We are seeking an experienced Software and Systems Development Engineer to support the design, development, deployment, and ongoing maintenance of a new Test Framework - a purpose-built test orchestration and asset management platform operating within a classified development environment. Team member will work as a part of the engineering team, contributing across the full software development lifecycle of the Test Framework and its operational use.

The Test Framework is a distributed system that manages physical and virtual test infrastructure, orchestrates test execution, and stores and analyzes test results. It operates in an isolated environment with strict controls - creative problem-solving and debugging within those constraints is expected. The devices under test are embedded Linux systems operating in a physical lab network, so familiarity with embedded systems and networking is directly applicable.

Clearance Requirement : TS/SCI (no polygraph required)

→Design and implement new features across all Test Framework subsystems: Test Manager (configuration, orchestration, results) and Asset Manager (reservation, configuration, tasking, device adapters)
→Define and implement service APIs using IDLs
→Develop and maintain device adapters that abstract physical lab hardware (test devices, traffic generators, packet switches, optical switches) behind generic interfaces, including adapters for embedded Linux devices accessed over the network
→Implement and maintain datastores across multiple database technologies, e.g., PostgreSQL, GraphDB, DynamoDB
→Deploy and manage the Test Framework using Amazon CDK
→Develop and maintain CI/CD pipelines in Amazon Pipelines and Gitlab Pipelines
→Instrument and monitor services with CloudWatch, time series databases, and other alerting tools
→Produce and maintain technical documentation
→Provide technical support and guidance to users of the Test Framework
