Sr Mechanical Designer

Architecture & Facilities Engineering (A&FE) is seeking a Senior Mechanical Designer to manage the inception, development, implementation, and sustainment of the full range of mechanical systems – HVAC, central plant, plumbing, and hydraulics/hydronics/compressed air – with independent, full ownership of above- and below-ground mechanical utilities and kitchen/food-and-beverage systems expertise.

The Senior Mechanical Designer leads design coordination across back-of-house and guest-visible (“show”) kitchen environments, applies judgment on evolving design-condition assumptions (e.g., observed humidity trends) beyond standard ASHRAE tables, prepares bid-level construction documents for review, signature, and sealing by a licensed Engineer of Record, and provides immediate support and response to reactionary projects.

You will report to the Manager or Senior Manager, Mechanical Engineering with DLR Architecture & Facilities Engineering. 

Responsibilities/You will

• Act as Owner’s Representative on projects from concept through construction at the Disneyland Resort, under the oversight of a licensed Engineer of Record. 

• Support the Engineer of Record, including preparing construction documents for review, signature, and sealing as needed; does not hold sealing/signing authority. 

• Act as a technical resource for colleagues with less mechanical engineering/design experience; motivate and oversee the work of others, including assigned interns. 

• Work independently, receiving minimal guidance from the Manager or Senior Manager, Mechanical Engineering. 

• Manage the design and development of contract documents for projects with in-house and outside resources to meet project scopes, schedules, and budgets. 

• Coordinate design activities and monitor field installations and demolition work that comply with specifications and code requirements. 

• Use and build experience to develop concept designs and Requests for Proposals (RFPs). 

• Provide immediate support and response to reactionary projects requiring urgent attention. 

• Independently own the full above- and below-ground mechanical utility scope – HVAC, central plant, plumbing, and hydraulics/hydronics/compressed air – with kitchen/food-and-beverage systems expertise, leading design coordination across back-of-house and guest-visible (“show”) kitchen environments. 

• Prepare drawings, engineering calculations, and specifications for review, signature, and sealing by a licensed Engineer of Record, ensuring all projects are designed to applicable local and state codes and statutes (California Mechanical Code, Title 24, ASHRAE standards). 

• Review shop drawing submittals and respond to vendor Requests for Information (RFIs) per Resort standards. 

• Conduct site visits to problem-solve issues and minimize schedule impacts. 

• Independently interface with consultants, contractors, and vendors, bringing a new perspective on existing solutions for complex, multi-system mechanical problems. 

• Partner with internal teams to develop, maintain, communicate, and enforce Walt Disney Company design guidelines, standards, master specifications, and details (including the Disney Master Design Specifications, DMGS). 

• Assist Project and Design Managers to resolve design compliance issues relating to project requirements; validate that item specifications are consistent with products installed before archiving manuals. 

• Build enhanced communications and expectations to successfully execute all projects. 

• Explain difficult or sensitive technical information to project stakeholders and work to build consensus across disciplines.
