Position Summary We're building safety first video telematics products (ADAS/DMS/driver behavior analytics) that run efficiently on edge devices inside commercial vehicles.

You will write modern C++ software, integrate and optimize CV/ML pipelines, and ship reliable, low latency perception features such as driver monitoring and distance estimation from camera feeds.

Key Responsibilities

• Own C++ software modules for on device video capture, preprocessing, inference, and post processing on Linux.
• Implement classical image processing pipelines (denoise, resize, color space, undistortion) and CV algorithms (keypoints, homography, optical flow, tracking).
• Build and optimize distance/spacing estimation from monocular/stereo camera(s) using calibration, geometry, and/or depth- estimation networks.
• Integrate ML models (PyTorch/TensorFlow - ONNX/TensorRT/NNAPI/NPU runtimes) for DMS/ADAS events: drowsiness, distraction/gaze, phone- usage, smoking, seat belt, etc.
• Hit real time targets (FPS/latency/memory) on CPU/GPU/NPU using SIMD/NEON, multithreading, zero copy buffers.
• Write clean, testable C++, CMake builds, and Git based workflows (branching, PRs, code reviews, CI).
• Instrument logging/telemetry; debug with gdb/addr2line, sanitize and profile with perf/valgrind.
• Collaborate with data/ML teams on dataset curation, labeling specs, training/evaluation, and model handoff.
• Work with product & compliance to meet on road reliability, privacy, and regulatory expectations.

Qualifications

• B.Tech/B.in CS/EE/ECE (or equivalent practical experience).
• 2-3 years in CV/ML or video- centric software roles.
• Hands on in modern C++ on Linux, with strong Git and CMake.
• Solid image processing and computer- vision foundations (camera models, intrinsics/extrinsics, distortion, PnP, epipolar geometry).
• Practical experience integrating CV/ML models on device (OpenCV + ONNX Experience building real time pipelines for live video (GStreamer/FFmpeg, RTSP/RTMP, ring buffers), optimizing for latency & memory.
• Competence in multithreading/concurrency, lock free queues, and producer-consumer designs.
• Comfort with debugging & profiling on Linux targets.

• Hardware acceleration (GPU/VPU/NPU, Arm NEON/DSP), YOLO/RT DETR/Lightweight backbones on edge.
• Cross compiling, Yocto/Buildroot, containerized toolchains; unit tests (gtest), static analysis (clang tidy, cppcheck), sanitizers.
• Basic familiarity with MQTT/IoT, message schemas, and over the air updates.
