About the Position
Blockchain Data Analyst & Researcher
Lukka is seeking a Blockchain Data Analyst & Researcher to join our team in India (Remote). In this role, you will be a pivotal force in our data intelligence efforts, primarily serving as a blockchain data protocol researcher. Your core mission will involve a deep dive into the complex internals and mechanics of various blockchain networks, reverse engineering of sophisticated Decentralized Finance (DeFi) protocols, and translating these complex systems into actionable, structured data.
Responsibilities
- Maintain an AI-native and blockchain-forward mindset: Proactively leverage emerging trends and generative technologies to stay at the vanguard of the crypto revolution while maximizing work efficiency and uncovering novel, high-alpha data opportunities.
- Architect Intuitive Data Models: Turn the messiness of on-chain data into elegant, unified abstractions. Build the models that provide our users with granular, high-integrity insights across various protocols.
- Deconstruct DeFi Mechanics: Get under the hood of DeFi protocols. Reverse-engineer smart contracts and on-chain events, translating complex interactions into clean, production-grade SQL/dbt models.
- Scale Our Ecosystem Coverage: Lead the charge in indexing new blockchains. Design the schemas that transform raw chain data into our internal "source of truth," ensuring every block is captured with 100% accuracy.
- Engineer Signal from Noise: Define the metrics that matter (TVL, Volume, Fees). Be the gatekeeper of data quality, proactively identifying and filtering out wash trading, bot activity, and Sybil attacks.
Requirements
- Experience:
- 3+ years hands-on in Data Science, Data Engineering, or a hybrid role.
- Blockchain or crypto analytics background strongly preferred, familiarity with on-chain data structures, transaction semantics, and asset classification.
- Streaming & Lakehouse:
- Apache Flink or Spark Streaming for building and operating real-time data pipelines.
- Apache Iceberg or Apache Hudi for managing large-scale Data Lakehouses with schema evolution, time travel, and ACID guarantees over petabytes of raw blockchain data.
- AWS Data Platform:
- S3 for scalable data lake storage.
- RDS for structured relational workloads.
- Spark SQL and PySpark for interactive querying and ad-hoc analysis.
- Caching & Distribution:
- Familiarity with Data Grid technologies (e.g., Hazelcast, Apache Ignite, Redis) for high-throughput, low-latency data access patterns.
- Languages & Tooling:
- Advanced SQL query writing, window functions, query plan analysis, performance tuning at scale.
- Python Pandas, Polars for data wrangling.
- Scikit-learn for model development.
- Proficient in architecting high-throughput ingestion pipelines that leverage external data sources REST/WebSocket APIs, JSON-RPC node queries.
- Strong grasp of ETL fundamentals (extract, transform, load), including managing schema mismatches between heterogeneous sources and destinations.
- Engineering Mindset:
- Systematic approach to debugging: reproducing issues, isolating root cause, validating fixes.
- Comfortable working with large, semi-structured, or undocumented data sources.
Nice to Have
- Experience with Apache Ignite and Redis.
- Familiarity with REST/WebSocket APIs and JSON-RPC node queries.
