HVAC & Liquid Cooling System Architect​/Project Manager

HVAC & Liquid Cooling System Architect

At Jabil, we are proud to be a trusted partner for the world's top brands, offering comprehensive engineering, supply chain, and manufacturing solutions. With 60 years of experience across industries and a vast network of over 100 sites worldwide, Jabil combines global reach with local expertise to deliver both scalable and customized solutions. Our commitment extends beyond business success as we strive to build sustainable processes that minimize environmental impact and foster vibrant and diverse communities around the globe.

This role is part of Jabil's Renewable & Energy Infrastructure (R&EI) division, partnering with global customers to define, architect, and industrialize advanced HVAC and liquid-cooling systems for scalable manufacturing across different regions. Main emphasis will be on data-center critical cooling applications such as chillers, CDUs (coolant distribution units) and related refrigerant/hydronic systems.

As an HVAC & Liquid Cooling System Architect within Jabil, you will work with the BUs and Sales team to engage with customers, assess product technologies and manufacturing complexities, and provide guidance to the BU and Sales teams in developing the appropriate Jabil solutions and capabilities to support business opportunities and strategic partnerships.

The SA/SME will lead system-level architecture, requirements, and trade-offs in the front-end of design, set the technical direction, and align clear handoff packages to development and factory teams. He/she will ensure solutions will meet performance, safety, compliance, energy-efficiency, and manufacturability targets, leveraging Jabil's global footprint and quality systems.

Location:

This role can be based on-site at our St. Petersburg, FL Gandy Lab with relocation assistance to St. Pete as a possibility for the right person, or the team is open to someone remotely based anywhere in the U.S. with occasional travel to the St. Pete Gandy Lab. There will also be some occasional travel to customer sites (roughly 15-20% altogether), depending on business needs and projects.

What Will You Do?

System Architecture & Requirements

• 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

Controls, Connectivity & Interoperability

• 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.

Customer Engagement & Business Support

• 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.

Design Reviews & Cross-Functional Collaboration

• 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

Compliance, Codes & Standards

• 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

Thermal/Acoustics & System Analysis

• 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…
