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
