What we're seekingA visionary Machine Learning Engineer to join our founding team who will help bridge the gap between high-level AI research and real-world physical actuation for our next-generation autonomous transport platforms. We are actively hiring across three core specialized subcategories: AI Research, Post-Training Optimization, and Data Engineering.
AI Researcher (World Models & VLA)What you'll do- Research and develop cutting edge RL and distillation techniques for trajectory planning
- Integrate emerging research from the broader AI community, identifying and prototyping the most promising solutions
- Design and deploy end-to-end multimodal models that translate real-time visual perception and high-level behavioral goals into physical vehicle actuation
- Develop interactive world models from raw multi-sensor logs, allowing the team to re-simulate events and query what a vehicle would see if it altered its trajectory
- Ensure core autonomous driving models can seamlessly adapt to novel urban environments and edge cases
- Partner with validation and QA teams to run model releases through rigorous simulated scenarios, detecting regressions and identifying systemic performance bottlenecks.
What we're looking for- 4+ years of non-internship professional MLE experience.
- Deep expertise in applying AI Transformers to robotics, physical actuation, or spatial-temporal data.
- Proven track record designing or training multimodal systems, large-scale VLA models, or generative Diffusion models.
- Strong background in Sensor Fusion, combining inputs from Cameras, LiDAR, and Radar.
- Fluency in PyTorch or JAX for training large-scale models.
- Experience with multi-task learning, Birds-Eye-View (BEV) frameworks, representation learning, or data tokenization is highly preferred.
- Proficiency in Python and familiarity with C++.
Post-Training & OptimizationWhat you'll do- Own the post-training lifecycle by distilling, quantizing, and optimizing massive models to run with low latency on vehicle edge hardware.
- Profile real-time inference pipelines to identify and eliminate CPU, GPU, and memory bandwidth bottlenecks on the vehicle.
- Work with low-level hardware, electrical, and firmware teams to iterate on custom carrier boards, sensor interfaces, and GPUs on edge devices.
- Benchmark and deploy models utilizing hardware-accelerated runtimes (e.g., TensorRT, CUDA) to minimize inference times under strict constraints.
What we're looking for- 4+ years of non-internship professional MLE experience.
- Strong background in machine learning engineering with a focus on model optimization, distillation, and deployment.
- Hands-on experience optimizing models for edge deployment or custom embedded GPU targets.
- Deep understanding of profiling tools and debugging resource constraints across CPU/GPU boundaries.
- Experience with modern deep learning frameworks (PyTorch or JAX) and runtime compilation.
- Robust programming skills in Python and C++.
- Familiarity with low-level camera/sensor interfaces and robotics hardware is a significant plus.
Data & Long-Tail ScenariosWhat you'll do- Architect automated pipelines to ingest, filter, and identify rare, high-value, and long-tail scenarios out of multi-petabyte multi-sensor datasets.
- Target and extract complex structural corner cases from real-world driving logs to continuously feed, challenge, and improve our end-to-end behavior models.
- Iterate closely with QA, testing, and simulation teams to transform ambiguous real-world anomalies into concrete data blocks for simulation testing.
- Implement programmatic data curation, active learning strategies, and statistical quality metrics to optimize the signal-to-noise ratio of our training pipelines.
What we're looking for- 4+ years of non-internship professional MLE experience.
- Professional experience building data curation pipelines, active learning workflows, or data mining architectures for massive physical datasets.
- Strong familiarity with robotics data structures and spatial frameworks, including Birds-Eye-View (BEV) or spatial tokenization.
- Experience processing and structuring raw data from Cameras, LiDAR, and Radar.
- Expert-level proficiency in Python, data engineering frameworks, and PyTorch/JAX.
- Exceptional ability to navigate, structure, and derive signal from highly ambiguous, messy, or undefined real-world data distributions.
