About the Company

Gemini is a global crypto and Web3 platform founded by Cameron and Tyler Winklevoss in 2014, offering a wide range of simple, reliable, and secure crypto products and services to individuals and institutions in over 70 countries. Our mission is to unlock the next era of financial, creative, and personal freedom by providing trusted access to the decentralized future.

Build and maintain scalable, efficient, and reliable ETL/ELT pipelines using languages and frameworks such as Python, SQL, Spark, Flink, Beam, or equivalents
Work on real-time or near-real-time data solutions (e.g. CDC, streaming, micro-batch) for use cases that require timely data
Partner with data scientists, ML engineers, analysts, and product teams to understand data requirements, define SLAs, and deliver coherent data products that others can self-serve
Establish data quality, validation, observability, and monitoring frameworks (data auditing, alerting, anomaly detection, data lineage)
Investigate and resolve complex production issues: root cause analysis, performance bottlenecks, data integrity, fault tolerance
Document data flows, data dictionaries, architecture patterns, and operational runbooks

Deep expertise in Python and SQL writing production-quality, maintainable, testable code
Experience with large-scale data warehouses (e.g. Databricks, BigQuery, Snowflake)
Solid grounding in software engineering fundamentals, data structures, and systems thinking
Hands-on experience in data modeling (dimensional modeling, normalization, schema design)
Experience building systems with real-time or streaming data (e.g. Kafka, Kinesis, Flink, Spark Streaming), and familiarity with CDC frameworks
Experience with orchestration / workflow frameworks (e.g. Airflow)
Familiarity with data governance, lineage, metadata, cataloging, and data quality practices

Preferred Qualifications:

Experience with crypto, financial services, trading, markets, or exchange systems
Experience with blockchain, crypto, Web3 data — e.g. blocks, transactions, contract calls, token transfers, UTXO/account models, on-chain indexing, chain APIs, etc.
Experience with infrastructure as code, containerization, and CI/CD pipelines
