Marine Hybrid Controls & Software Integration...

As a Marine Hybrid Controls & Software Integration Engineer , you are responsible for the logic, architecture, and functional integration of Cat Marine hybrid systems. This role moves beyond physical wiring to focus on the "brains" of the vessel. You will support the design and implement the software and control strategies that govern how propulsion engines and gensets interact with electric motors, battery systems, and VFDs. Your goal is to deliver high-performance, automated power management solutions that are regulatory-compliant and optimized for complex vessel duty cycles., + Control Logic & Architecture: Design and configure the control architecture for hybrid power systems. You will develop functional sequences for power transitions (e.g., zero-emission mode to diesel-mechanical) and load-sharing logic

• Software Development & Configuration: Work with internal engineering teams to execute the programming and parameterization of Hybrid Control Units and Power Management Systems (PMS). You will focus on optimizing energy flows between battery systems, engines, generators and the bus

• Protocol Integration: Manage the seamless communication between diverse subsystems using J1939, Modbus TCP/RTU, and Ethernet/IP. You will ensure the Battery Management System (BMS), VFDs, and Engine Control Modules (ECMs) talk to each other without latency or error

• HIL & Physical Validation: Lead system level Hardware-in-the-Loop (HIL) testing and software-in-the-loop simulations. You will use these tools to validate control algorithms, fault-handling responses, and safety interlocks before any hardware arrives at the shipyard. Develop system level DFMEA's and validation test plans and execute system level testing

• Regulatory Software Compliance: Prepare documentation for software functional safety and cyber-resiliency to meet Classification Society rules (ABS, DNV, Lloyd's). You will ensure that software-based safety functions comply with USCG and International Marine requirements

• System Diagnostics & Commissioning: Develop software-based diagnostic tools and telemetry interfaces. You will support the commissioning of hybrid systems, perform real-time software tuning and troubleshoot during sea trials

• Communication & Networking: Advanced proficiency in marine data protocols (NMEA 2000, J1939, CANbus) and industrial networking (TCP/UDP, Managed Switches)

• Programming Tools: Experience with PLC programming (IEC 61131-3), MATLAB/Simulink for model-based design, or C++/Python for embedded system integration

• Power Electronics Interface: Technical knowledge of how software parameters affect VFD performance, motor torque curves, and battery discharge rates

• Safety Standards: Familiarity with Marine Classification Society and USCG functional safety standard

What You Will Have:

• 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

• Technical Excellence: Knowledge of a given technology and various application methods; ability to develop and provide solutions to significant technical challenges

• Product Design - MFG: Knowledge of processes, approaches, tools and techniques of product design; ability to convert customer and market requirements into product design

• Product Design and Development: Knowledge of product features; ability to design, build, and develop a new product, technology, or service from concept through to production

• Medical, dental, and vision benefits*

• Paid time off plan (Vacation, Holidays, Volunteer, etc.)*

• 401(k) savings plans*
