A typical day

A typical day could involve reviewing power system designs for a data center project, coordinating with utilities on interconnection, and working with internal teams on asset development. You might also support construction or operations teams to resolve power system issues. Exact routines depend on the project phase, so ask the hiring manager how the team is structured and what a typical week looks like.
