[Remote] Senior Engineer - Mechanical Design

Note: The job is a remote job and is open to candidates in USA. National Design Build Services (NDBS) is hiring a Senior Engineer to lead day-to-day mechanical design for data centers, mission-critical facilities and large industrial plants. The role includes developing calculations, equipment selections, drawings and models; coordinating across disciplines; and supervising and mentoring Design Engineers.

Responsibilities

• Adhering to NDBS Core Values
• Develop the mechanical design on assigned projects from the basis of design and P&IDs through milestone reviews and issued-for-construction (IFC) drawings
• Perform heat load, hydraulic, psychrometric and pipe sizing calculations, and select equipment such as chillers, air handlers, pumps and CDUs
• Prepare drawings, schedules, details and Revit models, and run Navisworks clash detection with other disciplines
• Coordinate day-to-day with plumbing, structural, electrical, civil and controls designers and sub-consultants, and bring open issues to the Lead Engineer
• Draft sequences of operation and support controls partners on PLC logic and Building Management Systems
• Track deliverables, engineering hours and review comments on assigned work, and report status to the Lead Engineer
• Design data center cooling systems, including chilled water plants, CRAH/CRAC units and fan walls, economizers and containment, applying the redundancy (N+1, 2N, concurrent maintainability) set in the basis of design
• Support liquid cooling design for high-density and AI workloads, including CDUs and technology cooling system (TCS) and facility water loops
• Design HVAC, process exhaust, compressed air, boiler and hot water systems, and size natural gas, process and utility piping for industrial facilities
• Prepare RFIs to close gaps in owner and process-equipment data
• Assign and schedule work for the Design Engineer, and set clear expectations for scope, quality and deadlines
• Check calculations, drawings and models
• Coach the Design Engineer on design methods, codes, software and NDBS standards, and give regular feedback on performance and development
• Identify where prefabricated pipe spools, skids and modules add value and design them for constructability and repeatability
• Confirm design concepts early so prefabricated piping can be released without rework
• Review and witness factory acceptance tests and support commissioning and integrated systems testing
• Take part in internal turnover meetings and help define scope, schedule and resources for assigned work
• Support preconstruction with design quantities and scope reviews for estimating
• Review trade-partner submittals and draft RFI responses for Lead Engineer approval
• Attend coordination meetings with owners, general contractors and trade partners, and use Procore and Autodesk Construction Cloud to manage documents
• Support quality control through site visits, field verification and punch lists

Skills

• Bachelor's degree in an engineering field
• Minimum 5+ years of HVAC/R design experience
• Or EIT with the ability to obtain a PE
• Hands-on experience with chilled water, hydronic and process piping design
• Working knowledge of ASHRAE, International Codes, NFPA, and ASME piping codes
• Experience guiding or mentoring junior engineers or designers
• Ability to work to deadlines while juggling several projects and changing priorities
• Self-motivated, with excellent time and task management skills
• Strong organization and communication skills, and the ability to work well in a team
• Mechanical preferred
• Data center, mission-critical or industrial experience preferred
• Professional Engineer (PE) license preferred
• Industrial process experience: process exhaust, compressed air, boilers and natural gas systems
• Liquid cooling and high-density (AI/HPC) data center experience
• Experience with design-build and design-assist delivery, and with Procore and Autodesk Construction Cloud
• Experience with prefabricated mechanical systems such as skids, pipe spools or utility racks
• Fluency in Revit MEP and AutoCAD
• Experience with Navisworks clash detection
• Experience with load software such as Trane TRACE or Carrier HAP

Benefits

• Remote work option in the United States
• Strong career development opportunities and clear pathways for career advancement
• Autonomy and flexibility
