• Design and implement graph transformations, graph lowering, and optimization techniques within AI runtime environments such as ONNX Runtime, ExecuTorch and Qualcomm AI Stack SDK.

• Apply knowledge of quantization and performance optimization to improve latency, throughput, memory usage, and power efficiency.

• Work at the forefront of Generative AI, understanding advanced algorithms such as attention mechanisms, Mixture-of-Experts (MoE), Low Rank Adapter (LoRA) and emerging inference optimization techniques (e.g., Speculative Decoding etc.).

• Collaborate with ML Research teams to prototype and productize new features and techniques into SDK solutions.

• Debug complex issues across models, runtime, OS, compiler, and hardware layers, working closely with QA and customer teams.

• Design, implement, and deliver new features and enhancements to the Qualcomm AI Stack SDK.

• Participate in design reviews and code reviews, ensuring software quality and maintainability.

• Mentor junior engineers helping them prioritize work, and drive execution across multiple initiatives.

Minimum Qualification (Must Have)

• Bachelor’s degree in computer science, computer engineering, or a related field and 6+ years (Staff) / 8+ years (Sr. Staff) of experience in software design, development, and delivery.

• OR

• Master’s degree/PhD in computer science, computer engineering, or a related field and 5+ years (Staff) / 7+ years (Sr. Staff) of experience in software design, development and delivery.

• 3+ years of hands-on experience in AI/ML software development, with a focus on inference or model optimization.

• Strong understanding of AI/ML fundamentals, including deep learning and inference pipelines.

• Deep understanding of transformer architectures, attention mechanisms, and performance tradeoffs.
