The role

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 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.

Our mission: Surface the signal and create winners.

This 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.

What you'll do

You'll work with data engineers and ML engineers to build the data infrastructure that powers Nansen's customer-facing analytics product.

Design, build, and scale data pipelines and infrastructure in ClickHouse, Postgres, Python, and dbt
Run the pipelines behind 500M+ labeled addresses, moving terabytes of streaming and batch data every day
Partner with crypto researchers, software engineers, and product to shape how data gets modeled, surfaced, and productized
Own 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.
Mentor other data engineers and raise the technical bar across the team
Use AI tools and agents to move faster and cut the busywork out of your day

What we're looking for

You've shipped and scaled high-performance data systems in production
Deep expertise in SQL and Python, with real hands-on experience in dbt, ClickHouse, and Postgres
Strong grasp of streaming data architectures, comfortable operating at genuine scale
You work the full data stack: ingestion, transformation, storage, modeling, serving
You already build with tools like Cursor, Claude Code, and MCPs
You write clearly. This team is remote and async, so most decisions get made in writing
