Senior Typescript Engineer (Exchange Data Team)
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!

In the fast-paced crypto ecosystem, APIs, regulations, and data structures constantly evolve. Our customers rely on Cryptio for reliable, real-time data syncing across exchanges, custodians, and financial systems.
