Your work will empower our backend developers to build efficient APIs and enable meaningful data visualizations for users.
Key Responsibilities:
- Fetch and process blockchain data from The Graph and other sources.
- Design and implement ETL (Extract, Transform, Load) pipelines to structure raw data.
- Store and optimize data for efficient querying and API consumption.
- Identify patterns, trends, and insights from blockchain data to enhance analytics.
- Ensure data integrity, consistency, and performance in a scalable architecture.
- Work closely with the backend team to provide well-structured data for APIs.
- Optimize database performance for real-time and historical analytics.
- Implement caching, indexing, and aggregation strategies for large-scale data processing.
Required Skills & Experience:
- Strong experience with The Graph (GraphQL queries).
- Expertise in ETL processes and data pipeline management.
- Experience with data modeling and structuring for analytics & API consumption.
- Proficiency in Python, Node.js, or Rust for data processing.
- Knowledge of database management (SQL, NoSQL, time-series DBs, or data lakes).
- Ability to detect patterns and trends in blockchain transaction data.
- Experience handling large-scale datasets efficiently.
Nice to Have:
- Experience with blockchain indexing beyond The Graph (custom indexers, RPC data extraction).
- Prior experience in financial or DeFi data analytics.
- Familiarity with machine learning for pattern detection in financial transactions.
