資料/後端工程師 Data / Backend Engineer (Mid Level / Senior Level)

【About the Role】
You’ll join a product-led, engineering-centric team focused on designing and scaling robust data engineering and backend systems. Our work spans high-volume data ingestion, complex data transformation (ETL/ELT), automated task orchestration (e.g., using Prefect), and cost-efficient cloud-native infrastructure.
We value the engineering discipline. Our workflow includes unit testing, API testing, and a well-defined Data/CI/CD pipeline. We also equip all developers with Claude code or Cursor to enhance development velocity and code quality.

【What You’ll Do】

• Design and implement robust, maintainable APIs and backend modules (primarily using FastAPI)
• Optimize data workflows, caching strategies, and asynchronous background jobs
• Design, implement, and maintain scalable ETL/ELT pipelines, leveraging tools like BigQuery for data warehousing and Prefect for workflow orchestration.
• Explore and integrate LLM technologies (e.g., Gemini API) to build intelligent, data-driven features for our commercial property platform.
• Write and maintain unit tests and API tests using Pytest, HTTPX, etc.
• Collaborate with product, frontend, and PI (Property Intelligence) team to transform business needs into backend systems

Build observability and Data/CI/CD pipelines to ensure reliability and traceability

【Tech Stack】

• Backend: Python 3.x, FastAPI / Flask
• Data Engineering: BigQuery (Data Warehouse), Prefect (Workflow Orchestration)
• Testing: Pytest, HTTPX, unittest, Testcontainers
• Databases: PostgreSQL, Redis
• Search & Analytics: Elasticsearch, BigQuery, optional integration with vector DBs
• Infrastructure: Docker, GCP (Cloud Run / GKE), GitHub Actions
• Observability: Grafana, Prometheus, Loki
• AI Tools: Claude Code, Cursor, LLM APIs (e.g., Gemini API)

【Team Culture & Values】

• Code Quality First: Test coverage and code reviews are non-negotiable
• AI-Accelerated: Claude and Cursor are integrated into daily workflows
• Modular Architecture: We prefer clean boundaries and loosely coupled systems
• Ownership Mentality: You’ll own problems end to end and have a voice in system design

【What We’re Looking For】

• 3+ years of Python backend development experience
• Strong grasp of RESTful APIs, database modeling (PostgreSQL)
• Experience with testing frameworks (Pytest preferred)
• Hands-on with Redis, async job queues, background task orchestration
• Comfortable with Git and modern CI/CD workflows
• Familiar with Docker and Unix/Linux environments

【Nice to Haves】

• Experience with GCP and Kubernetes (GKE, Cloud Run, Pub/Sub)
• Built ETL pipelines or scraping systems
• Comfortable using Claude, Cursor, or GitHub Copilot
• Familiarity with observability stacks (Prometheus, Grafana, Loki)
• Experience mentoring developers or performing code reviews
• Familiarity with frontend development (e.g., React frameworks) is a plus
