The organisation is a growing technology business developing AI and robotic solutions to help address workforce challenges and support service delivery. Its work brings together product development, cloud infrastructure and AI robotics, creating an environment where workplace technology and reliable IT operations play an important supporting role.
The technology team works in English and collaborates across disciplines. It values practical, hands-on problem-solving, clear communication and secure, dependable systems. Joining at a stage of continued growth offers the opportunity to improve essential IT operations, contribute to stronger security and compliance practices, and help shape how the team works. You will be part of a collaborative, internationally minded environment where your technical expertise can have a visible impact on employees’ day-to-day experience.
As a Senior IT Engineer, you will help maintain and improve the organisation’s corporate IT environment. The role is primarily focused on workplace IT, with some network engineering, and involves hands-on responsibility for employee devices, internal systems and on-premises infrastructure. You will support users throughout the device and access lifecycle, troubleshoot issues, maintain accurate records and coordinate IT changes across multiple sites in Tokyo.
You will also apply endpoint security controls, support vulnerability remediation and contribute to IT security policies and audit readiness. Working with the DevSecOps Engineer, you will carry out routine checks and first-line troubleshooting for Linux and Kubernetes-related systems, escalating complex technical issues as appropriate. The position does not involve public-cloud infrastructure administration. Two engineers will join as individual contributors; one will be appointed to a manager role after joining, with the director deciding who takes on the appointment.
Demonstrated hands-on experience in corporate or internal IT, particularly device management, employee support, access management and administration of IT systems.
Practical experience configuring and troubleshooting enterprise networks, including L2 switches, L3 routers, VPNs, firewalls or security gateways.
Sound knowledge of TCP/IP, DNS, VPNs and network security practices.
Experience administering Linux distributions such as Ubuntu or RHEL.
Experience with configuration management or automation tools such as Ansible.
Knowledge of endpoint and network security practices, including patching and vulnerability remediation; familiarity with EDR, IDS/IPS, SIEM or SOAR technologies.
Working familiarity with Docker and Kubernetes fundamentals; deeper container-platform experience, including Helm or Argo CD, is an advantage.
Strong troubleshooting, documentation, communication and collaboration skills.
Professional working Japanese for speaking, reading, writing and vendor communication; around JLPT N2 proficiency is preferred, but certification is not required. Business-level English is needed for the technology team environment.
Network or information security certifications, and experience with monitoring or logging tools such as Prometheus, Grafana or New Relic, are advantageous.
