[Remote] Senior Mechanical Design Engineer

Note: The job is a remote job and is open to candidates in USA. Worldwide Mission Critical is seeking a Senior Mechanical Design Engineer to serve as the technical authority for mechanical systems design on large-scale data center projects. This role involves leading the full lifecycle of mechanical design, ensuring high quality and reliability of HVAC and cooling infrastructure.

Responsibilities

• You will serve as the senior technical lead for mechanical design across the full project lifecycle — from concept development and load modeling through detailed engineering, construction documentation, commissioning, and operational handover
• You will lead and oversee mechanical engineers and designers, establishing design standards, reviewing deliverables, and cultivating a high-performance team culture rooted in technical excellence and knowledge sharing
• You will coordinate closely with Development, Procurement, Construction, and Operations teams, as well as Engineers of Record (EoRs), consultants, and contractors to resolve complex design challenges and maintain cross-disciplinary alignment
• You will drive the research and integration of emerging technologies and advanced cooling strategies to enhance thermal management, energy performance, and system reliability across data center environments
• You will own the review and quality control of all mechanical design documentation including drawing sets, piping schematics, airflow diagrams, shop drawings, submittals, and commissioning reports
• You will ensure all mechanical systems comply with project requirements, internal standards, ASHRAE guidelines, and applicable local building codes
• You will lead proactive schedule and budget management for mechanical scope, including evaluating value engineering proposals, tracking key milestones, and holding EoR and contractor partners accountable to deliverables
• You will lead factory witness testing, site inspections, TAB coordination, and commissioning activities, confirming system readiness and integration with building management systems (BMS)
• You will collaborate with electrical, structural, and controls disciplines to ensure fully integrated and coordinated mechanical system designs
• You will drive project risk assessments by identifying mechanical-related risks and leading the development of mitigation strategies
• You will support the operations team during system handover, providing design intent context and ensuring maintainability and operability of mechanical systems post-turnover
• You will lead continuous improvement initiatives by incorporating lessons learned into updates to internal design tools, standards, templates, and delivery processes
• You will provide expert field support during construction, offering technical guidance and resolving installation challenges in coordination with the construction team

Skills

• Bachelor's degree in Mechanical Engineering with an emphasis on data center mechanical systems and mission-critical facilities
• Minimum 10 years' experience in the A/E industry with direct experience supporting hyperscale, colocation, or enterprise data center projects
• Revit BIM design experience required, including coordination of large-scale mechanical rooms, central plants, and equipment layouts
• Deep expertise in data center cooling system design including chilled water plants, cooling towers, air-based and liquid-based cooling strategies, rear-door heat exchangers, and direct-to-chip cooling
• Proven proficiency in thermal load calculations, airflow modeling, and energy analysis using tools such as HAP, TRACE, IES, CFD software, or equivalent platforms
• Extensive background in the design, construction, testing, and commissioning of mission-critical mechanical systems including chillers, pumps, AHUs, CRAH/CRAC units, and associated control systems
• Professional Engineering (PE) license required
• Demonstrated experience with redundancy strategies (N, N+1, 2N), maintainability, and fault-tolerant design for high-uptime data center environments
• Knowledge and experience in estimating, mechanical system design, operation, and commissioning of data center cooling plants, including integrated systems testing (IST) and development of MOPs and SOPs
• Strong familiarity with data center performance metrics including PUE and WUE, and proven strategies to optimize energy and water efficiency
• Comprehensive understanding of professional services from conceptual planning and site selection through detailed design, construction administration, and project close-out
• Strong written and verbal communication skills, organizational skills, and ability to lead and collaborate effectively across cross-functional teams
• Passion for improving workflows and driving continuous improvement across the mechanical discipline
• Proficient with Microsoft Productivity Suite products
