Note: The job is a remote job and is open to candidates in USA. Jabil is a trusted partner for leading brands, providing engineering and manufacturing solutions. The HVAC & Liquid Cooling System Architect will define and architect advanced HVAC systems for data-center applications, engaging with customers and leading the technical direction of projects.

Responsibilities

• Drive system concepts and partitioning; define architecture and configuration baselines, interfaces, and KPI’s for HVAC systems, chillers, and CDU-based liquid-cooling platforms
• Translate market and customer needs into system-level requirements with validation traceability; maintain system block diagrams and ICD (interface control documents)
• Execute early trade-off analyses (cost, schedule, efficiency, capacity, performance and footprint) and maintain compliance matrices / risk registers
• Define control architecture (sensors/actuators, supervisory control, sequencing, alarms), BMS/DCIM integration, and protocol strategies (BACnet/IP, Modbus TCP/RTU, SNMP)
• Incorporate cybersecurity requirements and network segregation for connected equipment
• Lead technical discovery, drive performance/cost/schedule feasibility studies, and present trade-offs and recommendations to both external and internal stakeholders
• Support competitive proposals (RFI/RFQ/RFP) and contribute to SOW and ROM estimates
• Lead multi-disciplinary design reviews (mechanical, thermal, hydraulic, controls, electrical, firmware, manufacturing test)
• Align architecture concepts and tradeoffs with customer and Jabil executives/stakeholders; create handoff architecture packages for development teams
• Provide DFMEA/PFMEA inputs, and conduct technical reviews to ensure performance, safety, reliability and field serviceability
• Ensure designs address applicable ASHRAE requirements and Handbook guidance
• Architect for product safety compliance for HVAC/chiller/CDU platforms, with standards and codes applicable to product scope and region
• Support HVAC and liquid-cooling system modeling and analyses (loads, thermal transients, refrigerant circuit selection, hydraulic loops, heat-exchanger sizing, airflow/CFD, acoustics, and partial-load efficiency)
• Support component selections (compressors, heat exchangers, pumps, valves, filtration, sensors, and controls hardware) and ensure reliability, serviceability, and lifecycle considerations
• Architect for DFM/DFA/DFT, part reuse, commodity strategies, and supply chain resilience; support build readiness (prototype/pilot/ramp) and resolve factory integration issues
• Align with sourcing on vendor roadmaps; anticipate obsolescence, regulatory, and regionalization risks; support cost modeling and BOM sourcing strategies for critical cooling components and long-lead items

Skills

• Bachelor's degree in Electronics/Energy/Controls/Mechatronics or related field is required
• 10+ years of experience in thermal management product and system design (commercial/industrial), including 5+ years in systems architecture or platform leadership with proven front-end design ownership
• Strong knowledge of HVAC and cooling topologies (chillers, hydronic systems, CDUs, pump skids, refrigerant-based systems), thermodynamics, hydraulics, and acoustics
• BMS/DCIM protocol expertise (BACnet, Modbus, SNMP); familiarity with gateways and secure IP/cloud integration patterns
• Familiarity with relevant simulation tools (MATLAB/Simulink, EnergyPlus) and CFD/FEA tools (ANSYS Fluent / Icepak)
• Excellent English communication (written/verbal); able to present to customers and internal stakeholders with clear technical trade-off narratives and strong executive-level communication
• Comfortable coordinating across time zones and cultures; drive alignment among remote teams
• Organized, proactive, and outcome-focused; able to mentor engineers and elevate cross-functional collaboration across design, manufacturing, sourcing, quality, and customer teams
• Ability to travel (internationally and domestically) to customers, events, workshops, external labs, and Jabil manufacturing locations during key project phases
• Master's degree in a related discipline is a plus
• ASHRAE Membership/certification is a plus
• Experience with data-center critical cooling, chillers, CDUs, or closely related liquid-cooling infrastructure is strongly preferred
