Kodiak's autonomy stack is built on AI that fuses diverse sensor streams into a unified, actionable understanding of the world. We are developing GigaFusionNet – a large-scale multimodal transformer that learns rich, joint representations across camera, LiDAR, and radar through attention-based fusion. We are looking for engineers to push the boundaries of how transformer architectures combine and reason over heterogeneous sensor data.This role is open to all levels – from those eager to contribute to cutting-edge research to experts driving innovation at scale.

In this role, you will:

Design and develop multimodal transformer architectures that fuse camera, LiDAR, and radar into unified representations
Research and implement cross-modal attention mechanisms, token fusion strategies, and efficient multi-stream tokenization
Build scalable training pipelines for large-scale multimodal transformers across massive real-world datasets
Explore self-supervised and contrastive pretraining objectives that learn transferable multimodal representations
Optimize transformer models for real-time inference under latency and compute constraints

What you’ll bring:

BS, MS, or PhD in AI, Computer Science, or a related field
4+ years experience with transformer architectures, particularly in multimodal or multi-stream settings
Familiarity with cross-attention, token fusion, or modality alignment techniques
Proficiency in Python and deep learning frameworks like PyTorch or TensorFlow
Strong understanding of scalable training for large models, including distributed training and mixed-precision optimization
Passion for building AI that reasons over the full breadth of sensory input to operate safely in the real world

What we offer:

Competitive compensation package including equity and annual bonuses
Excellent Medical, Dental, and Vision plans through Kaiser Permanente, Cigna, and MetLife (including a medical plan with infertility benefits)
MetLife Legal Services, Identity & Fraud Protection, Hospital Indemnity Insurance, Accident Insurance, & Critical Illness Insurance
