About the Team:
The Robotics Technology team is a core part of Grab's long-term vision to build urban embodied AI. Our engineers take full ownership of the product lifecycle: designing and manufacturing hardware in-house, developing control and machine‑learning systems, and rigorously testing in real-world conditions and production fleet operations. This is a fast-moving, multidisciplinary environment where software, hardware and data science experts collaborate closely to solve practical challenges at scale. We are executing an ambitious growth plan to expand our robotics fleet across cities over the coming years, and we are focused on delivering highly productive, safe and efficient robot delivery services that help address current delivery labor shortages.
Based in Singapore and China, our team offers opportunities to work on cutting-edge autonomy, deploy solutions in complex urban environments, and directly influence the future of last‑mile logistics. If you're excited by tangible impact, large-scale systems and cross-functional engineering, you'll find meaningful challenges and rapid career growth here.
Get to know the role
As a Senior Perception Engineer, you will help build and ship the perception stack that turns raw sensor data into reliable, real-time understanding of the world. In our team, all engineers are expected to be hands-on across the perception stack, contributing to shipping milestones through evaluation, debugging, integration, and iterative improvements to perception algorithms and runtime behavior.
To accelerate early progress, you will take initial ownership of perception foundations: sensor integrity, calibration, and the tooling and validation workflows that ensure our perception inputs are geometrically and temporally correct. This work is a direct lever on perception quality and iteration speed. As these foundations stabilize, you will broaden into wider perception development, taking on larger slices of perception delivery over time.
You will report to the Senior Principal Perception & Prediction Engineer.
Work type: 5-day onsite.
The critical tasks you will perform
- You will ship and improve perception capabilities across detection, tracking, and multi sensor integration, using disciplined evaluation and failure analysis to iteratively raise quality and robustness.
- You will take initial ownership of perception foundations, including sensor integrity and calibration for our multi sensor suite (camera, LiDAR, radar, IMU). You will build practical diagnostics and automated checks to catch geometric or timing issues early and prevent them from being misdiagnosed as perception regressions.
- You will partner with Integration and Data and Infra teams to ensure perception is reliable in production-like conditions, including logging and replay workflows, as well as performance and latency investigations.
