AI Summary

Builds and maintains a simulation engine for autonomous truck perception validation, designing ML workflows for scenario generation and extending software for behavior, pathfinding, and vehicle dynamics.

About this role

PlusAI is a Physical AI company pioneering AI-based virtual driver software for factory-built autonomous trucks. Headquartered in Silicon Valley with operations in the United States and Europe, Plus was named by Fast Company as one of the World’s Most Innovative Companies. Partners including TRATON GROUP’s Scania, MAN, and International brands, Hyundai Motor Company, Iveco Group, Bosch, and DSV are working with Plus to accelerate the deployment of next-generation autonomous trucks. If you’re ready to make a huge impact and drive the future of autonomy, Plus is looking for talented individuals to join its fast-growing teams.

About the role:
The Scenario Simulation team is responsible for building a simulation engine that simulates the systems downstream of the perception system. The team works on realistic actor behaviors and other infrastructure tooling for generating diverse scenarios to validate Autonomy. You will have an opportunity to drive immediate user value while architecting advanced, AI-powered frameworks for long-term safety validation.

Responsibilities:

  • Design scalable ML workflows for generating AV scenarios - ranging from traffic simulations to synthetic scenario creation from a natural language specification.

  • Contribute to tooling for migrating scenario creation using the traditional approach to AI-based scenario understanding and validation

  • Own the development and upkeep of the simulation framework, driving its reliability and performance to unblock all technical stakeholders.

  • Collaborate directly with internal customers and partner teams to provide solutions for their test creation workflows.

  • Have an opportunity to tackle simulation and autonomy evaluation challenges across various areas of the autonomy system, including motion planning, mapping, Controls.

  • Create and extend software for behavior, pathfinding, road networks, spatial queries, collision detection, vehicle control, vehicle dynamics, etc.

    • Required Qualifications:

  • MS or higher degree in Computer Science, Machine Learning, or related field

  • Good development skills in modern C++ and Python

  • Proficiency in ML libraries and experience in transformer and diffusion architectures

  • Basic understanding of generative models

    • Desirable Qualifications:

  • 2+ years of Industry experience in ML and C++ software

  • Familiarity with AV simulation environments and driving datasets
