Senior Blockchain Data Engineer: NLP & ETL Pipelines (Remote)

Unchain Data; Northern (KY); Hybrid; USD 130,000 - 190,000; Full time

Job summary

Inca Digital, a veteran-owned data and intelligence company, is seeking experts to design and operate end-to-end ETL/ELT pipelines and NLP-LLM processing over unstructured text. You will build production-grade APIs, dashboards, and automated alerts by sourcing data from databases, APIs, files, blockchain nodes, and social feeds.

Join a remote-first team collaborating with R&D, data scientists, and investigations to translate intelligence requirements into scalable client-facing products,

Qualifications

• Advanced Python and SQL.
• Production ETL/ELT pipelines with orchestrators (Airflow, Dagster, Prefect, Step Functions) including backfills, idempotency, retries, schema drift, and on-call.
• Hands-on with PostgreSQL/RDS and object storage (S3).
• Serving data to consumers: APIs (Kong OSS, FastAPI) and dashboards.
• Docker, Git, CI/CD (GitHub Actions, AWS CodeBuild/CodePipeline), and IaC (Terraform, CDK).

Responsibilities

• Design, build, and operate end-to-end batch and incremental ETL/ELT pipelines, turning raw data into production-grade APIs, dashboards, and automated alerts.
• High-throughput data acquisition from diverse sources: relational databases, third-party and vendor APIs, flat files, blockchain nodes and indexers, and social and web text at scale.
• NLP and LLM-assisted processing over unstructured text — entity and claim extraction, classification, deduplication, and enrichment feeding downstream risk models.
• Model and query data across relational, object, and graph (Neo4j) stores, choosing the right one for the access pattern rather than defaulting to a favorite.
• Provenance and reproducibility: raw captures immutable, datasets versioned, and any published finding reproducible as of the date it was made.
• Data quality as a first-class deliverable: validation, lineage, reconciliation, and freshness monitoring.
• Partner with the Head of R&D, engineers, data scientists, and our investigations team to translate intelligence requirements into scalable client-facing products.
• Contribute to technical design and architecture in a written, argued design process.
