Senior Performance Engineer

At NiCE, we don’t limit our challenges. We challenge our limits. Always. We’re ambitious. We’re game changers. And we play to win. We set the highest standards and execute beyond them. And if you’re like us, we can offer you the ultimate career opportunity that will light a fire within you.

So, what’s the role all about?

We are seeking a highly skilled Senior Performance Engineer to lead the performance validation of our complex enterprise software product. This software handles massive transaction loads, operates across multiple operating systems and databases, and is deployable both on-premises and in the cloud. The ideal candidate will have strong expertise in performance testing, including workload modeling, test planning, execution, analysis, and reporting, with a focus on ensuring scalability, responsiveness, and stability under varying load conditions.

How will you make an impact?

Performance Testing:

• Performance Testing and Analysis
• Design and execute performance benchmarking, load testing, and stress testing strategies.
• Conduct performance tests to evaluate system behaviour under different load conditions (e.g., load testing, stress testing, scalability testing).
• Analyse and interpret performance test results, identify bottlenecks, and recommend solutions.
• Develop performance test plans, test cases, and execution strategies.
• Track performance metrics and trends over time to ensure consistency and stability of systems.
• Performance Benchmarking
• Perform benchmarking activities to understand and measure system performance against industry standards and best practices.
• Application Monitoring
• Continuously monitor the performance of applications in cloud-based pre-production environments.
• Utilize application performance management (APM) tools (e.g., Jprofiler, Open-source tools, etc.) to detect and troubleshoot performance issues.
• Implement observability solutions, leveraging tools like Prometheus, Grafana, New Relic, Dynatrace, or Datadog for real-time performance monitoring.
• Troubleshooting and Issue Resolution
• Investigate and resolve performance-related issues across multiple platforms (web, backend services).
• Work with teams to implement effective root cause analysis for performance failures.
• Identify, diagnose, and optimize performance bottlenecks across the entire technology stack (application, database, infrastructure, and cloud environments)
• Automation and Scripting
• Develop automated scripts and frameworks for creating complex financial data, load, and performance testing.
• Leverage automation tools (e.g., JMeter, LoadRunner, Gatling) to run performance tests and gather metrics.
• Develop and maintain performance test suites using industry-standard tools (JMeter, Gatling, LoadRunner, etc.).

• Reporting and Documentation

• Create detailed reports with analysis, recommendations, and action plans for performance improvements.
• Maintain thorough documentation of performance tests, results, and optimization strategies.

 Have you got what it takes?

Education:

• Bachelor’s or Master’s degree in Computer Science, Information Technology, Engineering, or a related field.

Qualifications - Essential:

• 5-7 years of hands-on experience in performance engineering for enterprise-grade applications
• Hands-on experience with performance testing tools (e.g., Apache JMeter, LoadRunner, Gatling, NeoLoad or similar).
• Expertise in analysing CPU, memory, disk, and network performance in distributed systems.
• Basic understanding of profiling and tuning JVM-based applications (Java, Scala, Kotlin) or other modern runtime environments.
• Strong understanding of multi-threading, concurrency, and memory management.
• Familiarity with CI/CD pipelines and integrating performance testing into DevOps workflows.
• Excellent analytical and problem-solving skills with a deep understanding of system design.

Qualifications - Preferred:

• Hands-on experience with database performance tuning (SQL query optimization, indexing, partitioning, caching, replication strategies).
• Experience with cloud-based performance optimization (AWS, Azure, or GCP) and containerized environments (Docker, Kubernetes).
• Experience with intelligent performance monitoring solutions
• Knowledge of event-driven architectures, Kafka, or messaging systems
• Previous experience optimizing serverless and microservices architectures
• Strong scripting skills in Python, Bash, Groovy or PowerShell for automation
• Familiarity with agile methodologies and DevOps practices
• Experience with infrastructure-as-code tools (e.g., Terraform, Ansible)
• Background in security performance testing
• In-depth knowledge of web technologies (HTTP, HTTPS, REST APIs) and application architectures

What’s in it for you?

• Work on a high-impact, high-scale enterprise software product.
• Collaborate with top engineering talent in a dynamic, innovative environment.
• Competitive salary, benefits, and opportunities for career growth.

If you are a performance-focused engineer who thrives in complex, high-scale environments, we’d love to hear from you!
