Data Center Mechanical Engineer

Anthropic develops reliable, interpretable, and steerable AI systems. The Senior Data Center Mechanical Engineer will lead the design direction and technical oversight of mechanical systems for Anthropic’s U.S. data center portfolio, including cooling, chilled-water distribution, liquid cooling, plumbing, and fire protection. The role also oversees external engineering and development partners, prefabricated and modular delivery strategies, construction, and commissioning.

Responsibilities:

• Drive mechanical design concepts for data center cooling plants, chilled-water distribution, liquid cooling (direct-to-chip and CDUs), plumbing, and fire protection systems
• Review and direct design drawings, specifications, and construction documentation produced by external engineering firms, ensuring alignment with Anthropic’s Basis of Design and owner requirements
• Evaluate design submittals, shop drawings, and equipment selections; respond to RFIs with clear technical direction
• Identify design conflicts and drive resolution across mechanical, electrical, and controls disciplines
• Maintain and evolve Anthropic’s internal mechanical design standards and reference configurations
• Drive Anthropic’s prefabricated and modular mechanical strategy — modular cooling skids, prefabricated piping and pump assemblies, and design for offsite manufacture and onsite assembly — to accelerate deployment and reduce onsite labor
• Drive standardization of modular mechanical designs across sites while preserving flexibility for site-specific constraints and evolving hardware generations
• Serve as the primary mechanical engineering point of contact for external developers, design engineers, and construction partners across the U.S. portfolio
• Develop scopes of work, equipment specifications, and bid packages for mechanical infrastructure
• Perform technical due diligence on third-party and colocation facilities, evaluating mechanical designs against program requirements and redundancy targets
• Coordinate with equipment vendors and manufacturers on cooling system procurement, including chillers, CDUs, pumps, and piping assemblies, and partner with supply chain to mitigate lead-time and single-source risk
• Monitor mechanical system installation for compliance with design intent, applicable U.S. codes and standards, and industry best practice
• Conduct site visits to review progress, resolve field issues, and validate construction quality; travel to sites across the region as needed
• Support testing and commissioning of mechanical systems; analyze data and troubleshoot issues against design intent

Requirements:

• Have 10+ years of experience designing building mechanical systems for data centers or mission-critical facilities, across the project lifecycle from concept design through construction, commissioning, and handover
• Have deep familiarity with U.S. mechanical, plumbing, and fire codes and standards — including the International Mechanical Code (IMC), International Plumbing Code (IPC), International Energy Conservation Code (IECC), International Building Code (IBC), NFPA 13 (automatic sprinkler systems), ASME B31 piping codes, and applicable state and local amendments, alongside ASHRAE guidance (incl. TC 9.9)
• Have strong knowledge of chilled-water systems, air-cooled cooling plants, liquid cooling (direct-to-chip and CDUs), and redundant piping configurations
• Have hands-on experience with prefabricated and modular mechanical infrastructure — modular cooling skids, prefabricated piping assemblies, and design for offsite manufacture
• Have experience driving and reviewing mechanical design work produced by external engineering consultants, and are proficient reading and marking up construction drawings, P&IDs, and single-line diagrams
• Hold a bachelor's degree in Mechanical Engineering; a Professional Engineer (PE) license (or eligibility) is valued but not required
• Communicate clearly and can drive technical decisions across internal teams and external partners, and are results-oriented with a bias toward practical solutions
• Are able to travel up to ~30% to data center sites across the region
• Minimum education: Bachelor's degree or an equivalent combination of education, training, and/or experience
• Required field of study:A field relevant to the role as demonstrated through coursework, training, or professional experience
• Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position
• 15+ years of experience designing building mechanical systems for data centers or mission-critical facilities
• Direct project experience delivering data centers in multiple U.S. markets (e.g., Virginia, Ohio, Texas, Arizona, Oregon)
• Experience with thermal-hydraulic modeling software (AFT Fathom, Cadence 6SigmaET, ANSYS, or similar), CFD modeling, and energy analysis
• Familiarity with controls/BAS systems and sequences of operation for cooling plants
• Experience preparing SOWs, facility audits, and TCO analyses
• A track record building modular prefabricated products in mechanical or electrical areas of the data center, and driving designs toward offsite manufacturing
• Proficiency with Revit MEP or AutoCAD MEP
