. Hiring skews engineering-heavy with active blockchain protocol integration and data-pipeline scaling work, suggesting Ledger is automating operational friction (manual workflows, outdated docs) and building institutional-grade infrastructure for enterprise adoption.
