Be proficient with Microsoft Word, Excel, Adobe Acrobat, Bluebeam, and related design/document management software.
Have experience preparing ERCES submittal packages, permit drawings, equipment data sheets, link budgets, battery calculations, RF predictive heat maps, riser diagrams, antenna/device layouts, and related design documentation.
Be able to read and interpret construction drawings, electrical drawings, architectural drawings, mechanical drawings, reflected ceiling plans, specifications, contracts, addenda, RFPs, and scope documents.
Possess good communication, analytical, organizational, and problem-solving skills.
Be able to communicate professionally with project managers, estimators, field technicians, commissioners, general contractors, engineers, consultants, clients, inspectors, plan checkers, and AHJs.
Be able to manage multiple design projects simultaneously, depending on project size, complexity, scope, deadlines, and permitting requirements.
This position requires visual acuity and listening ability.
Individuals must have the dexterity to operate office and field equipment, including computers, printers, copiers, scanners, telephones, plotters, RF test equipment, measuring tools, and other office or field equipment.
Individuals may be required to visit active construction sites, attend field meetings, conduct or observe radio surveys, access electrical rooms, telecommunications rooms, ERCES equipment rooms, riser rooms, mechanical rooms, parking structures, rooftops, and other building areas as needed.
Site visits may require the use of ladders, stairs, personal protective equipment, and access to areas with active construction operations.
Applicants must be currently authorized to work in the U.S. on a full-time basis without future employment sponsorship
