About the role

The System Design Microgrid Solution Engineer is responsible for architecting, modeling, and validating electrical system designs to ensure the performance, stability, and regulatory compliance of utility-scale and commercial/industrial microgrid and data center power systems. This role drives the analytical foundation for project development, detailed engineering, and grid interconnection by providing deep insight into system behavior across steady-state, dynamic, and transient operating conditions. The position serves as a technical bridge between system architecture, control design, and grid requirements—ensuring designs are technically sound, standards-compliant, and deployment-ready for mission-critical applications.

Responsibilities

• Architect and maintain accurate system-level electrical models for microgrids, data center power plants, and distributed energy systems.

• Execute grid interconnection, performance, and compliance studies to support regulatory, utility, and customer requirements.

• Assess and validate system behavior under normal, transient, fault, and degraded operating conditions.

• Provide analytical input to system architecture, control strategy, equipment sizing, and protection philosophy decisions.

• Ensure study methods, assumptions, and results are technically defensible, traceable, and aligned with project deliverables.

• Support internal design reviews and external stakeholder engagements (utilities, ISOs, consultants, customers).

Key Accountabilities

• Develop Electrical System Models Including Generation, BESS, inverter-based resources, and solid-state transformers (SST)

• Loads, transformers, protection devices, and switching equipment

• Utility grid representations and point-of-interconnection models

• Ensure Alignment Between Study Models And Control design assumptions and tuning parameters

• Equipment ratings, datasheets, and settings

• One-line diagrams, protection philosophies, and operating procedures

Qualifications

• Perform and support studies including:

  • Load flow and voltage regulation analysis
  • Short-circuit and fault duty analysis
  • Dynamic and transient stability studies
  • Frequency response and inertia analysis
  • Harmonics and power quality studies
  • Islanding, black-start, and ride-through performance
  • Arc flash hazard analysis

• Support grid interconnection requests and processes. Perform studies aligned with standards and grid codes such as:

  • IEEE 1547 / 1547.1
  • Utility-specific interconnection requirements
  • Relevant IEC or regional grid codes

• Prepare technical documentation and study reports for utility submission, internal design validation, and customer/third-party review.

• Strong fundamentals in power system analysis, electrical machines, inverter-based resources, and dynamic/steady-state system behavior.

• Hands-on experience with industry power system simulation tools.

• Ability to interpret electrical one-line diagrams, control and protection philosophies, and equipment datasheets.

• Solid understanding of utility-connected and islanded power system operating modes.

• Systems thinker—able to balance control performance, hardware limits, grid requirements, and operational constraints.

• Structured problem solver—approaches complex technical problems methodically and transparently.

• Techical communicator—can clearly explain system design concepts to non-specialist audiences, customers, and leadership.

• Collaborative mindset—works effectively across disciplines and organizational boundaries.

• Ownership & accountability—takes responsibility for technical outcomes from concept through deployment.

• Adaptability—comfortable working in evolving architectures and handling ambiguous requirements.

• Attention to detail—maintains rigor in documentation, testing, and validation.
