A Cloud Engineer/DBA at Shopline ensures database reliability, security, and scalability for their ecommerce SaaS platform, using AWS, MongoDB, NewSQL, and Kubernetes. They automate operations with Terraform, optimize performance, and collaborate with engineers to maintain high availability across multi-region environments.
【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. - 透過適當的資料庫設計、建置與維護，確保資料庫的完整性、安全性與可用性。（約 30%） - 以 Terraform / IaC 管理與交付資料庫基礎設施，讓變更可版控、可重現、可審查。 - 設計並維運高可用架構，負責容量規劃、備份／還原與災難復原（DR）演練，保障資料不遺失、服務不中斷。 - 支援多區域／跨市場的資料庫架構，隨業務成長進行擴展與優化。 - 進行效能調校：索引設計、查詢優化、慢查詢分析等。（約 25%） - 與架構師及軟體工程師協作，將資料庫方案整合進應用架構。（約 20%） - 對負責的資料庫任務與功能負起 ownership，把事情確實完成到位。 - 建立監控與告警，主動發現並處理問題。 - 參與線上事故處理，進行除錯與 root cause 分析，提出有效解法。 - 探索並導入 AI／LLM 於資料庫維運（如智慧診斷、查詢優化建議、事故根因分析、維運自動化），把它變成團隊真正用得上的工具。 - 撰寫流程、設定與 runbook 文件，方便團隊參考與後續維護。 【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. - 具備紮實的資料庫維運實戰經驗（DBA / DBRE / 偏資料庫的 SRE 皆可）。 - 包含但不限於資工 / 資管 / 電機 / 資訊相關科系，或具備同等實務能力。 - 具備 MongoDB 維運經驗（架構不限）。 - 至少熟悉一種資料庫的維運與優化。 - 熟悉查詢優化與問題排查技巧。 - 熟悉 Linux / bash shell 操作。 - 能對任務負責、注重細節、把事情完成。 - 願意持續學習、能快速上手新技術。 【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. - 具備第二種資料庫的深入經驗，NewSQL 尤佳。 - Terraform / IaC 實務經驗。 - 具備 Kubernetes (K8s) 使用經驗尤佳。 - 具備雲端託管服務（managed services）的維運經驗尤佳。 - 對以 AI／LLM 輔助資料庫維運有興趣或實作經驗者尤佳。 - MongoDB Associate DBA 認證。 - 曾參與電商平台或高流量 SaaS 的建置與維運。 - 在快速成長的新創環境工作過。 【Traits we value】 - 細心（這是必備）：DBA 的小疏忽往往是大事故。 - 情緒穩定：面對線上事故能冷靜、有條理地處理。 - 好奇心與聯想力：對系統運作有興趣，能舉一反三、預想潛在風險。 - 主動溝通：在團隊中願意表達想法、提出意見。 - 凡事求證：遇到問題習慣回到官方文件找答案。 - 重視知識傳承：習慣把設定、決策與事故處理寫成文件，而不是只存在腦袋裡。
