Senior Software Engineer - Machine Learning Recommendation Systems


About Quora:

The vast majority of human knowledge is still not on the internet. Most of it is trapped in the form of experience in people's heads, or buried in books and papers that only experts can access. More than a billion people use the internet, yet only a tiny fraction contribute their knowledge to it. We want to democratize access to knowledge of all kinds — from politics to painting, cooking to coding, etymology to experiences — so if someone out there knows something, anyone else can learn it. Our mission is to share and grow the world's knowledge, and we're building a world-class team to help us achieve this mission.

About the Team:

Our small engineering team works on challenging problems every day. We have a culture that's rooted in constantly learning and improving, and our engineers are encouraged to think big and experiment with new ideas. Using continuous deployment, we quickly see our changes in the product and make fast iterations. Our engineers focus on creating polished products and writing high quality code by designing APIs and abstractions that are extensible and maintainable. As a remote first company, our engineers have a high degree of flexibility and autonomy. Everyone on the engineering team has a huge impact on our product and our company.

About the Role:

We are looking for an experienced Machine Learning engineer to join our growing engineering team, working on recommendation systems such as feed and A2A. At Quora, we use machine learning in almost every part of the product and recommendation systems play an important role in connecting users with content. As a recommendation systems expert, you will have a unique opportunity to have high impact by advancing our ranking systems as well as uncovering new opportunities to apply machine learning to the Quora product. You will also play a key role in developing tools and abstractions that our other developers would build on top of.


  • Improve our existing machine learning systems using your core coding skills and ML knowledge
  • Identify new opportunities to apply machine learning to different parts of the Quora product
  • Work with other machine learning engineers to implement algorithms and systems in an efficient way
  • Take end to end ownership of machine learning systems - data pipelines, candidate extraction, feature engineering, model training, as well as integration into our production systems

Minimum Qualifications:

  • Ability to be available for meetings and impromptu communication during Quora's "coordination hours" (Mon-Fri: 9am-3pm Pacific Time). Learn why here.
  • 3+ years of professional software development experience in machine learning
  • 1+ years of professional experience working on recommendation systems
  • Good understanding of mathematical foundations of machine learning algorithms
  • Previous experience building end to end machine learning systems
  • BS, MS or PhD in Computer Science, Engineering or a related technical field

Preferred Qualifications:

  • Strong communication and interpersonal skills
  • 5+ years of overall professional machine learning experience with 3+ years of professional recommendation systems experience.
  • 2+ years of experience writing Python or C++ code
  • Experience with leading large-scale multi-engineer projects
  • Flexible and positive team player with outstanding interpersonal skills
  • Passion for Quora's mission and goals
