Robotics Validation Engineer | C++ Framework Developer

Jul 2021 – Aug 2024 · 3 yrs 1 mo · Bengaluru, Karnataka, India

Framework Engineering: Designed and developed modular C++11/14 and Python-based validation frameworks to verify safety-critical autonomous system logic; refactored legacy codebases using Smart Pointers and STL containers, improving memory safety and reducing runtime overhead across 5+ modules.
Nav2 Stack Validation: Engineered end-to-end validation scenarios for the ROS2 Nav2 navigation stack, covering Behavior Tree orchestration, costmap inflation layers, and path-planner robustness; performed performance tuning for DWB local and NavFn global planners to achieve smooth, collision-free obstacle avoidance.
ROS2 System Integration: Validated ROS2 node-to-node communication pipelines and data integrity across middleware layers; monitored real-time system latency and message-passing reliability using RVIZ2, ensuring stable operation of autonomous navigation components under dynamic load conditions.
Perception & Computer Vision Testing: Integrated YOLOv8-based object detection and Stereo Vision benchmarks into the validation pipeline to evaluate 3D spatial awareness accuracy; assessed perception robustness across varied lighting and dynamic obstacle scenarios in autonomous driving environments.
Automated Test Suites: Built comprehensive automated test suites using Pytest and Google Test (GTest), achieving 100% logic coverage for safety-critical autonomous modules; reduced manual testing effort and enabled continuous regression testing within the Agile CI/CD pipeline.
Functional Safety & Standards Compliance: Conducted functional validation aligned with ISO 26262 (ASIL) and NCAP safety standards; verified system-level behaviors including Autonomous Emergency Braking (AEB) and Lane Keep Assist (LKA) against regulatory requirements, ensuring full compliance before release.
Awards: Contextual Master Award - recognized for aligning technical frameworks with complex business requirements. On-the-Spot Award - for agility in resolving critical software bottlenecks.
