Machine Learning Engineer Reddit

Build production machine learning systems at Reddit using Python, PyTorch, and TensorFlow in a remote contract role across Canada.

As a Machine Learning Engineer, you will develop end-to-end systems for Reddit’s Consumer and Ads organizations. Apply algorithms, data pipelines, model serving, and software engineering to recommendations, search, ranking, advertising, and user understanding. The work spans research, modeling, deployment, and monitoring.

Key Responsibilities:

• Design and deploy production-grade machine learning models at scale
• Own feature engineering, training, evaluation, deployment, and monitoring
• Build reliable pipelines with observability and automated retraining
• Improve latency, throughput, and model quality metrics
• Apply deep learning, graph, transformer, and LLM techniques

Requirements:

• Three to five plus years operating production machine learning systems
• Strong Python, Java, Go, or similar programming skills
• Knowledge of statistical learning and deep learning architectures
• Hands-on PyTorch or TensorFlow experience
• Experience with scalable pipelines and model serving infrastructure

Bring production machine learning, scalable systems, and applied AI expertise to Reddit’s recommendations, search, and advertising platforms.
