Test Engineer

JOB RESPONSIBILITY

Electrical and Electronic System Testing:

• Lead the planning and execution of functional, performance, and reliability tests for complex electrical and electronic subsystems.
• Validate missile avionic subsystems and interface modules under operational and environmental loads (thermal, vibration, humidity).
• Interpret test data and determine conformance with performance criteria, creating actionable insights for design and production teams.
• Develop custom test setups using signal generators, spectrum analyzers, and oscilloscopes for hardware-in-loop (HIL) testing.

Circuit Design Analysis and Test Planning:

• Analyze detailed electronic schematics, including mixed-signal and embedded system layouts, to derive effective testing strategies.
• Lead efforts in signal path tracing, bus communication validation (e.g., I2C, SPI, CAN), and analog signal integrity verification.
• Propose improvements in circuit testability, suggest design-for-test (DFT) modifications, and ensure comprehensive coverage of test cases.
• Validate pin-to-pin harnesses, grounding schemes, and shielding as per aerospace and defense standards.

System/Sub-System Testing & Telemetry Validation:

• Develop end-to-end validation protocols for telemetry chains, including signal integrity verification, decoding, and data analytics.
• Execute tests aligned with MIL-STD-810, MIL-STD-461 (EMI/EMC), JSS 55555, and other defense standards.
• Lead EMI/EMC test campaigns in accredited labs and interpret results in the context of system-level performance.
• Analyze telemetry logs for fault trends, signal corruption, or performance degradation under stress conditions.
• Coordinate with embedded and RF teams to troubleshoot signal flow and hardware-data interface mismatches.
• Perform Acceptance tests and qualifications tests as per the ATP/QTP/QAP.

Troubleshooting and Root Cause Analysis:

• Lead root cause investigations using structured problem-solving tools like Fishbone Diagrams, 5 Whys, Fault Tree Analysis, and 7 QC tools.
• Resolve intermittent faults and cross-domain issues (e.g., mechanical-electrical interface failures) using multidisciplinary approaches.
• Mentor junior team members on troubleshooting workflows, escalation protocols, and safe handling of high-voltage/high-current modules.
• Interface with design and integration teams to close the loop on failure modes and improve next-gen platform reliability.

Safety Compliance and Lab Protocol Enforcement:

• Implement and enforce electrical safety policies in compliance with IEC, IS, and internal defense safety standards.
• Train team members on safe work practices including use of PPE, ESD-safe handling, and energized system interaction protocols.
• Review and approve high-risk test plans involving power modules, explosive devices (where applicable), or autonomous system activation.

Documentation and Quality Control:

• Review and approve Standard Operating Procedures (SOPs), test reports, and compliance documents for testing and validation activities.
• Ensure that test documentation meets internal QA, customer, and regulatory requirements.
• Lead document audits, manage revision histories, and support customer review processes with well-organized data packs.

Test Automation and Data Analytics:

• Design and deploy automated test benches using NI LabVIEW, Python, or MATLAB for repetitive testing and data logging.
• Implement data acquisition systems (DAQs) for real-time monitoring and logging of electrical parameters during tests.
• Leverage data analytics tools to identify long-term trends, failure patterns, and statistical deviations in subsystem performance.

Cross-functional Collaboration:

• Collaborate with Firmware, Mechanical, and RF teams to align testing methodologies and synchronize subsystem integration timelines.
• Participate in design reviews, Failure Modes and Effects Analysis (FMEA), and interface control meetings to ensure testability from design inception.
• Act as a liaison with vendors or certifying bodies during qualification, certification, or field test events.

Field Trials and Deployment Support:

• Support on-site missile system trials, including instrumentation setup, telemetry system validation, and post-trial data debriefs.
• Troubleshoot live field anomalies and coordinate with command-and-control or launch platform teams for fast turnarounds.
• Document lessons learned and feed critical insights into design iterations or system-level risk mitigation plans.
