Senior Principal Planning & Control Engineer

Get to Know the Team

Our team develops production-grade robotics and autonomy capabilities for the uniquely complex unstructured urban environments of Southeast Asia. We are ambitious and pragmatic: 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 the Senior Principal Planning & Control Engineer you will be the technical anchor and visionary for motion planning and control. You will architect design and deliver the systems that allow autonomous platforms to navigate safely smoothly and predictably in complex urban environments. This is a hands-on role with broad technical ownership setting direction and standards for planning and control while driving the development of production-grade solutions.

You will report to the Head of Engineering and will contribute directly to both technical and strategic leadership. This is a fully onsite role at Grab Singapores One North office.

The Critical Tasks You Will Perform

Technical Leadership & Strategy

• Own the technical vision and roadmap for motion planning and control from behavioral planning through trajectory generation and vehicle actuation.
• Architect a scalable production-grade planning and control stack tailored to the challenges of Southeast Asian environments.
• Lead technical design reviews and set the standard for developing verifiable and safety-critical software regardless of the underlying methodology.

Hands-on Development & Implementation

• Lead development of planning algorithms for real-time online replanning including behavior selection constrained optimization trajectory generation and interaction-aware motion planning.
• Develop robust control algorithms to ensure vehicle stability comfort and safety under real-world constraints.
• Develop high-fidelity simulation and validation frameworks to rigorously test and harden the planning and control modules.
• Own the lifecycle of algorithms: specification design implementation testing (simulation SIL/HIL) and deployment.

Mentorship & Collaboration

• Mentor senior engineers; set the bar for design reviews experimentation hygiene and operational excellence.
• Partner with technical anchors in Perception Prediction Mapping and Vehicle Integration to deliver a cohesive autonomy stack.
• Translate advances in planning and control into robust production-grade systems.
