Description

You will own performance testing, profiling, and optimization for scalable Java-based distributed systems.

This role is on-site.

Responsibilities

  • Design and execute performance tests (load, stress, soak, spike, capacity) using Apache JMeter, building reusable test plans and data strategies.
  • Instrument and analyze end-to-end system performance with Dynatrace, tracing hotspots across services, JVM, databases, caches, and external dependencies.
  • Engineer for scalability and resiliency by profiling bottlenecks, optimizing code paths, and tuning JVM/GC, threads, DB queries, and connection pools.
  • Automate performance pipelines by integrating tests into CI/CD (GitHub Actions, Jenkins, GitLab CI) with pass/fail gates based on defined thresholds.
  • Develop and maintain event-driven microservices using Java EE, Spring Boot, and Apache Kafka, ensuring secure coding and domain-driven design.

Required Skills

  • 6–8+ years of full stack development experience with a strong focus on Java and backend engineering.
  • Proficiency with Java EE, Spring Boot, Spring MVC, and RESTful API development.
  • Hands-on experience designing, developing, and operating event-driven systems using Apache Kafka.
  • Experience building scalable microservices and distributed systems with a solid understanding of domain-driven design.
  • Knowledge of CI/CD pipelines including Jenkins, GitHub Actions, or GitLab CI.
  • Exposure to Docker, Kubernetes, and cloud platforms such as AWS or Azure.

Preferred Skills

  • Experience with APM tools like Dynatrace for performance analysis.
  • Strong communication and collaboration skills in Agile environments (Scrum/Kanban).
