Build production machine learning systems at Reddit using Python, model serving, and large-scale data pipelines. Work spans Consumer and Ads organizations across the platform.

As a Machine Learning Engineer, you will develop systems supporting recommendations, search, ranking, advertising, and user understanding. You will own machine learning lifecycles from problem definition and feature engineering through deployment and monitoring. The work includes deep learning, transformers, graph methods, and LLM evaluation or alignment.

Key Responsibilities

Design and deploy production machine learning models at scale

Build reliable pipelines with observability and automated retraining

Improve latency, throughput, and model quality metrics

Partner with Product, Data Science, Infrastructure, and Engineering





Contribute to technical strategy and long-term machine learning roadmaps

Requirements

Three to five-plus years operating production machine learning systems

Solid Python, Java, Go, or similar programming skills

Knowledge of statistical learning and deep learning architectures

Experience with PyTorch or TensorFlow frameworks

Experience designing scalable pipelines and model-serving infrastructure

Apply machine learning, software engineering, and production systems expertise to Reddit’s discovery, relevance, and advertising experiences.
