Senior Electrical Design Engineer

Job Summary

The Senior Electrical Engineer will lead electrical analysis, design, controls integration and overall electrical performance for HVAC equipment, including air handlers, fan coils, blower coils and VAV platforms. This role supports new product development, sustaining engineering, prototyping, laboratory validation and manufacturing execution across air handling, fan coil and VAV platforms. The position is based onsite in Largo, FL.

• Define system‑level electrical architectures, perform load analyses and coordinate protective devices for HVAC equipment platforms.
• Design and review electrical schematics, wiring diagrams and harnesses, and develop panel, enclosure and junction layouts that support manufacturability, serviceability and thermal performance.
• Integrate motors, variable‑frequency drives (VFDs), electronically commutated (EC) motors, controllers, sensors, actuators and control interfaces across both line‑ and low‑voltage systems.
• Develop and maintain electrical engineering standards, parts libraries, specifications and design rules supporting configurable products and dynamic bill‑of‑material (BOM) generation.
• Interpret and apply applicable electrical safety and compliance requirements, including NEC, UL1995 and UL60335‑2‑40, ensuring designs meet agency requirements for wiring methods, protection, accessibility and markings.
• Create and maintain agency listing documentation, support certification testing and work with internal compliance teams and third‑party agencies to resolve non‑conformances and implement corrective actions.
• Support A2L refrigerant programs, including refrigerant detection system integration, alarm and control responses and sensor location coordination.
• Partner with the test laboratory to define and execute electrical test plans validating motors, drives, heaters, controllers and safety devices.
• Analyze test results, identify root causes and drive corrective actions.
• Collaborate with sourcing to deliver production‑ready electrical BOMs, qualify new suppliers and components, and support cost and obsolescence mitigation.
• Support manufacturing engineering with DFMA improvements to ensure successful transition from design to production.
• Provide electrical guidance to applications engineering, sales, service and field teams regarding product capabilities, installation constraints and troubleshooting.
• Lead and participate in continuous improvement initiatives to reduce design cycle time and increase engineering throughput.
• Mentor junior engineers and designers to ensure consistent application of engineering standards and best practices.

• Required:
  
  Bachelor’s degree or equivalent in Electrical or Controls Engineering.
• 5+ years electrical engineering experience in HVAC or a closely related product‑based manufacturing environment.
• Proficiency creating two‑dimensional electrical schematics using AutoCAD or similar tools.
• Experience working with electrical bills of material, component databases and engineering documentation systems.
• Preferred:
  Hands‑on experience supporting prototype builds and laboratory testing of motors, drives, heaters, controllers and safety devices.
• Familiarity with A2L refrigerant detection systems, wiring practices and control responses.
• Experience supporting configurable product platforms and dynamic BOM logic.
• 3D CAD experience with Solid Works.
• Working knowledge of NEC, UL1995 and UL60335‑2‑40 as applied to equipment wiring, protection devices and accessibility.
• Prior experience mentoring engineers or designers.
