Job description

About Quadric

Quadric has created an innovative general purpose neural processing unit (GPNPU) architecture. Quadric's co-optimized software and hardware is targeted to run neural network (NN) inference workloads in a wide variety of edge and endpoint devices, ranging from battery operated smart-sensor systems to high-performance automotive or autonomous vehicle systems. Unlike other NPUs or neural network accelerators in the industry today that can only accelerate a portion of a machine learning graph, the Quadric GPNPU executes both NN graph code and conventional C++ DSP and control code.

Role

AI Kernel Engineer. The AI Kernel Engineer in Quadric plays the key role to enable a large number of AI kernels/operators to run efficiently on the Quadric platform.

Key responsibilities:

• Develop AI/LLM kernels/operators on Quadric platform for efficient inference
• Optimize the kernel performance for different hardware configurations and workloads
• Profile and analyze kernel performance in terms of compute, data and parallelism; identify micro-architecture and software bottlenecks and provide optimization solutions
• Optimize kernel C/C++ codes, maximize hardware utilization
• Collaborate across related areas of the AI inference stack to support team and business priorities
• Make improvement to Quadric toolchain, compiler and runtime
• Provide technical support and documents to customers and developer community

Our preference is for a candidate located in the California Bay Area who can regularly collaborate from our Burlingame office. This role follows a hybrid schedule with at least two in-office days per week expected, but actual schedule may adjust depending on team and business need.

Requirements

• Bachelor's or Master's in Computer Science and/or Electric Engineering
• 5+ years of experience in AI kernel development and optimization
• Experience with model and kernel inference performance profiling
• Experience with at least one of the following compute development: CUDA, DSP, NEON, Triton-lang
• Proficiency in C/C++ and Python, experience with assembly language a plus
• Demonstrate good capability in problem solving, debug and communication

Benefits

• Competitive salary and meaningful equity
• Medical, dental, and vision plan options starting on day one
• 401(k) retirement plan
• Flexible paid time off (unlimited, non-accrual) to support work-life balance
• When working in-office, enjoy company-provided lunches and a stocked kitchen
• Convenient office location within walking distance of the Caltrain station
• Support for commuting, including monthly parking or Caltrain passes
• Downtown Burlingame office location, close to shops, cafes, and local amenities
• A politics-free, highly collaborative environment where talented people can do their best work and make an immediate impact
• The opportunity to build long-term career relationships in a company that values strong personal connections alongside professional excellence
