Technical Sales Advisor

As a Technical Support Engineer at VoltX Energy, you are the technical backbone behind every solar and battery installation we deliver across Australia. You assess whether a customer's home can safely and compliantly take a battery, design solar arrays that make the most of a customer's roof, and act as the technical safety net for our sales team when a conversation needs more than a sales answer.

Your work is grounded in Australian electrical and solar standards — specifically AS/NZS 5139 (battery safety) and AS/NZS 5033 (PV array installation) — and it directly determines whether a job is safe, compliant, correctly priced, and fit for the customer's home. In this role, accuracy matters more than speed: a mistake in technical sales for solar batteries is costly, both for the customer and for VoltX.

Duties and Responsibilities

Site Review & Compliance Assessment

• Assess customer properties for battery installation feasibility in line with AS/NZS 5139—switchboard space and phase (1P/2P/3P), battery location clearances, cable run distances, and rebate documentation.
• Identify site specific cost factors (cable runs, travel distance, site access) that inform accurate, fit for purpose pricing for each customer's home.

Roof Design & Solar System Layout

• Design customer ready solar array layouts in line with AS/NZS 5033, balancing electrical requirements (inverter MPPT and string configuration), roof geometry, and cost efficiency.
• Produce clear, buildable designs that installers can execute without rework, and communicate the final design to the customer for approval before installation.

Technical Support to the Sales Team

• Provide real time technical support to sales advisors and customers by phone, email, SMS, and Microsoft Teams from quick clarifying questions to full technical call take overs for complex enquiries.
• Translate technical and compliance detail into clear guidance that helps the sales team close deals accurately, without over promising on what a system can do.

Quality & Continuous Improvement

• Escalate site or design issues that fall outside standard parameters to the Technical Sales Supervisor rather than guessing.
• Contribute to internal checklists and documentation as standards, products, or pricing change.

Qualifications

• Bachelor's degree in Electrical Engineering or Electronics Engineering (BS EE / BS ECE).
• Working understanding of — or genuine willingness to learn in depth — Australian electrical and solar standards, particularly AS/NZS 5139 (battery safety) and AS/NZS 5033 (PV array installation).
• Strong attention to detail. This role directly affects safety, compliance, and cost, so small mistakes are expensive ones.
• Clear written and verbal English communication, comfortable explaining technical detail to a non-technical audience.

Nice-to-Have

• Prior experience in the solar or battery energy storage (BESS) industry, particularly in the Australian market.
• Familiarity with GreenSketch and Pylon (solar/PV design software) is preferred but not required — training is provided.
• A PRC licence (Registered Electrical Engineer) is an advantage but not required.
• Fresh graduates are welcome to apply, particularly those with Latin honors, scholarships, or other marks of strong academic standing.
