Job Overview

We are 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, and enables 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.

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

• 12+ 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++ (12+ 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.

Benefits

• Salary, stock and performance‑related bonus
• Maternity/Paternity Leave
• Employee stock purchase scheme
• Matching pension scheme
• Education assistance
• Relocation and immigration support (if needed)
• Life, medical, income and travel insurance
• Subsidised memberships for physical and mental well‑being
• Bicycle purchase scheme
• Employee‑run clubs, including running, football, chess, badminton and many more

Minimum Qualifications

• Bachelor’s degree in Engineering, Information Systems, Computer Science, or related field and 6+ years of Software Engineering or related work experience.
• Master’s degree in Engineering, Information Systems, Computer Science, or related field and 5+ years of Software Engineering or related work experience.
• PhD in Engineering, Information Systems, Computer Science, or related field and 4+ years of Software Engineering or related work experience.
• 3+ years of work experience with Programming Language such as C, C++, Java, Python, etc.
• References to a particular number of years experience are for indicative purposes only. Applications from candidates with equivalent experience will be considered, provided that the candidate can demonstrate an ability to fulfill the principal duties of the role and possess the required competencies.
