Job Description

Position: Instructor – Java Performance Tuning
Engagement: Contract (3 Days / 21 Hours Total)
Delivery Mode: Remote, Live Instructor-Led

Project Overview

We are seeking an experienced Java Performance Tuning Instructor to deliver a highly practical 3-day training program (7 hours per day). The course should focus on real-world performance analysis and optimization techniques for Java applications, covering the JVM, Garbage Collection (GC), and application code performance.

The training must include hands-on labs, live demonstrations, and practical debugging exercises to help participants understand how to measure, diagnose, and improve Java application performance effectively.

Target Audience

  • Intermediate to advanced Java developers
  • Engineers responsible for diagnosing and resolving performance issues in JVM-based applications and services

Training Objectives

By the end of the training, participants should be able to:

  • Apply a structured performance methodology: Measure → Isolate → Verify → Iterate
  • Understand JVM performance fundamentals, including memory model and JIT compilation impact
  • Diagnose memory and garbage collection issues
  • Select appropriate GC strategies for different workloads
  • Use modern monitoring and profiling tools to identify performance bottlenecks
  • Design reliable microbenchmarks and avoid common benchmarking mistakes
  • Implement JVM tuning and memory optimization techniques with confidence

Trainer Responsibilities

  • Deliver live, interactive instruction with strong hands-on lab sessions
  • Provide a runnable lab environment setup guide (local or packaged)
  • Share training slides, notes, and lab materials
  • Demonstrate real-world troubleshooting scenarios
  • Provide actionable insights participants can apply immediately
  • Deliver a short post-training summary with key takeaways and recommendations

Required Expertise

  • Strong experience in Java performance engineering
  • Deep understanding of:
    • JVM internals
    • Garbage Collection tuning
    • Profiling and benchmarking
  • Hands-on experience with tools such as:
    • Java Flight Recorder (JFR)
    • Java Mission Control (JMC)
    • Profilers like VisualVM, async-profiler, YourKit, or JProfiler
    • JMH for microbenchmarking
  • Ability to explain complex concepts clearly and troubleshoot issues live

Nice to Have

  • Experience tuning low-latency or high-throughput systems
  • Familiarity with tail latency analysis
  • Experience in production performance troubleshooting
  • Knowledge of performance testing strategies and experiment design

Engagement Details

  • Duration: 3 consecutive days (21 hours total)
  • Format: Remote live training
  • Style: Interactive, lab-heavy, practical focus
