Frontend Staff Engineer

Koinly is a successful product used by crypto investors around the world, helping them make sense of complex portfolios and tax obligations across chains, wallets, exchanges, and Defi protocols. 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.

We're looking for a Frontend Staff Engineer to take deep ownership of our data platform - the engine behind products at the intersection of crypto, finance, and tax. You'll work across a modern React web application and a high-performance distributed data-processing backend, with a new React Native mobile app joining your scope in the future.

This is a senior, hands-on role for someone who combines exceptional engineering craft with genuine product ownership. We expect you to lead by example: writing high-quality code, making sound architectural decisions, and raising the bar for the entire frontend team.

We’re 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.
