The Staff Machine Learning Systems Engineer role at Reddit is a remote position based in the United States, focused on leading the development of platforms for large-scale machine learning models. This opportunity suits experienced engineers with a deep understanding of ML infrastructure who want to empower teams across recommendations, feeds, ads, and growth.

Key Responsibilities

Spearhead the development of a platform dedicated to large-scale machine learning models.
Create end-to-end model lifecycle patterns, known as MLOps, to accelerate development speed for machine learning engineers across data preparation, experiment tracking, and model management.
Build and support a graph machine learning codebase and platform from zero to one, abstracting away common patterns to maximize model scalability and iteration.
Partner closely with machine learning engineers on performance tuning to enhance model training times, efficiency, and GPU training costs within distributed training environments.
Optimize batch data processing inside a data warehouse utilizing tools like Apache Spark, Apache Beam, and Ray Data.
Design and architect pipelines that construct and maintain massive graph data structures featuring billions of nodes and tens of billions of edges.

Requirements

Eight or more years of professional experience in machine learning infrastructure, encompassing model training and deployment.
Practical experience handling machine learning optimization, specifically memory and GPU profiling.
Extensive background utilizing cloud-based technologies for machine learning platforms, including Google Cloud Storage, GCP BigQuery, and infrastructure-as-code options like Terraform.
Direct experience administering and integrating MLOps tools for model serving, model registries, and experiment tracking such as Wandb or MLflow.
Strong proficiency in standard machine learning programming languages and frameworks, including Python, TensorFlow, and PyTorch.
Deep familiarity operating within distributed training frameworks like Kubernetes and Ray.
