Lead Calibration

About Grab and Our Workplace

Grab is Southeast Asia's leading superapp. From getting your favourite meals delivered to helping you manage your finances and getting around town hassle-free, we've got your back with everything. In Grab, purpose gives us joy and habits build excellence, while harnessing the power of Technology and AI to deliver the mission of driving Southeast Asia forward by economically empowering everyone, with heart, hunger, honour, and humility.

Get to Know the Team

Our team develops production-grade robotics and autonomy capabilities for the uniquely urban environments of Southeast Asia. We are advancing perception, planning, and control step by step, with safety evidence as the gate for every milestone. We focus on building robust system capabilities, scaling with uncompromised quality, and collaborating with industry leaders while investing in in-house expertise where it differentiates us.

We are a senior, hands-on engineering group that prizes operational excellence, clear interfaces, and reproducible pipelines.

Get to Know the Role

As a Lead Calibration & Tooling Engineer, you are the foundation of our robotic platform's perception and localization systems. Your mission is to lead the end-to-end processes that ensure every sensor sees the world with geometric precision and temporal alignment. You will build the automated systems and tools that allow us to calibrate, monitor, and maintain a fleet of complex robots at scale, directly allowing the success of our downstream algorithms.

You will report to a Head of Engineering, work onsite in Grab One North, Singapore office, and contribute directly to both technical and strategic leadership.

The Critical Tasks You Will Perform

• Oversee, operate, and improve the end-to-end calibration pipelines for our multi-sensor suite (camera, LiDAR, radar, IMU), from initial bring-up to fleet-wide maintenance.
• Lead the development of automated tooling to detect and correct for sensor drift in the field, ensuring system integrity and reliability over time.
• Architect and build the diagnostic and visualisation tools that empower perception and localization engineers to debug complex geometric and temporal issues.
• Integrate calibration and configuration management workflows into our core CI/CD and on-platform testing processes.
• Define and monitor quality metrics and readiness gates for safe rollouts, partnering with Perception and Localization teams to ensure data integrity.

What Essential Skills You Will Need

• Bachelor's of higher Degree in Robotics, EE, CS, or a related field, or equivalent 5 years+ practical experience.
• Experience with designing, building, and shipping production-grade calibration systems for complex, multi-sensor robots.
• Background in multi-sensor calibration (camera-LiDAR, camera-camera, radar-camera/LiDAR, IMU fusion) with hands-on experience in intrinsic and extrinsic calibration methods.
• C++ and Python programming skills.
• Knowledge of time synchronisation and the ability to design automated calibration pipelines.
• Experience with building diagnostic and visualisation tools for sensor alignment and debugging.

A big plus if you have:

• Experience with fleet-scale calibration challenges, such as online monitoring and drift detection.
• Experience with time synchronisation protocols and techniques.
• Proficiency with relevant libraries and tools (e.g., OpenCV, PCL, CeresSolver, ROS/ROS 2).
• Familiarity with factory and production-line calibration processes.
