LLMInference &EvalsEngineer

About The Role

Join the inference model team dedicated to bring up the state-of-the-art models, numerically validating and accelerating new model ideas on wafer-scale hardware. You will prototype architectural tweaks, build performance-eval pipelines, and turn hard numbers into changes that land in production.

• Prototype and benchmark cutting-edge ideas: new attentions, MoE, speculative decoding, and many more innovations as they emerge.
• Develop agent-driven automation that designs experiments, schedules runs, triages regressions, and drafts pull-requests.
• Work closely with compiler, runtime, and silicon teams: unique opportunity to experience the full stack of software / hardware innovation.
• Keep pace with the latest open- and closed-source models; run them first on wafer scale to expose new optimization opportunities.

• 3 + years building high-performance ML or systems software.
• Solid grounding in Transformer math-attention scaling, KV-cache, quantisation, or clear evidence you learn this material rapidly.
• Comfort navigating the full AI toolchain:
  Python modeling code, compiler IRs, performance profiling, etc.
• Strong debugging skills across performance, numerical accuracy, and runtime integration.
• Prior experience in modeling, compilers or crafting benchmarks or performance studies; not just black-box QA tests.
• Strong passion to leverage AI agents or workflow orchestration tools to boost personal productivity.

• Hands-on with flash-attention, Triton kernels, linear-attention, or sparsity research.
• Performance-tuning experience on custom silicon, GPUs, or FPGAs.
• Proficiency in C / C++ programming and experience with low-level optimization.
• Proven experience in compiler development, particularly with LLVM and / or MLIR.
• Publications, repos, or blog posts dissecting model speed-ups.
• Contributions to open-source agent frameworks.
