Machine Learning Engineer

What you can expect

Zoom is looking for a Machine Learning Engineer to join our Agentic Retrieval team. You will design and build the core retrieval and reasoning systems that power Zoom’s AI Companion — enabling AI agents to search, reason over, and act on enterprise knowledge to deliver high- quality, trustworthy, and actionable answers at scale.

About the Team

The Agentic Retrieval team sits within Zoom’s GenAI Engineering organization and is responsible for building a multi-tenant, permission-aware retrieval platform. We operate at the intersection of distributed systems, machine learning, and large language models — powering search and answer generation across meetings, chat, docs, and third-party enterprise applications through a layered API architecture (keyword search, natural language search, and agentic RAG-based answer generation).

Responsibilities:

• Designing and implementing scalable retrieval systems including vector search, hybrid search (keyword + embedding + reranking), and structured query planning.
• Designing and optimize Retrieval-Augmented Generation (RAG) pipelines for multi-step, tool-using AI agents.
• Developing ranking, relevance modeling, and evaluation frameworks to improve search quality and answer grounding.
• Building indexing pipelines that transform heterogeneous enterprise data into unified, retrieval-ready representation.
• Building entity extraction and NLP pipelines that support agentic reasoning over enterprise content.
• Partnering with product, infrastructure, and applied research teams to ship production- grade AI capabilities.

What we’re looking for

• Master’s degree or higher in Computer Science, Artificial Intelligence, Machine Learning, Distributed Systems, or a related field.
• 5+ years of experience in machine learning, search infrastructure, information retrieval, or distributed systems
• Strong hands-on experience building and operating large-scale search or data platforms in production environments.
• Have experience building or integrating RAG systems and LLM-based applications in production.
• Possess proficiency in one or more of: Python, Go, Java, C#, or C++.
• Solid understanding of information retrieval fundamentals (inverted index, ranking,
  embeddings, hybrid retrieval).
• Strong system design skills with the ability to reason about scale, reliability, latency, and cost trade-off.

Salary Range or On Target Earnings:

In addition to the base salary and/or OTE listed Zoom has a Total Direct Compensation philosophy that takes into consideration; base salary, bonus and equity value.

Note: Starting pay will be based on a number of factors and commensurate with qualifications & experience.

We also have a location based compensation structure;  there may be a different range for candidates in this and other locations

At Zoom, we offer a window of at least 5 days for you to apply because we believe in giving you every opportunity. Below is the potential closing date, just in case you want to mark it on your calendar. We look forward to receiving your application!
