Job description

In Schneider Electric everything we do promotes progress and sustainability for all — our colleagues, customers, partners, and the communities and societies where we live and work. From the products, software, and services driving the digital transformation of energy management and automation to corporate citizenship and volunteer activities, we make an impact by helping people and organizations become more resilient and efficient, more electric and digital.

Which is where you come in. Working at Schneider Electric means working toward a cleaner, better world. You're part of a global team built on inclusion, mastery, purpose, action, curiosity, and teamwork, turning sustainability ambitions into actions.

The Role:

We are in search for an experienced Principal System Architect (Pre-Sales) – Mechanical to lead the design of innovative cooling and thermal solutions for strategic data center customers.

What will you do?

Thermal System Design (Core Engineering)

Design complete cooling and Thermal management systems for datacenter solutions:

• Primary chiller plant: water-cooled and air-cooled configurations, sizing, redundancy strategies (N, N+1, 2N).
• Heat rejection systems: cooling towers, dry coolers, adiabatic cooling, seasonal performance modelling.
• Chilled water distribution: primary/secondary loop design, variable flow optimization, delta-T management.
• Precision air systems: CRAH/CRAC sizing, hot aisle/cold aisle containment, airflow design.
• In-row cooling and rear-door heat exchangers (RDHx) for high-density environments.
• Liquid cooling systems: CDU sizing for 30–200+ kW clusters, warm water interfaces (up to 45°C), OCP OLC-compliant manifolds.
• AI DC thermal design: GPU cluster-scale cooling, NVL72/GB200 CDU configuration, hybrid air+liquid architectures.
• Energy modeling: PUE contribution from cooling, WUE analysis, free-cooling availability, economization strategies.

Solution Engineering Deliverables

Produce all cooling engineering outputs for bids:

• Cooling load calculations and psychrometric analysis.
• Equipment sizing schedules and specifications.
• P&ID diagrams (concept and scheme level).
• Piping layout sketches and CDU configuration schedules.
• Bill of Materials (BOM) for cooling scope.
• OG vendor specifications (third-party product selection).
• Design handover packages when solutions are won

Customer & Consultant Engagement

• Lead cooling-scope technical discussions with customers; defend design decisions at engineer-to-engineer level.
• Conduct cooling-specific technical workshops with design consultants; embed Schneider standards in RFP briefs.
• Support EPC contractor engagement: pre-construction design reviews, technical clarifications, interface resolution.
• Present cooling technology roadmap to primary accounts, especially AI DC thermal futures.
• Build and maintain direct technical relationships with customer mechanical engineering teams .

Fighting Unit & Bid Support

• Work as core member of the account fighting unit: SSA (solution strategy), System Architect Presales - Electrical (power train), System Architect Presales - Mechanical (thermal train), System Architect Presales - Digital and KAM (customer relationship).
• Co‑design with System Architect – Electrical: align cooling loads with electrical BOM, CDU power inputs, BMS integration points.
• Submit qualifying bid designs through Principal Architect review; address technical feedback.
• Participate in win/loss debrief reviews: capture cooling-scope decisions and lessons for reference architecture updates.
• Support solution integration: ensure power design is competitive, technically correct, and aligned with customer needs.

Technical Standards & Continuous Improvement

• Design to Principal Architect-defined cooling reference architectures; document deviations when customer requirements necessitate variation.
• Provide active project inputs to Principal Architect for reference architecture evolution.
• Propose new OG products for qualified list when bids require capabilities not currently available.
• Complete required technical certifications (ASHRAE, Uptime Institute ATD, OCP OLC).
• Deliver internal technical sessions to zone SSAs on cooling fundamentals, AI DC thermal management, and liquid cooling.

What qualifications will make you successful?

• Degree in Mechanical Engineering or Building Services Engineering (MEng or BE preferred)
• Min 8–14 years in datacenter cooling design, commissioning, or presales; minimum 5 years specifically in Data Center environments.
• Demonstrated design experience: chiller plant, CRAH systems, chilled water distribution (≥2 MW cooling capacity).
• Has working experience and knowledge of liquid cooling: CDU application, RDHx, basic manifold design.
• Experience producing engineering deliverables: cooling calcs, P&IDs, equipment schedules, BoMs.
• Ability to present and defend cooling designs to customer mechanical engineering teams. Familiarity with ASHRAE 90.4 and Uptime Institute Tier criteria for cooling.
• Have Uptime Institute Accredited Tier Designer (ATD) certification – cooling module will be an added advantage.
• Has ASHRAE Data Center Academy or similar formal certification will be an added advantage.
• Direct AI DC experience: GPU cluster cooling, NVL72/HGX thermal requirements, CDU sizing for 100kW+ densities. Has Background with hyperscalers (AWS, Google, Meta, Microsoft, Equinix) or Tier 1 consultants (Arup, WSP, Mott MacDonald, Syska).
• Immersion cooling experience (single-phase or 2-phase design/feasibility).
• Presales or solutions engineering background.
• Willing to travel across East Asia region.

What's in it for me?

• High-visibility role working on strategic accounts and transformative projects
• Opportunity to design solutions that make a real impact on sustainability and efficiency
• Supportive, collaborative environment that values technical expertise and growth
• Professional development opportunities including certifications and mentorship
