Mechanical Engineer – Data Centers

This is a full-time exempt (40+ hours/week), hybrid role located in Austin, TX; San Francisco, CA; New York, NY; or Seattle, WA.

Summary

We are seeking a Mechanical Engineer to support the design and deployment of next-generation, AI-optimized data center infrastructure. This role will be responsible for the end-to-end development of mechanical systems supporting high-density computing environments, from concept development and analytical modeling through construction and deployment.

The successful candidate will contribute to the creation of scalable, modular design standards that enable rapid deployment of mission-critical facilities globally. Working closely with internal stakeholders and external engineering partners, this role will help drive innovative cooling solutions, optimize facility performance, and support the continued evolution of advanced AI infrastructure.

Key Responsibilities

• Lead the design and development of mechanical systems for high-density, mission-critical data center facilities
• Develop and maintain modular mechanical design templates to support standardized and repeatable facility deployments
• Support mechanical engineering efforts from initial concept development through detailed design, construction, commissioning, and project completion
• Serve as a technical liaison between internal teams and external consultants, contractors, and engineering partners
• Ensure mechanical infrastructure integrates effectively with high-density cooling and electrical systems
• Perform engineering analysis and evaluate system performance to support design decisions and capacity planning
• Utilize Computational Fluid Dynamics (CFD) modeling to evaluate thermal performance and optimize cooling system effectiveness
• Develop innovative, scalable solutions that balance technical requirements, deployment speed, and supply chain considerations
• Review engineering deliverables and ensure compliance with project standards, performance requirements, and design objectives
• Support continuous improvement of mechanical design standards, specifications, and best practices
• Collaborate with multidisciplinary teams including electrical, structural, architectural, and operations personnel
• Manage technical relationships with external consultants and hold project partners accountable for quality and performance expectations

Our Ideal Candidate

• Bachelor’s degree in Mechanical Engineering
• 5–8 years of experience designing mechanical systems for data centers, mission-critical facilities, or large-scale industrial infrastructure
• Experience supporting the design and deployment of cooling systems for high-density computing environments
• Strong understanding of:
  • Chilled water systems
  • Heat rejection systems
  • Data center cooling architectures
  • Mechanical infrastructure supporting mission-critical operations
• Demonstrated experience with high-density cooling technologies, including:
  • Liquid-to-chip cooling
  • Immersion cooling systems
• Proficiency with Revit and Building Information Modeling (BIM) platforms
• Experience performing CFD modeling and thermal performance analysis
• Strong analytical and problem-solving skills
• Ability to manage multiple stakeholders and external engineering partners
• Strong communication skills and ability to work effectively in a fast-paced project environment

Preferred Qualifications

• Professional Engineer (PE) license
• Experience supporting hyperscale data center developments
• Familiarity with modular or prefabricated infrastructure deployments
• Experience developing engineering standards, templates, and repeatable design methodologies
• Knowledge of capacity planning and infrastructure scaling strategies
• Experience coordinating multidisciplinary engineering efforts across large project portfolios
• Familiarity with AI-focused, high-performance computing environments

Compensation & Benefits

• The pay for this W-2 position ranges from $96.15 – $120.19 per hour
• Medical Coverage: Two United Healthcare plans (PPO and HDHP with HSA), with employer contributions toward premiums; coverage begins the 1st of the month after 60 days of employment
• Dental & Vision: United Healthcare dental with 100% preventive care coverage and vision benefits for exams, frames, lenses, or contacts
• Wellbeing Support: Employee Assistance Program (EAP) offering confidential counseling plus additional wellness and care navigation resources
• Retirement & Savings: 401(k) eligible after 30 days with automatic 6% enrollment (opt-out available), 1% annual increases up to 10%, plus HSA with up to $480 employer contribution
• Voluntary Benefits: Employee-paid accident insurance and critical illness coverage for major health events
