Senior AI Inference Engineer Model Optimization & Deployment
San Diego, CA - USA
Job Summary
The Perception team is pioneering the development of a multi-modality foundation model to drive the next generation of autonomous system intelligence.
As a Model Optimization & Deployment Engineer you will focus on bringing highly efficient production-ready large-scale models to our on-vehicle stack. We are looking for experts with hands-on experience in compressing accelerating and deploying complex models (LLMs VLMs or FMs) for power- and thermal-constrained vehicle SOCs. You will optimize the ML models write custom CUDA kernels and build highly concurrent inference code to ensure real-time deterministic execution on edge devices.
In this role you will:
- Optimize large-scale models (Multi-Modal Sensor Fusion models LLMs VLMs) using advanced quantization (PTQ QAT) pruning mixed-precision inference frameworks and parameter-efficient fine-tuning (LoRA QLoRA).
- Architect and implement model conversion and compilation pipelines using TensorRT for edge deployment.
- Perform rigorous parity checking accuracy recovery and latency benchmarking between PyTorch frameworks and compiled edge binaries.
- Develop and optimize custom ML OPs and TensorRT Plugins with efficient CUDA kernels to minimize latency and maximize memory bandwidth on AI accelerators.
- Write production-level highly concurrent and memory-safe C and CUDA code for real-time inference on vehicle systems.
Qualifications:
- Deep expertise in model quantization (PTQ QAT) and mixed-precision inference frameworks (INT8 FP8 INT4 BF16/FP16).
- Proven experience optimizing large-scale models (Multi-Modal Sensor Fusion models LLMs VLMs/VLAs) utilizing Efficient Attention mechanisms (e.g. FlashAttention Linear Attention) KV-cache optimization (e.g. PagedAttention) and Speculative Decoding.
- Extensive experience with model conversion/compilation pipelines (e.g. ONNX TensorRT ) and performing rigorous latency benchmark and model quality parity valuation.
- Proficiency in low-level programming for AI accelerators specifically developing and optimizing custom ML OPs and TensorRT Plugins with efficient CUDA kernel implementations.
- Production-level C (14/17/20) and Python programming skills with experience developing concurrent memory-safe real-time inference code for edge devices.
Bonus Qualifications:
- Familiarity with SOTA autonomous driving perception algorithms (temporal 3D object detection BEV 3D Occupancy Networks) and multi-modal sensor processing (Vision LiDAR Radar).
- Experience with distributed training pipelines and model/tensor parallelism (PyTorch Distributed Ray DeepSpeed Megatron-LM) and runtime efficiency optimization for GPU clusters.
- Experience with end-to-end autonomous driving paradigms (VLM/VLA models Foundation models) and edge deployment technologies (e.g. TensorRT-LLM).
