Senior Software Engineer, Application Migration

About the role

We are seeking a senior engineer to design and build the infrastructure behind our generative AI platform and code migration tools. You will focus on high-performance data systems, orchestration layers, and database interactions to help customers modernize their legacy workloads. The role requires deep collaboration with cross-functional teams to translate complex business requirements into scalable technical solutions. You will be responsible for ensuring that the systems you build are robust, efficient, and aligned with enterprise standards. This position is critical in bridging the gap between legacy architectures and modern cloud-native deployments. Your work will directly influence how customers migrate and operate their most critical applications. You will have the opportunity to shape the future of application migration within a high-growth environment. This role is based in Sydney and follows a hybrid work model.
