À propos du poste

Summary

The Electrical Engineer designs, develops, integrates, documents, validates, and supports electrical and controls systems for mission-critical HVAC and data center cooling equipment. The position is responsible for translating product and customer requirements into safe, reliable, compliant, manufacturable, and serviceable electrical designs. The engineer works cross-functionally with mechanical engineering, controls/software engineering, applications engineering, manufacturing, quality, certification agencies, suppliers, and field service throughout the product lifecycle.

Essential Duties and Responsibilities

Provides electrical design of products/systems such as microprocessor controls and electrical power/control panels for HVAC equipment in accordance with engineering design standards.
Select and apply disconnects, circuit breakers, fuses, contactors, motor starters, variable-frequency drives, transformers, power supplies, relays, terminal blocks, and related protective devices.
Perform or document load calculations, conductor sizing, overcurrent-protection selection, control-transformer sizing, voltage-drop evaluation, power-supply loading, and component derating.
Determine or support equipment short-circuit current rating, including the effect of power-circuit components and branch protection.
Interpret and apply applicable product-safety, electrical, and equipment-construction requirements. Maintain the electrical design, approved critical-component information, and technical documentation needed to support third-party certification, factory inspections, product changes, and certification-agency reviews.
Creates engineering documentation related to the electrical design of HVAC equipment such as design spreadsheets, SAP bill of materials, electrical schematics, sequence of operations, and control panel layouts.
Provides engineering support and generates technical information for sales, marketing, applications engineering, production and field service groups.
Evaluates field installations and recommends design modifications to eliminate equipment or systems malfunctions.
Other duties as assigned.
