  • Collaboration & Stakeholder Engagement:
    • Engage with customers and partner infrastructure teams to align solutions with enterprise standards.
    • Collaborate with internal technical teams and project stakeholders to support end-to-end delivery.
    • Prepare infrastructure and operational documentation and lead customer review sessions for sign-off.
  • Operational Readiness:
    • Implement observability tools and dashboards for real-time monitoring and alerting.
    • Design and test disaster recovery (DR) solutions to meet business continuity goals.
    • Ensure operational best practices through the delivery of SOPs and infrastructure runbooks.


Required Skills & Qualifications:

  • Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
  • 10+ years of experience in Infra and Technical Architecture, with at least 3 years in cloud-native architecture roles.
  • Hands-on experience with Oracle Cloud Infrastructure (OCI) or any public cloud services.
  • Strong knowledge of network architecture, security, firewall rules, and microservices architecture.
  • Proficient in Docker image creation, Kubernetes cluster management, and Linux OS administration.
  • Solid experience with DevOps practices, including CI/CD and Infrastructure-as-Code (IaC).
  • Expertise in observability tools like Prometheus, Grafana, ELK, or Splunk.
  • Experience creating and delivering Standard Operating Procedures (SOPs) for infrastructure and operations.
  • Fluent in both English and Japanese (written and spoken).
  • Strong interpersonal, documentation, and presentation skills.


Preferred Qualifications:

  • Telecom domain experience, particularly in BSS/OSS systems.
  • Familiarity with Oracle BRM, PDC, and ECE applications.
  • Knowledge of tools such as Terraform, Ansible, Jenkins, and Git.
