Job Description

Project Overview

We are seeking an experienced Java Performance Instructor to deliver a 3-day, live, instructor-led training focused on practical, hands-on skills. Participants will learn how to measure, diagnose, and optimize Java application performance at the JVM, GC, and code level.

  • Duration: 3 consecutive days, 7 hours per day (21 hours total)
  • Mode: Remote live instruction
  • Audience: Java developers (intermediate+), engineers troubleshooting JVM-based services

Training Objectives

By the end of this training, participants will be able to:

  • Apply a structured performance methodology: measure → isolate → verify → iterate
  • Understand JVM performance fundamentals, including memory model and JIT compilation effects
  • Diagnose GC and memory-related issues, selecting appropriate GC strategies
  • Use modern profiling and monitoring tools to identify bottlenecks
  • Design and interpret microbenchmarks effectively (avoiding common pitfalls)
  • Apply JVM and memory tuning techniques with confidence

Trainer Responsibilities

  • Deliver interactive, lab-heavy sessions with guided debugging and Q&A
  • Provide a runnable lab environment plan (setup instructions and prerequisites)
  • Share training materials (slides, notes, lab files)
  • Include real-world troubleshooting patterns and actionable guidance (“Monday morning tips”)
  • Provide a post-training summary: key takeaways and recommended next steps

Required Expertise

  • Strong Java performance engineering experience (JVM, GC, profiling, benchmarking)
  • Practical experience with tools such as:
    • Java Flight Recorder (JFR) & Mission Control (JMC)
    • Profilers: VisualVM, async-profiler, YourKit, JProfiler, etc.
    • JMH microbenchmarking
  • Ability to explain complex concepts clearly and troubleshoot live

Nice-to-Have Experience

  • Tuning low-latency services and interpreting tail latency
  • Production performance triage: threading, contention, I/O bottlenecks
  • Familiarity with performance testing approaches and test design

Engagement Details

  • Delivery: Remote, live, interactive sessions
  • Training Style: Lab-heavy, practical, interactive
  • Total Duration: 21 hours over 3 consecutive days

Application Requirements

To apply, please include:

Proposed approach for labs (local setup vs pre-packaged environment)

Summary of Java performance tuning experience (years, system types)

Tools regularly used for JVM monitoring, profiling, and GC analysis

Sample syllabus or materials (sanitized is acceptable)
