Requirements

: up to 10% About Submer Submer designs and delivers end-to-end AI datacenter infrastructure built around industry-leading liquid cooling. We help organizations scale AI beyond the limits of traditional datacenters by enabling higher density, greater efficiency and lower environmental impact – accelerating time-to-AI from first deployment to full production. What impact you will have We are seeking a specialized Senior MEP Design Engineer to lead the research, prototyping, and execution of modular, hyperscale data center units.

into efficient, scalable, and code-compliant modular packages. Your focus will be optimizing equipment layout in a modular data center (MDC container to survive physical transport, rigging, and rapid on-site deployment while reducing deployment timelines and cost.

What You’Ll Do

Modular Integration: Engineer and optimize physical layouts for server racks, cable routing, and containment while eliminating spatial conflicts using BIM. Ensure structural enclosures maintain integrity during transport, lifting, and field installation. Direct Liquid Cooling Architecture: Design secondary fluid networks inside the container, including Cooling Distribution Units (CDUs), manifolds, and dripless quick-disconnect lines.

Electrical System Design: Architect electrical paths capable of delivering 100 KW + per rack, detailing high-capacity busways, intelligent PDUs, and localized power protection. Create and audit single-line diagrams, schematic wiring, and cable schedules. , in-row cooling, hot/cold aisle containment, liquid cooling).

Use Computational Fluid Dynamics (CFD) to validate cooling performance under maximum thermal loads. Controls Telemetry: Architect monitoring and telemetry systems, including DCIM (Data Center Infrastructure Management) networks and BMS (Building Management Systems). Manufacturing Testing: Drive prototype development, create standard fabrication instructions, and conduct Factory Witness Testing (FWT) to ensure manufacturability.

, NFPA 70, UL, ASHRAE guidelines) What you will have BS or MS in Mechanical Engineering, Electrical Engineering, or a highly technical equivalent discipline. Experience: 8+ years in mission-critical data center design, with a strict emphasis on liquid cooling (Direct-to-Chip or Immersion) and hyperscale facilities. Fluid Dynamics Mastery: Deep knowledge of closed-loop fluid dynamics, structural piping design, materials compatibility, and anti-corrosion/filtration chemical treatments.

Software Toolset: Mastery of Autodesk Revit, CREO or SolidWorks, and specialized structural or piping software. , Revit], ensuring clash detection, spatial coordination, and seamless integration with architectural and structural designs. Proficiency in thermal-fluid systems design, mechanical packaging, and system-level integration.

Excellent communication and project leadership skills across cross-functional engineering disciplines.

Qualifications

Licensure: Active Professional Engineer (PE) status or Chartered Engineer (CEng) equivalent Hyperscale Credentials: Certified Mission Critical Professional (CMCP) or Uptime Institute Accredited Tier Designer (ATD). , NVIDIA DGX, AMD Instinct, or Intel Gaudi systems). Fluid loop expertise: Deep knowledge of ASHRAE Liquid Cooling Guidelines (W1 to W5 water temperature classifications).
