Job Description

Qualcomm Cloud is seeking a Software Architect / Software Engineer with deep expertise in Linux user-space systems and AI frameworks to define and lead software architecture for next-generation inference platforms built on Qualcomm Cloud AI accelerators (AI 100 and successors).

This role combines technical leadership, architecture ownership, hands-on development, enabling scalable, high-performance APIs and runtime capabilities for ML frameworks such as PyTorch.

The ideal candidate will operate across software layers—from framework integration and runtime APIs to system-level performance optimization—while mentoring engineers and driving architectural direction across teams.

Key Responsibilities

Architecture & Technical Leadership

• Define and own the end-to-end architecture for user-space APIs and runtime layers enabling ML workloads on Qualcomm AI accelerators.

• Drive design of scalable, performant, and developer-friendly APIs for frameworks such as PyTorch.

• Establish design patterns, best practices, and technical standards across the software stack.

• Review and approve designs; provide technical guidance to Staff and Senior engineers.

Software Development & System Integration

• Lead hands-on development in C/C++ and Python for custom API layers and runtime components.

• Architect and implement multi-threaded, high-performance user-space systems.

• Drive integration across frameworks, runtime, drivers, and hardware acceleration layers.

• Optimize system performance including latency, throughput, and memory utilization.

Cross-Functional & Platform Leadership

• Collaborate with hardware, firmware, compiler, and framework teams to ensure cohesive system design.

• Influence product and platform direction through architecture decisions and performance insights.

• Act as a technical point of contact for complex system issues and customer escalations.

Mentorship & Engineering Excellence

• Mentor engineers across levels; elevate team capabilities through design reviews and technical coaching.

• Drive innovation in architecture and system design, evangelizing new approaches across the organization.
  

Required Skills and Experience

• 1 2 + years of experience in software engineering with strong emphasis on system architecture and design.

• Deep expertise in Linux user-space development and API design.

• Strong proficiency in C/C++ (1 2 + years) and Python.

• Experience designing multi-threaded and high-performance systems.

• Solid understanding of SoC architecture (CPU, memory hierarchy, interconnects, IO subsystems).

• Experience with source control and configuration management systems.

• Proven ability to lead architecture across teams and influence technical direction.

• Strong communication skills and ability to drive alignment across cross-functional stakeholders.
  

Preferred / Desirable Skills

• Familiarity with CUDA, NCCL, or equivalent accelerator programming models.

• Experience with IREE or ML compiler/runtime stacks.

• Understanding of PyTorch 2.0 (PT2) architecture and execution model.

• Knowledge of high-speed interfaces such as PCIe and RoCE .

• Experience with large-scale or heterogeneous compute systems.
