Product Specialist DeFi

Product Specialist DeFi at Koinly

Shape the future of crypto tax with a product people actually need. Koinly helps investors handle their taxes without losing their minds. Our goal is simple to describe but incredibly hard to deliver: a user should be able to complete their taxes in under 20 minutes.

Achieving that speed requires obsessive accuracy. As a Product Specialist DeFi, you’ll get your hands dirty in the data: moving beyond just identifying bugs to truly understanding the "why" behind transaction mechanics, liquidity pools, and API discrepancies.

We are a remote-first, async-driven team that values technical excellence and autonomy over meetings and process. If you’re analytical, technical, and genuinely curious about the inner workings of blockchain, you’ll fit right in.

🚀 Work within one of the most rapidly growing industries in the world

What you’ll own

You’ll be the bridge between our users and our developers, ensuring our product remains the most accurate in the market. In practice, that means you’ll:

• Understand and solve user problems: Gather feedback to spot opportunities, dive into reported issues to find root causes, and help the support team tackle complex cases.
• Shape the product: Work with the product team to refine strategy based on user insights and competitor research.
• Ensure data accuracy and integration quality: Investigate transaction data for errors or inconsistencies and collaborate with devs to improve our integrations.
• Test and refine features: Perform thorough QA on new features before release to ensure they meet user expectations and catch bugs.
• Organize workflows: Use AI tools to automate processes and maintain a high-quality Jira board so developers can work efficiently.

What success looks like (early)

Within 30-90 days you should:

• Understand the product deeply enough to identify the top friction points for users.
• Be fully operational in investigating data discrepancies and API issues.
• Have successfully tested and helped ship improvements to our core integrations.

The Benchmark: You should be able to use Koinly yourself for complex portfolios; if you can’t map the journey, it’s hard to fix it for others.

This role is a fit if…

You have:

• Deep Crypto expertise: You understand liquidity, DAOs, transaction mechanics, and the broader blockchain ecosystem. At Koinly, we’re truly passionate about the crypto space, so a genuine interest in crypto—beyond just Bitcoin—is a big plus.
• Analytical & technical skills: You can analyze complex data and have a basic understanding of how to use APIs.
• A Meticulous Eye: You have a high bar for quality and a "detective" mindset when it comes to QA and testing.
• Tool proficiency: You are comfortable with Jira, Excel, block explorers, and using AI tools to amplify your productivity.
• Communication: Fluent English and the ability to translate technical issues into actionable insights for cross-functional teams.
• Collaboration: Ability to work closely with cross-functional teams, including developers, customer support, and product managers.
• Adaptability: Willingness to learn quickly and navigate a fast-paced, evolving industry.

Nice-to-haves

• Experience working with RPC nodes and/or GraphQL.
• Programming experience (Python, JavaScript, etc.).
• Knowledge of Solidity or other blockchain languages.

✔️ 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.

That said, there is one core requirement for this role to ensure you can hit the ground running:

• Deep Crypto Fluency: You must have a hands-on understanding of transaction mechanics, liquidity pools, and how blockchains actually work. If you’ve never used a block explorer or handled a DeFi swap, this won't be the right fit.

About Us

At Koinly, we are building software to help crypto investors stay compliant with their tax obligations and keep track of their investments. We launched the first version of our platform in 2019 and have since grown to over 1.5M users by solving a highly technical problem and saving our users countless hours of work (see what our customers say). All of this with a small team of super-intelligent and dedicated individuals!

Our values & work environment

As a startup, we value efficiency above all else. Our team structure is flat and focused where every individual has a critical role that directly impacts our users. You will not find any middle managers or pointless meetings here. Our environment is best suited for people who are hands-on, like to take ownership, and most importantly, are self-learners.

Our team is based in Europe, so we try to work in the UK timezone, but are flexible. Everyone is expected to work 40 hours and no more. We highly value people who can prioritise their work, know what tools to use to work efficiently and can set up processes to amplify the impact of their time.

• 🏡Fully remote role (with flexible work hours)
