Machine Learning Engineer Quantization Jobs (NOW HIRING)

Company:
Qualcomm Technologies, Inc.
Job Area:
Engineering Group, Engineering Group > Machine Learning Engineering
General Summary:
About the Role
Join the Qualcomm AI Hub team and help developers integrate machine learning into their products and experiences: https://aihub.qualcomm.com/.
In this role you will develop tools to help developers optimize and deploy machine learning models on edge and mobile hardware. AIMET is Qualcomm's open-source library for state-of-the-art model quantization, and compression techniques. You will develop and support cutting-edge model optimization workflows - pushing the boundary of what's possible on resource-constrained hardware. Applications range from quantizing large language models (LLMs) and generative AI models to compressing latency-critical vision, audio, and multimodal networks for deployment on Qualcomm Snapdragon and other edge SoCs.
For this role we are seeking a talented and motivated Staff Software Engineer with expertise in the optimizing and deploying ML models - especially for edge devices.
What You'll Do

• Design, develop, and maintain quantization algorithms and compression pipelines within the AIMET framework (PTQ, QAT, mixed-precision, AdaScale etc.)
• Implement advanced quantization techniques including weight-only quantization, activation quantization, KV-cache quantization, and sub-4-bit quantization for LLMs and generative AI models
• Build tooling to analyze, profile, and debug model accuracy degradation caused by quantization
• Integrate AIMET workflows with popular ML frameworks - PyTorch and ONNX
• Develop APIs and developer-facing tooling to make AIMET accessible and easy to use for external customers and design partners
• Integrate AIMET in AI Hub Workbench Quantize job to enable Quantization at large scale.
• Own end-to-end quantization and optimization of models published on Qualcomm AI Hub, ensuring they meet accuracy, latency, and power targets on Qualcomm hardware
• Quantize and validate a broad range of model families - vision transformers, LLMs, diffusion models, speech, and multimodal architectures - for deployment via AI Hub
• Develop and maintain automated quantization pipelines and evaluation harnesses to scale model onboarding across AI Hub's growing model catalog

Minimum Qualifications:
• Bachelor's degree in Computer Science, Engineering, Information Systems, or related field and 4+ years of Hardware Engineering, Software Engineering, Systems Engineering, or related work experience.
OR
Master's degree in Computer Science, Engineering, Information Systems, or related field and 3+ years of Hardware Engineering, Software Engineering, Systems Engineering, or related work experience.
OR
PhD in Computer Science, Engineering, Information Systems, or related field and 2+ years of Hardware Engineering, Software Engineering, Systems Engineering, or related work experience.
Preferred Qualifications:

• 3+ years of industry experience in machine learning, deep learning, or AI infrastructure
• Strong proficiency in Python, with hands-on experience in PyTorch, ONNX and/or TensorFlow
• Solid understanding of neural network architectures - CNNs, Transformers, LLMs, diffusion models, multimodal models
• Experience with model quantization techniques - PTQ, QAT, weight-only quantization, mixed-precision, sub-4-bit methods
• Hands-on experience quantizing LLMs (GPT, LLaMA, Mistral, Falcon, or similar families) for inference optimization
• Familiarity with AIMET, GPTQ, AWQ, SmoothQuant, or similar quantization frameworks is a strong plus
• Experience working with ONNX, TFLite/LiteRT, or other model interchange formats
• Understanding of hardware constraints: memory bandwidth, compute precision (INT4/INT8/FP16/BF16), and NPU/DSP execution
• Experience collaborating across teams or BUs to drive technical alignment and model delivery
• Proficiency with git and software development best practices
• Strong written and verbal communication skills - ability to write clean APIs, documentation, and engage directly with external developers
• Experience with C++ for performance-critical components is a bonus
• Familiarity with ARM processors and mobile SoC architecture (Snapdragon) is a plus
• Experience with automated evaluation pipelines and model benchmarking at scale is a plus

Level of Responsibility

• Works independently with minimal supervision
• Provides technical guidance and mentorship to other team members
• Decision-making is significant and affects work beyond the immediate team
• Requires strong communication skills to convey complex quantization concepts to varied audiences - from hardware engineers and BU partners to external researchers and application developers
• Has meaningful influence on the AIMET product roadmap, AI Hub model catalog, and cross-BU quantization strategy
• Tasks are open-ended; planning, prioritization, and problem-solving are core to the role
