As a core part of Caterpillar’s Oil & Gas and Marine Division, our organization delivers world‑class engines, integrated power systems, life-cycle services, and digital technologies that help customers reduce total cost of ownership while improving uptime, efficiency, and performance. We offer a wide range of career opportunities across a variety of commercial, technical, and business roles worldwide. Join our team and help solve our customers’ toughest challenges.

About The Role:
As a Marine Mechanical Systems Integration Engineer, you will be responsible for the physical configuration, mechanical design, and system-level integration of Cat Marine mechanical propulsion and hybrid applications. You will execute the engineering work required to integrate traditional propulsion machinery—such as engines, gearboxes, transmissions and clutches.  Also in scope is the mechanical design and integration of advanced hybrid components at the system level for the Cat scope and the integration into the vessel.  This role focuses on the detailed delivery of integrated mechanical packages, ensuring every solution is engineered for high performance, and seamless vessel integration and installation.

Additional Information:

• This role is located in Houston, TX or Mossville, IL
• Travel: At least 30% domestic and international travel
• Relocation assistance provided
• This role requires 5 days onsite

What Will You Do:

• Vessel Performance Simulation & Modeling: Define and execute technical requirements for vessel performance modeling. You will define requirements and support the team developing simulations to evaluate performance optimization of engines and transmissions, hybrid duty cycles, fuel consumption, and energy flow, ensuring the mechanical and electrical system architecture meets the specific operational profile of the vessel.
• Total System Packaging: Execute the mechanical layout and structural integration of the complete Cat Marine scope. This includes the propulsion engines, drivelines, PTO/PTI electric motors, the mounting architecture and mechanical system interfaces in patrol craft, sportfishing vessels, pilot boats, workboats, and luxury yachts.
• Driveline & Power Transfer: Perform the detailed mechanical integration of marine propulsion engines and transmissions, couplings, hybrid drivelines, focusing on the interface between diesel engines and electric motors via transmissions, clutches, couplings and PTO/PTI gearboxes. 
• Regulatory Compliance: Prepare technical submittals and design documentation to ensure all mechanical and hybrid integrations meet Classification Society rules (e.g., ABS, DNV, Lloyd's Register). You will ensure designs comply with USCG requirements for machinery installations.
• Techno-Economic Analysis: Support the sales process by performing value-based benchmarking. You will analyze how specific mechanical configurations and simulated performance data affect a vessel operator's CAPEX and OPEX, providing the technical data needed to recommend the most efficient solution.
• Full-Lifecycle Engineering: Manage the day-to-day engineering tasks for assigned projects from concept through validation and production. Deliver high-precision 3D models (Creo), 2D drawings (AutoCAD), P&IDs, and integrated drawings that facilitate the physical installation of machinery and electrical distribution hardware.

Education & Experience Requirements

• Education: Bachelor’s degree in Mechanical Engineering, Marine Engineering, Naval Architecture, or a related technical discipline.
• Professional Expertise: Proven experience in the design and mechanical integration of marine propulsion engines, drivelines, gearboxes, transmissions and vessel performance analysis.

Top Candidates Will Also Have:

• Simulation Proficiency: Experience using simulation software (e.g., MATLAB/Simulink, Python, or proprietary vessel modeling tools) to predict hybrid system performance and fuel efficiency.
• Hybrid Component Integration: Hands-on experience with the physical packaging and cooling requirements of battery systems, motors, and inverters.
• Advanced Engineering Skills: Proficiency in rotational dynamics, torsional vibration, and structural mounting for heavy marine machinery.  Proficiency in the installation and application of marine diesel engines.
• Design Tools: High proficiency in Creo (Pro/E) for 3D modeling and AutoCAD for 2D schematics and P&IDs.
• Project Execution: Ability to manage a Bill of Materials (BOM) and execute project plans for complex, multi-disciplinary engine room solutions.

 

What You Will Have:

• Quality Management: Knowledge of quality management methods, tools, and techniques and ability to create and support an environment that meets the quality goals of the organization.
• Analytical Thinking: Knowledge of techniques and tools that promote effective analysis; ability to determine the root cause of organizational problems and create alternative solutions that resolve these problems.
• Effective Communications: Understanding of effective communication concepts, tools and techniques; ability to effectively transmit, receive, and accurately interpret ideas, information, and needs through the application of appropriate communication behaviors.
• Problem Solving: Knowledge of approaches, tools, techniques for recognizing, anticipating, and resolving organizational, operational or process problems; ability to apply knowledge of problem solving appropriately to diverse situations.
• Systems Thinking: Knowledge of the critical interdependencies among individual system elements that help and hinder performance; ability to plan and design solutions that synchronize resources to achieve business result
