Job Description

Project Overview
We are seeking an experienced Java performance instructor to deliver a 3-day, instructor-led training (7 hours/day, 21 hours total). The sessions should be highly practical and hands-on, teaching participants how to measure, diagnose, and optimize Java application performance at the JVM, GC, and code level.

Target Audience

  • Java developers (intermediate and above)
  • Engineers troubleshooting performance issues in JVM-based 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 (memory model, JIT compilation effects)
  • Diagnose GC and memory-related issues and select appropriate GC strategies
  • Use modern monitoring and profiling tools to identify bottlenecks
  • Design and interpret microbenchmarks correctly, avoiding common pitfalls
  • Apply JVM and memory tuning techniques with confidence

Trainer Responsibilities

  • Deliver live instruction with strong hands-on components (labs, guided debugging, Q&A)
  • Provide a runnable lab environment plan with setup instructions and prerequisites
  • Share training materials (slides, notes, lab files)
  • Include real-world troubleshooting patterns and “what to do Monday morning” guidance
  • Provide a short post-training summary with key takeaways and recommended next steps

Required Expertise

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

Nice to Have

  • Experience tuning low-latency services and interpreting tail latency
  • Experience with production performance triage (threading, contention, I/O bottlenecks)
  • Familiarity with performance testing approaches and test design

Engagement Details

  • Duration: 3 consecutive days (7 hours/day, 21 total hours)
  • Delivery: Remote live session (unless specified otherwise)
  • Style: Interactive, lab-heavy, focused on practical skills

To Apply
Please include:

  • Summary of your Java performance tuning experience (years, types of systems)
  • Tools you regularly use for JVM monitoring, profiling, and GC analysis
  • Any sample syllabus or materials you can share (sanitized is fine)
  • Your availability (time zone and possible delivery windows)
  • Proposed approach for labs (local setup vs pre-packaged environment)
