Senior Controls Engineer

The Senior Controls Engineer is responsible for the architecture, design, and implementation of advanced control systems supporting high-power electrical equipment and integrated energy systems. This role spans hardware and software development, including control and power panel design, bill of materials (BOM) ownership, PLC/CODESYS programming, and Linux-based control environments.

This individual will serve in leadership and contribution in controls and automation, driving standardized, scalable solutions across product lines while ensuring alignment with SPOC’s Lift Up culture—promoting accountability, communication, and team-first execution.

Key Responsibilities

• Design and develop control systems for high-power applications, including system architecture, control strategies, and detailed design deliverables. Own and develop complete bill of materials (BOMs), I/O lists, wiring diagrams, and panel layouts to support production and field deployment. Ensure designs are manufacturable, serviceable, and aligned with company standards.
• Develop, program, and maintain control software across multiple platforms, including traditional PLC environments, CODESYS-based systems, and Linux-based control applications. Integrate control systems with inverters, drives, and other power electronics, ensuring proper operation, communication, and protection strategies.
• Configure and commission variable frequency drives and inverter systems, with strong preference for experience with Danfoss products or equivalent platforms. Develop parameter sets, communication interfaces, and control logic required for stable and efficient system operation.
• Collaborate cross-functionally with mechanical, electrical, and manufacturing teams to ensure seamless product development and execution. Actively participate in design reviews, providing technical input and identifying risks early in the design process.
• Support testing, validation, and commissioning activities, including prototype builds, factory acceptance testing (FAT), and field commissioning. Troubleshoot system issues across hardware and software domains, providing timely and effective resolution.
• Develop and maintain technical documentation, including control narratives, functional specifications, software documentation, and commissioning procedures. Ensure consistency and clarity across all deliverables.
• Mentor junior engineers and contribute to the development of engineering standards, templates, and best practices within the organization.

Required Qualifications

• Bachelor’s degree in electrical engineering, Controls Engineering, or related field.
• 7+ years of experience in industrial controls, automation, or power systems engineering.
• Demonstrated experience working with PLC platforms and CODESYS environments.
• Strong experience with Linux-based systems, including application development, scripting, and system integration.
• Direct experience designing and supporting high-power electrical systems, including integration with inverters or variable frequency drives.
• Proven ability to develop and manage BOMs, electrical schematics, and control panel designs.
• Strong troubleshooting skills across electrical systems, controls software, and integrated systems.

Preferred Qualifications

• Experience with Danfoss drives and inverter systems.
• Experience with industrial communications protocols (Modbus, CAN, Ethernet/IP, TCP/IP, etc.).
• Familiarity with power systems concepts including motor control, protection schemes, and energy systems.
• Experience supporting commissioning in field environments (marine, industrial, oil & gas, or similar).
• Exposure to embedded systems or edge-device software architecture is a plus.

Culture

• Strong communicator who actively engages across teams and disciplines to…
