Senior Machine Learning Engineer - Foundation Model

Premium Full-time Equities PyTorch Deep Learning Trajectory Publications 295,680 CUP
XPENG is a leading smart technology company at the forefront of innovation, integrating advanced AI and autonomous driving technologies into its vehicles, including electric vehicles (EVs), electric vertical take-off and landing (eVTOL) aircraft, and robotics. With a strong focus on intelligent mobility, XPENG is dedicated to reshaping the future of transportation through cutting-edge R&D in AI, machine learning, and smart connectivity.
We are looking for a full-time
Machine Learning Engineer
/ Research Scientist to drive the modeling and algorithmic development of XPENG’s next-generation
Vision-Language-Action (VLA) Foundation Model — the core brain that powers our end-to-end autonomous driving systems.
You will work closely with world-class researchers, perception and planning engineers, and infrastructure experts to design, train, and deploy large-scale multi-modal models that unify vision, language, and control. Your work will directly shape the intelligence that enables XPENG’s future L3/L4 autonomous driving products.

Key Responsibilities

  • Design and implement
    large-scale multi-modal architectures (e.g., vision–language–action transformers) for end-to-end autonomous driving.
  • Develop
    pretraining and fine-tuning strategies leveraging massive labeled and unlabeled fleet data (images, video, LiDAR, CAN bus, maps, human driving behaviors, etc.).
  • Research and integrate
    cross-modal alignment (e.g., visual grounding, temporal reasoning, policy distillation, imitation and reinforcement learning) to improve model interpretability and action quality.
  • Collaborate with infrastructure engineers to
    scale training across thousands of GPUs using distributed training frameworks (FSDP, DDP, etc.).
  • Conduct
    systematic ablation, evaluation, and visualization of model behavior across perception, reasoning, and planning tasks.
  • Contribute to
    model deployment
    optimization, including quantization, export, and latency–accuracy trade-offs for onboard execution.

Minimum Qualifications

  • Master’s degree or higher in
    Computer Science, Electrical/Computer Engineering, or related field, with
    3+ years of experience in deep learning research or productization.
  • Strong proficiency in
    PyTorch and modern transformer-based model design.
  • Experience in
    large-scale pretraining or
    multi-modal modeling (vision, language, or planning).
  • Deep understanding of
    representation learning, temporal modeling, and
    self-supervised or
    reinforcement learning techniques.
  • Familiarity with
    distributed training (DDP, FSDP) and large-batch optimization.

Preferred Qualifications

  • PhD in
    CS/CE/EE or related field, with 1+ years of relevant industry experience.
  • Publication record in top-tier AI conferences (CVPR, ICCV, NeurIPS, ICLR, ICML, ECCV).
  • Prior experience building
    foundation or end-to-end driving models, or
    LLM
    /VLM architectures (e.g., ViT, Flamingo, BEVFormer, RT-2, or GRPO-style policies).
  • Familiarity with
    RLHF/DPO/GRPO,
    trajectory prediction, or
    policy learning for control tasks.
  • Proven ability to collaborate cross-functionally with infra, perception, and planning teams to deliver production-ready models.
What do we provide:
  • A collaborative, research-driven environment with access to
    massive real-world data and
    industry-scale compute.
  • An opportunity to work with
    top-tier researchers and engineers advancing the frontier of foundation models for autonomous driving.
  • Direct impact on the next generation of intelligent mobility systems.
  • Opportunity to make significant impact on the transportation revolution by the means of advancing autonomous driving.
  • Competitive compensation package.
  • Snacks, lunches, dinners, and fun activities.
