Harbinger is building the next generation of medium-duty electric vehicles, and we're in one of the most exciting chapters of our company so far — evolving our brand, expanding into new verticals, and scaling how we show up in the market. We're looking for a Marketing Intern focused on Events to support Harbinger's growing presence at trade shows, ride-and-drives, dealer and fleet events, industry conferences, and other brand experiences. Working closely with the Event Marketing Manager and broader Marketing team, you'll help bring events to life from early planning through on-site execution and post-event follow-up.
This is a highly collaborative, hands-on role for someone who is an exceptionally strong communicator, highly organized, and comfortable coordinating across many moving pieces. You'll work with teams across Harbinger—including Sales, Engineering, Service, Operations, and Marketing—as well as outside vendors and partners to gather information, coordinate assets, track deliverables, and make sure the details come together.
You'll gain real-world experience executing B2B events for a fast-growing automotive technology company while contributing to programs that directly support Harbinger's brand, customer relationships, dealer network, and sales pipeline.
