Collaboration & Improvement:Enabling product teams to meet non-functional requirements and ship reliably and driving continuous improvement through documentation mentorship and uplift of engineering standards.
Our Service Operation Management team plays a crucial role in enhancing organizational efficiency and productivity through automated systems and processes. This role covers a broad technical scope including cloud networking Kubernetes observability security and FinOps with end-to-end ownership influencing architecture standards and operational strategy.
