Operations and Maintenance Engineer

Rooftop Energy Tech Sdn Bhd (Rooftop Energy) is hiring an Operations and Maintenance (O&M) Engineer to take ownership of post-commissioning performance across our installed solar portfolio, and to lead the rollout of our O&M service package.

Rooftop Energy is the solar subsidiary of Dynasynergy Group. We have commissioned 4.3 MWp of grid-connected solar to date, with an active Engineering, Procurement, and Construction (EPC) pipeline of more than RM9 million. We also operate RooftopIQ, our Software-as-a-Service (SaaS) platform for solar proposal automation and asset management. Our work spans EPC delivery, platform development, and the integrated Internet of Things (IoT) devices that connect every site we deliver.

This is the first dedicated O&M role at Rooftop Energy. You will define how we operate sites for the long term, productise the service, and grow with the portfolio.

• First dedicated O&M owner at Rooftop Energy
• Productise the Rooftop Energy O&M package: service tiers, scope, response times, and contract terms
• Own day-to-day performance of every commissioned site, monitored through RooftopIQ
• Reports to the Chief Engineer
• Performance-linked incentive package tied to the operating results of the O&M team

Define and launch Rooftop Energy's O&M offering. Set the service tiers, scope, response times, exclusions, pricing logic, and contract templates. Work with the EPC sales process so every new project is sold with an O&M tail attached.

Set baseline expectations for performance ratio, specific yield, and availability across the portfolio. Monitor sites through RooftopIQ, intervene early when a site drifts, and run root-cause analysis on underperformance. Partner with the platform team to make sure the alerts, dashboards, and customer reports you need actually exist.

Plan and run preventive maintenance schedules across the portfolio. Diagnose, dispatch, and close out corrective work. Coordinate site visits, subcontractors, parts logistics, and access. Keep maintenance records clean enough to defend warranty claims and underwrite future O&M renewals.

Work with the platform and devices teams on the IoT layer deployed on every site, including inverters, gateways, power loggers, and sensors. Make sure hardware in the field is healthy and telemetry is flowing. Feed device-level findings back into product fixes rather than absorbing them into manual workarounds.

Produce clean monthly performance and savings reports for site owners. Be the technical face of Rooftop Energy after handover. Build the credibility that converts one-off EPC customers into multi-year O&M contracts.

Document the O&M function as you build it: checklists, inspection forms, fault libraries, escalation paths, and standard operating procedures. Feed that operating discipline back into the wider engineering team.

• Three or more years of hands-on engineering experience on grid-connected solar PV systems
• Demonstrated experience designing and commissioning grid-connected PV systems, including sizing, single-line diagrams (SLDs), array layout, and ATAP submissions
• Working knowledge of inverters, string monitoring, protective devices, and TNB grid-connection requirements
• Comfortable diagnosing underperformance from monitoring data, not only from site visits
• Willingness to travel to commissioned sites across Peninsular Malaysia, Sabah, and Labuan as needed
• Strong written and spoken English. Bahasa Malaysia is a plus.
• Hands-on, accountable, and self-managing

• Grid-Connected Photovoltaic (GCPV) certification, or active candidate for one
• Practical exposure to IoT devices in an industrial setting, including gateways, modems, monitoring hardware, basic networking, and cellular or LoRa connectivity
• Chargeman certification (BO/A4 or higher)
• Prior experience scoping or running a solar O&M offering: service tiers, response times, and contract terms

• You take ownership without being asked. If a site is underperforming, you do not wait for a ticket.
• Equally comfortable on a roof, in a meeting room with a customer, and at a desk reading inverter logs.
• Process-minded but not bureaucratic. You build the standard operating procedures because the work needs them.
• Direct with subcontractors, suppliers, and customers when something is wrong. Polite, but not hesitant.
• You want to build a function, not maintain one someone else built.

• First in seat. You define how O&M works at Rooftop Energy: package, process, standards, and team.
• Real assets, real customers. 4.3 MWp already commissioned and a growing pipeline behind it.
• Platform-backed. RooftopIQ gives you a proper monitoring and asset-management platform to work with, not spreadsheets and screenshot dashboards.
• Performance-linked incentive. The role carries an incentive package tied directly to the operating performance of the O&M team. Strong execution is rewarded.
• Visible scope. Direct line to the Chief Engineer and the Chief Executive Officer. O&M is recognised internally as a strategic revenue stream.
• Path to lead. As the asset base grows, this role grows into the head of the O&M function with a team underneath.

Send your CV with a short note on the largest portfolio of solar assets you have personally owned the performance of. Tell us your monitoring setup, the worst underperformance issue you caught, and how you fixed it. If you have ever helped scope or sell an O&M package, tell us what worked and what did not.
