Lead Edge AI Engineer

Life at Grab

At Grab, every Grabber is guided by The Grab Way, which spells out our mission, how we believe we can achieve it, and our operating principles - the 4Hs: Heart, Hunger, Honour and Humility. These principles guide and help us make decisions as we create economic empowerment for the people of Southeast Asia.

Get to know the Team

The Data Science (Geo Vision) team at Grab focuses on improving the maps and building map-based intelligence such as localization, routing, travel time estimation, and traffic forecasting. We use Computer Vision and conventional machine learning methods on a variety of signals-specifically utilizing edge device footage-to understand our locations and road networks.

Get to know the Role

We are looking for a Lead Data Scientist / Edge AI Engineer to lead edge development for our edge devices. A key focus will be Multi-Task & Action Recognition Development, where the successful candidate will be responsible for developing and refining multi-task learning models and video action recognition systems for our edge devices.

You will work onsite and will report to the Head of Data Science based in the Cluj Office.

The Critical Tasks You Will Perform

• Multi-Task & Action Recognition Development: Develop and refine multi-task learning models (specifically Hydranet architecture) and video action recognition systems using PyTorch.
• Edge Deployment & Engineering: Deploy Computer Vision algorithms into embedded Android platforms, utilizing the Qualcomm SNPE / QNN SDK to interact directly with the DSP.
• Resource Efficiency: Conduct rigorous performance analysis to reduce power consumption and manage thermal constraints. You will ensure model switching latency remains minimal to maintain recording integrity.
• System Stability: Implement safety mechanisms to ensure system stability during dynamic model graph reconfiguration.
• Collaboration: Collaborate with Firmware and Mobile teams to integrate signals for model decision-making.

What Skills you will Need:

• Educational Background: Bachelor's degree or higher in Computer Science, Electrical Engineering, or a related field.
• Experience: Minimum of 5 years of experience in computer vision and machine learning, with a mandatory focus on Edge AI deployment and optimization.
• Mandatory Frameworks: Deep expertise in PyTorch. You must be proficient in Video Action Recognition and Learning network design.
• Edge Constraints: Deep understanding of resource-constrained environments (memory bandwidth, thermal management and power consumption).
• Optimization: Knowledge of general model optimization techniques for edge devices (quantization, pruning, graph splitting).
• Communication: Proficiency in English (speaking and writing) with the ability to present technical data insights.

The Nice-to-Haves:

• Context-Aware DSP Optimization & Dynamic Graph Execution: Experience designing and implementing intelligent runtime management logic (dynamic model switching or conditional computation) on Android to dynamically load/unload specific heads of multi-task architectures (e.g., Hydranet) on the Qualcomm Hexagon DSP.
• DSP & SNPE Expertise: Proven experience with Qualcomm DSP (Hexagon), SNPE (Snapdragon Neural Processing Engine), or QNN SDK.
• Android Development: Background in Android development for edge devices, particularly in handling hardware-software interactions and resource utilization.
• Sensor Fusion: Experience with camera localization and motion estimation using a combination of GPS, IMU, video, and magnetometer.
• Core CV Skills: Experience with advanced computer vision techniques, including camera localization, motion estimation, and 3D reconstruction.
• System-Level Software: Proficiency in low-level system software and hardware-software interactions on Qualcomm chipsets.
