About The Position

AECOM is hiring a junior-level Mechanical Engineer for its Data Center and Mission Critical team in the east region. The role supports the design, coordination, documentation, and delivery of mechanical systems for data centers and other mission-critical facilities. Under the guidance of senior engineers, the engineer helps ensure systems meet performance, reliability, energy-efficiency, and operational requirements. The position is primarily remote and may be based in a variety of U.S. locations where AECOM has an office. Occasional, advance-scheduled travel may be required for client meetings, project milestones, onsite collaboration, or other business-critical activities. Newly hired employees must attend an in-person Day 1 onboarding at an AECOM office. Relocation and U.S. employment authorization sponsorship are not available. AECOM intends to fill this current vacancy by January 27, 2027.

Familiarity with HVAC principles, thermodynamics, fluid mechanics, and heat transfer.
Exposure to AutoCAD, Revit MEP, BIM coordination, or HVAC calculation tools.
Strong analytical, problem-solving, communication, and organizational skills.
Interest in data center infrastructure, critical cooling systems, energy efficiency, and mission-critical engineering design.

Nice To Haves

Exposure to data center, healthcare, semiconductor, laboratory, industrial, or other mission-critical projects.
Experience with chilled water systems, redundant mechanical infrastructure, or commissioning.
Proficiency with engineering design software, BIM/CAD tools, and building-system applications such as Revit.
E.I.T. (Engineer in Training) professional designation.

Responsibilities

Assist in designing HVAC, cooling, ventilation, and mechanical utility systems for data centers and mission-critical facilities.
Support the design of chilled water systems, cooling towers, pumps, piping networks, air handling units, and CRAC or CRAH systems.
Assist with cooling strategies for high-density server environments, including liquid cooling and other advanced technologies as applicable.
Perform preliminary engineering calculations, equipment sizing, and load assessments under senior engineers’ direction.
Support mechanical load, heat rejection, airflow, and hydronic system calculations and analysis.
Assist with evaluating system redundancy and reliability, including N+1 and 2N configurations, and support energy-efficiency and system-performance assessments.
Help review equipment selections and technical specifications for compliance with project requirements.
Prepare and update mechanical drawings, schematics, equipment schedules, construction documents, design narratives, and technical specifications.
Use engineering software and design tools, including AutoCAD, Revit MEP, and relevant HVAC calculation programs; incorporate markups and revisions into drawings and models.
Coordinate mechanical designs with electrical, structural, architectural, plumbing, fire protection, and controls teams.
Help identify and resolve spatial conflicts and design clashes using BIM models and coordination tools such as Navisworks.
Participate in design coordination meetings, track technical issues, and support coordination of equipment layouts, piping routes, ductwork, and access requirements.
Support designs that meet mission-critical reliability, availability, redundancy, environmental, continuous-operations, and maintainability requirements.
Assist with reviewing contractor submittals, equipment shop drawings, and requests for information, and support construction-related technical responses under senior engineers’ supervision.
Participate in site visits, construction observations, equipment inspections, and commissioning activities as needed; document field observations, design discrepancies, and corrective actions.
Apply applicable building, mechanical, and energy codes and project 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.
