About the team

We are seeking an experienced and highly motivated Staff Site Reliability Engineer to join our Data Infra SRE team. This critical role will play a pivotal part in shaping the future direction of the SRE team for our Data Platform, contributing significantly to its evolution plan, as we go toward a Data Mesh architecture. We are looking for an individual with a proactive and entrepreneurial mindset who can drive innovation and excellence in reliability engineering. We are seeking an experienced and highly motivated Staff Site Reliability Engineer to join our Data Infra SRE team. This critical role will play a pivotal part in shaping the future direction of the SRE team for our Data Platform, contributing significantly to its evolution plan. While the team was initially formed under specific circumstances, our ambitious decentralization goals mean that we cannot scale effectively without a heavy investment in automation. Therefore, our vision is to heavily invest in automation with AI and AI agents, leveraging new frameworks like Lang Graph alongside more classical automation approaches. For example, we aim to drastically reduce the time and effort involved in data platform crash resolution and coordination through intelligent automation. Another key initiative is to develop a "swarm of AI agents" that will act as a lubricant for the Data Platform, focusing on sophisticated anomaly detection mechanisms and predictive analytics to preventatively detect problems and automatically notify the respective responsible teams. This innovative approach will allow us to achieve unprecedented levels of reliability and efficiency. We are looking for an individual with a proactive and entrepreneurial mindset who can drive innovation and excellence in reliability engineering..

Your role
