Security Engineer - Blue Teamer

At Trezor, security isn’t a checkbox. Security has always been at the core of what we do. From day one, we understood the risks of weak security practices. That’s why we didn’t just follow standards — we helped define them. We introduced the first hardware wallet and pioneered widely adopted security features such as Recovery seeds, Passphrases, and Shamir Backup — all of which contributed to our global success.

We’re now looking for a Security Engineer - Blue Teamer. You’ll join our growing security team where your main focus is going to be monitoring and implementation (as opposed to hacking) and internal security (as opposed to product security). Outside of the team, you can expect to cooperate mainly with our brilliant IT admins.

  • Come up with your own ideas of what to monitor and implement them

  • Review vibe-coded internal apps from a security perspective

• Proficiency in English, Czech is a plus

  • Because English is the lingua franca of Trezor, while Czech is the mother tongue of most of our colleagues

• On-site presence at least twice a week

  • Because it helps in relationship building and boosts efficiency

🤝 What We Offer

• A security-first company

  • Security is not just part of the role — it is part of how Trezor thinks, builds, and operates

• Open-source mindset

  • You’ll join a company where transparency, trust, and security are not just values on paper, but part of the product and culture

• Real ownership, no corporate layers
