DevOps Engineer

[Introduction to Platform Department]

The Hyperconnect Platform Department consists of members from the SRE Team, DevOps Team, Platform Development Team, and Data Engineering Team, who collectively provide infrastructure and common platform technologies to all company services, creating business impact. Additionally, they contribute to preventing technology siloization and fostering an excellent engineering culture across the company.

[How the Platform Department Works]

• We don't just create the infrastructure needed by development teams; we provide appropriate system designs that encompass both business and technical requirements. In this process, we lead the overall process of engaging in Q&A with not only the company's development teams but also other stakeholders when necessary.
• We proactively explore various information such as technical metrics, logs, and source code to identify, define, and solve problems located in the blind spots of development teams or SRE/DevOps teams.
• We create documentation on basic design methods and best practices to help development teams or other SRE/DevOps team colleagues solve problems independently.
• We are not content with the current technology stack; we actively explore and adopt new technologies that can better solve problems.

[Introduction to DevOps Team]

• The DevOps team researches and provides public cloud services such as AWS, GCP, Kubernetes, and computing/networking platforms so that all service development teams, SRE, ML/data engineers can easily use the infrastructure. Additionally, the team introduces, develops, and manages various DevOps tools such as CI/CD and IDP (Internal Developer Platform) to enable all engineers to perform development tasks efficiently and deploy without fear.

[If you join the team,]

• You can experience and directly operate flexible and modernized computing and network infrastructure, including operating Kubernetes and service mesh in an AWS public cloud environment.
• You can experience various know-how and best practices for managing a Global Production environment with zero downtime.
• Beyond simply managing developer tools, you can gain experience researching best practices and applying them to systems and development processes.
• You can comprehensively review all development stages, from local development environment setup to production deployment and monitoring, and propose and apply better release systems.
• You can gain experience operating tools and platforms used by all engineers at Hyperconnect, such as AWS, Kubernetes, Okta, GitHub, and Vault, with system admin privileges.
• You can analyze the overall cost of cloud infrastructure and propose and apply code-level improvements beyond simple computing resource changes to minimize costs.
