Kansai or Kanto, Japan • Full-time

Not a ticket-closer.

Not a help desk technician.

A Technical Architect.

A Client Advocate.

A Systems Thinker who doesn’t just fix things, but builds trust and makes technology disappear.

You’re the one who sees through the noise to the root cause. You crave complexity but deliver simplicity. You’re ready to stop putting out fires and start architecting fireproof solutions for ambitious clients who rely on robust networks and Apple technology.

This isn’t a back-office IT role. You are the front line of our reputation, a trusted partner embedded with our clients.

If you’re tired of being just another cog and hungry to become a linchpin, this is for you. 🚀

YOU WON'T BUILD A CAREER LIKE THIS ANYWHERE ELSE IN JAPAN.

Sentree: We are not a typical IT provider. We are a strategic consulting firm for businesses built on Apple. We operate on the Entrepreneurial Operating System (EOS), a framework for clarity, accountability, and results. We don’t just manage IT; we deliver a competitive advantage by making our clients’ technology seamless, secure, and powerful.

WHO YOU ARE

A calm, technical force who is allergic to quick fixes and low standards. You’re driven by a deep need to understand how things work and make them work better.

You:

Are a systems thinker, wired for both technical logic and human empathy.
Translate complex technical challenges into clear, actionable solutions.
Thrive on accountability and operate with a consultant’s mindset, not an employee’s.
Are a natural documenter who understands that clarity is kindness.
Might be a systems administrator, a sharp consultant, or a technical lead who found corporate too slow or other IT services work too shallow.
Are a fast learner, a sharp communicator, and respected under pressure.

HOW YOU THINK & OPERATE

You lead with strategic advice first, then deliver expert execution.
You manage complex projects and personalities without drama, making grounded decisions quickly.
You prefer lean, high-performing teams over bloat and buzzwords.
You instinctively audit, troubleshoot, and solve for resilience without needing direction.
You understand that trust is built through consistent, high-quality delivery.

WHAT SUCCESS LOOKS LIKE (WITHIN 6 MONTHS) 🎯

You are a trusted partner. Clients don’t just bring you problems; they bring you their plans, seeking your strategic advice before they make a move.
Your environments are silent. The networks and systems you manage are so stable and well-architected that they rarely have issues.
You are a benchmark for quality. Your project delivery and documentation are the standard the rest of the team aspires to.
You are driving our standards. You've actively contributed to our internal best practices, making the entire company sharper.
You own your outcomes. You are fully integrated into our EOS rhythm, confidently reporting on your metrics and driving your initiatives forward.

WHAT YOU’LL DO

Architect & Deploy: Design, build, and maintain robust and secure IT environments (macOS, iOS, MDM, Windows, Networks, Cyber Protection) for our clients.
Own Client Outcomes: Be the single point of technical confidence. Run discovery, execute projects, provide proactive maintenance, and deliver strategic guidance.
Drive R&D: Research and weaponize new technologies and techniques to keep us and our clients at the bleeding edge of the Apple ecosystem.
Systematize Everything: Build lean, scalable workflows and create high-quality documentation for everything you touch.
Lead with Accountability: Operate within our EOS framework, owning your scorecard and initiatives to drive measurable results.

YOUR TOOLKIT: ESSENTIALS & ADVANTAGES 🛠️

Essential: Deep, hands-on expertise in advanced macOS/iOS troubleshooting and systems administration.
Essential: Proven ability architecting and deploying MDM systems (Mosyle, Jamf, etc.) and enterprise-grade Wi-Fi (Meraki, Ubiquiti, etc.).
Essential: Professional-level English and business-level Japanese communication skills.
Advantage: Proficiency with scripting, Active Directory, and cloud solutions (Google Workspace, Microsoft 365).

THIS IS NOT FOR YOU IF...

You see IT as a checklist of tickets to be closed.
You wait to be told what to do or need the "how" spelled out.
You avoid tough, direct conversations or shy away from full ownership.
You think "good enough" is good enough.
You are looking for a fully remote role (this is a hands-on, client-facing position).
You are uncomfortable with the radical transparency of a system like EOS.

SOUND LIKE YOU?

This is your chance to do the best work of your career and build something rare and trusted in the Japanese market.
