Senior Electrical EngineerJob ID: 2613308. Location: Crane, IN, United States. Date Posted: Jun 4, 2026. Category: Engineering and Sciences. Subcategory: Electrical Engr. Schedule: Full-Time. Shift: Day Job. Travel: Yes - 10% of the time. Minimum Clearance Required: Interim_Secret. Clearance Level Must Be Able to Obtain: Secret. Potential for Remote Work: On-Site.Job DescriptionSAIC is seeking a Senior Electrical Engineer with deep experience troubleshooting and supporting Hardware‑in‑the‑Loop (HWIL) test environments. The selected candidate will play a crucial role in the development, integration, and test of a next‑generation Hypersonic Missile System , supporting real‑time test operations, electrical diagnostics, and weapon‑system‑level performance verification.This position requires on‑site support at NSWC Crane to enable hands‑on work with lab hardware, missile subsystem interfaces, and high‑fidelity real‑time simulation equipment.Key ResponsibilitiesHWIL System Troubleshooting & DiagnosticsDiagnose and resolve issues within complex HWIL testbeds involving sensors, avionics, embedded computing, and closed‑loop weapon‑system interfaces.Identify root causes related to component failures, degraded signals, hardware performance, or timing anomalies.Conduct detailed fault isolation across interconnected hardware, simulation nodes, and networked weapon‑system components.Electrical Checkout & Hardware ValidationPerform electrical verification tasks including:Identification of loose or intermittent connectionsTroubleshooting faulty or damaged wiring/cablingEvaluating line integrity, grounding, shielding, and signal qualitySupport integration of new missile subsystems, instrumentation, and test rack hardware.Network Analysis & Weapon‑System Communication TroubleshootingAnalyze and verify complex system networks to ensure correct signal transmission, data routing, and message integrity across real‑time simulation components.Develop an operational understanding of weapon‑system networking architectures, including component interfaces, comms pathways, and timing requirements.Support protocols commonly used in real‑time missile and DoD systems (e.g., Ethernet, deterministic real‑time protocols, serial interfaces, MIL‑STD data links, etc.).Real‑Time Execution Performance AnalysisDiagnose causes of simulation overruns, delayed model execution, and desynchronization between hardware devices, sensors, and real‑time compute nodes.Monitor and analyze real‑time model execution timelines.Resolve timing issues affecting weapon‑system‑level closed‑loop simulations.Documentation, Collaboration & Lab SupportDocument troubleshooting steps, root causes, and corrective actions.Collaborate closely with system engineers, software developers, real‑time modelers, and test operators.Support test readiness reviews, lab configuration updates, and integration events for the hypersonic program.QualificationsBachelor's degree in Electrical Engineering or related hardware electrical engineering discipline.5+ years of experience working with HWIL environments, tactical hardware, or real‑time test systems.Demonstrated experience diagnosing electrical and hardware failures in complex integrated systems.Strong understanding of system networks, message flows, signal routing, and communication protocols.Experience with real‑time simulation/test frameworks (e.g., iHawk, Speedgoat, RT Linux, or similar).Ability to obtain and maintain a Secret Clearance . Interim secret required to start. SAIC will sponsor the clearance process.Ability to work 100% on‑site at NSWC Crane.Desired ExperienceNetwork+ or equivalent certification (Security+, CCNA, etc.).Experience reviewing or modifying wiring diagrams, harness documentation, and system schematics.Knowledge of avionics interfaces, deterministic timing systems, or secure DoD network architectures.Familiarity with HPC computing, MIL‑STD communication protocols, V&V and Systems Engineering processes.SAIC is an Equal Opportunity Employer.#J-18808-Ljbffr
