Job description

Reporting to the CEO directly, you are responsible for developing and optimize cutting-edge autonomy technologies for our next generation vehicle product.

As a venture-backed startup, we are pioneering the next generation of autonomous driving with AI-Defined Vehicles - a leap beyond the latest software-defined vehicles. Our mission is to build the world's most intelligent autonomous vehicle that caters to your every need, before you even know it.

We are looking for a Sr. Machine Learning Engineer to develop and optimize cutting-edge autonomy. If you have industry experience and are passionate about pushing the boundaries of machine learning, LLM/LVMs, and autonomous systems, we want you on our team.

Role Description

  • Develop, fine-tune, and optimize deep learning systems for autonomy, perception, and decision-making.
  • Research and implement multi-modal AI systems, combining vision, language, and reinforcement learning.
  • Enhance self-supervised and semi-supervised learning methods for training models on large-scale driving data.
  • Collaborate with software, simulation, and cloud engineering teams to deploy ML models into production-grade autonomy stacks.
  • Design and maintain scalable data pipelines for ingesting and processing sensor fusion data (LiDAR, radar, cameras).
  • Optimize model inference for real-time performance on embedded and cloud-based platforms.
  • Conduct model evaluations, performance tuning, and failure analysis to improve robustness and generalization.

Qualifications

  • Industry (non-academic) experience is required, post graduation.
  • 3+ years of experience in machine learning, deep learning, or AI engineering.
  • Expertise in LLM/LVM model architectures, training techniques, and fine-tuning.
  • Strong background in autonomous systems, reinforcement learning, or robotics.
  • Hands-on experience with computer vision for perception tasks (e.g., object detection, segmentation, sensor fusion).
  • Proficiency in Python, TensorFlow, PyTorch, and deep learning frameworks.
  • Experience with AWS (S3, EC2, SageMaker, Lambda, etc.) for ML training and deployment.
  • Knowledge of data engineering practices for large-scale ML pipelines.
  • Strong algorithmic and problem-solving skills, with experience optimizing models for embedded and cloud-based environments.
  • Experience working with autonomous driving stacks.
  • Familiarity with distributed training, federated learning, and on-device AI optimization.
  • Exposure to self-supervised learning, generative AI, and multi-modal architectures.
  • Understanding of simulation environments for AI model validation.
  • Knowledge of automotive systems and functional safety requirements is preferred.

Why work at thirdspacemotors.com

  • Startup environment in the heart of Silicon Valley – fast-paced, high-ownership culture.
  • Cutting-edge tech: Working on next-gen EV + autonomous driving from concept to mass production.
  • Cross-functional impact: Engineers will touch hardware, software, integration, and validation across the entire vehicle.
  • Remote/hybrid policy: not specified; likely on-site given the hands-on nature (vehicle testing, HW/SW integration).
  • Perks: Not disclosed, but typical of early-stage startups: equity, direct impact on product direction, and the opportunity to shape a new automotive brand.
