Job description

GILLIG Engineering is responsible for the development, customization, and configuration of GILLIG’s clean technology heavy-duty transit buses. We are committed to developing the most reliable buses that connect communities, eliminate congestion, and contribute to a greener environment. Our engineers are engaged in designing, analyzing, testing, launching, and problem-solving across a wide range of technical areas.

GILLIG's Colorado Technical Center (CTC) is an engineering hub dedicated to advancing innovative technologies for GILLIG products. CTC Electrical Engineering Systems performs research and development on communication, low voltage, and high voltage architecture for GILLIG’s future products. Located in Loveland, Colorado, the CTC division plays a pivotal role in pioneering advancements in electric transportation." The CTC was created in early 2024 and is focused on developing the next generation ZEV powertrains and Advanced Engineering projects for the broader GILLIG enterprise.

Electrical & Electronic (E/E) Systems Engineering is responsible for designing, developing, and optimizing E/E systems and components including low & high voltage power distribution, CAN bus network topology & variation, powertrain/body component electrical system architecture and integration to ensure proper functionality, safety, durability, and performance. They collaborate with cross-functional teams to meet regulatory standards, trouble-shoot issues, and ensure cost-effective and efficient designs tailored to the needs of heavy-duty transit buses.

ABOUT THE ROLE

We are looking for a Senior Electrical Engineer who will be responsible for the overall design, development, and integration of our electrical systems for all future vehicles. You will have direct influence on vehicle electrical systems from concept through to manufacturing launch to field support.You will be part of the team that develops the industry’s best-in-class zero emission bus. You will focus on component selection, harness design, circuit protection and overall power distribution architecture. Assignments are broad in scope and highly complex that require outstanding creativity, superior initiative, good judgement, and leadership skills combined with the willingness to do hands-on engineering.

This is a hands-on, on-site role at our Loveland, CO facility (Colorado Technology Center) and reports to the E/E Systems Engineering Manager.

TECHNICAL FOCUS

Power and Signal Distribution

You will apply your skills & experience to provide highly customized, vehicle-based power & signal distribution systems through definition and/or selection of harnesses, devices, fusing, and connectors of appropriate size. Additional consideration for routing and environmental conditions will also play a major factor as the GILLIG Transit Bus is both a heavy-duty industrial and automotive product. Experience with low voltage (12/24VDC) and high voltage (600VDC) is required. Experience in electrical harness manufacturingand/or industrial/automotive control systems a plus.

IN THIS ROLE YOU WILL

• Design physical and logical schematics to show all electrical connections between different E/E components
• Size and select power distribution components and harness components
• Design and release harness documentation from prototype to production intent vehicles
• Create high/low voltage bus design, requirements, verification plans, and standards
• Maintain electrical profiles of components that are integrated into the E/E architecture then track and report on key performance indicators (KPIs) of the E/E architecture
• Perform safety and failure analysis of the E/E design
• Create bus level simulations of the vehicle to analyze electrical transients such as active and passive discharge, pre-charge, short circuits, etc.
• Perform the integration of E/E components that need to be connected to the vehicle’s E/E architecture
• Lead Root Cause Analysis (RCA) efforts and advise stakeholders on technical issues that could affect product design and delay deliverables
• Develop and implement scripts to perform consistency checks and verifications on design files and vehicle logs
• Collaborate with controls engineers to facilitate proper control of E/E components
• Develop troubleshooting guidelines in coordination with Service Engineers for fielded vehicles
• Mentor and provide technical direction for junior engineers
