• Work at the forefront of GenAI by understanding advanced algorithms (e.g. attention mechanisms, MoEs) and numerics to identify new optimization opportunities.

• Performance analysis and optimization of LLM, VLM, and diffusion models for inference. Scale performance for throughput and latency constraints.

• Mapping the next generation AI workloads on top of current and future hardware designs.

• Work closely with customers to drive solutions by collaborating with internal compiler, firmware and platform teams.

• Analyze complex performance or stability issues to work towards final root cause of underlying problems.

• Create engineering solutions to deliver continuous insights into performance of AI workloads guiding the improvements over time.

• Design and implement high-level kernels, e.g. in Triton, with a focus on generating efficient, low-level code.

Candidates for this position will demonstrate the following:

• Hands-on experience in building and optimizing language models, notably in PyTorch, ONNX, preferably in production-grade environments.

• Deep understanding of transformer architectures, attention mechanisms and performance trade-offs.

• Experience in workload mapping strategies exhibiting sharding or various parallelisms.

• Strong Python programming skills.

• Proactive learning about the latest inference optimization techniques.

• Understanding of computer architecture, ML accelerators, in-memory processing and distributed systems.
