Machine Learning Engineer (Contract) - Advanced Algorithmic and AI Capabilities

This is a long term contract and 100% remote.

Purpose:

An experienced Machine Learning Engineer (Contract) to build advanced algorithmic and AI capabilities across Personalization, Generative AI, Forecasting, and Decision Science. This role combines deep technical modeling expertise with infrastructure engineering to develop and operate end‑to‑end ML/AI systems at scale.

You’ll work closely with Data Science, Data Engineering, and Architecture teams—serving as both a solutions architect and a hands‑on engineer driving production‑ready AI systems.

Responsibilities:

• Design and optimize machine learning models including deep learning architectures, LLMs, and BERT-based classifiers
• Build distributed training workflows using PyTorch and similar frameworks
• Fine‑tune large language models and optimize inference performance (Neuron Compiler, ONNX, vLLM)
• Optimize models for GPU, TPU, and AWS Inferentia/Trainium
• Design AI services for both real‑time and batch processing use cases
• Lead development of ML infrastructure covering data ingestion, feature engineering, training, and serving
• Build scalable inference systems for real-time and batch predictions
• Deploy models across EC2, EKS, SageMaker, and specialized inference hardware
