We are looking for Blockchain Engineers to help us design practical, efficient and large-scale performant blockchain systems. Are you reaching your potential in your current field? or do you have an opportunity to show your knowledge and skills enough? A new ecosystem for athletes and audience "JUNGLE" imagines has a lot of challenges and makes you crazy about blockchain more.

"JUNGLE" is not a conventional betting institution, which means we do people business and provide betting.
We are all motivated by the mission "Betting Saves The Earth" and believe our services dramatically change the definition of betting and bring a new customer experience. The mission is not a pie in the sky. Our great culture which includes Mandala (norms) and Altruism always drive us to change the world with betting.
