Full Time Remote Solar Design Jobs (NOW HIRING)

SIGNAL ENERGY

Job Profile: Electrical Designer – Utility-Scale Solar

Department: Engineering – Electrical
Reports To: Manager / Senior Electrical Engineer
Location: Houston, TX (preferred) – Remote (U.S.) considered
FLSA Status: Exempt

Position summary

The Electrical Designer develops and coordinates complete AC and DC design packages for utility-scale solar and BESS projects, from early design through Issued-for-Construction (IFC) deliverables. This role supports both Engineer-of-Record (EOR)–led and in-house engineering efforts and ensures that designs meet project scope, schedule, budget, safety, quality, and constructability requirements in alignment with Signal Energy’s core principles.

Essential duties and responsibilities

• Lead the development of PV array and BESS electrical design packages from concept through IFC, including single-line and three-line diagrams, conduit and cable schedules, and wiring details for utility-scale projects.
• Prepare detailed DC collection layouts (stringing plans, combiner boxes, DC feeders) and AC collection layouts (inverters, MV transformers, MV feeders, and terminations) to achieve performance and cost objectives.
• Perform core electrical design calculations including string sizing, voltage drop, conductor and raceway sizing, short-circuit, equipment ratings, grounding, and overcurrent protection in accordance with applicable codes and standards.
• Interpret and implement project design criteria, owner requirements, utility interconnection requirements, and site-specific conditions into cohesive, constructible design documentation.
• Produce plan and detail drawings in AutoCAD (and related tools), including equipment layouts, raceway routing, trench and duct bank details, cable routing plans, vaults, terminations, and grounding diagrams.
• Coordinate closely with civil, structural, high-voltage, BESS, and construction teams to resolve spatial conflicts and ensure electrical designs are fully integrated with grading, roads, drainage, and foundations.
• Support preliminary and detailed energy modeling (e.g., PVSyst or similar) by providing accurate design assumptions, losses, and equipment configurations to optimize system performance and reliability.
• Assist in preparing permit, interconnection, and construction submittal packages, including drawing sets, calculations, and responses to AHJ, utility, and client comments.
• Provide construction-phase design support including RFI responses, design clarifications, redline incorporation, and updates to as-built documentation.
• Contribute to the development and continuous improvement of Signal Energy’s standard details, design tools, workflows, and best practices for utility-scale solar and BESS projects.

Attributes and competencies

• Strong technical foundation in power systems and utility-scale solar/BESS electrical design, including DC/AC collection, grounding, overcurrent protection, and interconnection concepts.
• Comfortable interfacing with clients, EORs, utilities, construction teams, and internal stakeholders, with clear written and verbal communication skills for technical reports, RFIs, and design justifications.
• Proficient in AutoCAD (or equivalent CAD platform) for electrical design; familiarity with PV modeling tools (PVSyst, Helioscope) and power system analysis software (ETAP, SKM, or similar) is preferred.
• Able to manage multiple concurrent projects and deadlines, balancing quality, speed, and cost in a fast-paced EPC environment.
• Collaborative and solutions-oriented team member who operates with integrity and a focus on safety, constructability, and long-term asset performance.
• Self-motivated, organized, and driven to continuously improve design standards, tools, and processes.

Education and experience

• Bachelor’s degree in Electrical Engineering, Renewable Energy, or related discipline; equivalent relevant experience in utility-scale solar design may be considered in lieu of degree.
• 5+ years of experience in solar PV or power systems design, with at least 3 years focused on commercial, industrial, or utility-scale solar and/or BESS.
• Working knowledge of NEC and NFPA; familiarity with NESC, IEEE, and utility interconnection standards is strongly preferred.
• EIT or PE license, and/or NABCEP PV Design or PV Installation certification preferred but not required.

Work environment and location

• Primary location is Signal Energy’s Houston, TX office, with a “Houston-first” approach to hiring and team collaboration.
• Remote work from other U.S. locations may be considered for highly qualified candidates, with periodic travel to Houston and project sites as needed (up to approximately 10%).
• Work is performed in an office environment with occasional visits to active construction sites, requiring adherence to safety protocols and PPE use.
