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 role designs and develops communication systems for ultra-small artificial satellites, with a primary focus on signal-processing design using software-defined radio. The work covers the design and development needed to integrate multiple technical elements into a complete satellite system. Over time, the role is expected to expand beyond communication design to include overall satellite system design.
Responsibilities include signal analysis using software-defined radio, including digital modulation and demodulation; designing and implementing SDR architectures for wireless communication systems; and designing wireless communication equipment using FPGAs, DSPs, and microprocessors. The engineer also evaluates working equipment with measurement instruments such as oscilloscopes, logic analyzers, spectrum analyzers, and network analyzers. Additional responsibility includes managing external suppliers for the design and manufacture of SDR boards.
The posting states that space and satellite technology can be learned after joining, and that engineers without prior industry experience are welcome. The role covers the full process from upstream design through downstream development and completion, with responsibility for the communication design of an ultra-small satellite from initial design to finished product.
Named tools and technologies include Windows, GitHub Projects V2, GitHub Issues, Redmine, MATLAB, Simulink, C, C++, Python, VHDL, Verilog, FPGA, and NI USRP. A company-designated PC is provided according to the employee's preference.
The position is assigned to the Radio Infrastructure Department, which consists of one department head, three manager-level members, and five staff members. The posting describes manager-level employees as mainly in their 40s and staff members ranging from their 20s to their 50s. The work involves collaboration with countries in Europe, North America, Asia, Africa, and South America, as well as joint research and development projects with space agencies including ESA.
The work location is the Ariake office in Koto-ku, Tokyo. Work is generally performed in the office, with limited remote work available. The stated selection process is document screening, a first interview, a second interview with an aptitude test, and a final interview. The scope of duties may change to duties designated by the company.
