Data Platforms Software Engineer, Senior

We build software that helps cyber operators and analysts make sense of fragmented, high-volume data. As a Senior Software Engineer, you'll focus on backend services and production data pipelines for cyber platforms. You'll improve systems already in use and develop new cyber capabilities. You'll own services and data pipelines from design through deployment and production support. Working directly with operators, analysts, and other engineers, you'll clarify requirements and decide how data is ingested, modeled, transformed, stored, and made available to applications.

For example, you might build a pipeline that brings together network, endpoint, and other operational data whose formats and schemas change over time, then design the validation, transformation, and recovery mechanisms that keep that data usable when individual sources fail or change.

Define a testing strategy around important product behavior and the impact of failures, choosing where unit, integration, and end-to-end tests provide the most useful evidence. Design and build a maintainable testing framework and reusable Python tooling using established testing libraries. Integrate automated checks into CI/CD workflows and keep feedback fast and reliable enough for daily development. Create representative test data, reproducible test environments, and diagnostics that help engineers reproduce failures and distinguish product defects from test, data, or environment problems.

Report what was validated, what failed, and where meaningful gaps remain so engineers have a clear view of product quality. Establish testing patterns that other engineers can use and extend through code reviews, worked examples, and documentation of key technical decisions.
