Location: Toyama, Japan

Work model: On-site (resident / customer-facing role)

Domain: Embedded Software, Hardware / Semiconductor-related Systems

This is an on-site embedded software engineering role focused on C++ development and coordination within a complex, hardware-integrated environment. You will work directly at the customer site, acting as a technical contributor and embedded software coordinator, supporting system-level development, cross-team alignment, and verification activities. The role requires strong hands-on C++ expertise, solid understanding of embedded/real-time systems, and the ability to operate fluently in Japanese and English technical environments.

Responsibilities

• Act as an on-site embedded software engineer and development coordinator
• Understand and analyze existing system architecture and system-level requirements
• Collaborate closely with multiple customer departments to gather and clarify requirements
• Analyze requirement dependencies and impact across modules
• Create and maintain technical specifications in Japanese and English
• Perform object-oriented analysis and design, coordinating with dependent module owners
• Develop and verify C++ software based on approved designs
• Ensure high standards of version control, quality control, unit testing, and code coverage
• Verify software behavior on actual hardware devices and resolve defects identified during testing
• Report progress, risks, and technical issues in line with customer expectations
• Support QA certification and validation activities as required
  
  

Requirements

• 6+ years of practical C++ development experience in VxWorks and/or Windows environments
• Proven experience in object-oriented analysis and design, applying design principles in production systems
• Experience with multi-layer application development and system integration
• Ability to independently develop and debug complex C++ applications
• Strong problem-solving skills and disciplined approach to software quality
• Multi-threading, synchronization, and thread prioritization experience
• IPC mechanisms (e.g. shared memory, message queues, pipes, sockets) experience
• Memory optimization in embedded or performance-critical systems experience
• Proven ability to create clear technical documentation in both Japanese and English
• Japanese: Native level / JLPT N1 or above
• English: Business level (technical discussions, documentation, coordination)
• Strong teamwork and communication skills in cross-functional environments
• Experience working on-site with customers or in resident engineer roles
• Comfortable coordinating between local customer teams and offshore / overseas teams
  
  

Nice to have:

• Experience with VxWorks build environments, including makefiles
• Knowledge of VxWorks system APIs, internal tasks, memory management
• Exposure to semiconductor production environments
• Understanding of semiconductor industry standards such as SECS/GEM, EDA
• Experience developing device or machine control software
• Prior experience on on-site + offshore execution models
  
  

Benefits

• A deeply technical, hands-on embedded role in a production environment
• Direct exposure to hardware-integrated and semiconductor-related systems
• Long-term engagement on complex, real-world embedded software
• A role combining development, coordination, and customer-facing responsibility
• Work in a highly structured Japanese engineering environment with global collaboration
