Job Description

What To Expect
Tesla is seeking a highly experienced Senior Electrical Engineer to lead the design, interconnection, and optimization of high-voltage electrical systems for large-scale industrial loads, including manufacturing facilities, data centers, and energy storage projects. The ideal candidate will have deep expertise in interconnecting large loads with utility providers, designing switchyards and substations at ultra-high voltages (up to 765kV), implementing robust system protection strategies, and performing advanced load modeling. This role is critical to supporting Tesla's ambitious growth in sustainable energy infrastructure, ensuring reliable, efficient, and scalable power delivery. You will collaborate with cross-functional teams, utilities, and regulatory bodies to drive projects from concept to commissioning.

What You'll Do

  • Lead the interconnection process for large electrical loads (e.g., gigawatt-scale) with utility companies, including preparing interconnection applications, conducting feasibility studies, and negotiating agreements to ensure compliance with grid standards (e.g., NERC, IEEE)


  • Design and engineer switchyards, substations, and associated infrastructure at high voltages, including 765kV, 345kV, and lower (e.g., 138kV, 69kV), incorporating transformers, circuit breakers, bus systems, and grounding schemes


  • Develop and implement system protection strategies, including relay coordination, fault analysis, and protective device settings to safeguard equipment and maintain grid stability


  • Perform load modeling and simulation using tools like SKM, ETAP, PSS/E, or ASPEN to forecast power demands, analyze system impacts, and optimize load ramps for dynamic industrial applications


  • Conduct power system studies, including short-circuit analysis, arc flash assessments, harmonic studies, and transient stability evaluations


  • Collaborate with internal teams (e.g., project managers, civil engineers) and external stakeholders (e.g., utilities, EPC contractors) to integrate designs with overall project timelines and budgets


  • Ensure designs comply with relevant codes, standards, and regulations (e.g., NEC, ANSI, local utility requirements)


What You'll Bring
  • Bachelor's Degree in Electrical Engineering or equivalent experience


  • Minimum of 8+ years of experience in electrical engineering, with a focus on high-voltage power systems


  • Proven expertise in interconnecting large loads with electrical utilities, including experience with load studies, queue management, and interconnection agreements


  • Extensive experience designing switchyards and substations at voltages including 765kV, 345kV, and lower, with a track record of successful project delivery


  • Strong knowledge of system protection principles, including relay design, coordination, and testing


  • Proficiency in load modeling and power system simulation software (e.g., ETAP, PSCAD, DIgSILENT)


  • Professional Engineer (PE) license preferred

Practice Questions

💡Technical Questions (3)
  • 1.Walk me through your approach to designing a 345kV switchyard for a gigawatt-scale manufacturing facility, including how you determine the bus configuration and grounding scheme.
  • 2.How do you approach developing a system protection strategy for a large industrial load interconnecting with a utility at 345kV, specifically regarding relay coordination and fault analysis?
  • 3.Describe your process for executing the utility interconnection process for a large-scale dynamic load, from initial feasibility study to final agreement.
🎯Behavioral Questions (3)
  • 1.Tell me about a time you had to negotiate interconnection terms or technical requirements with a utility provider that initially pushed back on your project's load ramp requirements.
  • 2.Describe a situation where you identified a critical flaw or risk during a power system study—such as an arc flash or transient stability issue—late in the design phase of a substation project.
  • 3.Give me an example of a project where you had to align the work of internal cross-functional teams (like civil engineers and project managers) with external EPC contractors to deliver a high-voltage infrastructure project.
🧩Situational Questions (2)
  • 1.You are performing load modeling for a new gigawatt-scale facility and discover that the anticipated dynamic load ramps will likely cause voltage flicker that violates the local utility's interconnection standards. How do you resolve this?
  • 2.During the commissioning of a 345kV substation, the EPC contractor discovers a significant physical interference between a large transformer and the planned bus system, requiring a redesign of the bus routing. How do you handle this while maintaining project momentum?
