Systems Integration & Test Engineer

We are seeking Integration & Test Engineers to plan and execute system-level integration and verification across a complex ecosystem of interconnected platforms shared services mission applications and infrastructure environments.

These engineers will focus on end-to-end system behavior across platform boundaries validating how services interfaces infrastructure and mission capabilities work together in an integrated environment. The role will span areas including identity networking APIs CI/CD observability mission hosting tenant services and hybrid infrastructure.

The ideal candidate brings strong systems-level troubleshooting skills and can work across multiple engineering disciplines to identify integration issues coordinate resolution and provide objective evidence that capabilities are ready for operational use.

• Develop integration plans for new capabilities shared services interfaces and significant platform or infrastructure changes.

• Define integration objectives test dependencies required environments and clear entry and exit criteria.

• Coordinate integration and test activities across platform application infrastructure security and mission engineering teams.

• Identify integration risks dependencies and potential failure points before changes reach production environments.

• Coordinate test sequencing and environment readiness across multiple technical teams.

• Plan and execute end-to-end tests validating service interactions across multiple platforms and technical environments.

• Validate APIs data exchanges identity flows networking CI/CD workflows observability and application dependencies.

• Support multi-tenant mission-processing and GEOINT workflow testing.
