This expectation is subject to local law and may vary by jurisdiction.

Responsibilities:

Serves as the technological core of Microsoft’s rapidly expanding digital advertising business.

Focus on accelerating Microsoft’s large-scale deep learning inference for Ads, Shopping, Copilot, and other surfaces, including both offline and online applications that support OpenAI LLM models and next-generation LLMs/SLMs.

Play a pivotal role in bridging state-of-the-art GPU and deep learning technologies with critical business applications.

Qualifications:

Required Qualifications:

Bachelor’s Degree in Computer Science or related technical field AND 8+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.

Ability to meet Microsoft, customer and/or government security screening requirements are required for this role.

These requirements include but are not limited to the following specialized security screenings:

Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter.

Preferred Qualifications:

Master’s Degree in Computer Science or related technical field AND 12+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR Bachelor’s Degree in Computer Science or related technical field AND 15+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.

Solid experience in GPU inference optimization (CUDA, TensorRT, Triton, or custom GPU kernels).

Proficiency in profiling tools (Nsight, TensorBoard, PyTorch profiler) and ability to identify CPU/GPU bottlenecks.

Deep understanding of LLM/SLM architectures (attention, embeddings, MoE, decoders).

Experience optimizing latency-critical online services.

Experience with model compression (quantization, distillation, SVD, low-rank methods).

Experience in building high-throughput inference serving stacks (continuous batching, KV-cache optimizations, routing).

Familiarity with Microsoft’s DLIS, Talon routing, Triton/TensorRT-LLM stack, and Azure/H100/A100 GPU environments.

Publications, competition wins, or real-world deployments related to model efficiency.
