Job Summary

Kodiak Robotics Inc. was founded in 2018 and has become a leader in autonomous ground transportation committed to a safer and more efficient future for all. The company has developed an artificial intelligence (AI) powered technology stack purpose-built for commercial trucking and the public sector. The company delivers freight daily for its customers across the southern United States using its autonomous 2024 Kodiak became the first known company to publicly announce delivering a driverless semi-truck to a customer. Kodiak is also leveraging its commercial self-driving software to develop test and deploy autonomous capabilities for the U.S. Department of Defense.

Kodiaks 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 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 youll bring:

BS MS or PhD in AI Computer Science or a related field or at least 2-3 years of industry experience
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
