Control Development Engineer in Mundelein

Energy Jobline ZR; Mundelein (IL); On-site; USD 110,000 - 150,000; Full time

Job summary

Delta, a global power and automation company, seeks a real-time control engineer to own islanding, grid-forming and protection-coordinated tasks. You will develop and validate IEC 61131-3/Python apps for islanding, grid-forming and blackstart, and implement IEC 61850 GOOSE mappings with protection interfaces.

Responsibilities include HIL validation with RTDS/OPAL-RT, documenting SCADA interfaces, and ensuring sub-100 ms response in control sequences.

Qualifications

• BS/MS in Electrical / Power Engineering; 5+ years (Staff: 8+) in real-time microgrid, substation automation, or protection-and-control development.
• Hands-on experience with at least one commercial EMS platform.
• Strong IEC 61850 (GOOSE, MMS, SCL/SCD), DNP3, and Modbus TCP experience.
• Working knowledge of IEEE 1547-2018, IEEE 2030.7/8, UL 1741-SB, and NERC PRC standards.
• Grid-forming inverter controls, IEEE 2800 / FERC Order 2023 familiarity.
• Experience with BESS, PCS, and hybrid AC/DC microgrid architectures.
• Cybersecurity awareness for substation automation (IEC 62443, NERC CIP).

Responsibilities

• Develop and validate real-time control apps for islanding, grid-forming, blackstart, and protection-coordinated load shedding.
• Implement IEC 61850 GOOSE publish/subscribe maps and define protection-to-control interfaces.
• Design V/f and P/Q droop logic, grid-tied island transitions, and sub-100 ms resynchronization.
• Co-own the RT Unit Controller SCADA data interface, document tag lists, scan rates, and failover.
• Run HIL validation on RTDS/OPAL-RT, develop test cases and automation for IEEE 1547-2018 and UL 1741-SB.

Job description

Job Description

Who we are:

Delta, founded in 1971, is a global provider of power and thermal management solutions. Its mission statement, "To provide innovative, clean and energy-efficient solutions for a better tomorrow," focuses on addressing key environmental issues such as global climate change. As an energy-saving solutions provider with core competencies in power electronics and automation, Delta's business categories include Power Electronics, Mobility, Automation, and Infrastructure.

Role Summary

You will own the deterministic logic for GOOSE messaging, load shedding, protection interfacing, islanding, mode transitions, V/f dispatch, and blackstart sequences. You will co-develop with partners during the partner phase and progressively insource Delta-specific apps. Key Responsibilities

• Develop and validate Real-time control applications (IEC 61131-3 / Python automation) for islanding, grid-forming, blackstart, and protection-coordinated load shedding.
• Implement IEC 61850 GOOSE publish/subscribe maps; define the protection-to-control interface with relay engineers.
• Design V/f and P/Q droop logic, mode transitions (grid-tied island blackstart), and resynchronization sequences with sub-100 ms response.
• Co-own the RT Unit Controller SCADA data interface; document tag lists, scan rates, and failover behavior.
• Run HIL validation on RTDS / OPAL-RT — develop test cases, automated regression scripts, and certification evidence for IEEE 1547-2018 and UL 1741-SB.

Required Qualifications

• BS/MS in Electrical / Power Engineering; 5+ years (Staff: 8+) in real-time microgrid, substation automation, or protection-and-control development.
• Hands-on experience with at least one commercial EMS platform.
• Strong IEC 61850 (GOOSE, MMS, SCL/SCD), DNP3, and Modbus TCP experience.
• Working knowledge of IEEE 1547-2018, IEEE 2030.7/8, UL 1741-SB, and NERC PRC standards.
• Grid-forming inverter controls, IEEE 2800 / FERC Order 2023 (IBR) familiarity.
• Experience with BESS, PCS, and hybrid AC/DC microgrid architectures including SST-based DC grids.
• Cybersecurity awareness for substation automation (IEC 62443, NERC CIP-005/007).
