Posted on Thursday, March 16, 2023
OpenSea is the first and largest marketplace for NFTs, offering a diverse range of unique and verifiable digital assets backed by blockchain. We're excited about building a platform that supports a brand new economy based on true digital ownership and are proud to be recognized as Y Combinator's #3 ranked top private company.
When hiring, we look for candidates who can thrive in our culture of trust, feedback, and rapid growth. We believe that diversity and inclusivity are essential to our success, and we provide equal employment opportunities regardless of background or identity. Our opportunities support remote, hybrid, or onsite work at our offices in New York City, San Francisco, or Silicon Valley, and we're dedicated to creating an environment where all employees can do their best work and contribute to the growth of our platform.
OpenSea is looking for an experienced, entrepreneurial and web3 native analytics engineer to help build out the core data definitions of web3 and help us (and others in the broader community!) create and maintain the best abstraction tables - interpretation layer - for NFT blockchain data. This individual will work closely with our Protocol, Marketplace and Platform Engineering teams, and be an active member of the web3 data community.


  • Help build and maintain both internal and external abstractions (e.g. on Dune) for core OpenSea and Seaport data tables
  • Craft data transformation pipelines to combine various external datasets and internal datasets
  • Work closely with the Protocol team to understand and account for the implications of protocol level changes on internal and external datasets
  • Work with external analytics providers such as Dune, Nansen, Reservoir, etc. to help move us toward common standards around attribution, data accuracy, etc.
  • Create monitoring and alerting to ensure data fidelity
  • Design a thoughtful system of redundancies and checks across internal and external datasets so we can have deeper insight in data accuracy
  • Dig deep into contract calldata and be extremely detail oriented to account for the many edge cases that will crop up to ensure our on chain datasets are as accurate as possible

Desired Experience

  • 5+ years of experience in data engineering, including fluency with Python, Airflow and Snowflake
  • Ability to interpret smart contract output and work closely with blockchain engineers to understand how to extract and standardize data from different contracts
  • Crypto/web3 experience, including a love for the community, and/or a degen portfolio
  • Fluency with web3 analytics tools including making spells (DBT) in Dune and/or with Nansen/Google Bigquery
  • Experience communicating effectively up, down and sideways across the company, with thoughtfulness around optimizing asynchronous communication and tailoring communication to different preferred styles
  • Strong cross-functional skills and ability to operate under ambiguous and fast moving problem spaces
  • Humility, humor, curiosity, resourcefulness and a relentless drive to grow and learn
If you don't think you meet all of the criteria below but still are interested in the job, please apply. Nobody checks every box, and we're looking for someone who is excited to join the team.
The base salary for this full-time position, which spans across multiple internal levels depending on qualifications, ranges between $175,000 to $225,000 plus benefits & equity.
