Crypto Backend Engineer

We’re Trezor, the company that invented the world’s first hardware wallet and a leading name in crypto security. Founded in 2013 and still 100% self-owned, we build open-source products that help more than two million people across 200+ countries secure their digital assets.

As a Crypto Backend Engineer, you’ll work on the infrastructure connecting Trezor Suite to blockchain networks and crypto data services — powering everything from account discovery and transaction history to fee estimation, token metadata, and transaction broadcasting.

You’ll build services that stay reliable even when blockchain nodes, RPC providers, or third-party APIs don’t. You’ll own your work end to end, influence architecture and observability, and help shape the long-term direction of Trezor’s blockchain infrastructure.

You don’t need to know every blockchain we support on day one. What matters is your ability to understand unfamiliar systems, investigate how they behave under failure, and turn that knowledge into reliable production software.

If this sounds like the kind of infrastructure you’d like to own, keep reading.
