It goes back to our history of reinventing ourselves for new markets, serious rates of growth year after year, and being ahead of the curve in technology. Those are the achievements of a company that rewards talent and effort in ways that mean the most to the individual.

When you work at SSOE, you work with the best and you're a part of something bigger than yourself. And providing the best possible workplace for our employees gives us a competitive advantage-helping us attract and retain top talent and drive better business results.

As part of our commitment to innovation, all team members will be trained on Microsoft Copilot and empowered to use it as a core tool in their everyday work.

The following duties are typical of the position but are not all encompassing. Responsibilities include those required to deliver quality service on schedule and within budget in a team environment.

• Lead end-to-end HV (high voltage) substation design (typically 69 kV–500 kV):
  • Primary: bus configurations (ring bus, breaker-and-a-half, double bus), equipment layouts, general arrangements, sections/elevations, equipment sizing and ratings (including BIL), conductor/busbar selection, lightning protection, insulation coordination.
  • Secondary/Protection & Control: SLDs/three-lines, protection one-lines, AC/DC schematics, wiring diagrams, panel layouts, cable schedules, I/O lists, RTU/SCADA integration, points lists, relay logic/settings.
  • Grounding/Earthing: ground grid design and studies (touch/step voltages), grounding plans and details.
  • Auxiliary systems: station service AC, DC systems and battery sizing, charger selection, UPS as required.
• Prepare technical specifications/datasheets and perform vendor bid evaluations for transformers, breakers, disconnects, instrument transformers (CTs/PTs/CCVTs), surge arresters, control panels, cables, raceways, and ancillary equipment.
• Perform and/or review power system studies: short-circuit, protection coordination, arc flash (per NFPA 70E/IEEE 1584), load flow as applicable; contribute to insulation coordination and ferroresonance/temporary overvoltage assessments as needed.
• Ensure compliance with NEC (NFPA 70), NEMA standards, and NERC reliability and cyber requirements (e.g., PRC/CIP awareness for protection and SCADA).
• Coordinate multi-discipline inputs (civil/structural, telecom, automation) and interface with utilities, ISO/RTOs, and client engineering teams.
• Lead QA/QC reviews, check deliverables from junior engineers/designers, and enforce internal standards and best practices.
• Provide construction and commissioning support: respond to RFIs, review submittals, support FAT/SAT, and prepare as-built documentation.
• Support proposals/estimating, work plans, schedules, level-of-effort, and client presentations; contribute to standardization and process improvements.
• Mentor junior engineers and CAD/BIM designers; help build technical depth in the Mumbai team.

What will you bring?

• Bachelor’s degree (B.E./B.Tech) in Electrical Engineering required; M.E./M.Tech preferred.
• 12 -18 years of progressive experience delivering detailed design for US-based HV (high voltage) substations.
• Extensive hands-on experience in the production and verification of comprehensive design packages, including SLDs/three-lines, GA/layouts, sections, grounding, raceways, cable schedules, wiring/schematics, protection one-lines, BoMs, and study reports.
• Strong comprehension of protection schemes applicable to transmission and distribution substations, encompassing line, transformer, bus differential, distance, breaker failure, and reclosing, along with relay setting philosophies.
• Proficient in utility interconnection and familiar with standards set by major US utilities; skilled in interpreting and applying client design manuals.Exceptional communication abilities and experience in client interactions; adept at leading meetings, conducting design reviews, and addressing technical challenges.
• Exceptional communication and coordination abilities.
• Must be adaptable to work during evening hours to ensure communication with stakeholders in the USA.

Strong command of NEC, NEMA, and NERC requirements; practical familiarity with:

• IEEE/ANSI standards (e.g., IEEE 80/81 grounding and testing, ANSI C37 switchgear/breakers, IEEE 242/399 as applicable).
• NESC for substation clearances/approaches and interface with lines.
• NFPA 70E for arc-flash safety labeling and boundaries.
• Experience with NERC PRC (for instance, PRC-005, PRC-023, PRC-027) compliance implications related to protection design and documentation; knowledge of NERC CIP considerations for substation networks and SCADA systems.
• Proficient understanding of IEC 61850, DNP3, and the relay families from SEL, GE, and Siemens, along with their configuration tools.
• Capability to execute SEL Relay Programming is considered an advantage.
• Familiarity with renewable interconnections, battery energy storage systems, and utility-scale collector substations.
• Knowledge of US ISO/RTO processes (such as PJM, MISO, ERCOT, CAISO) and specific substation standards for utilities.
• Previous experience in an EPC environment and exposure to construction and commissioning activities.

Tools/Software:

• Power system analysis tools: ETAP, SKM Power Tools, CYME (any combination).
• CAD/BIM software: AutoCAD, MicroStation; Revit is an advantage.
• Relay configuration software: SEL Acselerator.
