2. You are great at identifying risks and opportunities, and have the depth that comes with willingness and capability to be hands-on. Do you still code? Do you love to code? Do you love to roll up your sleeves and debug things?

Responsibilities:

• You will help build a platform that supports large scale data, with multi-tenancy and near real-time analytics.

And that success needs the creative mindset to deal with ambiguities when you start, the courage to handle rejections and failure and rise up, and the persistence and humility to iterate and course correct.

1. We look for people who are initiative driven, and not interruption driven. The ones who challenge the status quo with humility and candor.
2. We believe startup managers and leaders are great individual contributors too, and that there is no place for context free leadership.
3. We believe that the curiosity and persistence to learn new skills and nuances, and to apply the smartness in different contexts matter more than just academic knowledge.
