Electric Engineer at Space Start-Up*No Japanese Required

Space/Satellite Electrical and electronic

About the company
This company aims to create pioneering technology that is indispensable in our every day lives. Working primarily in the space industry, this company specializes in creating satellite technology that drastically makes one of the most traditionally expensive products - satellites - cost-effective and accessible on a commercial scale.

The two main services they provide is split between government and corporate clients.
On the government level, this company is working with JAXA in an exclusive partnership to build and launch 50 satellites into space by 2020. Using the combined satellite data, they aim to have total coverage of the earth’s total surface area. The rich macro data collected will thereafter be used to help sustain entire industries and geographies such as agriculture.

On a commercial level, the company will also be creating customised satellites for companies based on their specific business needs. This company is providing this service at a highly competitive rate amongst other providers because of their cost-reducing structure.

By developing and utilizing innovative technology in one of the hardest sectors to break into (i.e., the space industry) they have built a reputation for being a game-changing company in the sector both in Japan and globally. With applications in agriculture, forestry, infrastructure monitoring to say a few, the amount of data this company has developed has amassed information that can be used across sectors to manage and monitor activities for the better.
