At Mem, we're working to empower people with the right information at the right time. The amount of digital data that we consume and produce on a daily basis has grown exponentially, but the way we access, search, and discover that information hasn’t kept up. We're seeking an AI Backend Engineer who can improve search quality and knowledge discovery in Mem. If you are someone who is creative and attentive to detail with a passion for knowledge retrieval and discovery, we're eager to meet you.

As an AI Backend Engineer, you will

  • Be responsible for search and discovery at Mem: the information retrieval systems that power our core Chat, Search, and realtime recommendation systems.
  • Experiment with and integrate state-of-the-art techniques in both LLM-augmented indexing and retrieval.
  • Establish and oversee methods for monitoring and managing result quality over time.
  • Invent new strategies for supporting dynamic browse experiences, enabling users to more easily discover knowledge.

You may be a good fit if you

  • Have prior experience in complex backend engineering environments. Prior founder or startup experience is a plus.
  • Are open-minded to using state-of-the-art tools. Classical search experience is not a must.
  • Expertise in Elasticsearch or machine learning is a plus, but not a requirement.
  • Are well-versed in systems thinking.
  • Have a meticulous eye for detail.
  • Enjoy working collaboratively.
  • Have strong written and verbal communication skills.
  • Are a self-starter with the ability to work independently and solve complex problems.
