About Cryptio

Cryptio is building the data infrastructure for the crypto economy. Our enterprise-grade back-office platform helps businesses and institutions automate financial reporting and compliance for digital assets—so they can navigate the crypto space with confidence. Backed by top investors like Point Nine, 1kx, and BlueYard, we’ve raised $26M and work with industry leaders like Circle, Uniswap, and even the Government of El Salvador. Currently, we are a team of 80 amazing people. Crypto needs better infrastructure to go mainstream—and we’re here to build it!

Location

At Cryptio, we’re a remote-first team, with most working 100% remotely, while others enjoy a mix of office time in our hubs in London or Paris.

We're looking for someone who has

• 3+ years of experience as a Frontend Software Engineer

• Proficiency in React and TypeScript

• Some experience with CSS frameworks (we use Tailwind and Emotion)

• Some experience with frontend end-to-end testing frameworks (we use Jest and Playwright)
