Senior Software Security Engineer

Founded in 2014, Ledger is the global leader of security solutions and infrastructure for cryptocurrencies and blockchain applications, with more than 4 million users in 180 countries.

Ledger combines hardware and software expertise to secure billions of dollars worth of almost 2,000 different crypto assets - worldwide, 15% of these assets are managed through the Ledger ecosystem.

Bolstered by accelerated growth (with revenue growing by 6 times between the first semesters of 2020 and 2021), and a new fundraiser that made Ledger a “unicorn” worth 1.5 billion dollars, Ledger will be a major player in the fourth industrial revolution - the revolution of the Internet of Value, Web3, DeFi, and NFTs.

Ledger designs the most reliable and user-friendly solutions: their R&D team created an operating system, integrated into the Nano S and X, and a platform, Ledger Live, that allows users to take back control of their digital lives by acting as a secure gateway to the entire ecosystem of digital assets. Ledger has already welcomed more than 330 people in 2021 - and they’re just getting started. Based in Paris, Vierzon, Singapore, New York, London, Geneva, Montpellier and Grenoble, upon arriving at Ledger employees sign a “P.A.C.T” of values: Pragmatism, Audacity, Commitment, Transparency and Trust
