Hardware Engineer

This open hardware engineering position covers the design and manufacture of small satellites. Assignment may focus on structural design, thermal design, communications design, electrical design, embedded software, or FPGA development according to the engineer’s expertise and interests.

Structural responsibilities may include spacecraft structure and equipment-layout design using 3D CAD, structural analysis, and assembly. Thermal work includes thermal-control parameter design, thermal analysis, thermal instrumentation, and thermal-environment testing. Communications work covers radio and antenna design, link calculations, verification testing, and development of systems such as VDES and satellite IoT while interpreting ITU and IMO standards.

Electrical responsibilities include power and signal harness design, board specifications, electrical verification testing, component selection for radiation, vacuum, and temperature-cycle environments, and electrical-margin management. Embedded software engineers develop onboard satellite software and control interfaces with satellite equipment. The company uses Rust and designs for OTA updates. FPGA engineers design and verify onboard equipment for communications processing, sensor-data acquisition, and equipment control, including hardware description, functional verification, and board-level debugging.

Across specialties, the role requires considering how design decisions affect the complete satellite system. Engineers participate in a feedback loop of analysis, testing, launch, in-orbit verification, and incorporation of results into subsequent designs. The work also involves identifying unexpected problems during testing and analysis and returning findings to the design.

The development environment includes SolidWorks and finite-element analysis tools, Thermal Desktop, circuit-design tools such as Altium Designer, Rust, C, Git, GitHub, VHDL, Verilog, ModelSim, Slack, and Google Workplace. The organization is introducing pull-request practices, CI-based automated verification, and test-data databases. The team includes approximately 200 employees as of March 2026, and onboarding includes pair work with experienced engineers and structured learning using internal knowledge and actual hardware. The work location is the Ariake office in Koto, Tokyo; office attendance is generally required, with limited remote work available.
