Job Description

Project Overview

We are seeking an experienced Java performance instructor to deliver a 3-day, hands-on training program (7 hours/day, 21 hours total) focused on JVM, garbage collection (GC), and code-level performance optimization.

The course should be practical and interactive, with live labs and guided exercises that teach participants to measure, diagnose, and optimize Java applications.

Target Audience

  • Intermediate to advanced Java developers
  • Engineers responsible for troubleshooting and optimizing JVM-based services
  • Teams aiming to improve application performance, reduce latency, and optimize memory usage

Training Objectives

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

  • Apply a structured performance methodology: measure → isolate → verify → iterate
  • Understand JVM fundamentals, including memory models and JIT compilation effects
  • Diagnose GC and memory issues and select appropriate GC strategies
  • Use modern monitoring and profiling tools to identify performance bottlenecks
  • Design and interpret microbenchmarks correctly, avoiding common pitfalls
  • Apply JVM tuning and memory optimization techniques confidently

Trainer Responsibilities

  • Deliver live, interactive instruction with strong hands-on labs, guided debugging, and Q&A
  • Provide lab environment setup instructions (local setup or pre-packaged VM)
  • Share training materials: slides, notes, and lab files
  • Include real-world troubleshooting patterns and actionable takeaways for practical application
  • Provide a post-training summary with key points and recommended next steps

Required Expertise

  • Extensive Java performance engineering experience (JVM, GC, profiling, benchmarking)
  • Hands-on experience with tools such as:
    • Java Flight Recorder (JFR) & Java Mission Control (JMC)
    • Profilers: VisualVM, async-profiler, YourKit, JProfiler, etc.
    • JMH microbenchmarking
  • Ability to explain complex performance concepts clearly to working developers
  • Experience troubleshooting live JVM performance issues

Nice to Have

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

Engagement Details

Training Style: Interactive, lab-heavy, focused on practical skills

Duration: 3 consecutive days, 7 hours/day (21 total hours)

Delivery: Remote live (unless specified otherwise)
