About the Role

As a Java Performance Architect, you will play a pivotal role in diagnosing, designing, and optimizing complex enterprise Java environments.

This position has a particular focus on Java application and system performance optimization. We are looking for someone with deep expertise in JVM behaviour and enterprise application performance who can identify bottlenecks across the application, middleware, database, operating-system, and infrastructure layers.

You will investigate complex production performance issues, identify root causes, and architect practical solutions that improve application responsiveness, transaction throughput, scalability, resource utilization, reliability, and overall system efficiency.

You will also work directly with clients and internal teams to lead technical discovery, communicate findings, recommend architectural improvements, and support implementation through completion.

What You Will Be Doing

• Lead the investigation and resolution of complex Java performance issues across the full technology stack, including application code, JVM, middleware, databases, operating systems, infrastructure, and external dependencies.
• Analyze JVM and application behaviour including memory utilization, garbage collection, threading, concurrency, CPU usage, connection management, application-server configuration, latency, and throughput.
• Use profiling, observability, thread dumps, heap dumps, database analysis, and other diagnostic techniques to identify root causes and recommend improvements to scalability, stability, and resource utilization.
• Evaluate application architecture and design scalable, maintainable, and high-performing Java solutions across traditional, distributed, cloud, and modernized environments.
• Lead technical discovery sessions, architecture workshops, performance assessments, and solution-design discussions with clients and internal teams.
• Produce and present technical findings, architecture recommendations, root-cause analyses, remediation plans, and implementation roadmaps while serving as a senior technical escalation point throughout delivery.
