Company mission
To provide a secure and compliant cryptocurrency tax solution, giving peace of mind and confidence in tax reporting.
Role
Who you are
- Experience: 8+ years with a focus on complex, data-heavy web applications
- 8+ years of frontend experience: You have a proven track record of shipping complex SaaS products
- Expert-level TypeScript: You reach for strong typing instinctively, not as an afterthought
- Deep React experience: Expert knowledge of React and modern frontend tooling (Vite, ESLint, testing frameworks, etc.)
- Self-starter mindset: You are comfortable with ambiguity, can define your own next steps, and don't need a detailed spec to get started
- High standards: You care deeply about readability, correctness, and long-term maintainability
- Shipping velocity: Proven ability to ship fast without accumulating crippling technical debt
- Product instincts: You think about the user experience, not just the code implementation
- Remote-first: Experience working effectively in a remote, async-first team
- We're driven by hiring not only by experience and relevance but also by ambition. We celebrate anything ‘outside of the box’, so if you don’t meet every single listed criterion, please do still apply—we’d love to hear from you
- That said, there are two hard gates for this role:
- Expert-level TypeScript. You should reach for strong typing instinctively, not as an afterthought. We deal with complex financial data where "mostly correct" isn't good enough; your TS skills should reflect that
- Deep React experience. This is a Senior level role. You should have a deep understanding of React’s internals, performance optimization, and modern tooling. We need someone who can hit the ground running with a complex, established codebase
What the job involves
- Own frontend features end-to-end: From scoping and architecture to shipping and iterating—without waiting to be told what to do next
- Write clean, well-structured TypeScript: Produce code that your teammates are proud to review and that follows best practices
- Make pragmatic technical decisions quickly: Know when to go deep into a problem and when to move fast to hit a deadline
- Proactive maintenance: Identify and fix pain points in the codebase. If you spot something broken or brittle, you fix it
- Product collaboration: Work closely with product and design, but push back when something doesn't make sense for the user or the implementation
- Set the bar for quality: Maintain sensible abstractions and avoid unnecessary complexity to ensure long-term maintainability
- Contribute to technical direction: Have a voice in architecture decisions, tooling choices, and code standards

Our take
Trading cryptocurrencies has become a lucrative profession for many investors, but one that is difficult to remain compliant within. The nature of the assets leads to constant price fluctuations and trading of many cryptocurrencies spread across multiple wallets, and its decentralised nature makes this activity difficult to track and analyse for tax calculations.
Koinly provides a tax management platform for cryptocurrency traders, allowing users to import cryptocurrency transaction records directly from ledgers, and aggregate it all into a tax report. The platform also helps users to track their portfolios, ROI, and capital gains within a minimalist dashboard, helping them to identify how to reduce taxes for the next year.
Many different cryptocurrency platforms aim to help traders analyse markets and make smart investment decisions, but the complications of tax reporting for crypto remain untackled. Koinly has recognised this gap in the market, claiming that its platform helps reduce the amount of time and money it takes to produce a crypto earning tax report, whilst identifying tax issues and ultimately ensuring compliance.
