About this role

We’re a team of experts pushing the limits of what’s possible, united by our common goal to unlock true freedom through digital ownership, making technology accessible for all. We believe in a world where users, creators and enterprises manage their value with ownership and freedom. Our curiosity drives us to innovate, empowering individuals on a global scale. We believe change is constant and our team moves forward as one, with a culture of problem-solving where every employee is empowered and supported to challenge tradition and create solutions. Our mission is simple: to make self-custody accessible and give people the keys to their own financial futures. If you want to make a true impact, we want you to join us at Ledger.

At Ledger, we’re proud to be the global platform for digital assets and Web3, with over 20% of the world’s crypto assets secured through our Ledger devices. With our headquarters in Paris, and offices in Vierzon, Grenoble, Montpellier, London, Portland, Geneva, Zurich and Central Singapore, we have a team of around 600 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 7.5 millions units already sold in 200 countries.

The team

You will join the Security Operations team, which is responsible for protecting Ledger’s corporate, cloud, SaaS, and data center environments. Its mission is to anticipate, detect, investigate, and respond to cyber threats—including monitoring, alert triage, incident response, detection, visibility, automation, exposure tracking, and continuous process improvement. This scope is distinct from that of the Donjon (product security): SecOps covers the operational security of internal environments, the cloud, endpoints, workloads, identities, and infrastructure.

As a close-knit and experienced team—technically rigorous and committed to knowledge sharing—we are also continuously building the SOC itself: integrating new log sources, ensuring data quality, expanding detection coverage, and developing reliable dashboards and operational workflows.
