🗨️ About the Team

• Lunit's Software Engineering (hereafter, "SE") department develops the Lunit INSIGHT product. Within the SE department, the Core Product Engineering team performs the Backend/Application development needed to productize INSIGHT AI models. We translate product requirements into development requirements and build Software as a Medical Device (SaMD) that complies with medical device guidelines.
• Our team's core goal is to ensure the INSIGHT product has optimized performance and reliability so it can operate across diverse countries and deployment environments.

🗨️ About the Position

• The Site Reliability Engineer role sits between development and operations, improving reliability, observability, automation, and operational systems so the INSIGHT product can run stably.
• Rather than simply performing operational tasks, you will discover recurring problems and operational inefficiencies in production, analyze their root causes, and translate the findings into automation, improved observability, and improved operational processes.
• You will collaborate with Lunit International's SRE team, understand differing operational environments and processes, and connect and align the global operating system with the domestic product development environment.

🚩 Roles & Responsibilities

You will design and improve the reliability, observability, deployment automation, and cloud infrastructure operations of the Lunit INSIGHT product to ensure it runs stably. This role is not limited to performing predefined operational tasks. You will identify gaps in the team's current SRE capabilities and operational systems, then define and drive the improvements needed.

• Improve the stability, availability, performance, and operational quality of the Lunit INSIGHT product and related services.
• Design and enhance cloud infrastructure, deployment, monitoring, and operational automation systems.
• Analyze cloud resource usage and cost, and continuously drive cost optimization while considering stability and performance.
• Diagnose, recover from, and perform root-cause analysis on incidents, and prevent recurrence through monitoring, alerting, runbooks, and automation.
• Reliably manage and improve operational configurations and security elements such as per-environment/per-customer settings, certificates, secrets, and access permissions.
