Member of Technical Staff, Hardware, Kernel Engineer (Custom Silicon)

Location: Austin, Texas or Palo Alto, California

Annual salary: $200,000–$420,000 USD

Company

hirify.global is developing personal AI through personal hardware for local inference, custom training infrastructure, next-generation user interfaces, and deep learning research.

What you will do

• Design C++ code-generation frameworks and metaprogramming toolchains that emit optimized assembly for custom hardware.
• Implement and optimize deep learning primitives including GEMM/MatMul, attention, convolutions, and element-wise layers.
• Tune instruction scheduling, register allocation, and software pipelining to maximize hardware utilization and reduce execution latency.
• Develop tiling, double-buffering, and data-movement strategies for efficient SRAM use and reduced memory bandwidth bottlenecks.
• Collaborate with compiler, RTL, architecture, and deep learning teams on hardware/software co-design.
• Benchmark and validate generated assembly using hardware simulators, silicon, and performance counters.

Requirements

• Bachelor’s degree in Computer Engineering, Computer Science, Electrical Engineering, or a related field, plus 5+ years of practical industry experience in low-level performance programming.
• Experience with hardware programming models such as CUDA, Triton, CUTLASS, or custom accelerator assembly, with a record of shipping optimized kernels.
• Advanced knowledge of computer architecture, including vector units, execution pipelines, register files, caches, SRAM, HBM, and DRAM.
• Proficiency in modern C++ for scalable metaprogramming and code-generation frameworks.
• Strong mathematical foundation in linear algebra and deep learning primitives.
• Visa sponsorship is available; the role is based in the United States.

Nice to have

• Experience optimizing Tensor Cores, matrix multiply-accumulate units, or custom vector extensions.
• Advanced C++ template metaprogramming or automated generation of parameterized kernel variants.
• Experience with hardware profiling, execution tracing, performance counters, cache misses, pipeline stalls, and ALU bubbles.

Culture & Benefits

• Work alongside scientists, engineers, and builders from leading technology companies and AI labs.
• Health, dental, and vision benefits.
• Unlimited paid time off.
• Relocation support as needed.
