4000_Software-Defined Radio Development Engineerの求人

【Company Overview】 ArkEdge Space Inc. is a space startup founded in 2018, specializing in the design, manufacturing, and operation of small satellites. We focus on the development of ultra-small satellites, particularly 6U and 50kg-class satellites, as well as the creation of satellite constellations—networks of multiple satellites. In addition, we offer a wide range of services, including the provision of related components and software, as well as the operation of ground stations for satellite control. With the mission of "Creating a safer and more prosperous future through satellites," we strive to make space development and utilization accessible to everyone. We are actively building ultra-small satellite constellations for various missions, such as Earth observation, maritime satellite communication (satellite VDES), optical communication, and low-orbit satellite positioning. Furthermore, we are engaged in cutting-edge space missions, including satellite infrastructure development for lunar activities and deep-space exploration. By pioneering these initiatives, we contribute to the creation of a new space industry ecosystem. 【Selection Process】 Document Screening ＞ First Interview ＞ Second Interview ＞ Final Interview 【Job Overview】 Analyze signal formats for low Earth orbit (LEO) and lunar navigation satellites, and develop interface and signal definition documents.
