Join the Qualcomm AI Hub team and help developers integrate machine learning into their products and experiences: https://aihub.qualcomm.com/.

Inthisroleyou willdevelop tools tohelp developersoptimizeand deploy machine learning models on edge and mobile hardware. AIMETis Qualcomm'sopen-source library forstate-of-the-artmodel quantization, and compression techniques. You will develop and supportcutting-edgemodel optimization workflows — pushing the boundary ofwhat'spossible 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 areseekinga talented and motivated Staff Software Engineer withexpertiseintheoptimizingand deployingML models– especially for edge devices.

• Design, develop, and maintain quantization algorithms and compression pipelines within the AIMET framework (PTQ, QAT, mixed-precision, AdaScaleetc.)

• 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 —PyTorchand 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

• 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.
• 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.
• PhD in Computer Science, Engineering, Information Systems, or related field and 2+ years of Hardware Engineering, Software Engineering, Systems Engineering, or related work experience.

• 3+ years of industry experience in machine learning, deep learning, or AI infrastructure

• Strongproficiencyin Python, with hands-on experience inPyTorch, 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

• Proficiencywith 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

• 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

• Requiresstrong communicationskills 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
