-

Partner with the Machine Learning team to define roadmaps. Balance user-facing improvements with investments in infrastructure, reliability, and experimentation.

-

Work with Data Science to co-own experimentation processes, tools, and best practices.

-

Expertise in Go, Java/JVM, or a similar backend language; Postgres, and AWS/GCP, and Kubernetes.

What Sets You Apart -

Experience with social networks or two-sided marketplaces in a subscription setting: you understand reciprocal interest, exposure, liquidity, and how great recommendations create long-term retentive value.

-

Familiarity with how machine learning and AI fit into modern recommender systems.

-

Experience with retrieval infrastructure such as Elasticsearch/OpenSearch, vector search, or feature stores.
