Work as a satellite systems engineer across satellite design, development, testing, and operations, helping build communications infrastructure and direct-to-device connectivity.
About this role
This role leads architecture design for the wireless communications section covering rocket vehicles and ground stations, from overall system architecture through implementation of antennas and RF circuits. The work focuses on establishing antenna design and verification processes for high-speed rocket vehicles and maintaining communication quality in harsh environments.
Responsibilities include communication and antenna architecture design, link-budget calculations, modulation and demodulation method selection, and optimization of antenna placement while considering the vehicle shape. The engineer develops and verifies S-band antennas for telemetry and command functions and GNSS antennas, including design, prototyping, electromagnetic-field analysis, radiation-pattern measurements, and construction of verification processes using physical hardware.
The role also supports wireless-equipment development, including RF front-end specification definition and design support for signal-processing systems using FPGA and SoC technology, followed by prototype evaluation. Additional responsibilities include leading system integration tests, EMC testing in an anechoic chamber, and outdoor long-distance communications tests.
The position involves technical coordination with external manufacturing and analysis partners. It also includes handling technical standards conformity certification and related matters under Japan's Radio Act.
The stated work location is the Tokyo branch in Koto-ku, Tokyo. The scope of work may change to duties determined by the company.
