Over 20% of the world’s crypto assets are secured through our Ledger Nanos. Headquartered in Paris and Vierzon, with offices in UK, US, Switzerland and Singapore, Ledger has a team of more than 700 professionals developing a variety of products and services to enable individuals and companies to securely buy, store, swap, grow and manage crypto assets – including the Ledger hardware wallets line with more than 7 millions units already sold in 200 countries. At Ledger, we embody the values that make us unique: Pragmatism, Audacity, Commitment, Trust and Transparency. Hear from our employees how they shape the work we do here.

Of course, all this is backed by our hardware wallets which Ledger Live allows you to manage. This application is developed by several teams, each working on specific parts of the software. To sustain the company's growth, we are looking for a Senior Front-End Engineer to join the Wallet Experience business unit. Within the Live Hub squad, you’ll be responsible for building and maintaining the portfolio and account management UI flows.

  • Mentor and promote tech growth within the team, helping to set high standards for the team
