About the Job

· give more insight to our marketing and operations teams via more historical data and improved analytics

· unify inventory management responsibilities currently spread across multiple systems and teams



· Solid understanding of designing, developing and supporting large scale, cloud based distributed systems

· Good understanding of event-driven systems

· Strong operational excellence and testing skills

· Comfortable taking part in the (daytime only) on-call rotation.

Nice to Have:

· Fluent in a few programming languages, functional, dynamic and static

· Solid understanding of how to use data structures to solve problems optimally

· In depth knowledge of runtime and space complexity of data structures and the proposed solution

· Exposure to event based and asynchronous processing
