Principal Performance Engineer Lead

Job Description

Join the Akamai Inference Cloud Team! The Akamai Inference Cloud team is part of Akamai's Cloud Technology Group. We design and operate AI platforms that enable customers to run models with unmatched performance, compliance, and economics. The Model Intelligence & Lifecycle team owns the end-to-end model lifecycle from validation and security scanning through quantization, optimization, and monitoring, ensuring every model meets rigorous standards for quality, safety, and performance.

As an ML Performance Engineer Principal Lead, you will be responsible for:

• Applying and evaluating quantization, distillation, and pruning techniques to optimize model performance while preserving accuracy
• Designing hardware-aware model placement and scheduling strategies to match models with optimal compute resources
• Implementing and tuning speculative decoding, KV‑cache optimization, and batching strategies to improve inference throughput and latency
• Building benchmarking and profiling pipelines to measure model‑layer performance across architectures, hardware, and serving configurations
• Mentoring and guiding engineers on the team through code reviews, design discussions, and technical problem‑solving
• Collaborating with hardware performance engineers to identify and resolve end-to-end performance bottlenecks across the inference stack

To be successful in this role you will:

• Have 12+ years of relevant experience with a Bachelor’s or Master’s degree in Computer Science, Machine Learning, or a related field
• Possess hands‑on experience optimizing LLM inference performance (quantization, speculative decoding, model compression, etc.)
• Have a solid understanding of transformer architectures and how design choices impact latency, throughput, and accuracy
• Be experienced with inference serving frameworks such as vLLM, Tensor
  
  RT‑LLM, Triton, or similar systems
• Be proficient in Python and C++ with experience profiling and optimizing compute-intensive workloads
• Have familiarity with hardware‑aware optimization, including GPU/accelerator scheduling and memory management trade‑offs
