Lead Microgrid Control Firmware Engineer

Delta Corp; Raleigh (NC); On-site; USD 120,000 - 160,000; Full time

Job summary

Delta Electronics Americas is seeking an experienced control firmware engineer to develop and validate unit-level control firmware for PCS, BESS, generators, and related systems. You will bridge equipment-level control logic with grid-code requirements across multiple assets, ensuring safe and compliant operation in diverse conditions.

You will collaborate across global engineering teams, implement startup/shutdown sequences, and tune grid-code functions including voltage and frequency control,

Qualifications

• Bachelor's degree in Electrical Engineering, Power Electronics, Controls, or related field.
• 3–7+ years of experience in control firmware implementation for PCS, inverters, or unit controllers.
• Strong understanding of inverter-based resource behavior and utility grid codes.
• Experience with PLCs, embedded controllers, or real-time control platforms.
• Familiarity with PSCAD or equivalent dynamic simulation tools.
• Strong debugging, system integration, and cross-functional collaboration skills.
• Professional working proficiency in English; additional languages are a plus.

Responsibilities

• Implement unit-level control logic for PCS, BESS, generators, SSTs, and balance-of-plant equipment.
• Develop startup, shutdown, fault handling, and recovery sequences with deterministic behavior.
• Implement grid-code required functions including voltage control, frequency response, LVRT/HVRT, and protection coordination.
• Develop and tune GFL and GFM control modes including active/reactive power control and ramp-rate limits.
• Implement local safety limits, interlocks, fallback logic, and protective functions.
• Ensure proper prioritization and coordination of commands between unit controllers, real-time controllers, and EMS.
• Validate control firmware through simulation, SIL, HIL, factory testing, and field commissioning support.
• Support certification, type testing, and utility or regulatory compliance demonstrations.
• Troubleshoot field issues and support commissioning activities.
• Document control logic, state machines, configuration parameters, and known limitation
