Responsibilities

Perform complex HVAC engineering, design, analysis, and technical tasks using current technology, standards, templates, and cataloged products.
Develop technical solutions to complex problems, including in energy conservation and sustainability.
Collaborate with team members to develop design criteria and system requirements, and prepare conceptual and preliminary design documents.
Complete calculations for sizing and selecting equipment for large-scale facilities.
Participate in developing airflow schematics, duct and instrumentation diagrams, and general equipment arrangements.
Design and engineer building HVAC, fire alarm, fire suppression, gas detection, and plumbing systems in accordance with applicable codes and standards.
Survey existing facilities to establish their conditions.
Evaluate the cost-effectiveness of design alternatives and recommend alternatives for implementation.
Develop technical specifications, plans, elevations, sections, and details.
Perform engineering calculations and verify compliance with applicable codes and engineering standards and practices.
Coordinate with other in-house engineering disciplines as needed.
Conduct site visits, condition assessments, and construction inspections to identify latent defects, anticipate potential system failures, and verify installations against design specifications.
Gather and correlate basic engineering data using established procedures, perform engineering assignments involving calculations and simple tests, and identify discrepancies in results.
Propose approaches to new problems by adapting standard procedures or methods from previous assignments.
Complete work within agreed budgets and schedules with little supervision, independently performing the tasks needed to complete primary design elements.
