Small wages, high voltages, long hours of difficult technical work, safe career choice doubtful. Riches and Glory in case of success. ## JOB DESCRIPTION Join Fleetzero's Electrical, Hardware, & Embedded team and contribute to R&D and production of the next generation in maritime technology. We work in a highly iterative method, testing early and often, rather than a traditional linear or waterfall development program. In this team, you will develop power conversion and distribution systems and related circuitry for vessel propulsion in autonomous, electric, and hybrid vessels. You will integrate with marine, hardware, and firmware engineers and manage projects from conception through testing iterations, prototype manufacturing, and field testing. This is a hands-on role developing critical components for safety-critical applications in harsh environments. You will be expected to be comfortable taking independent initiative and working as a team with other highly motivated engineers. ## Responsibilities - Design ship power conversion systems, including switchboards and components, using bidirectional inverters, associated filtering, fusing, and circuit protection. - Serve as a subject matter expert for electrical power system integration activities. - Design and analyze vessel electrical & propulsion systems, ranging from clean slate design to system modifications - Select and integrate transformers, DC-DCs, control gears, sensors, enclosures, busbars, fuses, etc, in various marine applications - Integrate Fleetzero-designed systems with vessel legacy propulsion systems for testing - Develop one-line diagrams, schematics, wiring diagrams, load analyses, and other relevant work products necessary for R&D through sea trials - Participate in testing, troubleshooting, commissioning, and integration ## Qualifications - 5+ years of experience in electrical engineering, focusing on system-level design, development, and testing. - Degree in Electrical Engineering or equivalent experience. - Experience and competence in power generation and distribution systems. - Experience with filtering 3ø power from PWM devices (i.e., LCL filtering) - Proficiency in system testing, including development and execution of test procedures. - Excellent problem-solving skills with a detail-oriented mindset. - Ability to collaborate effectively within a multidisciplinary engineering team. - Ability to work in a collaborative, fast-paced environment Bonus Qualifications - Experience with the marine environment and/or marine equipment (Navy, Merchant Marine, Naval Architecture & Marine Engineering, etc.) - Experience with Marine Class Societies (ABS, DNV, LR, etc) - Experience with USCG, MIL STD, UL, and other regulatory bodies and standards All roles are expected to include intermittent or occasional travel as the business needs. The salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only. Actual salary offer may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations. Highly competitive equity grants are included in most full time offers and are considered part of Fleetzero's total compensation package.

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.
