Rapyuta Robotics is seeking a Senior Electronics Engineer to join its mechatronics team in Tokyo. The company develops robotics platforms and solutions for automating demanding, dirty, and dangerous jobs, leveraging advanced control and coordination technologies.
In this hands-on role, you will design, validate, and support the electronics for Rapyuta's ASRS products (robots, elevators, battery exchange cabinets, Guardian) and AMR (autonomous mobile robot) products. You will serve as the senior electronics engineer on the ground in Japan, working closely with engineering teams in India and China. Much of your time will be spent at the bench, with manufacturing partners, and at customer sites.
Key responsibilities include:
- Design and own PCBAs for robots, elevators, battery exchange cabinets, and Guardian systems: schematics, layout review, BOM, and release documentation
- Assemble, rework, bring up, and validate prototypes in Tokyo, including power, ESD/EMC pre-tests, thermal and functional testing with written reports
- Support Japanese manufacturing partners and supply chain: design handover, inspection and test fixtures, first-article checks, and end-of-life part alternatives
- Serve as escalation engineer for electronics issues at Japanese customer sites; analyze field returns, lead root-cause analysis, and drive corrective actions to closure
- Design, build, and maintain test jigs and fixtures for production and field returns
- Contribute to next-generation robot electronics (motor control, power, battery) with engineering teams in India and China; review designs for manufacturability and field reliability
- Perform electronics and electrical work on AMR, autonomous forklift, and ASRS elevator systems, including wiring, harnesses, and power distribution
Requirements:
- 7+ years designing electronic hardware for mass production in robotics, automotive, industrial automation, or similar fields
- Solid analog, digital, and power design expertise: DC/DC conversion, battery and charging circuits, BLDC/PMSM motor drive, protection (ESD, surge, reverse polarity)
- Microcontroller-based design and interfaces: GPIO, PWM, ADC, I2C, SPI, UART, CAN
- Proficiency with schematic and layout tools (KiCad, Altium Designer, or equivalent); oscilloscope, logic analyzer, electronic load, soldering, and rework
- B.Sc. or M.Sc. in Electrical/Electronics Engineering or equivalent
- Business-level English
Preferred qualifications:
- EMC/ESD design and pre-compliance testing (IEC 61000-4-2, CE, FCC)
- Design transfer to contract manufacturers (DFM, DFT, test fixtures); lithium-ion battery pack or BMS experience
- Electrical design: wiring and harness design, power distribution, control panels
- Python or scripting for test automation
- Conversational Japanese
