Anthropic is building reliable, interpretable, and steerable AI systems. The company's Data Center team is responsible for delivering physical infrastructure to support frontier AI model training and serving at unprecedented scale and density.
As a Senior Data Center Mechanical Engineer, you will lead the design direction and technical oversight of building mechanical systems across Anthropic's rapidly expanding U.S. data center portfolio. This is a senior individual contributor role focused on driving and reviewing mechanical design from concept through detailed design and construction documentation, ensuring every facility meets Anthropic's standards for reliability, efficiency, and scalability.
Key responsibilities include:
**Design Direction & Review**: 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. 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.
**Prefabrication & Modular Delivery**: 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.
**External Partner & Vendor Coordination**: 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. Coordinate with equipment vendors and manufacturers on cooling system procurement.
**Construction & Commissioning**: 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. Support testing and commissioning of mechanical systems.
You bring 10+ years of experience designing building mechanical systems for data centers or mission-critical facilities, deep familiarity with U.S. mechanical, plumbing, and fire codes, and expertise in cooling architecture including direct-to-chip liquid cooling. Strong candidates have mission-critical mechanical design experience and the judgment to make sound trade-offs when the standard playbook doesn't apply.
