Mechanical Design Engineer - Modular Solutions

Maverick Power • McKinney, TX

1d • Hybrid

About The Position

The Mechanical Design Engineer supports the specification, design, and integration of modular power solutions including E-Houses (modular electrical buildings), Power Distribution Centers (PDCs), and Medium Voltage/Low Voltage skids for mission-critical applications. In this role you will work alongside senior engineers to develop mechanical layouts, HVAC/ventilation concepts, equipment integration details, and manufacturing-ready documentation. You will be exposed to complete modular electrical-room systems that may include switchboards, ATS, UPS, battery rooms, HVAC, fire detection/suppression interfaces, and lithium-ion battery-related mechanical features.

Requirements

• B.S. in Mechanical Engineering (or related engineering discipline).
• Minimum of 2 years of mechanical design experience (internships/co-ops in industrial equipment, modular buildings, HVAC, or fabrication are highly valued).
• Working knowledge of basic engineering fundamentals (heat transfer, airflow, mechanical layouts, materials).
• Ability to produce clear 3D CAD drawings using SolidWorks.

Nice To Haves

• Exposure to modular E-Houses, electrical rooms, data center power modules, or skid-mounted industrial equipment.
• Basic familiarity with HVAC equipment selection concepts and equipment-room environmental control.
• Coursework or project exposure related to fire protection, life safety systems, or building codes.
• Experience reading equipment submittals and coordinating vendor data into drawings.
• EIT (Engineer-in-Training) credential or intent to pursue.

Responsibilities

• Create and update 2D/3D mechanical layouts for E-Houses and skid-mounted modules (equipment placement, access clearances, openings, penetrations).
• Coordinate mechanical interfaces with electrical equipment (switchboards, transformers, UPS, batteries, cable trays, conduit entry, grounding interfaces).
• Assist with heat load estimates and HVAC sizing support (collect equipment heat loads, document assumptions, support calculations).
• Lay out HVAC equipment, ducting/air distribution components, louvers, and ventilation paths to meet temperature and air quality requirements.
• Support mechanical documentation packages including general arrangement drawings, installation details, and bill-of-material inputs.
• Participate in design reviews to ensure maintainability, safe access/egress, and mechanical-code considerations are addressed.
• Respond to internal shop questions (RFIs) and update drawings as designs evolve through fabrication.
• Support factory acceptance testing (FAT) preparation (checklists, walkdowns) and occasional site activities under supervision.

Benefits

• Competitive Salary + Bonus Potential!
• Paid Time Off, 401K Matching, Medical, Dental, and Vision Benefits!
• High-growth organization with advancement opportunities!
• Diverse, Collaborative, & Fun Work Environment!
