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 LangGraph 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 contributions in this role will directly address critical challenges, such as:

• Strategic Direction and Evolution: Proactively identifying opportunities and leading initiatives to define and refine the strategic direction of the SRE team within the data platform context, specifically contributing to the Archipelago evolution plan.
• Architectural Leadership: Providing architectural guidance and expertise for the design, implementation, and maintenance of highly reliable, scalable, and performant data infrastructure.
• Incident Management and Resolution: Leading the effort in establishing and refining incident response protocols, ensuring efficient resolution of critical data platform issues, and driving post-incident analysis for continuous improvement.
• Performance Optimization: Identifying and implementing solutions to optimize the performance, efficiency, and resource utilization of the data platform.
• Automation and Tooling: Championing the development and adoption of advanced automation solutions, including leveraging AI and AI agents with new frameworks like LangGraph, for tasks such as data platform crash resolution and coordination. You will also oversee the development of more classical automation tools.
• Proactive System Health: Designing and implementing advanced monitoring, alerting, and anomaly detection mechanisms to ensure the proactive identification and prevention of potential issues. This includes exploring the concept of a "swarm of AI agents" to act as a lubricant for the Data Platform, focusing on predictive analytics and notifying responsible teams preventatively.
• Mentorship and Leadership: Mentoring less senior SREs, fostering a culture of reliability engineering excellence, and leading technical initiatives within the team.

• Service Level Objectives (SLO) Management: Defining, monitoring, and enforcing SLOs for critical data platform services.
• System Observability: Implementing and maintaining comprehensive monitoring, logging, and tracing solutions across the data platform.
• Toil Reduction: Identifying and automating repetitive manual tasks to improve team efficiency and focus on strategic initiatives.
• Disaster Recovery and Business Continuity: Developing and testing disaster recovery plans to ensure the resilience of the data platform.
• Capacity Planning: Forecasting resource needs and planning for infrastructure scaling to meet anticipated demand.
• Performance Engineering: Optimizing system performance and addressing bottlenecks to ensure efficient operation.
