【TENG2102】Cloud Engineer - DBA (DBRE)

【About the Role】

在 SHOPLINE，資料庫不只是「維護」，而是要當成一個需要被工程化、自動化、可觀測的可靠系統來經營。我們的服務建構在 AWS 雲端之上，資料庫採用雲端託管服務與自建環境並行的混合架構，技術上會接觸到 AWS、MongoDB、NewSQL、Kubernetes、Terraform 等。身為 DBA / DBRE，你會和架構師、後端工程師、Cloud 團隊一起，確保我們電商 SaaS 平台在高流量、跨市場環境下的資料庫穩定、安全且可擴展，並透過 IaC 與監控把重複性的維運工作自動化掉。

【What you'll be doing】

- Ensure the integrity, security, and availability of databases through proper design, implementation, and maintenance. (~30%)

- Manage and deliver database infrastructure with Terraform / IaC, making changes version-controlled, reproducible, and reviewable.

- Design and operate highly available architectures; own capacity planning, backup/restore, and disaster recovery (DR) drills to safeguard data and service continuity.

- Support multi-region / cross-market database architectures, scaling and optimizing as the business grows.

- Optimize database performance through tuning, indexing, query optimization, and slow-query analysis. (~25%)

- Collaborate with architects and software engineers to integrate database solutions into the application architecture. (~20%)

- Take ownership of database-related tasks and features, ensuring their timely and successful completion.

- Establish monitoring and alerting to proactively identify and resolve issues. - Participate in production incident handling, debugging, and root cause analysis, delivering effective solutions.

- Explore and adopt AI / LLM for database operations (e.g., intelligent diagnostics, query optimization suggestions, incident root cause analysis, operational automation), turning them into tools the team actually uses.

- Document processes, configurations, and runbooks for reference and future maintenance.

【Who we are looking for】

- Solid hands-on experience operating databases in production (DBA / DBRE / database-focused SRE all welcome).

- A degree in Computer Science, Information Management, Electronic Engineering, Information Engineering, or related fields — or equivalent practical ability (including but not limited to these majors).

- Hands-on MongoDB operations experience (any architecture).

- Comfortable operating and optimizing at least one database.

- Familiarity with query optimization and troubleshooting techniques.

- Comfortable with Linux / bash shell.

- Able to take ownership, with strong attention to detail, and see things through to completion.

- A lifelong learner who picks up new technologies quickly.

【It'd be a plus if you have】

- In-depth experience with a second database; NewSQL is a plus.

- Hands-on Terraform / IaC experience.

- Hands-on experience using Kubernetes (K8s).

- Experience operating cloud managed services.

- Interest or hands-on experience using AI / LLM to assist database operations.

- MongoDB Associate DBA certification.

- Experience building or maintaining e-commerce platforms or high-traffic SaaS.

- Experience working in a fast-paced startup environment.
