horizon3ai Senior Software Engineer on the Data Ingestion team builds and maintains pipelines transforming raw pentest output into structured data for the NodeZero platform. This role involves designing, implementing, and operating high-throughput ETL systems that normalize heterogeneous scan data and feed downstream systems.

Responsibilities

The Sr. Software Engineer on the Data Ingestion team builds and maintains the pipelines that transform raw pentest output into structured, queryable data across the NodeZero platform. NodeZero runs thousands of autonomous pentests — your pipelines are the first link in the chain between execution engine results and the insights customers see. You'll work on high-throughput ETL systems that normalize heterogeneous scan data, push structured findings to graph and relational stores, and feed downstream systems including Asset Inventory, reporting, and analytics.
This role reports to the Data Ingestion Engineering Manager and works alongside a small team of backend engineers including one P5 technical anchor.
Design, implement, and operate data ingestion pipelines that process pentest results at scale — scan output, discovered assets, vulnerability findings, and network topology data
Own end-to-end delivery of pipeline features: schema design, implementation, testing, deployment, and monitoring
Build and maintain ETL components in Go and/or Python that normalize heterogeneous inputs from NodeZero's execution engines
