Job Description

[Business Overview]
Visban Corporation develops innovative technologies to realize next-generation wireless networks using millimeter-wave and terahertz-wave bands. We pioneer the future of communications through our proprietary "V-Mesh" technology, which integrates unique glass-based repeaters with AI-driven mesh network software. Backed by a strong research foundation and credibility—including investments from UTokyo IPC and selection for numerous public grants—our environment allows engineers to take hands-on leadership in shaping cutting-edge fields.

[Job Overview]
・Characterization and performance measurement of RF active components including transceivers, mixers, PAs, and LNAs
・Measurement of key RF parameters such as gain, noise figure, linearity (IP3/P1dB), EVM, and power consumption
・Execution of S-parameter, insertion loss, isolation, and return loss measurements using VNA
・Design and implementation of measurement setups integrating instruments such as VNA, SA, and SG
・Development of measurement automation scripts using Python
・System-level verification of mmWave wireless devices, including EVM, SNR, and data rates
・Documentation of measurement procedures, test plans, and data analysis results

[Project Structure and Engineer Roles]
The development team consists of multidisciplinary specialists handling everything from hardware implementation to AI-driven communication control.
・Mechanical Design Engineers: Chip mounting on glass substrates and structural design of radio relay device enclosures
・Simulation Engineers: Design of optimal wiring and antenna radiation patterns using radio wave propagation simulations
・Embedded Engineers: Development of hardware-software interfaces and implementation of device control systems
・Software Engineers: Development of optimal repeater placement algorithms and overall system architecture
・Machine Learning Engineers: Collection and analysis of propagation data and development of control algorithms to optimize beam direction
・AI Engineers: Construction of core AI logic for dynamic control of radio wave propagation paths

[Position Highlights]
・Research-oriented environment with a majority of employees holding PhDs
・Opportunity to engage in both advanced research and business development as V-Mesh technology evolves

[Work Environment]
・Hybrid work system with office attendance typically 1–2 times per week for prototype testing or site visits
・Office located within a 1-minute walk from the station
・Company-sponsored weekly office lunch every Wednesday
・Collaborative development environment including both full-time employees and external contractors

[Impact and Achievements of Global Employees]
・Diverse team with nationalities including the USA, UK, China, South Korea, France, Sweden, Italy, and Japan
・Two-thirds of the total workforce comprised of international members
