1. Pre-Sales Design & Technical Proposals

• Develop technical proposals and design deliverables for solar and BESS projects.
• Prepare and optimize PV layouts, Single Line Diagrams (SLD), Bill of Materials (BOM), and system sizing.
• Perform PVsyst simulations, energy yield analysis, shading analysis, and other technical assessments to support project proposals.
• Conduct BESS sizing and energy storage calculations based on customer load profiles, operating requirements, and proposed system configuration.
• Ensure designs consider site conditions, customer requirements, applicable codes, and project constraints.
• Review and evaluate RFPs/TORs, and other technical requirements to identify project scope, design criteria, technical specifications, deliverables, and compliance requirements.
• Translate RFP/TOR requirements into appropriate design assumptions, system configurations, technical solutions, and proposal deliverables.
• Identify technical clarifications, risks, constraints, and deviations and coordinate with the Sales team as necessary.

2. Site Assessment

• Conduct site inspections to assess roof/land conditions, available installation areas, electrical infrastructure, access, shading, and other site constraints.
• Gather and validate technical information required for pre-sales design and project evaluation.

• Revise designs and technical proposals based on customer requirements and commercial strategy.

4. Design Quality & Documentation

• Ensure accuracy, consistency, and completeness of all pre-sales design outputs.
• Maintain standard templates, design assumptions, calculation methodologies, and technical documentation.
• Coordinate with Engineering, Project Management, and other relevant teams during project handover.

QUALIFICATIONS AND EXPERIENCE:

• Registered Electrical Engineer (REE)
• Strong understanding of photovoltaic systems, PEC/IEC standards, and construction practices.
• Strong analytical and problem-solving skills
• Proficiency in PVsyst, AutoCAD, and relevant design tools
• Knowledge of BESS sizing and energy storage applications
• Ability to interpret electrical drawings, load profiles, and site information
• Proven ability to manage multiple design projects simultaneously while maintaining accuracy and efficiency.
• Eagerness to learn and apply new technologies in a dynamic work setting.
• Attention to detail and accuracy
• Ability to translate technical requirements into practical and commercially viable solutions
• Good communication and coordination skills

WHAT WE OFFER:

• Competitive salary.
• Benefits including leave entitlements, 13th-month pay, annual performance bonus, health insurance, and all mandatory statutory benefits.
• Opportunity to learn and grow in a truly supportive, collaborative, dynamic, and diverse environment.
