Job Description

Senior AI/ML Engineer

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

Job Requirements

  • 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

Benefits

  • 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
