Job description

About the Role

We’re building a mobile-first information platform and are approaching production launch. We’re looking for a Senior Backend Software Engineer to co-own our backend architecture and ensure the system is scalable, reliable, and production-ready.

This role is ideal for someone who enjoys designing systems and running them in the real world — handling performance bottlenecks, debugging production issues, and improving reliability as usage grows.

You’ll work closely with a small team and have meaningful influence over architecture, infrastructure decisions, and engineering practices.

What You’ll Do

System Design & Scalability

  • Review and improve backend system architecture for scale and reliability
  • Identify and resolve performance bottlenecks across services, databases, and caches
  • Design data models and APIs that scale as traffic and usage grow
  • Improve caching strategies and consistency patterns

Database & Performance

  • Optimize MySQL schemas, queries, and indexing strategies
  • Analyze slow queries and improve transaction performance
  • Plan for read scaling (replicas, partitioning strategies, etc.)

Production Reliability & Operations

  • Improve observability: logging, metrics, tracing, dashboards, and alerts
  • Debug and resolve production issues, including intermittent and edge-case failures
  • Design systems with resilience in mind (timeouts, retries, circuit breakers)
  • Participate in on-call and incident response as needed

Release Safety & Engineering Discipline

  • Improve deployment safety (blue-green, canary, rollback strategies)
  • Design safe database migration and backward-compatible changes
  • Contribute to engineering best practices and post-incident improvements

Our Tech Stack

  • Backend: Java, Spring Boot
  • Infrastructure: AWS ECS (Fargate), ALB, CloudWatch
  • Database: MySQL (RDS)
  • Caching: AWS ElastiCache (Redis)
  • Client: React Native (mobile)
  • CI/CD: GitHub Actions

Experience with similar stacks is welcome; deep backend and system design fundamentals matter most.

What We’re Looking For

Required

  • 5+ years of backend engineering experience
  • Strong system design and distributed systems fundamentals
  • Experience building and operating production backend services
  • Solid understanding of relational databases and query optimization
  • Experience with cloud infrastructure (AWS preferred)
  • Ability to debug complex issues under real-world constraints
  • Fluent spoken Mandarin required; ability to participate in technical discussions and collaborate with Mandarin-speaking stakeholders.

Strong Plus

  • Experience with Spring Boot in high-traffic systems
  • Hands-on experience with MySQL performance tuning
  • Experience with caching systems
  • Familiarity with observability tools (metrics, tracing, logging)
  • Startup or small-team experience with high ownership
