Performance Engineer

Join a high-impact Performance Engineering team focused on optimizing a Java-based trading platform at scale. As a Senior Performance Engineer, you will independently drive performance, scalability, and resiliency initiatives for mission-critical financial systems. You’ll dive deep into code, analyze complex systems, and collaborate with cross-functional teams to push the limits of latency and reliability. This is an ideal opportunity for engineers passionate about solving tough performance challenges and making a measurable impact in the fintech domain., Plan, execute, and deliver performance, scalability, and resiliency validations for Java trading systems

• Investigate architecture, business flows, dependencies, and production behaviors to inform performance initiatives
• Define requirements, workloads, and acceptance criteria in partnership with development and QA teams
• Build and maintain performance test scripts, workload generators, automation frameworks, and mock services
• Perform rigorous load, stress, endurance, failover, recovery, degradation, and resiliency testing
• Deeply analyze Java source code, JVM internals, system resources, databases, and network metrics to identify bottlenecks
• Recommend and validate technical improvements for code, configuration, infrastructure, design, and capacity
• Maintain dashboards, diagnostic tools, runbooks, and workload libraries to support ongoing performance monitoring
• Leverage automation and AI tools to enhance scripting, diagnostics, and documentation
• Clearly communicate findings, risks, and recommendations to stakeholders

Bachelor’s degree in Computer Science or Engineering

• 5+ years in performance engineering, scalability, or production performance analysis
• 2+ years hands-on Java development with deep understanding of JVM internals, concurrency, multithreading, memory, and garbage collection
• Expertise in troubleshooting, profiling, and diagnosing Java and system-level issues (using logs, dumps, profilers, observability tools)
• Proficient in workload automation using Java, Scala, Python, shell scripting, JMeter, or Gatling
• Strong knowledge of Linux, databases, application servers, caching, connection pools, distributed systems, and networks
• Experience with Splunk, Grafana, and JVM troubleshooting

Preferred Skills

• Real-time financial or trading system experience
• Familiarity with Google Cloud, Kubernetes, or Docker
• Experience with AI-assisted analysis, LLM tools, or intelligent automation
• Exposure to AI tools within Visual Studio or IntelliJ IDEA, This is not a traditional Java Developer role but they do need someone who can read and analyze Java source code understand JVM internals and make code-level recommendations to improve performance The main focus is performance testing troubleshooting bottlenecks scalability and system resiliency not primarily building new application features Ideally look for a Performance Engineer or Java Performance Engineer who has hands-on coding experience

Career growth through hands-on performance engineering in a high-demand fintech environment

• Opportunity to convert to full-time based on performance
• Hybrid work model: Enjoy a collaborative onsite environment with flexibility for remote work
• Be at the forefront of leveraging AI and automation in performance engineering
