Systems Test Engineer

Systems Test Engineer IVMount Indie is seeking a Systems Test Engineer IV to lead integration, validation, and operational evaluation activities across complicated tactical communication systems. This role is responsible for reducing uncertainty through evidence generation and ensuring delivery decisions are informed by validated system behavior rather than assumptions.The Systems Test Engineer IV transforms mission intent, architectural hypotheses, and integration risks into structured validation strategies that produce actionable evidence. This role collaborates across software, networking, RF, cyber, hardware, and systems engineering disciplines to mature system readiness and support mission success.Integration and test are treated as learning activities—not cleanup phases. Successful candidates will be comfortable operating in environments where architecture evolves through experimentation, progressive integration, and operational feedback.Key ResponsibilitiesDefineContribute to Design Reference Missions (DRMs) by identifying mission-critical behaviors, operational stressors, and validation objectivesHelp translate mission intent into measurable system outcomes and readiness criteriaParticipate in identification of mission risks, integration uncertainties, and validation prioritiesDesignLead development of validation strategies aligned to mission threads, architectural intent, and system risk postureDefine integration and operational evaluation approaches that progressively reduce uncertaintyCollaborate with Systems Engineers to ensure architectural hypotheses can be validated through evidence-producing activitiesDefine test objectives, success criteria, and expected system behaviorsDe-riskLead integration, modeling, simulation, experimentation, and operational evaluation activitiesDesign learning-oriented integration events that validate or invalidate system-level assumptionsIdentify architectural gaps, interface mismatches, and operational risks through evidence-based analysisEvaluate expected versus observed system behavior and communicate resulting insightsProduce evidence-based assessments supporting system maturity and readiness decisionsCoordinate cross-discipline troubleshooting and root-cause analysis effortsDrive integration learning cycles that reduce mission and architectural uncertaintyDeliverEstablish readiness criteria supporting integration and delivery decisionsEnsure validation evidence is traceable to mission intent and operational objectivesSupport mission demonstrations, operational assessments, and customer-facing evaluationsCommunicate system readiness, residual risk, and confidence levels to technical and program leadershipRecommend delivery readiness based on evidence generated through integration and validation activitiesRequired QualificationsBachelor's Degree in Engineering, Mathematics, Physics, Computer Science, or related technical discipline, or equivalent experience8–12 years of experience supporting development, integration, validation, or operational evaluation of complicated systemsExperience leading integration and validation activities across multiple engineering disciplinesExperience analyzing system behavior and identifying integration risks through test, simulation, experimentation, or operational evaluationExperience developing validation strategies, readiness criteria, and evidence-based recommendationsDemonstrated ability to operate in iterative development environments where architecture and implementation evolve through learningStrong technical troubleshooting and root-cause analysis skillsActive U.S. Secret ClearancePreferred QualificationsExperience with tactical communications, networking, RF, SATCOM, cyber, or C4ISR systemsExperience with modeling and simulation environments supporting system validationExperience with Jira, Jama, DOORS, or similar traceability and engineering management toolsExperience supporting flight test, operational demonstrations, or military experimentation eventsExperience with digital engineering, MBSE, SysML, Cameo, or related methodologiesExperience defining readiness criteria for complex integrated systemsExperience operating in environments where integration and test are used as primary mechanisms for risk reduction and architectural learningWhat Success Looks Like (12 Months)Establishes validation strategies aligned to mission intent and architectural riskReduces late-stage integration surprises through early evidence generationImproves confidence in readiness decisions through objective validation criteriaEnables delivery decisions based on demonstrated system behavior rather than assumptionsElevates organizational integration and validation maturity through evidence-based practices
