  • Collaborate closely with the data indexing team to improve existing tooling and infrastructure, enhancing the developer experience for Ethereum projects.
  • Troubleshoot and optimize data processing workflows to enhance both reliability and performance metrics.
  • Contribute to our open-source projects, empowering other developers in the Ethereum ecosystem to leverage your work.

What We're Looking For

  • Proficiency in Python, with a strong understanding of asynchronous programming and frameworks like FastAPI.
  • Experience using web3.py to interact with Ethereum smart contracts and on-chain data.
  • Familiarity with asyncio, enabling the development of efficient data pipelines.
  • Solid problem-solving skills with a passion for optimizing data workflows for performance and reliability.
  • A proactive mindset, eager to collaborate with teammates and contribute to a dynamic, open-source environment.
  • A foundational understanding of DeFi concepts and the broader Web3 landscape.

Nice to Have

  • Experience with Docker for containerization and deployment of applications.
  • Familiarity with blockchain technologies beyond Ethereum, such as Bitcoin or other layer-1 solutions.
  • Contributions to open-source projects or a portfolio showcasing your coding abilities.
  • Knowledge of data indexing techniques and best practices in handling large datasets.

What We Offer

  • Competitive token and equity compensation, aligning your success with the company's growth.
  • Fully remote work environment, providing the flexibility to achieve work-life balance.
  • Home office stipend and a dedicated learning & development budget to support your professional growth.
  • Unlimited PTO and a conference budget, fostering a culture of continuous learning and exploration.
  • Paid team retreats to strengthen relationships and celebrate our collective achievements.
