Your Work Shapes the World at Caterpillar Inc.

When you join Caterpillar, you're joining a global team who cares not just about the work we do – but also about each other. We are the makers, problem solvers, and future world builders who are creating stronger, more sustainable communities. We don't just talk about progress and innovation here – we make it happen, with our customers, where we work and live.

Together, we are building a better world, so we can all enjoy living in it.

Caterpillar’s Oil and Gas division provides superior products and service solutions to make our customers more efficient and lower total cost of ownership. Globally, we deliver engineered oilfield and drilling equipment repair and certification, mechanical and rotating equipment repairs and upgrades, rapid prototyping of spare parts, robust asset management, operation and maintenance and field engineering services. We offer a wide range of career opportunities across a variety of technical and business roles in engineering and service locations worldwide.

Join our team and help build engineering solutions that change the industry. When you join the Caterpillar Oil & Gas and Marine Division (COGMD), you join a global team that helps to power the global energy industry as well as provide power and propulsion on the water.

As a Marine Electrical Integration Engineer, you are responsible for the detailed configuration, electrical design, and systems integration of Cat Marine hybrid applications. You will execute the engineering work required to integrate propulsion engines and gensets with advanced power components, including electric motors, battery energy storage, and VFDs. This role focuses on the hands‑on delivery of integrated electrical packages, ensuring every custom solution is engineered for performance, regulatory approval, and seamless vessel installation.

• No sponsorship available
• This position is based in Houston, Texas or Mossville, Illinois
• This position does offer relocation
• This role requires working onsite 5 days a week

• Electrical System Design: Execute the selection, sizing, and configuration of electrical hardware for hybrid engine rooms. You will integrate the complete Cat Marine scope, focusing on AC/DC distribution, switch gear, battery management system (BMS) interfaces, and motor‑drive synchronization.
• Technical Documentation & Schematics: Develop and deliver high‑precision electrical technical packages. This includes creating detailed wiring schematics (AutoCAD Electrical), 3D electrical models (Creo), one‑line diagrams, and technical specifications for system installation.
• Regulatory Compliance Support: Prepare technical submittals and design documentation to ensure systems meet Classification Society rules (e.g., ABS, DNV, Lloyd's Register). You will ensure designs comply with USCG electrical requirements (e.g., 46 CFR Subchapter J) and manage technical correspondence with the Marine Safety Center (MSC).
• Project Engineering & Validation: Manage engineering activities for assigned projects from concept through validation. This includes hardware‑in‑the‑loop (HIL) testing, system‑level validation, and managing the electrical Bill of Materials (BOM) to ensure a fully functional customer solution.
• Techno‑Economic Analysis: Support the sales organization by performing value‑based benchmarking. You will analyze how specific electrical architecture affects a ship operator's CAPEX and OPEX, providing the technical data needed to recommend the most cost‑effective solution.
• Component Evaluation: Conduct "Make vs. Buy" analyses for electrical components and evaluate partner technologies (batteries, motors, inverters) to ensure they meet Caterpillar's rigorous marine‑ruggedized standards.

• Power Systems Engineering: Strong proficiency in AC/DC power distribution, power electronics, and the application of Variable Frequency Drives (VFDs) and Energy Storage Systems (ESS).
• Control Interfaces: Understanding of marine control systems and communication protocols (e.g., J1939, Modbus, Ethernet/IP) for…
