What You'll Do- Build features, integrate APIs and fix issues in our Go and PHP/Swoole projects.
- With guidance from senior engineers, read code, investigate logs, write tests, take part in code reviews and deliver tasks on schedule.
- Work with product, QA and engineering to clarify requirements, share progress and raise issues, and write technical notes where needed.
Requirements- Programming fundamentals: solid grasp of at least one backend language; able to build a small feature and explain how it works. Go or PHP preferred, but you don't need to know both. Coursework, personal projects and internships all count.
- Backend fundamentals: understand the basics of HTTP, APIs, JSON, databases, caching and message queues; able to write basic SQL, use Git and track down problems from logs.
- Learning and collaboration: you read documentation, test things hands-on and ask specific questions; you share progress and blockers proactively, and take code review feedback on board.
- Language: able to clarify requirements, discuss technical topics and write progress updates in Mandarin Chinese with our China-based engineering team; able to read English technical documentation and error messages (tools are fine).
- AI tools: willing to use company-provided Codex and Claude Code in your work; able to understand, review and test the code you submit, and follow our data security rules. No prior experience with specific AI tools required.
Nice to Have- Project experience with Go, PHP/Swoole, Shopify apps or third-party API integrations.
- Experience with MySQL 8.x, Redis or RabbitMQ, or exposure to AWS, Linux or Docker. Production operations and performance tuning experience is not required.
