• Understand and analyze existing system architecture and system-level requirements

• Create and maintain technical specifications in Japanese and English

• Design, develop, and maintain high-performance, scalable software

• Implement solutions using TypeScript, Rust, Ruby, and Python

• Develop and deploy software in a Linux environment (Rocky Linux 8)

• Implement and operate distributed storage systems, with a focus on CephFS

• Contribute to architecture design for large-scale HPC systems

• Configure, operate, and optimize workload scheduling using OpenPBS (Altair)

• Collaborate with cross-functional and offshore teams to ensure robust system design

• Tune, troubleshoot, and optimize system performance and reliability

Requirements

• Strong hands-on development experience with:

  • TypeScript

  • Rust

  • Ruby

  • Python

• Practical experience working on Linux systems (Rocky Linux or equivalent)

• Hands-on experience with distributed storage systems, specifically CephFS

• Solid understanding of High-Performance Computing (HPC) concepts

• Experience with OpenPBS (Altair) or similar job schedulers

• Deep understanding of system design and software architecture

• Proven experience working on complex, large-scale systems

• Strong problem-solving and analytical skills

• Experience collaborating with on-site customers and offshore development teams

• Comfortable working in semiconductor or hardware-adjacent environments

• Japanese: Business level (JLPT N2 or above)

• English: Business level

• Ability to communicate technical concepts clearly across teams and stakeholders

Nice to have:

• Knowledge of semiconductor manufacturing processes or inspection equipment

• Experience with CI/CD tools (Jenkins, Bamboo, GitLab, Bitbucket)

• Exposure to on-site + offshore execution models

• Experience with other distributed file systems or storage technologies

• Knowledge of container technologies (Docker, Kubernetes)

Benefits

• Work on mission-critical systems supporting advanced semiconductor manufacturing

• Exposure to cutting-edge inspection technologies, HPC, and distributed computing

• Long-term engagement with a global semiconductor equipment leader

• Collaboration in a bilingual, international engineering environment

• Clear progression toward architect-level roles and broader technical leadership paths
