SUBMER • Houston, TX

1d • Hybrid

About The Position

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. We are seeking a specialized Senior MEP Design Engineer to lead the research, prototyping, and execution of modular, hyperscale data center units. You will translate client and IT capacity requirements 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.

Requirements

• BS or MS in Mechanical Engineering, Electrical Engineering, or a highly technical equivalent discipline.
• 8+ years in mission-critical data center design, with a strict emphasis on liquid cooling (Direct-to-Chip or Immersion) and hyperscale facilities.
• Deep knowledge of closed-loop fluid dynamics, structural piping design, materials compatibility, and anti-corrosion/filtration chemical treatments.
• Mastery of Autodesk Revit, CREO or SolidWorks, and specialized structural or piping software.
• Develop, coordinate, and maintain intelligent 3D MEP models using [BIM Software, e.g., 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.

Nice To Haves

• Active Professional Engineer (PE) status or Chartered Engineer (CEng) equivalent
• Certified Mission Critical Professional (CMCP) or Uptime Institute Accredited Tier Designer (ATD).
• Direct history integrating server architectures from Tier 1 AI hardware providers (e.g., NVIDIA DGX, AMD Instinct, or Intel Gaudi systems).
• Deep knowledge of ASHRAE Liquid Cooling Guidelines (W1 to W5 water temperature classifications).
• Experience working inside a prefabricated modular assembly factory or automotive/aerospace packaging plant.

Responsibilities

• 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.
• Design secondary fluid networks inside the container, including Cooling Distribution Units (CDUs), manifolds, and dripless quick-disconnect lines.
• 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.
• Design precise HVAC and cooling systems (e.g., in-row cooling, hot/cold aisle containment, liquid cooling).
• Use Computational Fluid Dynamics (CFD) to validate cooling performance under maximum thermal loads.
• Architect monitoring and telemetry systems, including DCIM (Data Center Infrastructure Management) networks and BMS (Building Management Systems).
• Drive prototype development, create standard fabrication instructions, and conduct Factory Witness Testing (FWT) to ensure manufacturability.
• Ensure designs comply with mission-critical industry and regulatory standards (e.g., NFPA 70, UL, ASHRAE guidelines).

Benefits

• Attractive compensation package reflecting your expertise and experience.
• Medical Insurance Plan.
• 401K Employee volunteer contribution Plan.
• A great work environment characterized by friendliness, international diversity, flexibility, and a hybrid-friendly approach.
• You´ll be part of a fast-growing scale-up with a mission to make a positive impact, offering an exciting career evolution.
