Product Manager, Defi Integrations

Koinly
London

Shape the future of crypto tax with a product people actually need.

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.

As Product Manager for Blockchain and Defi Integrations, you’ll work at the frontier of crypto wallet and data ingestion. You’ll turn complex on-chain activity into clear, useful product improvements for Koinly users.

The role involves analysing blockchains, protocols, transaction data, user behaviour, and market signals to identify where our integrations can be stronger, then working closely with engineering to define and ship the right improvements. You’ll help decide what we build next, balancing data quality, customer impact, growth, retention, and business value. You’ll bring strong blockchain and Defi knowledge, sharp analytical ability, and practical product judgement.

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.

Read on for responsibilities, requirements, and who we are.

Role at a glance

  • Scope of role:

    • Blockchain and DeFi integration coverage.

    • On-chain data quality and correctness.

    • Integration-driven growth and retention.

  • Team: Product

  • Report to: Product Lead

  • Location: Ideally, you’re based in Europe or a Europe-friendly timezone.

  • Employment: B2B

    • 32 holidays per annum (incl. public holidays)

    • ‍Co-working space budget if desired

  • Visa sponsership: No

What you’ll be doing

  • Own integration coverage and data quality.
    You’ll identify where blockchain and Defi imports are missing, incomplete, or confusing, then define the expected behaviour and work with engineering to ship improvements that users can trust.

  • Turn user signals into product priorities
    You’ll prioritise Defi integrations using customer feedback, product insights, and business priorities to decide what we build next. You’ll make trade-off calls and ensure work is ready to ship.

  • Stay close to the market
    You’ll stay close to on-chain data, market trends, competitor coverage and user demand. You’ll use those inputs to help decide which integrations, fixes, and quality improvements Koinly should prioritise next.

Core skills

  • Can analyse and parse blockchain and Defi protocols
    You’ve gone deep on protocols, not just used them. You can read a whitepaper and explain how Pendle separates principal and yield, or how Hyperliquid PnL settles.

  • Can build exceptional products
    You know what good looks like. You have built standout products that turn complex technical problems into simple user experiences.

  • Knows the space
    You’ve worked in or close to the space and know the landscape: who’s building what, and how the major ecosystems differ.

Standout abilities

  • Analytical and precise
    You take a rough idea and make it actionable. You read API docs and JSON responses and figure out what’s signal, what’s missing, and what we need to do about it.

  • Comfortable making decisions that move product and growth metrics
    You think in funnels and cohorts. When you propose work, you can explain what you expect it to move and why.

  • Strong written communication and engineering partnership.
    You turn difficult investigations into one-page specs engineers can build from without translation. You hold your own in technical conversations and act as the voice of the product inside the team.

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

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.

  • An async-first environment with minimal meetings.

  • Truly flexible working hours (40h/week, no more).

  • 32 paid days off (incl. public holidays).

  • Co-working space budget, if desired.

  • Work on a technically rich product with real user impact.
