Senior Staff DevOps Engineer

About the role

Sonatus builds the software platform for AI-enabled, software-defined vehicles. Our Korea engineering site is responsible for critical product delivery to major automotive OEMs - it generates 30% of company revenue and operates dedicated build infrastructure, lab hardware, and test environments that must run reliably on-premises. We are seeking a Staff DevOps Engineer based in Seoul to own and modernize the Korea site's on-premises infrastructure: bare-metal Jenkins build servers, enterprise storage, lab networking, and the automation that ties CI/CD pipelines to physical test hardware. This is a hands-on engineering role where you will be the primary infrastructure owner for the Korea site, working closely with the global Engineering Operations team (Sunnyvale, Dublin) to bring consistency and modern practices to a critical production environment. Today, the Korea infrastructure is functional but manually configured - Jenkins controllers and agents set up by hand, storage replication that is undocumented, and release automation built on large monolithic scripts. You will modernize this into a codified, observable, maintainable platform while preserving the team's existing workflows and institutional knowledge.

Responsibilities

• On-premises build infrastructure - Own the Korea Jenkins controller and physical build agents. Manage capacity planning, server health, and reliability for the bare-metal servers that produce ECU firmware builds. Coordinate AWS overflow capacity when on-prem resources are constrained.
• CI/CD pipeline support - Maintain and improve the Korea release automation pipelines (Jenkins shared libraries, Groovy-based release workflows). Partner with the global CI/CD team on consolidation and standardization efforts while ensuring Korea-specific build and release requirements are met.
• Monitoring and observability - Deploy monitoring (Nagios, Prometheus/Grafana, or equivalent) for all Korea on-prem infrastructure: build servers, storage arrays, network equipment, and lab hardware. Replace the current model of "someone notices it's broken" with proactive alerting and dashboards.
• Datacenter operations - Own the physical environment for the Korea server room: coordinate with facilities on power and cooling constraints, manage rack layouts, and plan capacity for future hardware deployments.
• What You Bring

Requirements

• 15+ years in infrastructure, DevOps, or SRE roles, with significant time managing on-premises and bare-metal infrastructure - not exclusively cloud-native environments
• Linux systems administration - You debug production servers over SSH daily: networking, storage, process management, systemd, log analysis
• On-premises infrastructure - Hands-on experience with physical servers, rack management, storage arrays (NFS/SAN), and datacenter operations including power, cooling, and capacity planning
• CI/CD platform administration - Experience operating Jenkins at scale (distributed agents, shared libraries, credential management) or equivalent enterprise CI/CD platform
• Infrastructure as Code - Practical experience with Terraform and Ansible (or equivalent). You've migrated environments from manua
