[Hiring] Mechanical Engineer @AECOM

Role Description

AECOM is seeking to hire a highly skilled Junior Level Mechanical Engineer for the Data Center and Mission Critical team for our east region. This role will support the design, coordination, documentation, and delivery of mechanical systems for data center and other mission-critical facilities and will work under the guidance of senior engineers to ensure systems meet performance, reliability, energy efficiency, and operational requirements.

This position offers the flexibility of a remote work schedule and can be based from a variety of locations in the US where AECOM has an office. Although the position is primarily remote, periodic travel may be required for client meetings, key project milestones, onsite collaboration sessions, or other business-critical activities. Travel is expected to be occasional and scheduled in advance.

  • Support energy efficiency assessments and mechanical system performance evaluations.
  • Help review equipment selections and technical specifications for compliance with project requirements.
• Design Documentation and Deliverables
  • Prepare and update mechanical drawings, schematics, equipment schedules, and design documentation.
  • Assist with developing construction documents, design narratives, technical specifications, and equipment schedules.
  • Use engineering software and design tools, such as AutoCAD, Revit MEP, and relevant HVAC calculation programs.
  • Incorporate engineering markups and revisions into drawings and models.
• Multidisciplinary Coordination
  • Coordinate mechanical designs with electrical, structural, architectural, plumbing, fire protection, and controls teams.
  • Assist with identifying and resolving spatial conflicts and design clashes using BIM models and coordination tools such as Navisworks.
  • Participate in design coordination meetings and track outstanding technical issues.
  • Support coordination of mechanical equipment layouts, piping routes, ductwork, and equipment access requirements.
• Data Center and Mission-Critical Requirements
  • Develop an understanding of the reliability, availability, and redundancy requirements associated with mission-critical facilities.
  • Support designs that maintain appropriate temperature, humidity, and environmental conditions for IT equipment.
  • Assist with mechanical system layouts and configurations that support continuous operations and maintainability.
  • Understand the importance of equipment redundancy, system resilience, maintainability, and phased construction in operational data centers.
• Construction and Project Support
  • Assist with reviewing contractor submittals, equipment shop drawings, and requests for information (RFIs).
  • Support responses to construction-related technical questions under the supervision of senior engineers.
  • Participate in site visits, construction observations, equipment inspections, and commissioning activities as needed.
  • Help document field observations, design discrepancies, and corrective actions.
• Codes, Standards, and Quality
  • Apply applicable building codes, mechanical codes, energy codes, and project-specific design standards under senior engineering guidance.
  • Assist with quality checks of calculations, drawings, and specifications.
  • Maintain accurate engineering documentation and support compliance with client requirements and internal quality procedures.

Qualifications
