  • Communications and channel requirements for protection schemes

Support commissioning and field energization by:

  • Reviewing and commenting on relay and functional test plans
  • Responding to RFIs and field questions related to protection and control
  • Assisting with resolution of protection issues during construction and startup

This role offers a hybrid work arrangement, with the expectation of spending three days a week in the office, giving you the flexibility to work remotely for two days.
