OptiCool is positioned at the intersection of advanced thermal management, data center infrastructure, and liquid cooling technology. This role provides an opportunity to work on technically complex projects supporting the rapidly evolving data center industry while collaborating with applications, sales and manufacturing.

Join our collaborative engineering team as a Controls Engineer, where you will play a key role in the design and development of control systems for innovative cooling systems. From concept to post-sale support, you will contribute to the design, programming, documentation, and continuous improvement of products and components. You will also provide cross-functional support and be a key contributor to Opticool’s quality-first mantra.

ESSENTIAL DUTIES & RESPONSIBILITIES

• Design and develop new products and electrical components in a hands-on collaborative environment, ensuring alignment with project goals and technical requirements.
• Create and maintain accurate and detailed electrical schematics, wiring diagrams, and Bills of Materials (BOMs).
• Develop and implement control software for both R&D and commercialized products, ensuring functionality, safety, and regulatory compliance.
• Collaborate with project managers, mechanical engineers, software engineers to create project requirements and specifications
• Develop advanced PID, fault tolerant, redundant, and self-learning control systems.
• Develop detailed control narratives, process shutdown keys, process flow charts and interface control documentation to provide a comprehensive overview of the system functionality and interactions.

• Conduct thorough testing and validation of PLC systems to ensure reliability and performance.
• Maintain the controls hardware and software library to support all phases of the product lifecycle — from R&D through obsolescence.
• Enhance existing product designs to improve performance, reliability, serviceability, and manufacturability.
