Performance Test Engineer Jobs in Massachusetts

Job Description

Do you want to push the boundaries of AI inference speed and accuracy at global scale?

Are you passionate about optimizing how models perform in production serving environments?

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. We ensure every model meets rigorous standards for quality, safety, and performance.

Partner with the best

As an ML Performance Engineer, you will optimize inference performance across the Akamai Inference Cloud. Your focus will be at the intersection of speed and accuracy applying techniques like quantization, speculative decoding, and hardware-aware scheduling to maximize throughput and minimize latency. You will collaborate closely with hardware performance engineers to deliver end-to-end optimization.

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

Do What You Love

To be successful in this role you will:

• 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
• Possess experience with inference serving frameworks such as vLLM, TensorRT-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
