Microgrid Firmware Engineer - Grid-Ready Controls

Delta Electronics Americas; Morrisville (NC); On-site; USD 110,000 - 150,000; Full time

Job summary

Delta Electronics Americas, based in Morrisville, NC, is seeking an experienced control firmware engineer to implement and validate unit-level control firmware for power electronic assets in microgrid and utility-connected systems.

You will bridge equipment-level logic with grid-code requirements, develop startup/shutdown sequences, and support field commissioning and regulatory demonstrations.

Qualifications

• Bachelor’s degree in Electrical Engineering, Power Electronics, Controls, or related field; Master’s preferred.
• 3–7+ years of 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.
• Strong analytical and problem-solving capabilities.
• Excellent communication and documentation skills.
• Ability to work across global, cross-functional engineering teams.

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
