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. ## About Fleetzero ## Company Overview - **One-liner**: Fleetzero builds electric and hybrid propulsion systems for large ships, including modular marine battery systems and autonomy platforms, to decarbonize the maritime industry. - **Entity Type**: Private (Series A) - **Headquarters**: Houston, Texas, USA - **Founded**: 2021 - **Founders**: Steven Henderson (CEO) and Mike Carter (COO) ## Core Business - Primary industry: Maritime electrification, energy storage, and autonomous vessel technology. - Target customers: Commercial shipping operators, shipyards, and fleet owners (B2B, enterprise). - Mission or purpose: To decarbonize ocean freight by delivering safe, cost-effective battery-electric and hybrid solutions that eliminate the green premium. ## Products & Services - **[Leviathan Modular Energy Storage System](https://www.fleetzero.com/)**: Scalable marine battery system delivering up to 3.4 MWh in a compact container footprint. Designed for high energy density, safety, and rapid payback (typically <6 years). - **[Battery Barge](https://www.fleetzero.com/)**: A 55 MWh mobile charging platform that can charge multiple vessels simultaneously, expandable for larger operations. - **[Modular Hull Construction](https://www.fleetzero.com/)**: Pioneering modular shipbuilding to lower construction costs and increase output, enabled by electric propulsion. - **[Autonomy Platform](https://www.cbinsights.com/company/fleetzero)**: Integrated vessel navigation, control, and propulsion system for unmanned cargo operations, targeting underserved routes. ## Market Standing - **Valuation/Market Cap**: Not disclosed (private company). - **Key Metric**: Total Funding – $59.73M raised (Series A as of 2026). - **Notable Investors/Partners**: Maersk Growth, Breakthrough Energy, Obvious Ventures, Y Combinator (Winter 2022 batch). - **Growth Signals**: - Selected (2025) to build the world’s longest-range hybrid-electric vessel. - Series A completed in 2026 with prominent climate and maritime investors. - Launched commercial autonomy platform for shipping in 2026. - Team grew to ~40 employees (as of Y Combinator profile, likely larger now). ## Competitive Advantages - **Cost parity**: Leviathan batteries deliver double the power for half the price vs. other marine battery systems, enabling positive ROI within 2–6 years. - **End-to‑end integration**: Fleetzero’s team (US Navy veterans, mariners, engineers) provides white‑glove service from design through commissioning. - **Modularity**: Both energy storage and hull designs are modular, allowing rapid scaling and lower construction costs. - **Safety focus**: The company refuses to deploy any product they wouldn’t sail on themselves, emphasizing safety above all. ## Strategic Focus - Scaling modular battery production and modular hull construction to reduce shipbuilding costs. - Expanding autonomy platform to open new cargo routes and improve access to underserved markets. - Continuing to lower the cost of maritime electrification to make decarbonization economically viable for all vessel sizes. ## Why Work Here - **Mission‑driven**: Join a team tackling one of the hardest climate challenges – decarbonizing global shipping. The work involves high‑voltage systems, cutting‑edge battery technology, and autonomous robotics. - **Expert team**: Work alongside US Navy veterans, seafarers, and seasoned engineers in a hands‑on environment. The culture is described as demanding but rewarding: “The mission is difficult. The hours are long. The work demands skill, discipline, and resolve.” - **Location**: Based in Houston, TX. Likely on‑site due to manufacturing and testing. - **Growth trajectory**: Early employee at a well‑funded startup with major backers (Maersk, Breakthrough Energy) and clear commercial milestones already achieved. - **Notable perks**: Not explicitly listed, but the company emphasizes “white‑glove service with calloused hands” – a blend of high‑engineering and practical maritime experience. ## Sources 1.
