Senior Electrical Engineer

Full Time American Fork, UT, US

About the Role

Lion Energy's Commercial & Industrial (C&I) product line — including the POWERsave Cabinet Series — is a pre-assembled, scalable battery energy storage system deployed at commercial and industrial facilities for peak shaving, energy cost reduction, and microgrid applications. As deployment volume grows and a new generation of the commercial EMS/BMS hardware platform is developed, we need a senior electrical resource who can sit at the intersection of Sales, field installation, and Product Engineering.

This role is field-facing today: you'll be the primary technical point of contact for installation issues, review installation blueprints before systems go in the ground, and advise Sales on product fit during the sales process. As product improvements reduce the field-support burden over time, the role will shift toward supporting electrical engineering work on the new C&I hardware platform. You'll report directly to the CTO.

Key Responsibilities

Field & Installation Support (primary focus today)

• Serve as the primary technical point of contact for electrical issues on deployed C&I systems (POWERsaveCabinet Series), including PCS inverters, BMS/EMS-Pro, battery/PDU wiring, and grid islanding relays.
• Review installer- and EPC-submitted single-line diagrams and installation blueprints for code compliance and system fit before deployment.
• Diagnose and resolve field electrical issues remotely; travel on-site for escalations thatcan'tbe resolved otherwise.
• Feed recurring field issues back to Product Engineering to reduce future installation friction.

Sales & Pre-Sale Engineering Support

• Partner with Sales during the sales process to evaluate site conditions and advise on system sizing, configuration, and product fit for prospective C&I customers.
• Provide technical input on proposals covering electrical requirements, interconnection, and code compliance.
• Act as the technical liaison between Sales, Product Engineering, and external installers/EPCs/customers.

Product & Hardware Engineering Support (growing focus over time)

• Support Product Engineering on electrical design and validation for the next-generation commercial EMS/BMS-Pro hardware platform.
• Contribute to schematic review, wiring diagrams, and system-level electrical integration across PCS, BMS, EMS, and grid islanding components.

Compliance

• Maintain and improve installation guides, technical bulletins, and field documentation.

Required Qualifications

• BSEE with a power systems concentration, OR equivalent hands-on electrical experience (e.g., senior/master electrician with substantial commercial & industrial power systems background).
• 5+ years working with commercial/industrial electrical systems; direct experience with battery energy storage, solar PV, or power electronicsstronglypreferred.
• Working knowledge of the National Electrical Code, particularly Article 706 (Energy Storage Systems).
• Demonstrated ability to read and evaluate single-line diagrams, wiring schematics, and site electrical plans.
• Strong communicationskills — comfortable acting as the technical voice in customer- and sales-facing conversations.
• Willingness to travel up to 25% for site visits and installation escalations.

Preferred Qualifications

• Direct experience with UL 9540/9540A/1973/1741 listed systems.
• Familiarity with grid interconnection standards (e.g., IEEE 1547) and microgrid/islanding system design.
• PE license, or journeyman/master electrician license.
• Hands-on experience with lithium (LiFePO4) battery systems, PCS inverters, and BMS/EMS platforms.
• Prior experience at a small company or startup, comfortable wearing multiple hats across engineering, sales support, and field work.
