- 英语能力：具备优秀的英语听说读写能力，能作为工作语言与新加坡、雅加达等海外国际化团队无缝沟通，协同推进项目。
- 工作经验：8 年以上软件开发经验，2 年以上高并发/高可用系统架构设计经验。有电商、OTA、社交平台等“用户增长”、“营销活动”、“广告/推荐系统”或“数据平台”背景者优先。
- 技术栈要求：精通 Java 及 Spring Boot 生态（或其它 JVM 体系），具备扎实的面向对象设计模式及高质量代码编写能力。
- 数据与中间件：熟练掌握 PostgreSQL/MySQL，具备丰富的底层优化经验；熟悉 Redis/Memcached 等缓存技术，以及大型消息队列（如 Kafka/RabbitMQ）在高并发增长场景下的应用。
- 加分项：具有 AWS 云服务、Docker/K8s 容器化、基础设施即代码（IaC）经验者优先；有大数据处理（Spark/Flink）或 A/B 测试系统开发经验者优先。
- 业务自驱力：对数据敏感，具备强烈的增长黑客（Growth Hacking）意识，乐于看自己的代码直接转化为业务GMV、用户留存等核心指标的增长。
岗位福利：
15薪+15天年假+12天带薪病假+wlb。
Responsibilities
- Design & Build Growth Infrastructure: Architect, develop, and maintain high-scale backend services driving user acquisition, referral, and retention (e.g., A/B testing platforms, coupon/voucher engines, referral systems, and personalized notification/push services).
- Optimize for High-Traffic Campaigns: Own the system performance, scalability, and resilience during peak traffic seasons (e.g., mega-sales, flash deals) across Southeast Asia by implementing robust rate-limiting, caching, and circuit-breaking strategies.
- Data-Driven Quick Iteration: Collaborate closely with Product Managers and Data Scientists to support rapid growth experimentation. Build efficient data integration pipelines and tracking backends to accelerate the hypothesis-testing lifecycle.
- Cross-Functional Collaboration: Partner with regional product, marketing, and operations teams across multiple countries to translate complex business growth hacks into sustainable, scalable technical solutions.
- Code & Architecture Excellence: Write clean, maintainable, and highly efficient code. Participate in architectural discussions to continually reduce the engineering cost of running new user experiments.
Requirements
- Bachelor’s degree in Computer Science, Engineering, or a related field.
- Professional English Proficiency: Excellent verbal and written communication skills, with the ability to collaborate smoothly with international teams across different regions (Singapore, Jakarta, etc.).
- Minimum 8 years of experience in backend development, with strong proficiency in Java, Spring Boot, or JVM-centric stacks.
- Growth/Marketing Background Preferred: Direct experience in User Growth, E-commerce Campaigns, Ad-Tech, Recommendation Systems, or MarTech pipelines is highly preferred.
- High-Concurrency Tech Stack: Deep understanding of relational databases (PostgreSQL/MySQL), NoSQL (MongoDB), and caching layers (Redis). Solid experience with message brokers (Kafka/RabbitMQ) for handling asynchronous events.
- Familiarity with Cloud Infrastructure (preferably AWS), Docker/Kubernetes containerization, and Infrastructure as Code (IaC) is a plus.
- Growth Mindset: Data-sensitive, outcome-oriented, and passionate about seeing how engineering efforts directly impact core business metrics like MAU, conversion rates, and ROI.
