General Summary:

About the Role

Qualcomm AI Hub is the platform for on-device AI - enabling developers to easily integrate,optimize, and deploy ML models on Qualcomm devices. Qualcomm AI Hub Workbench lets developers compile trainedPyTorchor ONNX models into deployable artifacts targeting a variety of runtimes -LiteRT,ONNXRuntime, or Qualcomm AI Engine Direct SDK (QAIRT) - and profile andvalidatethem on real Qualcomm devices hosted in the cloud.

Join the Qualcomm AI Hub Compiler team and own the infrastructure that powers these model compilations. You will work across the full compilation pipeline - from model ingestion and graph optimization to backend dispatch across CPU, GPU, and NPU - ensuring models compile correctly, execute efficiently, and scale across a growing catalog of on-device use cases spanning vision, audio, speech, and multi-modal models.

What You'll Do

Compiler Pipeline & Infrastructure

• Design, develop, andmaintainthe end-to-end compilation pipeline powering Qualcomm AI Hub Workbench, fromPyTorchand ONNX model ingestion through graph optimization to deployable artifacts targetingLiteRT,ONNXRuntime, or QAIRT on Snapdragon SoCs

• Build and maintain ONNX-based compilation paths using ONNX IR: graph transformation passes, op validation, andopsetcompatibility handling

• Build and maintainPyTorchcompilation paths consumingtorch.exportoutput, including dynamic shapes, custom ops, andATenIR decomposition

• Contribute toONNXRuntimeQNN execution provider: graph optimizations, graph partitioning, and op validation andlowerings

• Collaborate with QAIRT and QNN teams to ensure correct and efficient model execution across CPU, GPU, and NPU backends

• Build tooling to analyze, profile, and debug compilation failures, accuracy regressions, and performance degradations; develop clear, actionable developer-facing diagnostics

Model Catalog, Automation & Collaboration

• Own compilation and validation of models published on Qualcomm AI Hub, ensuring correct conversion and verified performance across supported runtime targets

• Build andmaintainautomated compilation pipelines and CI/CD evaluation harnesses to scale model onboarding as the Qualcomm AI Hub model catalog grows

• Partner with internal Business Units to onboard models through Qualcomm AI Hub compilation workflows, translating deployment constraints (target SoC, latency budgets, memory limits) into concrete compilation strategies

• Author technical documentation, tutorials, and example notebooks for the Qualcomm AI Hub developer community

Minimum Qualifications:

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 ML infrastructure, compiler engineering, or AI framework development

• Proficient in Python and C++

• Solid understanding of ML compiler concepts (graph IRs, operator fusion, shape inference, lowering passes, backend partitioning) and hands-on experience with one or more compiler stacks such as MLIR, ONNX, or TVM

• Experience withPyTorchmodel export (torch.export,torch.compile, FX,ATenIR) and on-device deployment frameworks such asLiteRT,ExecuTorch, orONNXRuntime

• Familiarity with SoC-level constraints (memory bandwidth, compute precision, NPU/DSP execution) and hardware-specific runtimes such as QAIRT/QNN is a plus

• Experience building automated CI/CD pipelines for model compilation and validation at scale

• Strong written and verbal communication skills;proficiencywith git and software engineering best practices

Level of Responsibility

• Works independently on open-ended compiler and infrastructure challenges

• Provides technical guidance and mentorship to team members

• Decision-making has broad impact - affecting compilation correctness, runtime performance, and the developer experience across Qualcomm AI Hub

• Communicates complex compiler and runtime concepts to varied audiences: SoC engineers, BU partners, and external ML developers

• Has meaningful influence on the Qualcomm AI Hub compiler roadmap, model catalog strategy, and cross-team runtime integration priorities
