Tiffin Motorhomes Inc.
Overview
The
Electrical Design Engineer
is responsible for designing, developing, testing, and implementing electrical systems, harnesses, and components that meet both functional and safety requirements for motorhome or vehicle production. This role involves collaboration across engineering, production, quality, and service departments to ensure that all electrical systems deliver reliability, serviceability, and customer satisfaction. Core Responsibilities
1. System Design & Development
Design and document
12V DC and 120V AC systems
for motorhomes, including power distribution, lighting, controls, and appliance circuits. Develop
schematics, wiring diagrams, and harness drawings
using CAD software (AutoCAD Electrical, SolidWorks Electrical, or similar). Design systems integrating
inverters, converters, battery management, solar charging, and generator interfaces. Specify electrical components (wiring, connectors, breakers, fuses, relays, switches, etc.) and ensure compatibility with manufacturing and service standards. Collaborate with mechanical and structural engineers to ensure electrical routing, mounting, and clearance compliance. 2. Prototyping & Testing
Build and test prototype harnesses and assemblies for new models or system upgrades. Conduct functional and safety testing, including
load testing, insulation resistance, polarity, and fault detection. Diagnose and troubleshoot electrical issues during pilot builds and production launches. Work with suppliers and internal teams to validate new technologies (e.g., lithium batteries, multiplex systems, smart controls). 3. Documentation & Standards
Create and maintain
BOMs (Bills of Materials) , harness routings, and revision-controlled schematics. Ensure all documentation complies with
RVIA ,
NFPA 1192 ,
SAE , and
UL
standards. Support production and service teams with up-to-date prints, troubleshooting guides, and installation procedures. Participate in
Engineering Change Orders (ECOs)
and manage drawing updates through PLM systems. 4. Cross-Functional Collaboration
Work closely with
production engineers ,
assembly technicians , and
quality teams
to ensure manufacturability and serviceability of electrical systems. Coordinate with
purchasing and suppliers
to source cost-effective, high-quality components. Partner with
controls/software teams
on smart features, multiplex wiring, or embedded control systems. Support
customer service
and
warranty
in diagnosing field issues and developing long-term design fixes. 5. Continuous Improvement
Analyze production and field data to identify recurring electrical failures and develop permanent countermeasures. Lead initiatives to improve efficiency, reduce wiring complexity, and improve electrical reliability. Implement lean engineering principles to streamline documentation and design processes. Required Skills & Competencies
Strong knowledge
of DC/AC power systems, load balancing, and circuit protection. Proficiency
in CAD and electrical schematic software (AutoCAD Electrical, SolidWorks Electrical, or EPLAN). Hands-on experience
with harness design, routing, and termination. Familiarity
with RV, automotive, or heavy-equipment wiring standards. Ability to read and interpret
mechanical drawings, blueprints, and system layouts. Analytical and troubleshooting
skills for diagnosing electrical and control issues. Effective communication
for cross-departmental collaboration and supplier coordination. Preferred Qualifications
Education:
Bachelor’s degree in Electrical Engineering, Mechatronics, or related field (Associate + experience acceptable). Experience:
2–5+ years in electrical system design for vehicles, RVs, or similar. Software:
AutoCAD Electrical, SolidWorks Electrical, EPLAN, or equivalent. Knowledge of:
Multiplex systems (Spyder, Firefly, KIB, etc.), lithium battery integration, inverter/charger systems, and solar power design. Certifications:
FE/EIT, RVIA certification, or UL familiarity a plus. Key Performance Indicators (KPIs)
On-time completion of design deliverables and drawing releases. Reduction of field electrical defects or warranty claims. Compliance with industry electrical codes and safety standards. Improved manufacturability and assembly time of electrical systems. Documentation accuracy and revision control integrity. Work Environment
Primarily office-based with regular shop-floor interaction for prototype and production builds. Occasional travel to suppliers, test facilities, or trade shows. Must be able to perform light hands-on electrical assembly and testing when required.
