We are looking for exceptional Engineers, who take pride in creating simple solutions to apparently-complex problems. Our Engineering tasks typically involve at least one of the following:

  • Building a pipeline that processes up to billions of items; frequently employing ML models on these datasets

  • Creating services that provide Search or other Information Retrieval capabilities at low latency on datasets of hundreds of millions of items

  • Crafting sound API design and driving integration between our Data layers and Customer-facing applications and components

  • Designing and running A/B tests in Production experiences in order to vet and measure the impact of any new or improved functionality

What you will accomplish:
  • Design, deliver, and maintain significant features in data pipelines, ML processing, and / or service infrastructure

  • Take active part in knowledge sharing across the organization - both teaching and learning from others

What you will bring:
  • B.Sc. or M.Sc. in Computer Science or an equivalent professional experience

  • 7+ years of software design and development experience, tackling non-trivial problems in backend services and / or data pipelines

  • Full proficiency in Python; additional hands-on experience with Java is a plus!

  • Solid foundation in Computer Science with strong proficiencies in Data Structures, Algorithms, Object-Oriented Programming, and Software Design

  • Experience in designing and operating Big Data processing pipelines, such as: Hadoop, Spark, Hive

Preferred Qualifications as a plus:
  • Track record of impactful publications and/or patents in machine learning or related areas.

  • Contributions to open-source ML tools or frameworks.

  • Experience with modern large language models, graph-based ML, or knowledge graph construction.

  • Strong presence in scientific communities through talks, panels, or organizing roles.
