Job summary

Rooftop Energy invites a Full-Stack Engineer to build GTM tools for the solar EPC team in Malaysia. You will craft systems to find, qualify and win rooftop projects, from lead screening to proposal delivery, while collaborating with Project Engineers weekly.

You will work on prospecting, automation, dashboards and data pipelines, using Python/JS, APIs and datasets. This role blends software with energy sales in a dynamic solar business.

Qualifications

• A degree in engineering, computer science or related field, or equivalent evidence of what you have built.
• You write code to get things done: Python or JavaScript/TypeScript, working with APIs, databases and messy spreadsheets.
• Something you built on your own initiative and can show us: a side project, a scraper, an automation, a small app.
• Comfortable cleaning, joining and scoring large, imperfect datasets, and building spreadsheet models others can check.
• You use AI tools in your own work every day, and can explain where they help and where they fail.
• Genuine interest in solar and how businesses buy it, and a willingness to learn electricity tariffs, return on investment and the commercial case quickly.
• Clear written English, since much of the outreach you build will be in writing.

Responsibilities

• Own the EPC team's GTM tooling. Build, run and maintain the tools that take a lead from first contact to a signed proposal, and decide with the Chief Engineer what to build next.
• Prospecting and lead screening. Build prospect lists of commercial and industrial buildings across Malaysia from public data, company registries, industrial park listings and satellite imagery.
• Rank them with a lead-screening tool that scores roof size, building type, tariff category and indicative system size.
• Outreach automation. Build and run automated email and LinkedIn sequences; enrich decision makers' contact details and log replies.
• Proposal automation. Build on the team's proposal tools: BOMs, financial models, roof-plan take-off and client deck.
• Pipeline automation and reporting. Connect tools to the EPC Master Tracker and report on conversions by channel.
