## About the Role

* Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, or a related discipline.
 * Experience with embedded test rigs, real-time operating systems, and timing analysis tools.
 * Ability to execute tests on representative flight-hardware platforms (e.g., ARM, FPGA).
 * Proficiency with test-management tools (e.g., Jira, IBM DOORS) and maintaining traceability to system requirements.
 * Strong written and oral communication skills; ability to present test outcomes to multidisciplinary teams and senior leadership.
 * Proficiency in Python, C++, C# or MATLAB for test script development.
 * Experience with test-automation frameworks (e.g., pytest, Robot Framework, Google Test).
 * Use of Simulink/MATLAB for model-in-the-loop (MIL) and hardware-in-the-loop (HIL) testing., * Prior experience testing sensor-fusion software in aerospace or defense.
 * Knowledge of LIDAR, RADAR, EO/IR cameras
 * Experience testing sensor-tasking, prioritization, and information-value metrics.
 * Experience testing data-association techniques (nearest-neighbor, JPDA, MHT) and verifying track continuity under challenging scenarios.

## Description

* Develop Test Strategies & Plans - Create comprehensive verification and validation (V&V) test strategies for sensor-fusion software, including unit, integration, system, and hardware-in-the-loop (HIL) testing.
 * Design & Execute Test Cases - Write detailed test cases and test scripts (manual and automated) that exercise algorithm functionality, edge-case scenarios, and real-world sensor data streams.
 * Build Test Infrastructure - Implement and maintain automated test frameworks, test harnesses, and CI/CD pipelines (e.g., Jenkins, GitLab CI) to run regression suites on target hardware and simulators.
 * Perform Data Collection & Analysis - Capture sensor data, ground-truth measurements, and algorithm outputs; analyze results using statistical methods to quantify accuracy, latency, and reliability.
 * Coordinate Cross-Disciplinary Reviews - Work closely with algorithm, software, and hardware engineers to identify defects, trace requirements to test artifacts, and drive issue resolution.
 * Document Findings - Produce clear, standards-compliant test reports, defect logs, and traceability matrices that support certification and program milestones.
 * Support Continuous Improvement - Contribute to process improvements, test-procedure standardization, and tooling enhancements across the Sensor Fusion group.
