Design and specify satellite navigation payload systems, document requirements and interfaces, coordinate external contractors, manage development progress, and assess system risks and quality.
About this role
This position leads the requirements definition, design, evaluation, and feasibility assessment of optical communication terminals (LCTs) intended for installation on small satellites. The work covers optical communication between satellites, between satellites and HAPS, and between satellites and ground stations, as well as the feasibility of the overall optical communication system including optical ground stations.
Responsibilities include defining LCT specifications such as beam acquisition and tracking methods, modulation methods, communication speed, power consumption, and size and weight constraints. The role also handles LCT link design, feasibility evaluation, and performance simulations. It organizes requirements for acquisition and tracking, compensation, optical systems, and control systems, and develops the design and operational requirements for optical ground-station networks.
The position includes technical discussions with vendors and partners, preparation of evaluation plans, and interface design with the end-to-end architect and network-control teams. The broader product context is an NTN service that combines a communications satellite constellation using small satellites with terrestrial networks. The company is developing and commercializing an NTN and optical communications constellation business intended to connect land, sea, air, and space.
The named tools and technologies include Windows and Linux operating systems; GitHub for code management; GitHub Projects V2 and GitHub Issues for task management; Redmine for project management; and Git for version control. The programming languages under consideration include C, C++, Python, and MATLAB. Network simulation tools such as NS-3 may also be used, with the role participating in tool selection.
The position is based at the Ariake office in Koto, Tokyo. The posting states that office attendance is the basic arrangement, with partial remote work available. The location-change provision includes the stated workplace and company-designated locations, including places where telework is performed. Indoor smoking is prohibited throughout the workplace. A company-designated PC is provided according to the employee’s preference. The selection process is document screening, a first interview, a second interview with an aptitude test, and a final interview.
