Own your work. Skip the meetings. 

We’re hiring a Tech Lead — remote-first, async-first, and built for deep work.

At Koinly, we do things a little differently.

We’re remote-first, async-first, and optimized for focused development — not meetings, micromanagement, or calendar chaos. Engineers here enjoy deep ownership, real autonomy, and a codebase that reflects it: clean, well-tested, and performance-focused.

Now we’re hiring a Tech Lead to help us scale a growing Ruby microservices platform, mentor engineers, and keep our product simple, stable, and fast — even as it grows more complex behind the scenes.

This is a hands-on leadership role: you'll guide 3–5 engineers, review code, tackle tough technical challenges (especially around performance and databases), and collaborate closely with product and tech leadership.

The role

We’re looking for a sharp, self-motivated engineer who leads by example. You care deeply about performance, code quality and developer experience and you've got the experience to back it up. 

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!

What you'll do:

• Lead a team of 3–5 engineers while staying ~50% hands-on.
• Remove roadblocks and help with complex architectural work.
• Partner with product and tech leads to deliver fast, clean solutions.
• Review code, coach engineers, and uphold our standards.
• Keep our systems stable, simple, and scalable.
• Monitor and resolve production issues with confidence.

What you'll bring

• Prior team or technical lead experience - managing engineers/projects and taking responsibility for the team’s software design and delivery.

• Excellent Ruby skills and a good understanding of React.

• Demonstrable experience building scalable products using technologies such as RabbitMQ, Kafka, OLTP/OLAP databases, AWS/Heroku.

• Strong debugging and memory/speed optimization skills.

• Wish to stay hands-on in all technical aspects while leading a team of engineers.

• Strong communication and collaboration skills (both written and verbal).

• Strong attention to detail and a keen eye for code quality.

• 7+ years of coding experience.

Your first month

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. 

What you'll get

• A lean, high-trust engineering team that ships with quality.
• Full ownership and autonomy in your work.
• An async-first environment with minimal meetings.
• Time for deep work — and respect for your energy.
• Truly flexible working hours (40h/week, no more).
• USD $100–120K/year (B2B contract).
• 32 paid days off (incl. public holidays).
• Co-working space budget, if desired.
• Work on a technically rich product with real user impact.
