Remote Senior Data Engineer - Blockchain Analytics

About the Role

We are looking for a Remote Senior Data Engineer to join our team at Nansen.ai, a leading blockchain analytics platform. In this role, you will play a crucial part in scaling our data infrastructure to meet the increasing complexity and volume of the crypto ecosystem. As a Senior Data Engineer, you will focus on data ingestion, pipeline reliability, and core datasets, ensuring that raw and processed blockchain data flows reliably and cleanly into Nansen’s core data platform.

What You'll Do

• Design, build, and scale performant data pipelines and infrastructure, primarily using ClickHouse, Python, and dbt.
• Build systems that handle large-scale streaming and batch data, emphasizing correctness and operational stability.
• Own the end-to-end lifecycle of data pipelines, from raw ingestion to clean, well-defined datasets consumed by downstream teams.
• Improve pipeline observability, data quality checks, and failure handling to ensure predictable operation at scale.
• Collaborate closely with data consumers (data engineers, product engineers, researchers) to define clear dataset contracts and schemas.
• Utilize AI tools and agents such as Cursor, MCPs, and LLMs to accelerate development, automate repetitive work, and enhance quality.
• Stay current with best practices and evolve your toolkit over time, bringing fresh thinking to the table.

Requirements

• Proven experience building and operating production data pipelines that run continuously and reliably.
• Strong data engineering and software engineering fundamentals, with deep experience in Python and SQL.
• Hands-on experience with ClickHouse and dbt in production environments.
• Solid understanding of streaming and batch ingestion patterns, including backfills, reprocessing, and schema evolution.
• Comfortable working across the data infrastructure stack: ingestion, transformation, storage, and exposure to downstream systems.
• Experience designing clean, reusable datasets intended as foundations for other teams.

What We Offer

• Competitive salary range of $120,000 - $150,000 annually.
• Fully remote work environment with flexible hours.
• Opportunity to work with cutting-edge technologies in the blockchain space.
• Collaborative and high-performing team culture.
• Access to professional development resources and training.
• Health and wellness benefits.
