Technical Sales Manager
About The Position
Sineng Electric is a global manufacturer of photovoltaic inverters and battery energy storage systems. Our Americas subsidiary supports utility-scale, commercial and industrial customers across the United States, Canada, and Latin America from our headquarters in Katy, Texas. We're hiring a Technical Sales Manager to be the technical authority behind our Americas sales effort. You'll work alongside our Account Managers from the first customer conversation through contract award — sizing systems, building technical proposals, answering engineering questions from developers, EPCs, and utilities, and making sure our products clear North American code and interconnection requirements. This is a customer-facing role for someone equally comfortable in a design review, on a construction site, and across the table from a utility interconnection engineer.

- Bachelor's degree in Electrical Engineering, Power Engineering, Renewable Energy, or a closely related technical field
- 5+ years in technical sales, application engineering, or solutions engineering for PV inverters, energy storage, or power electronics
- Working knowledge of NEC, UL 1741 SA/SB, IEEE 1547-2018, and North American utility interconnection processes
- Experience with 1500 VDC and medium-voltage PV architectures and/or MW-scale BESS (PCS, BMS, EMS integration)
- Track record writing and defending technical proposals in front of developers, EPCs, and utility engineers
- Strong written and verbal English; able to lead technical meetings independently
- Willing to travel up to 50%, including occasional international travel
- Valid driver's license; able to meet site-access and safety requirements
- Must be legally authorized to work in the United States
Nice To Haves
- Utility-scale BESS projects of 20 MWh or larger
- PVsyst, HelioScope, ETAP, or PSCAD
- Professional working proficiency in Spanish, Portuguese, or Mandarin
- Prior experience at an inverter, storage, or EPC company serving North America
- NABCEP certification or PE license
Responsibilities
- Partner with Account Managers on customer calls, site visits, and technical presentations; translate customer requirements into system architectures and product configurations
- Perform system sizing and product selection for PV inverter and BESS applications across utility-scale and C&I segments
- Own the technical sections of RFP, RFQ, and ITB responses — compliance matrices, single-line diagrams, performance estimates, clarifications, and exception lists
- Advise customers on NEC, UL 1741 SA/SB, UL 9540 and 9540A, IEEE 1547-2018, and state and utility interconnection requirements
- Support customers through AHJ review, interconnection applications, and witness testing
- Deliver product and application training to customers, distributors, EPC partners, and internal sales staff
- Support commissioning escalations alongside our field service team; act as the bridge between customer and factory engineering
- Feed market and field requirements back to factory product management to shape roadmap and certification priorities
- Represent Sineng at trade shows and customer technical workshops
