Job Description


CryptoTrader.Tax is the leading tax reporting platform for cryptocurrency investors. Today, users leverage the platform to connect their exchanges, wallets, and crypto accounts to automatically pull in their transaction history and generate necessary tax reports with the click of a button.

CryptoTrader.Tax has tens of thousands of users all over the world, has processed more than fifty billion dollars in cryptocurrency transactions, and has partnered up with some of the largest cryptocurrency exchanges and tax software companies in the industry—including Intuit TurboTax—in effort to bring seamless crypto tax reporting to the mainstream.

Our Team

We're an ambitious, young, and agile team with a vision of building an essential piece of infrastructure for the future of digital assets. We work very hard, and we have a lot of fun doing it. 

The company is headquartered in Kansas City, MO; however, true to the ethos of the crypto culture in which we operate, our team is fully distributed with teammates in Austin, St. Louis, Portland, Los Angeles, Mexico City, Zagreb, and more.

The Opportunity

CryptoTrader.Tax’s mission is to enable seamless tax reporting for all crypto investors—no matter how complex their transaction history. To help achieve this, we are looking to bring on highly technical software engineer who is extremely familiar with DeFi protocols and public blockchains to create a brand new DeFi team.

You will have enormous responsibility in this role, as the need for DeFi tracking and capital gains tracking has exploded. The blockchain and DeFi integrations you will work on will enable hundreds of thousands of crypto traders and yield farmers to seamlessly import their transaction history.

You will be one of the very first hires for this new DeFi team and contributing to one of the most important pieces of infrastructure for the future of the cryptocurrency industry.
