Other information

What's it like working at CoinTracker?
We are a fully distributed, tight-knit team spread across three countries and five cities. We have minimal process, and the majority of our time is spent working and collaborating asynchronously through tools like Github, Slack, Zoom, Asana, Notion, Google Docs, and Figma. We also stay aligned through weekly all hands, weekly goal setting, and daily standups. We aim to empower every individual on the team with full transparency, ownership, autonomy, and clear objectives.

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.

Sample projects you might work on
Implement real-time transaction synchronization with blockchains and exchanges.
Develop a smart order routing platform to enable cryptocurrency trading across exchanges, taking into account full transaction history, tax lots, fee detection, arbitrage, and slippage.
Implement tax-loss harvesting to reduce capital gains taxes for cryptocurrency users.

Last but not least, our tech stack is
Web: HTML, Java, React, CSS, Sass
Mobile: React Native, Expo, GraphQL
Backend: Python, Flask, GraphQL, Postgres, Redis, Python RQ
Infrastructure: Heroku, AWS

If this sounds exciting, we'd love to hear from you!
