Jobs to be Done

As technical co-founder, you will turn FaiSabai from a validated concept into the platform Thai homes and installers run on.

Ship the homeowner journey. Build the flow from "send your bill on LINE" to system design, saving forecast, funding and installation tracking, and get it into the hands of real households.
Build the installer stack. Design and quoting software that turns hand-drawn load sizing, single-line diagrams and savings forecasts into minutes of work, plus the tools that run leads, procurement and payment on completion.
Make the savings real. Choose, integrate and deploy the home monitoring device. Prove actual savings land within 10% of the forecast, and push self-consumption above 65% by shifting load into the generation window.
Own the data. Turn hourly load data from Thai homes into better sizing, sharper forecasts and a dataset no generic irradiance model can match.
Build toward the VPP. Architect monitoring and control so a growing fleet of homes, batteries and EV chargers can join demand response and a virtual power plant.
Hit the pilot gates. Help take FaiSabai from 10–20 homes to 100, then 1,000, against clear thresholds on cost to acquire, saving, install time and NPS.
Build the team. Hire and lead the engineering and product team, and set the technical bar for the company.

Your Ideal Experience

We are not looking for a pure software engineer or a solar salesperson. The ideal candidate is a technical builder who knows how Thai homes buy solar.

You have sold solar to Thai households, or worked with installers, and understand how residential solar is sold and installed.
You have built and shipped a product end to end, platform and app, with real users.
You have connected-energy or IoT experience: home energy management, inverter or battery monitoring, smart meters or EV charging.
You understand energy data and the grid well enough to build toward VPP and demand response.
You have a 0→1 track record, and have hired and led an engineering team.
You complement a commercial co-founder: you own product and tech while Sirapat owns demand and partners.
You are Thailand-based, or willing to be. Thai speaker strongly preferred.
You are full-time and fully committed.

Bonus: you have worked at a home-energy platform or solar installer, in Thailand, Southeast Asia or globally.

Most importantly, you want to make sure every Thai home that goes solar gets the saving it was promised, and build the platform that does it.

This is your company. We're here to help.
