About Quora: 

Quora’s mission is to grow and share the world’s knowledge. To do so, we have two knowledge-sharing products:

  • Quora: a global knowledge-sharing platform with over 400M monthly unique visitors, bringing people together to share insights on various topics and providing a unique platform to learn and connect with others.

  • Poe: a platform that lets people ask questions, get instant answers, and have back-and-forth dialogue with various AI language models (bots). As AI capabilities rapidly advance, Poe provides a single platform to instantly integrate and utilize these new models.

Behind these products are passionate, collaborative, and high-performing global teams. We have a culture rooted in transparency, idea-sharing, and experimentation that allows us to celebrate success and grow together through meaningful work. Join us on this journey to create a positive impact and make a significant change in the world.

About the Team and Role:

Our small Natural Language Processing team works on providing key NLP competence to improve Quora users’ experience. We build end-to-end industry-scale NLP systems for moderation (e.g. spam detection) and content-based recommendation (e.g. topic tagging and modeling content relevance). The team directly supports moderation and growth-related initiatives at Quora. As a remote-first company, our engineers have a high degree of flexibility and autonomy.

We are looking for an experienced Senior Machine Learning Engineer to join our growing NLP engineering team. You will have a unique opportunity to have a high impact by advancing our NLP systems, as well as uncovering new opportunities to apply large language models to the Quora product. You will also play a key role in developing tools and abstractions that our other developers will build on top of.


  • Improve our existing machine learning systems using your core coding skills and ML knowledge

  • Identify new opportunities to apply large language models to different parts of the Quora product

  • Perform experiments and comparative analysis to evaluate the effectiveness of different model architectures and fine-tune hyperparameters for optimal performance

  • Take end-to-end ownership of machine learning systems - from data pipelines, feature engineering, candidate extraction, model training, as well as integration into our production systems

  • Continuously research and stay up-to-date with the latest developments in NLP and large language models, utilizing innovative techniques and methodologies to enhance our models

  • Collaborate with the manager to lead the effort to transform our NLP systems to a new era of large language models

Minimum Requirements:

  • Ability to be available for meetings and impromptu communication during Quora's “coordination hours" (Mon-Fri: 9am-3pm Pacific Time)

  • 6+ years of professional software development experience in machine learning, ideally in an NLP team and/or as tech lead

  • BS, MS or PhD in Computer Science, Mathematics, or a related field with a focus on machine learning and NLP

  • Previous experience building end-to-end machine learning systems

  • Strong innovator who understands the nuances of large language models and has hands-on experience working with large language models like GPT, LLAMA, BERT, or Transformer-based architectures

  • Proficient knowledge of NLP techniques, including tokenization, language modelling, and embeddings

  • Experience with distributed training and optimization techniques for large-scale machine learning models


Preferred Requirements:

  • Excellent communication skills and the ability to collaborate effectively in a cross-functional team.

  • 2+ years of experience writing Python or C++ code

  • Experience with leading large-scale multi-engineer projects
