At Koinly, we're hiring a Tech Lead. This is a hands-on leadership role where you'll act as the guardian of a clean, well-tested, high-performance codebase—ensuring it remains simple, scalable, and stable in production (most of the time). You’ll lead by example: reviewing code, mentoring engineers, and solving our most complex architectural and performance challenges, especially around databases at scale.
We pride ourselves on having very high test coverage and rarely having any prod issues. Our backend follows a microservices architecture, consisting of multiple small services—primarily built with Ruby—that collectively power the user experience.
We’re a fully remote-first, async-first startup with product-market fit in a niche (and booming) domain: crypto taxes. If you value autonomy, technical excellence, and clear communication over meetings and process complexity, Koinly is the place for you.
???? We’re on a mission to make crypto taxes simple.
Since 2019, we’ve grown to 1.5M+ users by tackling one of crypto’s messiest challenges: tax reporting. Our platform helps investors stay compliant, track their assets across hundreds of wallets, exchanges, and DeFi platforms, and save hours of time. Just see what our customers have to say about us.
Behind that focus towards simplicity lies a deeply technical product, built on large-scale data processing and 900+ integrations. Our stack is Ruby-heavy, our test coverage is high, and our expectations on code quality and system performance are even higher.
We’re looking for a self-motivated individual who takes pride in their work, values high-quality code, and cares deeply about the overall application experience.
If you have a data mindset, a sharp eye for clean, scalable code, a bias for ownership, and want to work in the fast-growing crypto space, apply now!
Don’t ‘tick all of the boxes? Neither do we. We are driven by hiring not only by experience and relevance for the role but also by ambition. We celebrate anything ‘outside of the box’, so if you don’t meet all of the listed tickbox criteria, please do still apply as we’d love to hear from you.
Your first few weeks at Koinly are all about mutual discovery. You’ll receive hands-on tasks that help us understand your technical strengths and how you operate in our async-first, ownership-driven environment. At the same time, you’ll get to explore whether our way of working challenges and supports you in the right ways.
We’re big on clarity, autonomy, and getting things done — and we hold our own product to the same standards. We expect our users to get their taxes done in under 20 minutes — and we aim to build with that same focus and confidence. A good benchmark? Try Koinly yourself. If the product doesn’t click for you quickly, building it won’t be easier.
