🚀 In this role, you will:
  • Work at the intersection of big data, machine learning, and blockchain.
  • Co-own the product. Data is the cornerstone of CREW³. You will build, manage and scale our data stack -you will choose the right architecture and stack, and onboard other developers on them. You will have a huge impact on the CREW³ product!
  • Innovate and iterate. You’ll get to both try bold new ideas and refine & optimize the ones that work and are due for a second iteration. New ideas can include using state-of-the-art ML techniques to provide new and interesting insights about on-chain and off-chain data.
  • Tackle A+ technical problems: Work closely with product and development teams to build resilient data pipelines to process massive scales of data and provide findings to customers.
