Senior AI/ML Engineer

Remote Europe | Remote Asia

Talent Wanted. For hazardous journey. Small wages, bitter cold, long months of complete darkness, constant danger, safe return doubtful. Honour and recognition in case of success.

Fridtjof Nansen crossed the Arctic, going places no human had ever been. Together with our users, we're doing the same onchain: charting entirely new territory.

Nansen is a special company. We're building the single best product for onchain investing, allowing A New Way To Trade that's agentic, onchain, and fully integrated.

If you're looking for an adventure, you've come to the right place.

Our mission: Surface the signal and create winners.

What you'll do at Nansen

You'll build the intelligence layer that powers that mission. That means working with 500M+ labeled blockchain addresses, training models on data no one else has, and shipping AI/ML systems that help real investors make better decisions and grow their portfolios.

  • Design and build AI/ML models on top of the richest onchain dataset in the world — then make them fast, scalable, and production-ready
  • Work shoulder-to-shoulder with engineers and product to ship models that actually reach users
  • Stay ahead of the curve in both AI/ML and blockchain — this space moves fast, and we need someone who moves faster
  • Level up the team: mentor junior engineers, raise the bar on what good looks like
  • Own your work end-to-end; from data pipeline to deployed feature

What we're looking for

  • You've shipped AI/ML at production scale — you have the scars and the portfolio to prove it
  • Deep fluency in frameworks around Python, Generative AI and agents
  • Deep expertise in LLMs, agent architectures, prompt engineering, and context engineering — across OpenAI, Anthropic, and beyond
  • You can work the full data stack: feature engineering, pipelines, model serving. Data engineering experience is a genuine edge
  • You don't just use AI as a tool. You think with it. AI-first isn't a checkbox, it's how you work
  • Bonus: you know onchain, you care about crypto, and you have opinions about where this is going

What we offer our crew

  • Competitive salary. Meaningful equity. Real ownership in what you build
  • Fully remote with two no-meeting days a week — because deep work doesn't happen in a Google Meet
  • Annual company retreat and team off-sites in one of our offices: Singapore, Bangkok, London, and Oslo — flights and accommodation covered
  • Unlimited AI tokens: Claude, OpenAI, whatever helps you move fast
  • Your own OpenClaw for work
  • Nansen Pro account: giving you full access to the most detailed onchain data in the market
  • A team that started as data engineers and data scientists. Your craft is respected here.
  • Speed, ownership, curiosity, courage. These aren't values on a wall — they're how we run.
  • A front-row seat (and a hand in building) the next chapter of finance

Work visa sponsorship is not provided for this role.

Safe return doubtful. Honour and recognition in case of success.
