Job description

The Opportunity

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.

What You'll Work On

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.

You Have

4+ years of experience with professional software engineering including building, shipping, and supporting production software 3+ years of experience developing backend software in Python, including services, APIs, or data-processing components 2+ years of experience building and operating production data pipelines, including ETL/ELT workflows, data validation, and failure recovery 2+ years of experience building, deploying, or operating software on a cloud platform such as AWS 2+ years of experience owning technical delivery for a service, data pipeline, or product feature, including clarifying requirements, making design decisions, and supporting production systems Experience with SQL and relational databases, including data modeling, schema design, transformations, and query optimization Experience using Docker or container tools, automated testing, and CI/CD workflows to deliver production software Ability to obtain a TS/SCI clearance with a polygraph Bachelor's degree in a technical field such as Computer Science, Computer Engineering, or Information Systems

Nice If You Have

Experience building software for cyber operations or working with operational data such as logs, network telemetry, endpoint data, or security events Experience working with workflow orchestration, event streaming, or distributed data-processing systems Experience building frontend applications with modern frontend technologies such as React or TypeScript Experience building data services or integrations for AI-enabled or LLM-based applications deployed to users Experience supporting defense, intelligence, national security, or research and development customers
