About this role

The Electrical Engineer III is a senior-level individual contributor responsible for leading the design, analysis, and support of electrical power systems and machine controls for drilling equipment. This role requires deep technical expertise in power distribution and control systems. The engineer owns major technical deliverables, guides junior engineers, and supports complex field issues.

Daily responsibilities include designing and analyzing LV/MV electrical power distribution systems such as switchgear, MCCs, transformers, OCPDs, and VFDs. Develop control hardware architecture for top drives, drawworks, mud pumps, and hoisting systems. Create electrical schematics, one-line diagrams, panel layouts, and wiring diagrams.

Coordinate with mechanical and controls engineers for integrated system design. Specify PLC, PAC, HMI/SCADA hardware and software from Beckhoff, Allen-Bradley, or Siemens. Perform load calculations, short-circuit studies, and protection coordination while ensuring compliance with NFPA, OSHA, NEC, and hazardous location standards.

Serve as technical lead for projects, conducting design reviews and mentoring junior engineers. Support FAT/SAT, commissioning, troubleshooting, and root cause analysis remotely or onsite. Collaborate with field service teams to improve operational excellence and reliability.
