We are seeking a Systems Test Engineer – Diagnostics / BIT (Part-Time) to support our customer in Crane, Indiana. This position supports the development, integration, test, evaluation, and sustainment of diagnostic and Built-In Test (BIT/BITE) capabilities for mission systems and Electronic Warfare-related platforms. The role is focused on helping ensure systems are testable, supportable, diagnosable, and ready for operational use.

This part-time position is ideal for an experienced engineer who can provide focused technical support in diagnostics, test execution, troubleshooting, and sustainment-related engineering efforts. The successful candidate will work across hardware, software, and subsystem interfaces to support fault detection, failure isolation, system readiness, and overall maintainability in laboratory and field environments.

This role requires in-person support. 

Duties:

• Support the design, integration, evaluation, and sustainment of BIT/BITE and diagnostic capabilities for mission systems, subsystems, and associated test assets.
• Analyze system requirements and help translate them into testable diagnostic functions, verification methods, and maintainability support features.
• Support laboratory and field testing activities, including test setup, execution, troubleshooting, discrepancy documentation, and post-test analysis.
• Investigate system failures, anomalies, false rejects, and BIT-related issues to identify root causes and recommend corrective actions.
• Support engineering reviews of hardware, software, and firmware changes to assess impact on testability, maintainability, and system readiness.
• Assist in development and execution of unit, integration, system, and regression testing related to diagnostics and BIT functions.
• Support activities related to FMECA, FRACAS, reliability growth, maintainability demonstrations, and technical feedback analysis.
• Work with engineering, software, logistics, and test teams to improve fault isolation, troubleshooting processes, and corrective action closure.
• Contribute to technical artifacts such as test plans, procedures, reports, discrepancy records, engineering recommendations, and support documentation.
• Support interface analysis and system integration efforts to ensure BIT functions properly across system components and operational configurations.
• Assist in maintaining configuration-controlled technical data associated with diagnostic functions, test procedures, and sustainment changes.

Desired Education:

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Systems Engineering, Electronics Engineering, or a related technical discipline.

Desired Experience:

• 3+ years of professional experience in test engineering, systems engineering, diagnostics, hardware/software integration, or related technical work.
• Experience supporting system-level troubleshooting, integration, and test for electronic, RF, software-enabled, or mission-critical systems.
• Understanding of system interfaces, diagnostic methods, fault isolation, and testability concepts.
• Experience developing or executing technical test procedures and documenting results, failures, and corrective actions.
• Ability to analyze technical data and communicate findings clearly through written reports and verbal briefings.
• Strong problem-solving skills and ability to work effectively across multidisciplinary teams.

Preferred Qualifications:

• Experience with BIT/BITE, built-in self-test, health monitoring, fault detection, or automated diagnostics.
• Experience with FMECA, FRACAS, ESS, qualification testing, PRAT, or maintainability demonstrations.
• Experience supporting mission systems, EW systems, tactical systems, radar, RF systems, or defense electronics.
• Familiarity with software/firmware verification, hardware-in-the-loop testing, or embedded system test support.
• Experience supporting engineering change reviews, configuration management, or discrepancy resolution workflows.
• Ability to work in secure lab environments and support field or range test events as required.
• Eligibility to support higher-classification tasking as required by assignment.

Work Schedule:

This is a part-time position intended for an experienced engineer who can provide high-value technical support on a flexible or reduced-hour basis. Work schedule and hours will be based on program needs and may include support for test events, troubleshooting, documentation, and technical reviews.
