Delta Electronics Americas—EEO

Job summary

Delta Electronics Americas is seeking an experienced control firmware engineer for power-electronics assets including microgrids and utility-connected systems. You will implement, tune, and validate unit-level and grid-code compliant firmware for PCS, BESS, generators, and related equipment.

The role involves collaborating across global engineering teams, debugging and validating firmware in real-time environments, and ensuring safe, deterministic operation under all conditions.

Qualifications

• Bachelor’s degree in Electrical Engineering or related field; Master’s preferred.
• 3–7+ years of control firmware experience for PCS/inverters/unit controllers.
• Strong understanding of inverter-based resource behavior and grid codes.
• Experience with PLCs, embedded controllers, or real-time control platforms.
• Familiarity with PSCAD or equivalent tools.

Responsibilities

• Implement unit-level control logic for PCS, BESS, generators, 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 limitations.
