Senior System Engineer

About the Role

As a Senior System Engineer, you will be a key member of the IT team responsible for delivering exceptional workplace technology support, managing corporate IT systems, and continuously improving IT operations across APAC.

This is a senior individual contributor role. You will own local IT support for the Tokyo office while also supporting remote employees across the APAC region. The ideal candidate is not simply a helpdesk operator, but a proactive IT professional who can identify operational gaps, improve processes, automate repetitive work, and partner effectively with global IT, Security, and business teams.

You will support a mixed Mac and Windows environment, administer core workplace tools, manage device and SaaS lifecycles, support employee onboarding and offboarding, and contribute to security and audit readiness. This role is approximately 70% IT operations and support, and 30% project work and process improvement.

What You’ll Do

• Provide high-quality local IT support for the Tokyo office and remote IT support for employees across the APAC region.
• Own day-to-day workplace technology support for employees, ensuring a responsive, professional, and customer-centric support experience.
• Manage and support Mac and Windows endpoints, including provisioning, troubleshooting, lifecycle management, and asset tracking.
• Administer and support core workplace systems, including Google Workspace, Slack, Zoom, Okta, Jira, Confluence, Notion, Jamf, and Workspace ONE.
• Support identity and access management workflows, including account provisioning, access requests, SSO-related troubleshooting, and offboarding activities.
• Manage MDM operations and endpoint compliance processes across corporate devices.
• Support SaaS application lifecycle management, including licensing, access reviews, renewals, usage tracking, and vendor coordination.
• Partner with HR, Security, Finance, Legal, and other internal teams to support employee onboarding, offboarding, and role changes.
• Maintain IT asset inventory, purchasing workflows, hardware logistics, and vendor relationships for the Japan office and APAC users.
• Apply and support corporate IT and security policies, including endpoint standards, access controls, audit requirements, and compliance processes.
• Identify opportunities to improve IT support processes, reduce manual work, and increase operational efficiency through documentation, tooling, and automation.
• Create and maintain clear documentation, runbooks, knowledge base articles, and process guides for IT operations.
• Collaborate closely with global IT, Security Engineering, and regional stakeholders to deliver consistent and scalable IT services.
• Provide support during urgent incidents or business-critical issues when needed, although regular on-call responsibility is not expected.

What We’re Looking For

• 5+ years of experience in Corporate IT, Workplace Technology, Systems Engineering, IT Operations, or a similar role.
• Strong hands-on experience supporting employees in a fast-paced technology or global business environment.
• Deep understanding of IAM, MDM, endpoint management, and modern workplace collaboration tools.
• Experience administering or supporting systems such as Google Workspace, Okta, Jamf, Workspace ONE, Slack, Zoom, Jira, Confluence, or similar platforms.
• Strong troubleshooting skills across Mac, Windows, SaaS applications, identity systems, and endpoint management tools.
• Experience supporting employee onboarding and offboarding processes, including device provisioning, account setup, access management, and asset recovery.
• Ability to manage IT assets, vendor relationships, purchasing processes, and license usage with strong operational discipline.
• Strong customer-service mindset with the ability to support employees professionally, calmly, and effectively.
• Business-level English communication skills.
• Business-level Japanese communication skills.
• Ability to work independently in Tokyo while collaborating closely with global and regional teams.
• Strong ownership mindset, structured problem-solving skills, and the ability to drive improvements without waiting for detailed instructions.
• Experience writing documentation, improving workflows, and making IT operations more scalable and repeatable.
• Practical technical aptitude, including the ability to understand systems deeply and automate or streamline repetitive work where appropriate.
• Degree not required; equivalent hands-on experience is strongly valued.

Nice to Have

• Experience working in a global technology company or high-growth tech environment.
• Experience supporting distributed teams across multiple countries or time zones.
• Experience leading or independently driving IT systems, process improvement, automation, or workplace technology projects.
• Experience improving onboarding, offboarding, asset management, SaaS management, or access management workflows.
• Familiarity with scripting, API-based automation, or lightweight automation using tools such as Bash, Python, PowerShell, or SaaS platform APIs.
• Experience supporting security audits, access reviews, endpoint compliance, or IT control processes.
• Experience working closely with Security, Engineering, HR, Finance, Procurement, and Legal teams.

What Success Looks Like

Within the first 6 to 12 months, you will have established strong ownership of IT support across the Tokyo office and APAC region. Employees will receive consistent, high-quality support, core IT processes will be more efficient and better documented, and regional IT operations will run with greater clarity, reliability, and scalability.

You will be expected to move beyond reactive support by identifying recurring issues, improving workflows, strengthening operational standards, and partnering with global teams to deliver a world-class IT experience for employees.

Who Will Thrive in This Role

You will thrive in this role if you are hands-on, highly accountable, and passionate about delivering excellent employee support. You are comfortable working independently, but you know how to collaborate with global stakeholders. You enjoy solving ambiguous problems, improving broken or manual processes, and building scalable IT operations.

This role is best suited for someone who brings strong technical judgment, customer empathy, and operational ownership. We are looking for someone who can both support users effectively and raise the bar for how IT services are delivered across the region.
