About the company:

Fleetzero is a marine energy and robotics company focused on decarbonizing the global shipping industry through advanced battery technology and electric propulsion systems. Founded in 2021, the company develops the Leviathan Modular Energy Storage System, a marine battery platform engineered to deliver high energy density at costs competitive with fossil fuel alternatives. Their flagship marine battery container stores 3.8 MWh of energy in a footprint 25% the size of a standard shipping container, and the system is designed to scale from small support vessels to large ocean-going ships, including missions capable of crossing the Pacific Ocean on a single charge.

Fleetzero is building battery-electric ships and we need more hands on the marketing team this summer and fall.

This is a real-work internship. You will draft content, research, prep events, support campaigns, and handle whatever the team needs to ship that week. You will work directly with the VP of Marketing. The output will be real - not practice projects, not internal decks that never go anywhere.

You will leave with portfolio pieces that shipped.

What We're Looking For

• Currently pursuing a degree in Marketing, Communications, Journalism, Business, or a
related field.
• Strong writing skills, with a natural creative propensity.
• Familiarity with at least one of: social media management, content production, graphic
design, or marketing analytics.
• High agency: you figure things out, ask smart questions, and don't need to be managed.
• Interest in maritime, energy, defense, or deep tech. Curiosity about the industry goes a
long way.
• Ability to work on-site at our Houston facility.

Bonus Points

• Experience running or contributing to a campus organization's social media or
communications.
• Proficiency in Figma, Adobe Creative Suite, or video editing software.
• Previous internship or project experience in a startup, agency, or technical industry.
