## Role details

## Overview

Meta is undertaking a transformative change to its business and technology. Our Machine Learning teams are at the forefront of this evolution, tackling crucial projects and initiatives that have never been done before. This is an opportunity to advance how people connect around the world. To meet scale demands, we approach machine learning as a system engineering challenge, pushing the boundaries of scalable computing and integrating multiple complex platforms to build models that leverage trillions of actions. Our research and production implementations incorporate innovations from Meta’s AI, Distributed Computing, and Databases research, and run on the same hardware and network specifications open sourced through the Open Compute project.

As a PhD intern at Meta, you will help build machine learning systems and models behind Meta’s products, create web applications that reach millions of people, build high-volume servers, and contribute to a team that helps connect people globally. PhD interns are matched to a relevant team based on experience and interests. Internships are twelve (12) to twenty-four (24) weeks long with various start dates throughout the year.

## Responsibilities

  
- Develop highly scalable classifiers and tools leveraging machine learning, regression, and rules-based models.
  
- Gather, synthesize, and prioritize requirements and create effective feature roadmaps.
  
- Code deliverables in collaboration with the engineering team.
  
- Adapt standard machine learning methods to exploit modern parallel environments (e.g., distributed clusters, multicore SMP, and GPUs).

## Qualifications

  
- Currently pursuing or possessing a PhD in Computer Science, Computer Vision, Machine Learning, or a related field.
  
- Research and/or work experience in a relevant field, such as machine learning, deep learning, reinforcement learning, NLP, recommendation systems, pattern recognition, signal processing, data mining, artificial intelligence, or computer vision.
  
- Experience in systems software or algorithms.
  
- Experience coding in Python, C/C++.
  
- Must obtain work authorization in the country of employment at the time of hire and maintain ongoing authorization during employment.
  
- Intent to return to a degree program after completing the internship/co-op.
  
- Demonstrated software engineering experience via an internship, work experience, coding competitions, or open-source contributions.
  
- Proven track record of significant results as demonstrated by grants, fellowships, patents, or first-authored publications at leading conferences or journals.
  
- Demonstrated creativity and quick problem-solving abilities.
  
- Experience with large-scale data analysis and processing.
