Job description

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.
