关于项目 / About the project Oakcare 是一家新加坡养老护理平台。我们的 AI 系统基于 Google ADK + Gemini 2.5（GCP）。需要一位平台工程师搭建可观测性、测试和 CI/CD 基础设施，让团队能够可靠地迭代发布。 Oakcare is a Singapore-based platform helping families hire trusted live-in eldercare workers. Our AI systems run on Google ADK + Gemini 2.5 on GCP. We need a platform engineer to build the observability, testing, and CI/CD foundations that allow us to ship reliably as we scale. 你将负责 / What you'll work on 搭建集中式可观测性——结构化日志、关联 ID、错误追踪（Sentry/Datadog）、LLM 调用追踪（LangSmith/Langfuse）/ Set up centralized observability — structured logging, correlation IDs, error tracking, LLM call tracing 从零搭建 CI/CD 管道（GitHub Actions）——每次 PR 自动测试，失败阻断合并 / Build CI/CD pipeline from scratch (GitHub Actions) — auto tests on every PR, block merges on failure 编写单元测试和集成测试——数据解析、LLM 输出校验、golden file 测试 / Write unit and integration tests — data parsing, LLM output validation, golden file tests 审计和加固 GCP 基础设施——IAM、Cloud Run、密钥管理、监控 Dashboard / Audit and harden GCP infrastructure — IAM, Cloud Run, secrets management, monitoring dashboards 将3个独立 repo 合并为 monorepo，共享工具类和测试夹具 / Consolidate 3 repos into a monorepo with shared utilities and test fixtures 修复数据 schema——存储出生日期而非固定年龄，确保时效字段正确重新计算 / Fix data schema — store DOB not fixed age, ensure time-sensitive fields recalculate correctly 技术要求 / Requirements 扎实的 Python，熟悉测试和工具链 / Strong Python — testing, tooling, scripting CI/CD 实战（GitHub Actions 或同类）/ CI/CD hands-on — GitHub Actions or equivalent GCP 实战——Cloud Run、Cloud Logging、Cloud Monitoring、IAM 可观测性工具经验——Sentry、Datadog、LangSmith 或 Langfuse 测试框架搭建经验（pytest、golden file） 加分：monorepo 经验、LLM 系统背景 / Bonus: monorepo experience, LLM system background 薪资 / Compensation：面议 / Negotiable — 项目制 / Project-based 申请时请附上你搭建过的 CI/CD 管道或测试套件的相关案例。 Please include examples of CI/CD pipelines or test suites you have built. 熟悉Python 做过自动测试平台和测试链路工具 熟悉大模型应用开发 可以，有兴趣
