Motion Planning Engineer

Company: T2 Inc.

Location: Tokyo, Japan

Employment Type: Full-time (Permanent)

Work Arrangement: Hybrid (Partial Remote Work Available)

Position Overview T2 is seeking a Motion Planning Software Engineer to develop advanced motion planning solutions for autonomous trucks.

In this role, you will design, implement, and validate motion planning algorithms that enable autonomous vehicles to navigate complex driving environments safely, reliably, and efficiently.

You will collaborate closely with engineers across Perception, Localization, Control, and Simulation to integrate planning capabilities into T2's autonomous driving system.

Key Responsibilities

• Design, develop, and optimize motion planning algorithms for autonomous trucks.
• Implement and validate planning functionality through simulation and real-world vehicle testing.
• Develop optimization-based trajectory planning solutions for complex driving scenarios.
• Collaborate with cross-functional teams on system requirements, software interfaces, and integration.
• Analyze vehicle behavior and improve planning performance, safety, and robustness.
• Diagnose and resolve issues using simulation results and real-world driving data.
• Contribute to scalable, maintainable autonomous driving software architecture.

Required Qualifications

• Professional experience developing software in C++.
• Strong foundations in engineering and mathematics.
• Knowledge or practical experience with optimization-based algorithms.
• Experience using Git or equivalent version control systems.
• Strong analytical, problem-solving, and independent engineering skills.
• Specialized knowledge in at least one of the following areas:
• Mathematical optimization, particularly nonlinear optimization.
• Trajectory prediction.
• Motion planning.
• Control engineering.
• Effective communication skills in English or Japanese.

  The Planning

  Team operates in a bilingual environment.

Preferred Qualifications

• Master's degree or PhD in Robotics, Vehicle Control, Computer Science, or a related field.
• Experience designing ADAS or autonomous driving system architectures.
• Experience developing functions such as Automated Lane Keeping Systems (ALKS), Adaptive Cruise Control (ACC), or automated lane changes.
• Experience developing software for four-wheeled vehicles, particularly heavy-duty commercial vehicles.
• Experience developing safety-critical or high-reliability systems.
• Knowledge or experience in machine learning, deep learning, or end-to-end autonomous driving systems.

Compensation and Benefits

• Estimated Annual Compensation: ¥6,000,000–¥20,000,000, depending on experience and performance.
• Performance-based bonuses twice annually.
• 20 days of paid annual leave granted upon joining.
• Flexible work arrangements under Japan's discretionary labor system.
• Partial remote work, subject to company policies.
• Social insurance, corporate defined-contribution pension, and additional employee benefits.
