For hazardous journey. Small wages, bitter cold, long months of complete darkness, constant danger, safe return doubtful. Honour and recognition in case of success.\nFridtjof 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.\nNansen is the onchain analytics platform traders and funds use to see what's actually happening on-chain. We label and track 500M+ blockchain addresses, the largest such dataset in the industry.\nOur mission: Surface the signal and create winners.\nThis seat also comes with a defined runway: you'll start as an IC, with a clear path to Engineering Manager within 12-18 months for the right person.\nWhat you'll do at Nansen\nYou'll work with data engineers and ML engineers to build the data infrastructure that powers Nansen's customer-facing analytics product.\nDesign, build, and scale data pipelines and infrastructure in ClickHouse, Postgres, Python, and dbt\nRun the pipelines behind 500M+ labeled addresses, moving terabytes of streaming and batch data every day\nPartner with crypto researchers, software engineers, and product to shape how data gets modeled, surfaced, and productized\nOwn data quality, reliability, and observability end-to-end. At most analytics companies a wrong number is a support ticket. Here, it's a position someone took.\nMentor other data engineers and raise the technical bar across the team\nUse AI tools and agents to move faster and cut the busywork out of your day\nWhat we're looking for\nYou've shipped and scaled high-performance data systems in production\nDeep expertise in SQL and Python, with real hands-on experience in dbt, ClickHouse, and Postgres\nStrong grasp of streaming data architectures, comfortable operating at genuine scale\nYou work the full data stack: ingestion, transformation, storage, modeling, serving\nYou already build with tools like Cursor, Claude Code, and MCPs\nYou write clearly. This team is remote and async, so most decisions get made in writing\nBonus: experience leading or managing projects in a smaller team, fluency in onchain data structures, Web3 technologies, and crypto markets\nWhat we offer our crew\nCompetitive salary. Meaningful equity. Real ownership in what you build\nFully remote with support for in-person co-location\nAnnual company retreat and team off-sites in Singapore, Bangkok, or Oslo, with flights and accommodation covered\nUnlimited AI tokens\nYour own OpenClaw for work\nNansen Pro account: full access to the most detailed onchain data in the market\nSpeed, ownership, curiosity, courage, transparency, simplicity\nA front-row seat (and a hand in building) the next chapter of finance\nWork visa sponsorship is not provided for this role.\nSafe return doubtful.
