Tiki Search team owns the platform that powers Search - a critical customer-focused feature of Tiki.vn. Whenever you are looking for a specific product on Tiki, it is our technology that delivers you outstanding search results.

Challenges we are facing:

• How to serve search responses in high performance and fault-tolerant manner while supporting 10k product updates per second in real-time
• How to extract as much valuable information as possible from non-structured product data and product reviews written in natural language
• How to turn that information into ranking features that help to increase search relevancy for our customers
• How to process customer queries and extract the right features to help the ranking system to produce better results
• How to integrate “rich” results like recommended filters, sellers or custom mini-apps into search in a way that is helpful for customers
• How to make sure that the improvements are "truly" there with the right A/B testing process

With all those challenges we apply cutting-edge engineering, machine learning, and statistical methods, so working with us is a great opportunity to apply your knowledge while also learning something new at the same time.
