Solar Systems Designer

SIGNATURE SOLAR LLC•Irving, TX

About The Position

The Solar Systems Designer is the technical authority within the sales organization. This is not a management role and not a frontline selling role. It is a specialized individual contributor position focused on enabling others to close more effectively. The Solar Systems Designer maintains deep expertise across all products and services, understands the technical, operational, and regulatory landscape, and serves as the internal expert for complex deal support. Over time, this role is expected to scale alongside the organization, with potential alignment to specific regions or territories as sales volume grows.

Requirements

Product mastery: Expert-level knowledge across all offered products — solar PV systems, battery storage, roofing, windows, doors, insulation, HVAC, and anyadditionalservice lines. Must know specifications, application ranges, common failure points, and differentiators.
System design: Ability to buildaccuratesolar system designs using proposal tools — understanding shading analysis, production modeling, battery sizing, and load matching at a level that exceeds what a consultant is expected to know.
Incentive programs: Deep fluency in federal ITC, state-level incentive programs (including Illinois Shines, Texas programs), utility net metering policies, and financing incentive structures. Must be able to explain these accurately to technically sophisticated customers.
Pre-contractlogistics: Understanding of the post-sale operational process — permitting, HOA approvals, utility interconnection, installation sequencing — sufficient to setaccuratecustomer expectations and prevent cancellations rooted in misaligned expectations.
Customer communication: Comfortable engaging directly with technically sophisticated or skepticalcustomers;can translate complex concepts into plain language withoutover simplifyingtothe point of inaccuracy.
Sales support orientation: This role exists to helpconsultantsclose deals — the SME must have the disposition to serve internal stakeholders with the same urgency and professionalism as external customers.
Quality and accuracy: Low tolerance for technical inaccuracy in proposals, scripts, or customer-facing communication. Comfortable pushing back internally when something is wrong.
3+ years of experience in residential solar sales, solar project management, or solar field engineering — with direct exposure to customer-facing technical questions.
Prior experience as a senior solar consultant, sales engineer, or technical trainer in a high-volume sales environment.
Hands-on familiarity with solar proposal platforms (Aurora Solar,OpenSolar, Pylon, or similar) at an advanced user level.
Working knowledge of NEC electrical code as it applies to residential solar and battery systems — notrequiredtodesign tocode but must understand the constraints.

Nice To Haves

Familiarity with roofing, HVAC, orinsulationproduct lines is a strong differentiator given the multi-trade nature of the organization.
NABCEP certification or equivalent technical credential preferred, notrequired.

Responsibilities

Build complex system designs within proposal software (e.g., multi-array solar designs, battery + solar configurations, hybrid HVAC/solar bundles) that exceed the scope of what a standard consultant can configure independently.
Join live customer consultations (calls, video, or in-person) when a deal requires deep technicalexpertise— answering customer questions with authority and accuracy on system performance, equipment specifications, installationlogistics, and incentive programs.
Provide pre-contract logistical and operational guidance: HOA compliance, utility interconnection timelines, roof load calculations,permittingexpectations, and installer coordination details that affect the customer's buying decision.
Develop andmaintaina living internal knowledge base of product specs, technical FAQs, incentive structures (ITC, state rebates, utility programs), and common objection responses.
Support proposal review — QA complex proposals from consultants before they are presented to customers, flagging design errors, pricing inconsistencies, or missing adders.
Contribute to consultant training by running product knowledge sessions, building reference materials, andparticipatingin deal review calls.
Stay current on equipment changes (new panel models, inverter specs, battery chemistries), incentive program updates (IRA, Illinois Shines, SREC programs, utility rebates), and evolving installation standards.
Collaborate with the Systems Integrator to ensure proposal tools reflectaccurateproduct and adder configurations — providing the product-side input the Systems Integrator needs to configure systems correctly.
Provide feedback loops to Director of Sales on recurring technical gaps in the sales team's knowledge that signal training needs.
