About the role
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. As a remote-first company, our engineers have a high degree of flexibility and autonomy. Everyone on the engineering team has a significant impact on our product and our company. We are looking for an experienced machine learning engineer to join our distribution team, working on recommendation systems such as feed, notifications, and Quora's famous digest emails. 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 ranking modeling expert, you will own and advance the second-phase ranking model behind feed and digest, one of the highest-leverage surfaces at Quora, by applying the latest machine learning techniques. You will also play a key role in developing methodologies that our other developers will build on top of.
What you would do
- Improve our existing machine learning ranking models using your core coding skills and ML knowledge
- 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
- 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 efficiently
What they are looking for
- Availability for meetings and impromptu communication during Quora's “coordination hours https://quora.com/coordination_hours" (Mon-Fri: 9am-3pm Pacific Time)
- 3+ years of professional experience working on recommendation or ranking models
- Good understanding of mathematical foundations of machine learning algorithms
- Previous experience building end-to-end machine learning systems
- Good communication and interpersonal skills
- BS, MS, or PhD in Computer Science, Engineering, or a related technical field
