Real-Time Microgrid Firmware Engineer

Delta Electronics Americas; Morrisville (NC); On-site; USD 120,000 - 180,000; Full time

Job summary

Delta Electronics Americas is seeking a senior engineer to own the design and in-house development of real-time control software for the Microgrid Controller (MGC). You will coordinate droop/grid-forming/dispatch logic across PCS, BESS, PV and genset assets using deterministic, bounded 1 ms loop timing.

Responsibilities include protecting coordination, control-tuning of power-electronics loops, deterministic comms (IEC 61850, Modbus, DNP3, PTP), HIL validation, and supporting certification

Qualifications

• B.S. or M.S. in Electrical Engineering, Power Electronics, Controls, or Computer Engineering (or equivalent).
• Strong grasp of power-electronics control and inverter dynamics.
• RTOS-based real-time embedded software in C/C++ with bounded WCET and deterministic scheduling.
• Experience with industry controllers/IEDs and power-system protocols (IEC 61850, Modbus, DNP3, PTP).
• Model-based design and HIL (MATLAB/Simulink, Typhoon HIL/OPAL-RT/RTDS) and Python test automation.
• Ability to read SLDs, protection settings, and write clear specs and test plans.

Responsibilities

• Develop the MGC real-time control application on a deterministic RTOS/RT-Linux target.
• Implement secondary control and protection coordination with tight timing budgets.
• Design and tune control loops for PCS/BESS interfacing and grid-forming resources.
• Configure and program industry controllers and middleware with IEC 61850 GOOSE/MMS/SV.
• Verify functions on HIL platforms (Typhoon HIL, OPAL-RT, RTDS) for grid-tied and islanded modes.
• Support certification and provide release evidence with design/test documentation.
