Collaboration is key, and we work together swiftly and respectfully, embracing adaptability and resilience in all we do. Principal Systems Engineer We are looking for a Principal Systems Engineer, based in Singapore, to lead the architecture, design, and development of the systems software that automates the management of our bare-metal GPU clusters across Asia-Pacific. This is a highly technical leadership role for an engineer who has built bare-metal clouds and wants to apply that experience to AI infrastructure at significant scale. You will operate at the intersection of systems engineering and back-end software, building scalable, fault-tolerant control-plane services that provision, validate, operate, and remediate thousands of GPU nodes and the fabrics that connect them. You will partner closely with platform, networking, hardware, data centre, and deployment teams across APAC, Europe, and the US. As a Principal Engineer, you will serve as a technical authority across compute, network, and control-plane domains, setting engineering standards, mentoring senior engineers, and guiding critical architectural decisions as we build out our APAC systems and network engineering organisation.
