Senior Performance Engineer

About the Role

Seeking a Senior Performance Engineer to join R&D  and drive end-to-end performance optimization. This role focuses on identifying, analyzing, and resolving application performance bottlenecks to increase resiliency, scalability, and stability across distributed systems.In addition to driving end-to-end performance optimization, take ownership of performance within the value stream by guiding development teams and fostering continuous improvement in support of Backbase R&D’s 'Performance by Design' principle.

Key Responsibilities

• Drive performance within the value stream by serving as the go-to expert for all performance-related matters, providing guidance to development teams and taking full ownership of performance outcomes.
• Be an active member of the performance guild 
• Develop and execute performance test strategies targeting critical application paths and infrastructure layers.
• Design and maintain load testing scenarios to simulate production-like conditions using tools such as Gatling, JMeter and K6
• Analyze system behavior under load, isolate latency sources, and drive optimization efforts at application and platform levels.
• Partner with SRE, infrastructure, and observability teams to build performance dashboards and proactive alerting mechanisms.
• Integrate performance testing in CI/CD pipelines to enforce baselines and detect regressions.
• Perform root cause analysis of incidents and contribute to long-term remediation strategies.
• Validate scalability and throughput improvements following system changes or architectural redesigns.
• Collaborate with development teams to enforce performance-conscious coding practices and architectural patterns.
  
  

Required Qualifications

• Strong experience in Java application performance tuning.
• Multiple years of software quality engineer experience with Java in microservice environments
• Deep understanding of JVM performance metrics and GC tuning.
• Hands-on experience with distributed systems and microservices performance diagnostics.
• Experience with performance tools like Gatling, JMeter, Grafana K6 and CI/CD tools such as Github Actions
• Experience working in containerized environments (Docker, Kubernetes).
• Skilled in metrics and observability tooling (e.g., Prometheus, Grafana, OpenTelemetry).
• Strong analytical skills for interpreting performance data and generating actionable insights.
  
  

Preferred Qualifications

• 5+ years in performance engineering or similar roles in high-throughput systems.
• Exposure to chaos engineering principles as they intersect with performance testing.
• Experience in financial systems or similar latency-sensitive domains.
• Familiarity with cloud-native performance challenges (preferably Azure).
• Understanding of load balancers, caches, and messaging systems performance impact.
• Experience with network-level performance tuning and protocol-level optimizations.
• Experience with Spring framework and tuning JVM
