Sr. Machine Learning/AI Engineer
About Rivian
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.
About the Role
Qualifications
Hands-on experience with quantized model deployment, ML design stacks, and code generation for embedded or heterogeneous compute systems.
Strong understanding of computer vision models (e.g., object detection, segmentation) and their optimization for edge inference.
Proficiency in deep learning frameworks (e.g., PyTorch, TensorFlow) and their low-level IRs or export formats (e.g., ONNX).
Solid programming skills in C++, Python.
Familiarity with CUDA/OpenCL (or other accelerator programming models).
Preferred Qualifications
Prior experience working with hardware-software co-design, especially for autonomous or robotics platforms.
Deep knowledge of numerical precision trade-offs, quantization-aware training (QAT), and dynamic/static quantization flows.
Familiarity with embedded real-time constraints and hardware profiling/debugging tools.
Familiarity with rearchitecting models to best suit hardware capabilities.
Publication record in top-tier ML/Systems conferences (e.g., MLSys, NeurIPS, DAC, ICCAD).
Responsibilities
Lead the development of optimizations for mapping quantized perception models (e.g., CNNs, Transformers, LLMs) to embedded and heterogeneous hardware platforms.
Design and implement hardware-aware optimizations, including quantization strategies, model compression, memory-efficient representations, and operator fusion, targeted to custom accelerators.
Collaborate with hardware teams to co-optimize model architecture and compute pipeline under real-time constraints (latency, throughput, power).
Benchmark and analyze system performance across platforms and iterate to achieve optimal deployment efficiency.
Partner with perception, systems, and autonomy teams to align model optimization efforts with hardware roadmap and real-world autonomy requirements.
