Job Description

We are looking for a Solutions Architect (C&I Solar) to join our growing renewable energy team. This is a technical, client-facing role responsible for owning the front end of our Commercial & Industrial (C&I) solar opportunities - from understanding the client's site and energy requirements to developing a technically sound and costed solar solution. You will work closely with clients, Business Development (BD) and our EPC/installation team to assess feasibility, develop preliminary system designs, prepare project costing and provide the technical foundation for commercial proposals.

Key Responsibilities:

Conduct feasibility studies and site assessments at C&I premises, including evaluation of usable roof area, structural loading, orientation, shading, roof condition, cable routes and electrical/plant room access.
Engage with clients to understand their energy requirements, load profile, electricity consumption, tariff, budget and preferred financing model, including outright purchase, PPA or leasing.
Develop preliminary solar PV system designs, including array layouts, string configurations and inverter selection based on site conditions and client load profiles.
Perform energy yield and system sizing analysis using PV design and simulation tools such as PVsyst, Helioscope or equivalent.
Prepare project costing and Bill of Quantities (BOQ), covering equipment, balance of system (BOS), mounting structures, installation and other technical requirements.
Assess regulatory and grid connection requirements, including SP PowerGrid, EMA and LEW/QP requirements, and identify potential technical, cost or timeline implications.
Prepare clear and structured technical scope and costing packages for the BD team to develop commercial proposals.
Support BD during tender submissions, client presentations, negotiations and technical clarifications.
Work closely with the EPC/installation team to ensure proposed solutions are practical, buildable and aligned with project specifications and PV layout standards.
Coordinate with LEW/QP on formal electrical designs, Single Line Diagrams (SLD) and regulatory submissions where required.

Requirements:

Degree in Electrical, Mechanical, Energy Engineering or a related discipline.
At least 3 years of relevant experience in solar PV design, C&I EPC, renewable energy solutions or technical pre-sales/solutions roles.
Strong understanding of C&I rooftop solar PV systems and the ability to assess site and roof feasibility.
Good knowledge of LV electrical systems, grid connection requirements and solar PV system components, including modules, inverters and protection systems.
Experience in project costing, BOQ preparation and the ability to validate and defend technical assumptions and pricing.
Working knowledge of Singapore's solar regulatory and grid connection requirements, including SP PowerGrid, EMA and LEW/QP requirements.
Proficiency in solar PV design and simulation software such as PVsyst, Helioscope or equivalent, as well as AutoCAD.
Strong client-facing and communication skills, with the ability to explain technical concepts and trade-offs clearly to non-technical stakeholders.
Strong analytical and problem-solving skills with a practical, commercially minded approach.

Why Join Us

Be part of the growing renewable energy and solar industry.
Own the technical solution from initial site assessment through to a buildable and costed project scope.
Work directly with clients and cross-functional teams across BD, EPC and project delivery.
Enjoy a role focused on technical solutions and project development, rather than cold-calling or pure business development.
Gain exposure to a wide range of C&I solar projects and commercial energy solutions.
