About RivianRivian is on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract.
As a company, we constantly challenge what's possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.
Role SummaryWe are seeking a Sr. Staff Machine Learning Engineer to lead model pretraining efforts for our Large Driving Model, an end-to-end autonomy model that learns from large-scale, multi-sensor driving data.
This role is focused on building the foundation model layer for self-driving: scaling larger models, improving pretraining objectives, understanding scaling laws, and developing the distributed training systems needed to train models across massive real-world and simulated datasets.
This is an ideal role for someone excited by the intersection of large-scale ML, autonomous driving, multi-modal representation learning, and high-performance distributed training.
Responsibilities- Lead technical strategy for pretraining large-scale autonomy foundation models.
- Develop pretraining objectives for multi-sensor driving data, including camera, LiDAR, radar, maps, route, and vehicle-state inputs.
- Study scaling trends across model size, data scale, compute, sensor mix, and downstream autonomy performance.
- Build and improve distributed training workflows for large models, including FSDP, mixed precision, checkpointing, and training performance optimization.
- Partner with perception, prediction, planning, simulation, data, and ML infrastructure teams to connect pretraining progress to real autonomy outcomes.
- Develop evaluations that measure representation quality, downstream task performance, and closed-loop behavior.
- Mentor engineers and provide technical leadership on model architecture, training stability, scaling, and evaluation.
Qualifications- B.S., M.S., or Ph.D. in Computer Science, Machine Learning, Robotics, or a related field.
- 8+ years of experience building large-scale ML systems.
- Strong experience training large neural networks with distributed training frameworks.
- Deep understanding of transformers, representation learning, self-supervised learning, or foundation models.
- Strong PyTorch experience, including distributed training, mixed precision, and large-scale training pipelines.
- Strong engineering judgment and ability to lead ambiguous technical efforts from prototype to production impact.
