Job Description:
Job Title: Principal Mechanical Integration Engineer Job Family:
Mechanical Design Engineering Organization: Data Center
Infrastructure Team Location: Remote* OR Austin, TX *Requires up to
20% domestic and/or international travel (rare) How will you make
an impact? The Principal Mechanical Design Engineer (Data Center
Infrastructure) is a technical leader responsible for the
architecture, integration, and validation of advanced mechanical
systems supporting hyperscale data center environments. This role
requires deep expertise in liquid cooling technologies
(single-phase and two-phase), hydronic system design, structural
integration, and manufacturable rack-level infrastructure
solutions. This role is responsible for defining system performance
requirements, developing technical specifications, selection and
integration of critical components, and leading mechanical design
from concept through production release. Responsibilities include
wetted material selection, thermal and structural analysis,
fastening strategies, component layout, and design for
manufacturability. Partners cross-functionally to deliver reliable,
scalable, and cost-effective Data Center Infrastructure solutions
while advancing innovation in liquid cooling performance. What will
you do? - Lead the end-to-end mechanical design and engineering of
hyperscale Data Center Infrastructure (DCI) systems, including
liquid-cooled rack assemblies, CDUs, manifolds, enclosures,
structural frames, and associated hydronic piping systems. - Serve
as the technical authority for single-phase and two-phase liquid
cooling architectures, including primary and secondary loop design,
in-rack distribution, and system integration within hyperscale data
center environments. - Define and validate operational performance
requirements for liquid-cooled infrastructure, including pressure
ratings, hydrostatic limits, temperature ranges, flow rates and
uniformity, thermal expansion, durability, and serviceability. -
Design, analyze, and validate machined components, welded
fabrications, manifolds, and structural systems using advanced
engineering principles, including stress analysis, finite element
analysis (FEA), flow modeling, and structural load calculations to
ensure mechanical integrity and code compliance. - Lead wetted
material selection and compatibility analysis for liquid cooling
systems, including corrosion mitigation strategies, surface
treatments, cleanliness standards, and long-term durability
considerations. - Develop and review CAD models and complete
technical data packages using CREO, SolidWorks, or equivalent
tools; ensure design accuracy, manufacturability, and system-level
integration. - Author and approve technical specifications for
piping systems, rack-level cooling infrastructure, and hydronic
components, including installation guidelines, maintenance
procedures, testing requirements, and compliance with applicable
standards (ASME, ISO). - Establish and oversee validation protocols
including hydrostatic pressure testing, leak detection and
mitigation, flow resistance analysis, and corrosion verification to
ensure regulatory compliance and operational reliability. -
Evaluate customer design proposals and technical specifications to
assess feasibility, manufacturability, cost, and risk; provide
recommendations to optimize performance and total cost of
ownership. - Lead cross-functional design reviews with electrical,
thermal, manufacturing, quality, and supply chain teams to ensure
full system integration and compliance with product specifications
and applicable plumbing and hydronic codes. - Optimize rack
manifold design and manufacturing processes, including machining,
welding, surface finishing, connection interfaces, venting and
draining strategies, and flow path optimization to enhance
performance and manufacturability. - Drive continuous improvement
in manufacturing assembly methods and tooling in collaboration with
production teams and equipment vendors to improve quality,
scalability, and cost efficiency. - Lead root cause investigations
for complex mechanical failures identified during validation or
field deployment and implement corrective design improvements. -
Provide technical leadership in vendor qualification and management
for mechanical components and liquid cooling subsystems. - Identify
and mitigate technical risks impacting performance, schedule, or
cost, and contribute to R&D initiatives advancing liquid
cooling technologies and system innovation. MINIMUM QUALIFICATIONS
Education: - Bachelor’s degree in Mechanical Engineering, Systems
Engineering, or a related engineering discipline from an accredited
university. Experience: - 8 years' experience in mechanical design
and integration of mission-critical systems. - Proven track record
of successful system designs and implementations in a relevant
industry - Strong understanding of mechanical systems, integration
strategy, and system coordination - Familiarity with industry
standards and regulations related to Energy Storage Systems and
Data Center Infrastructure is preferred. - Excellent
problem-solving skills and attention to detail - Strong
communication and teamwork abilities PREFERRED QUALIFICATIONS -
