Responsibilities
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.
Responsibilities
Integration Planning
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.
System-Level Verification
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.
Perform regression testing following major platform, interface, application, or infrastructure changes.
Evaluate integrated system behavior against defined requirements, expected outcomes, and acceptance criteria.
Identify integration gaps and coordinate with engineering teams to determine root causes and corrective actions.
Defect & Evidence Management
Track integration defects, technical issues, and test findings through resolution.
Reproduce complex failures and coordinate troubleshooting across the engineering teams responsible for affected components.
Document test procedures, evidence, results, limitations, and residual risks.
Provide clear technical reporting on integration status, findings, blockers, and readiness.
Develop or automate repeatable integration and regression tests where practical.
Coordinate retesting and verification following defect remediation or significant system changes.
Location: This position is fully onsite in Chantilly, VA.
