Harbinger Motors is an American commercial electric vehicle (EV) company transforming the medium-duty EV and hybrid market. As a High Voltage (HV) Systems Integration Engineer, you will own the critical layer between individual power hardware components (inverters, rectifiers, converters, battery packs) and complete, functional energy systems such as MW-scale generators, auxiliary power sources, electric trucks, and battery chargers.
Key Responsibilities:
• System Commissioning: Lead end-to-end system bring-up and commissioning at test and field pilot sites, including MW-scale generators, battery-based auxiliary power systems, inverters, and other high-power systems.
• Architecture Development: Develop clean-slate architectures for interfacing high-voltage systems with field-serviceable equipment, integrate protection equipment, and ensure compliance with stringent UL and automotive standards.
• Interface & Communication Coordination: Link high-voltage components with Supervisory Control and Data Acquisition (SCADA) and vehicle/grid networks using protocols such as CAN, Modbus TCP, I2C, optical links, and SPI.
• Test Automation & Scripting: Write Python or C/C++ scripts to automate bring-up procedures, sequence high-power runs, and log real-time performance data.
• Failure & Root-Cause Analysis: Diagnose and troubleshoot problems in the field and provide data feedback to firmware and hardware design teams.
• Cross-Functional Collaboration: Work directly with electrical hardware, systems, firmware, mechanical, and thermal engineers to ensure systems meet safety standards (IEEE, NERC, UL) and performance goals.
• Technical Documentation: Develop bring-up and integration manuals for use by customers and internal teams.
This is a high-level ownership role on a growing team spanning multiple business verticals. The position requires 50% travel within the US and internationally for troubleshooting and commissioning.
Requirements:
• 7+ years of experience in electrical systems integration and commissioning
• Advanced-level understanding of electrical engineering concepts with ability to think on your feet and propose solutions
• Ability to work with minimum requirements to develop solutions quickly and iterate
• Excellent problem-solving skills and ownership mindset
• BS/MS/PhD in Electrical Engineering, Applied Physics, or related field
• Proficiency in MATLAB, CATIA, and Capital
• Ability to travel 50% of the time both within the US and internationally
Preferred Qualifications:
• Experience with generator and battery-based high-power systems (MW scale)
• Experience with large-scale data-center deployments
• Proven track record of fast-paced commissioning and troubleshooting at customer sites
• Prior startup experience
