Job summary

Discord is seeking a Senior Machine Learning Engineer to join the Engagement ML team in the Growth organization. You will design and ship end-to-end ML solutions that help new users find servers, people, and content, turning a first session into a lasting connection with the product.

Responsibilities include building retrieval/ranking pipelines, embeddings-based retrieval, and production ML models that improve new-user retention.

Qualifications

5+ years of experience in Machine Learning, Data Science, or Applied Science with a track record shipping recommendation or personalization systems end to end.
Hands-on experience building modern recommendation systems: retrieval and ranking pipelines, embedding-based retrieval, and deep learning models such as transformers.

Responsibilities

Design, build, and scale recommendation systems that connect new users to communities and content from candidate generation to online serving.
Solve cold-start personalization for users with little history, turning signals into recommendations.
Build and deploy ML models that lift new-user retention, combining embeddings and production-grade systems.
Collaborate cross-functionally to shape the Onboarding roadmap and balance fast experiments with long-term scalability.
