Senior Performance QA Engineer
Requirements and responsibilities
Readable role content extracted into sections for faster review.
Responsibilities
- Translate business and technical requirements into concrete performance test plans covering load, stress, scalability, and reliability scenarios.
- Analyze Java application performance at both architecture and code levels — identify bottlenecks, diagnose root causes, and drive optimization end-to-end.
- Design and implement architecture-level and code-level optimizations to enhance system throughput and stability.
- Work closely with DevOps to ensure production-level high availability across distributed systems.
- Independently troubleshoot real-time performance issues and deliver solutions with full ownership.
- Develop internal tools for automated performance monitoring, testing, and issue analysis.
- Review and validate AI-generated code for correctness and performance risks — leverage your engineering expertise to assess whether AI-assisted code meets production quality standards.
Requirements
- Strong ability to identify performance bottlenecks at system, service, and code levels, including deep proficiency in Java application performance analysis and JVM-level tuning (GC optimization, heap/thread analysis, profiling).
- Hands-on experience troubleshooting microservice performance issues in production environments.
- Practical experience with performance engineering tools such as K6 or JMeter.
- Proficiency with relational and NoSQL databases (MySQL, MongoDB), including query optimization and slow-query analysis.
- Familiarity with performance analysis for middleware such as Kafka, Redis, RabbitMQ.
- Experience with containerization and orchestration (Docker, Kubernetes).
- Solid Linux skills — command-line and system-level troubleshooting.
- Programming language: Java (mandatory). Strong engineering instincts to evaluate code quality and performance implications.
- Strong passion for building systems that excel in performance, scalability, and reliability.
- We also welcome:
- Java backend engineers looking to transition into QA — if you have deep Java development experience and a passion for performance engineering, this role is a great fit.
- New graduates with demonstrated Java and performance testing foundation.
Nice to haves
- Experience at enterprise-grade distributed systems environments.
- Hands-on experience with AI-assisted development tools (e.g., GitHub Copilot, Cursor, Claude Code) and ability to critically assess AI-generated code for performance and correctness.
- Experience with public cloud platforms (AWS, Azure, GCP, AliCloud).
- Hands-on experience setting up monitoring/observability stacks (Prometheus, Grafana).
- Linux kernel or OS-level performance analysis skills.
- Experience triaging and resolving production performance incidents.
- Ability to leverage APM tools (e.g., SkyWalking, Pinpoint, Jaeger) for performance troubleshooting.
- Rust programming experience.
- Experience working within distributed, remote teams.
