Join our tight-knit early-stage distributed team that thrives on interesting technical challenges and building magical products that improve peoples' lives. As an early engineer on the team, you will work on scaling our backend systems and directly own top-level product and engineering objectives.
- Build new features, products, integrations, and back-end services.
- Design scalable systems to support millions of users.
- Own and deliver on top-level product and engineering objectives.
- Collaborate with team members across the company.
- Evolve our technical architecture, infrastructure, code quality, tools, and culture to continually step up the quality and speed of our engineering systems.
This role may be a good fit if you:
- Love building great products and engineering systems.
- Have strong CS fundamentals, including algorithms, data structures, system design, and distributed systems.
- Write high quality code, value software testing, and uphold best practices in engineering, security and design.
- Enjoy designing, building, scaling, and maintaining production services.
- Have experience scaling architecture of a startup to a mid-size company.
We're looking for someone who:
- Is productive, resourceful, and an effective problem solver.
- Works effectively in a remote setting and are able to overlap with our core hours of 9 AM to 12 PM PT.
- Thrives in an early-stage startup environment with less stability and more ambiguity.
- Is 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:
- Mobile: React Native, Expo, GraphQL
- Backend: Python, Flask, GraphQL, Postgres, Redis, Python RQ
- Infrastructure: Heroku, AWS
What's it like working at CoinTracker?
We are a fully distributed, tight-knit team spread across five countries. We have minimal process, and the majority of our time is spent working and collaborating asynchronously through tools like Figma, Github, Intercom, Linear, Notion, Slack, and Zoom. We also stay aligned and bonded through two-week sprints, standups, all hands and socials. We aim to empower every individual on the team with full transparency, ownership, autonomy, and clear objectives. You can read more about the principles with which we conduct ourselves through this blog post.
If this sounds exciting, we'd love to hear from you!
