Overview

The Electrical Engineer II focused on the design, development, and support of both electrical hardware and embedded software for Culligan’s residential, retail, and commercial water treatment products. This individual will contribute to new product development and continuous improvement initiatives. Responsibilities

Design and analyze moderately complex analog and digital circuits, including regulated power supplies, sensor interfaces, and communication modules (e.g., Bluetooth, Wi-Fi). Select appropriate components based on system requirements, performance, and cost. Create schematic capture and full PCB layout using Altium. Build and test prototypes, conduct design validation, and support transition to production. Ensure hardware designs meet relevant safety, EMC/EMI, and regulatory standards (e.g., UL, CE, FCC). Develop embedded software for microcontroller-based systems, including system-level architecture, control logic, sensor data processing, and communication protocols ensuring modularity, scalability, and maintainability. Perform software integration, unit and regression testing to validate functionality and reliability. Troubleshoot firmware issues using tools like oscilloscopes, logic analyzers, and debuggers; optimize code for performance and resource efficiency. Generate and maintain electrical design documentation, BOMs, test reports, software requirements, design specifications, and test plans. Work closely with mechanical and manufacturing teams to ensure cohesive product development. Participate in all phases of the product development lifecycle—from concept and design through testing, release, and field support. Identify opportunities for design optimization, cost reduction, and performance enhancement. Support junior engineers and contribute to technical reviews and knowledge sharing. Perform other job responsibilities as needed. Requirements
