* Job Description:

** The
** Field Applications Engineer, Electrical Systems
** will play a critical role in the design, validation, testing, and deployment of Nextpower’s utility-scale PV + Storage power plant solutions. This hybrid role combines responsibilities across Electrical Balance of System (eBOS) engineering and Field Application Engineering, supporting both product development and real-world implementation.

The engineer will work across the full lifecycle of electrical systems—including design, integration, testing, commissioning, and field support—ensuring reliable, compliant, and high-performance operation of Nextpower’s power block technologies.

This position is based in Fremont, California, with periodic travel to test facilities and project sites.
** Summary
* * This role bridges product development and field execution, combining deep electrical system design expertise with hands-on testing and deployment experience. The ideal candidate thrives in both engineering and field environments and is passionate about advancing next-generation PV + Storage power plant solutions.
** Key Responsibilities
**** System Design & Integration
*** Develop and validate eBOS designs, including DC and AC collection systems, cabling, grounding, protection, and interconnection components.
* Define and manage system interfaces between PV modules, DC/DC converters, inverters, transformers, switch gear, and control systems.
* Generate and review electrical design documentation such as single-line diagrams (SLDs), wiring schematics, and interconnection drawings.
* Collaborate with product and systems engineering teams to integrate eBOS into PV + Storage power block solutions.
** Testing, Validation & Commissioning
*** Conduct system-level testing and validation at Nextpower test facilities (Fremont, San Jose, and Brazil) and at project sites.
* Execute performance, functionality, and grid compliance testing for inverters, battery systems, and PV optimizers.
* Analyze test results and M&V data to identify performance improvements and design optimizations.
* Develop and enhance testing infrastructure, procedures, and capabilities.
** Field Support & Troubleshooting
*** Support commissioning and deployment of power plant systems in the field.
* Provide technical guidance and troubleshooting support for electrical and system-level issues.
* Perform root cause analysis and implement corrective actions for field and development issues.
* Diagnose and resolve electrical faults, including grounding and communication issues in PV + BESS systems.
** Standards, Compliance & Documentation
*** Ensure compliance with applicable codes and standards (NEC, UL, IEEE, IEC, NFPA).
* Develop and maintain technical documentation, including commissioning procedures, installation guidelines, and maintenance processes.
* Support grid interconnection and compliance requirements (e.g., protection coordination, voltage/frequency response).
** Cross-Functional Collaboration
*** Partner with R&D, product engineering, quality, and supplier teams to improve system design and reliability.
* Work with suppliers to evaluate and qualify electrical components and ensure quality standards are met.
* Support customer-facing activities and ensure successful deployment and operation of systems.
** Qualifications & Experience
**** Required
* ** Bachelor’s degree in Electrical Engineering, Power Systems Engineering, or related field.
* Minimum 5 years of experience in electrical engineering, power systems, solar PV, or energy storage.
* Strong understanding of:
+ AC/DC power systems and distribution  + Power conversion systems (inverters, DC/DC converters)  + eBOS function and application  + Electrical protection, grounding, and coordination
* Experience with electrical design documentation (SLDs, schematics).
* Hands-on experience with testing, commissioning, and troubleshooting power systems.
* Familiarity with industry standards (NEC, UL, IEEE, IEC).
* Strong analytical, problem-solving, and communication…
