Your opportunity:

Join our tight-knit early-stage distributed team that thrives on interesting technical challenges and building magical products that improve people's lives. As an early Data Engineer, you will work on multi-faceted data problems to enable CoinTracker to seamlessly track crypto users' portfolio & taxes.

Some projects you may work on:

• Build semi-automated systems to normalize coin symbols on every crypto exchange into a unified format

• Synchronize and process billions of price points tracking the price history of every cryptocurrency used

• Build tools to surface data integrity issues in synchronized balances, transactions, cryptocurrencies and prices

You may enjoy this role if you:

• Enjoy working with messy/unclean data from multiple sources

• Can effectively analyze + process data, and store it for use across the system, and run data integrity checks

• Can build data systems and tools, and are familiar with relational databases

• Work effectively in a remote setting and are able to overlap with our core hours of 9 AM to 12 PM PT

• Thrive in an early-stage startup environment with less stability and more ambiguity.

• Are interested in financial products and/or cryptocurrency.

Our engineering process includes:

• Code reviews.

• Continuous integration.

• Multiple daily automated deployments to production.

• Automated testing with >85% code coverage.

Some of the technical challenges we face are:

• Lots of data  — billions of data points to track transactions and market pair prices.

• Data structures & algorithms  — automated transfer detection, cost basis tracking, tax optimization, and more. Your CS fundamentals finally come in handy!

• Scalability  — some cryptocurrency users, such as algorithmic traders, accumulate millions of transactions per year. CoinTracker needs to work seamlessly for those power crypto traders.

• Blockchain  — whether it's running our own nodes, implementing xPub address generation and traversal, or parsing smart contracts to seamlessly support decentralized trading, we get our hands dirty with core blockchain technology.

• Technical complexity  — integrating with hundreds of exchanges and blockchains, and supporting thousands of cryptocurrencies means we have to methodically architect our software and build critical monitoring systems to deliver a robust and accurate platform.

Our tech stack is:

• Web: HTML, Javascript, React, CSS, Sass

• Mobile: React Native, Expo, GraphQL

• Backend: Python, Flask, GraphQL, Postgres, Redis, Python RQ

• Infrastructure: Heroku, AWS
