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.
