Job Summary
Build the interface for crypto tax compliance
Koinly helps people do their crypto taxes without losing their minds. The bar is simple to describe and hard to deliver: a user should be able to reconcile thousands of transactions and file their taxes in under 20 minutes.
In this role the frontend isnt just a skin for an API. Its where the tax logic meets the user. You wont just be styling buttons; youll be building a high-performance interface that handles massive datasets and complex DeFi reconciliations.
Were a remote-first async-first startup with deep product-market fit. If you value autonomy technical excellence and clear communication over meetings and process complexity Koinly is the place for you.

Responsibilities
Own frontend features end-to-end: From scoping and architecture to shipping and iteratingwithout 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 doesnt make sense for the user or the implementation.

Contribute to technical direction: Have a voice in architecture decisions tooling choices and code standards.
Requirements
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 dont 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.
Dont tick all of the boxes Neither do we
Were driven by hiring not only by experience and relevance but also by ambition. We celebrate anything outside of the box so if you dont meet every single listed criterion please do still applywed 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 isnt good enough; your TS skills should reflect that.
Deep React experience. This is a Senior level role. You should have a deep understanding of Reacts internals performance optimization and modern tooling. We need someone who can hit the ground running with a complex established codebase.
