As a Principal Engineer, Grid Engineering and Interconnection, you’ll join the team that strengthens grid reliability, supports renewable integration, and advances grid modernization for our clients. You’ll work closely with utilities, independent power producers (IPPs), and independent system operators (ISOs) to deliver power system studies that inform real investment and reliability decisions, while coaching and growing a team of transmission planning engineers. This role is ideal for someone who enjoys working at the intersection of power system analysis, client delivery, and team leadership, brings strong judgment to complex technical problems, and wants to contribute to work that shapes real-world decisions in the energy industry.

• In this role, you will:

• Lead and mentor a team of transmission planning and interconnection study engineers

• Own client relationships and delivery of interconnection, stability, and reliability studies

• Oversee the quality of power flow, voltage stability, transient stability, and short-circuit analyses

• Conduct studies in areas such as generator and load interconnections, transmission planning, and economic analyses

• Prepare and review technical reports and ensure deliverables meet client specifications for reliability, regulation, and quality

• Manage project scope, staffing, cost, and schedule across a portfolio of concurrent engagements

• Contribute hands-on to complex or high-impact studies alongside the team

• Partner with global colleagues to scale capacity and deliver consistent, high-quality work

• Drive business development by shaping proposals, scoping engagements, and identifying new client opportunities

• Balance client delivery, team development, and technical quality across competing priorities

• Communicate complex study results clearly to technical peers and executive stakeholders

• Navigate ambiguity and make sound judgment calls on scope, methods, and schedule

• Care about quality, reliability, and the growth of the engineering team

• And even better if you:

• Have prior consulting or client-facing power systems experience

• Hold a master’s or Ph.D. in power systems engineering

• Have led studies across multiple ISOs (for example, ERCOT, MISO, CAISO, PJM, NYISO, ISO-NE, or SPP)

• Have contributed to open-source tools or published technical writing on transmission planning

• Experience and Skills to Qualify Include:

• 10+ years of power systems analysis experience, including 3+ years leading engineers, projects, or client engagements

• Bachelor’s degree in electrical engineering

• Deep proficiency with PSS/E for load-flow and transient stability analysis, and ASPEN for short-circuit analysis

• Experience with at least additional planning tool such as PSLF, TARA, PSCAD, or DSA Tools

• Proven experience leading stability studies, congestion analysis and cost modeling, or cluster feasibility studies across or more ISOs

• Working knowledge of synchronous generators, motors, power electronic inverters, wind turbines, solar photovoltaic (PV) systems, and battery energy storage systems (BESS)

• Working knowledge of reliability standards, interconnection processes, substation layout, and protection and control

• Demonstrated ability to manage client relationships and deliver on time and within budget

• Strong oral and written communication skills

At E Source, you’ll work alongside people who are thoughtful, curious, and deeply knowledgeable about utility and energy systems. We value clarity over jargon, substance over flash, and collaboration over ego. You’ll have the opportunity to grow your skills, contribute to meaningful work, and help shape a company that plays a real role in how the energy future unfolds.

• What you can expect:

• Excellent insurance options, including medical, dental, and vision plans; company-paid life insurance; company-paid long- and short-term disability insurance; medical and dependent-care flexible spending plans, and paid parental leave.

• A flexible time off (FTO) policy that provides paid time away from work, approved by your manager, while ensuring business needs, workload commitments, and appropriate coverage are maintained.

• A 401(k) plan with a 3% employer match.
