Performance Testing Architect

Role

Accelerate your development and exposure to high performance applications and cloud infrastructure. Join Faptic Technology (remote), a fast-growing scale-up organization with an ambition to be recognized as one of the leading technology companies in Romania.

Our global client base needs builders: engineers and developers who love technology, have deep expertise in software and cloud technologies, and importantly, have a passion for culture and customers.

• We obsess about our customers
• We build outstanding technical solutions
• We create an awesome culture
• We accelerate learning and careers

As a Performance Testing Architect, you will be part of a high-performing team dedicated to ensuring the scalability and reliability of our client's trading platforms. In this role, you will focus on performance testing and optimization in a high-throughput, low-latency environment while working closely with development teams to identify and resolve performance bottlenecks.

You will leverage K6, JavaScript/TypeScript, and containerized environments to develop and execute performance tests. Your expertise in API performance testing (REST, GraphQL), JVM tuning, and cloud-based performance strategies will be essential in optimizing system performance. Our team is committed to helping you reach your full potential while working with cutting-edge technologies on exciting and challenging projects.

Your activities will include:

• Lead the performance testing strategy for our client's trading platforms, ensuring system resilience and scalability
• Develop and maintain K6 scripts in JavaScript/TypeScript, implementing data-driven testing approaches
• Optimize API performance for REST and GraphQL endpoints, covering rate limiting, caching strategies, and load balancing
• Monitor and analyze system performance using Grafana, providing insights and recommendations
• Collaborate with development teams to identify and resolve performance bottlenecks
• Ensure best practices in Spring Boot applications, microservices architectures, resource management, and JVM tuning
• Integrate performance tests into GitLab CI/CD pipelines to enable continuous performance validation
  

Requirements

• BSc/MSc in Computer Science or related field
• Minimum 5 years’ hands-on experience in QA testing
• Minimum 5 years’ experience in performance testing using tools such as K6 or Gatling
• Proficiency in JavaScript/TypeScript for developing performance test scripts
• Hands-on experience in API performance testing (REST, GraphQL), including rate limiting and caching strategies
• Knowledge of Spring Boot and microservices architectures
• Experience with Kubernetes and Docker, including HPA, resource limits, and debugging latency issues
• Proven best practice with monitoring tools such as Prometheus and Grafana for performance analysis
• Experience in building CI/CD pipelines using GitLab CI or Jenkins

The following will be considered an advantage:

• Advanced knowledge of gRPC and WebSockets performance testing, including HTTP/2 optimizations
• Java performance optimization expertise, including JVM tuning and database query optimization
• Experience with cloud-based performance strategies, including service mesh solutions (Istio, Linkerd) and distributed tracing (Jaeger, OpenTelemetry)
