About the Team

Sana is an AI lab building superintelligence for work. We believe organizations can accomplish their missions faster when humans can effortlessly access knowledge, automate repetitive work, and learn anything with the help of agentic AI. As part of Workday, we are committed to building AI that augments humans. If that’s a mission that excites you, you’re in the right place.

About the Role

You'll design hybrid retrieval pipelines, ranking algorithms, and search APIs that enable agents to reason and act on the right information. Strong expertise in search engines, vector databases, embedding models and ranking algorithms is essential for success in this role. Search is rapidly transforming in the age of agents and you'll be at the forefront.

  • Scale search infrastructure to billions of documents across multi-tenant environments

  • Design hybrid retrieval combining semantic vector search with traditional IR techniques

  • Build ranking systems that learn from user behavior to improve relevance

  • Optimize the full search stack—query understanding, indexing, and distributed retrieval

  • Establish observability frameworks to measure and improve search quality

  • Shape the future of knowledge discovery with product and design teams

About You

  • Experience with GCP/Kubernetes/Terraform

Other Qualifications

  • Search scales to enterprise volumes with sub-second latency and uptime

  • Retrieval applies proven IR techniques and cutting-edge agentic search

  • Balance hands-on implementation with system design and mentorship

  • Performance bottlenecks are solved proactively across the stack

  • Agents consistently find and use the right context to serve users



Our Approach to Flexible Work
 

With Flex Work, we’re combining the best of both worlds: in-person time and remote. Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in-office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote "home office" roles also have the opportunity to come together in our offices for important moments that matter.
