MEP Design Engineer - Houston, TX USA

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 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.
• 5+ 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.
