Energy One Limited Tech Stack

Energy trading software and 24/7 market operations for wholesale energy and carbon markets

Software Development North Sydney, NSW 201–500 employees Founded 2007 Public Company

Energy One operates a dual-revenue model combining ETRM software (energy trading and risk management) with 24/7 managed services for wholesale energy and renewables participants. The stack is dominantly Microsoft (Power BI, SQL Server, Azure, Windows) paired with cloud infrastructure (AWS) and a secondary layer of security tooling (Palo Alto, Zscaler, Cisco), suggesting a mature enterprise platform built on Windows-era foundations now absorbing cloud-native practices. Active hiring across engineering, product, and ops—weighted toward senior roles—aligns with concurrent projects in automation, security hardening ('secure by design'), and an emerging AI-enabled engineering platform, indicating a modernization push beyond legacy ETRM workflows.
