Head of Data Center Infrastructure

PT. Indosat Tbk; Jakarta Pusat; On-site; IDR 600,000,000 - 1,200,000,000; Full time

Job summary

PT. Indosat Tbk is seeking a Head of Data Center Infrastructure to oversee the physical facility infrastructure for high-density GPU cloud sites, including power, cooling, and space planning.

You will partner with third-party providers to ensure reliable operation and drive capacity planning at scale. The role requires extensive experience in data center facilities engineering, leadership, and a track record with hyperscale or AI/GPU deployments, preferably in the APAC region with knowledge of

Qualifications

• 8+ years in data center facilities engineering or critical infrastructure operations, with 3+ years in a leadership role.
• 2-3+ years of hands-on experience with high-density compute facilities (GPU/HPC clusters), including exposure to liquid cooling systems (direct-to-chip and/or rear-door heat exchangers) — traditional air-cooled DC background acceptable if paired with demonstrated ability to ramp on liquid cooling technology.
• Strong technical grounding in facility power systems — AC power distribution (utility feed, generators, switchgear, UPS, PDUs) and exposure to DC power architectures (battery systems, emerging rack-level DC distribution) — at scale, with redundancy design (N+1, 2N).
• Strong technical grounding in facility cooling systems (CRAC/CRAH, chillers, air handling) at scale.
• Experience managing colocation/DC provider relationships and enforcing facility SLAs.
• Track record commissioning or scaling facility infrastructure for hyperscale or AI/GPU cloud deployments.
• Comfortable operating at the interface of contracts, MEP engineering, and operations.
• Added Advantage: Experience with next-generation high-density GPU rack architectures or equivalent hyperscale AI infrastructure deployments.
• APAC/Indonesia data center market experience, including local utility/regulatory context (PLN, environmental permits).
• Uptime Institute Tier III/IV facility background.

Responsibilities

• Lead facility infrastructure strategy and operations across GPU data center sites, including power, cooling, capacity, and environmental systems.
• Manage data center providers and ensure compliance with power, cooling, and facility SLAs for high-density GPU environments.
• Oversee power and advanced liquid cooling infrastructure to support current and future GPU cluster deployments.
• Drive facility capacity planning, site expansions, energy efficiency (PUE), and operational readiness.
• Own MEP systems, fire & life safety, preventive maintenance, commissioning, and incident response processes.
• Build and lead the Infrastructure team while providing regular updates on facility health, risk, and capacity to senior leadership.
