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.
This project addresses the sim-to-real gap as in our current simulator pipeline. Closed-loop simulation systems are highly effective at generating massive amounts of diverse, high-fidelity ground truth data. However, they assume perfect perception. However, this ideal GT data does not perfectly align with the BEV feature representations extracted from real-world, noisy sensor data.
The project provides two outcomes:
Bridge Sim-to-Real Gap in Data Augmentation with Closed-Loop Simulation: By translating simulation GTs into a realistic BEV embedding space, the synthetic data becomes directly usable for training and fine-tuning BEV-based planning models.
Allow BEV Space Planning Model to be directly fine-tunable via Self-play RL: Once the sim-to-real gap is bridged in the BEV feature space, the planning models can thus be directly finetuned / post-trained in a self-play RL setting.

In this role you will work with the Scenario Simulation team in enhancing the fidelity of PLUS’ in-house simulator, with a focus on reducing the gap between simulated and real-world behavior. This includes improving the robustness of log-replay simulations, enhancing log conversion methods, and implementing features such as warm-start for varied initial conditions. You will also contribute to synthetic scenario development, including features like intelligent traffic light control, construction zone creation, and realistic agent spawning for local and highway environments. The work will help improve simulation frameworks used to validate and deploy autonomous truck systems.
Responsibilities:
Bridge the Sim-to-Real Gap: Develop and implement a translation layer that converts idealized simulator Ground Truth (GT) into realistic, "noisy" Bird’s-Eye View (BEV) embeddings.
Optimize Simulation Throughput: Research and implement a "shortcut" pipeline that bypasses slow image/LiDAR rendering to generate BEV features directly from state data.
Enable Closed-Loop Training: Integrate the translated BEV embeddings into a training pipeline to make synthetic data directly usable for planning models.
Support Reinforcement Learning: Create the infrastructure necessary for planning models to undergo self-play RL fine-tuning within the bridged BEV feature space.
