Design, develop, and operate a mission control system for rocket launches and combustion tests, building reliable, low-latency services across backend and frontend systems.
About this role
This role defines requirements and designs the architecture for a 5G NTN (non-terrestrial network) connecting terminals, satellites, ground stations, and customer networks. Responsibilities include technical discussions with partners, contract negotiations, technology selection, and vendor selection.
The product domain is direct-to-device (D2D) satellite communications. Interstellar Technologies aims to make it possible for terminals to connect directly to satellites without special dedicated equipment and to build communications infrastructure for areas outside the reach of terrestrial networks.
The company develops satellite-related technologies in-house and also works with external partners through open innovation. It has been selected for commissioned research by Japan’s Ministry of Internal Affairs and Communications and for the Japan Aerospace Exploration Agency’s Space Strategy Fund. In December 2025, it completed a ground principle experiment for an array antenna.
Interstellar Technologies also has its own rocket launch capability as part of an integrated rocket and satellite business. The company was founded in 2013 in Taiki, Hokkaido, and has developed the MOMO sounding rocket, which reached outer space as the first such achievement by a Japanese private company operating independently.
The stated work location is the company’s Tokyo Second Branch in Koto-ku, Tokyo. Indoor smoking is generally prohibited, with a smoking-only room available in a shared area on the same floor.
