Your mission:

Join our close-knit, early-stage distributed team, where we tackle complex technical challenges and build transformative crypto products that give people peace of mind. As a Staff Backend Engineer, you will play a critical role in shaping our backend architecture, scaling our systems, and driving high-impact engineering and product initiatives. You'll work cross-functionally to influence technical direction and mentor engineers, helping us build a world-class engineering team.

What you will do:

• Architect and scale backend systems to support millions of users and transactions.
• Lead and drive critical technical projects, ensuring long-term scalability, performance, and reliability.
• Design and optimize complex data processing pipelines, distributed systems, and APIs.
• Collaborate cross-functionally with Product, Design, and other teams to align technical execution with business objectives.
• Mentor and guide engineers, fostering technical excellence and best practices across the team.

What we look for:

Role-agnostic

• Impact: Demonstrated ability to drive business impact
• Mission alignment: Hungry and motivated about making progress towards our mission of Enabling everyone in the world to use crypto with peace of mind.
• Trust: Say what you believe. Do what you say.
• Communication: Able to clearly talk about the details and also zoom out to the bigger picture

Role-specific

• 8+ years of backend engineering experience
• Strong CS fundamentals, including algorithms, data structures, system design, and performance optimization.
• Deep knowledge of backend technologies, including databases, orchestrators, messaging systems, data pipelines, and more.
• Track record of technical leadership, leading complex projects, mentoring engineers, and setting engineering standards.
• Experience with large-scale data ingestion and processing systems.
• Drawn to an early-stage, high-growth startup environment with less stability and more ambiguity.
• [Bonus] Experience in crypto or financial systems.

Sample projects you might work on:

• Scale our data ingestion and computation platform to handle millions of transactions efficiently
• Build a smart trade insights platform that recommends trades across exchanges, factoring in transaction history, tax lots, fee detection, arbitrage opportunities, and slippage
• Integrate the latest country-specific tax regulations to deliver accurate, compliant tax reports for users

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
• Product challenges  — building a consumer finance product that works flawlessly for our global user base and through our partner integrations with top crypto exchanges, marketplaces and tax-filing software

Our tech stack is:

• Web: HTML, Typescript, React, React Native, Styled-Components
• Mobile: React Native, Expo, GraphQL
• Backend: Python, Flask, GraphQL, Postgres, BigTable, Redis, Python RQ
• Infrastructure: GCP, Terraform, PostgreSQL, Docker, Pub/Sub, Datadog, PagerDuty

You don’t need to know any or all of these, but be willing to learn!
