3What this role really is

An Associate Performance Engineer runs performance tests on software and gathers data to see how systems cope under load. The work involves running tests that others have designed, collecting results, and helping spot slow systems before they cause problems.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

Load Testing Frameworks (e.g., Gatling, Apache JMeter) Basic

Executing existing test scripts, making minor parameter changes (e.g., changing endpoints or test data files), and running tests as instructed. You'll be comfortable with the command line or GUI to start and stop tests.

APM & Observability (e.g., Dynatrace, Datadog, New Relic) Basic

Navigating pre-built dashboards to view basic metrics like CPU usage, memory consumption, and application response times for specific services during a test run. You'll be able to identify obvious spikes or drops.

Infrastructure Monitoring (e.g., Prometheus & Grafana) Basic

Viewing and understanding existing Grafana dashboards to check system health (e.g., server CPU, disk I/O) during tests. You might perform simple PromQL queries to check a specific metric if guided.

Log Aggregation (e.g., ELK Stack, Splunk, Loki) Basic

Using Kibana or Splunk to search for specific errors, warnings, or transaction IDs within logs to help troubleshoot issues identified during testing. You'll be able to apply basic filters.

Frontend Performance Tools (e.g., Lighthouse, WebPageTest) Basic

Running Lighthouse audits on web pages and understanding the top-level scores (Performance, Accessibility). You'll be able to identify obvious issues like very large images or slow loading resources.

Version Control (e.g., Git) Basic

Cloning repositories, pulling the latest changes, and committing your own minor script modifications or documentation updates. You'll be comfortable with basic Git commands.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Test Script Modification No independent modifications. Propose minor changes (e.g., updating an endpoint) to manager for review and approval. Routine modifications to existing scripts (e.g., data correlation, parameterisation) within established frameworks. Major changes require peer review. Design and implement complex test scenarios from scratch. Approve modifications made by junior engineers. Decide on framework usage.
Performance Issue Diagnosis Identify obvious symptoms (e.g., high error rate, slow response time). Escalate to manager with collected data. Independently diagnose common bottlenecks (e.g., database queries, network latency) using standard tools. Propose initial solutions. Perform deep-dive root cause analysis for complex, multi-system issues. Recommend architectural changes or code fixes.
Tool Selection Use pre-selected tools as instructed. Research and propose alternative tools for specific problems, with manager approval. Evaluate, select, and champion new performance engineering tools for the team or department.
Test Environment Configuration Follow detailed instructions to configure existing test environments. Independently configure and troubleshoot standard test environments. Propose minor improvements to setup scripts. Design and automate the provisioning of complex, production-like test environments.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Test Execution Accuracy
Running performance tests exactly as specified in the test plan, ensuring all parameters and configurations are correct.
Target · 99% accuracy in test setup and execution

If a test plan says to run a Gatling script with 500 concurrent users for 30 minutes, you'll set it up and run it precisely that way, without missing a parameter or misconfiguring the environment. A mistake, like running it for 20 minutes instead, would count against this.

Defect Validity Rate
The percentage of performance defects you log that are accepted by the development team as valid and reproducible issues.
Target · >90% of logged defects accepted

You spot a high p99 latency on a specific API endpoint during a test, log it with clear steps and evidence. If the dev team confirms it's a real bug, that's a valid defect. If they can't reproduce it or say it's 'expected behaviour', it's not. We want you to find real issues, not ghost problems.

Report Timeliness
Delivering standardised test summary reports within the agreed timeframe after a test run is completed.
Target · Reports delivered within 2 business hours of test completion

You finish a load test at 3 PM on a Tuesday. The expectation is that the basic summary report, using our standard template, is in the hands of your manager by 5 PM that same day, or by 10 AM on Wednesday if it was a late finish.

Monitoring Setup Adherence
Correctly configuring basic monitoring dashboards and alerts as per instructions for new test environments.
Target · 100% adherence to monitoring setup guides

When a new test environment is spun up, you're given a checklist for setting up a basic Grafana dashboard and a few Prometheus alerts. You'll need to follow that guide exactly, ensuring all specified metrics are visible and alerts are correctly configured. Missing a key metric would be a miss here.

Learning & Application
Actively seeking to understand new tools, concepts, and methodologies, and applying that learning in your daily tasks.
  • Asking thoughtful questions during code reviews or team meetings
  • successfully applying a new command you learned
  • taking notes during training sessions and referring to them
  • sharing a small 'aha!' moment with the team after figuring something out.
Adherence to Standards
Consistently following established processes, naming conventions, and documentation guidelines.
  • Your test scripts and reports consistently use the agreed-upon naming conventions
  • you update documentation sections when you complete a task
  • your work is easily understood by others because it follows our internal standards.
Proactive Questioning
Asking clarifying questions when instructions aren't clear, rather than making assumptions that could lead to errors.
  • You'll say, 'Just to be clear, when you say 'high load', do you mean 1000 users or 10,000?' or 'I'm not sure which data set to use here, could you point me to the right one?' before starting a task
  • you raise potential issues or ambiguities early on.
Team Collaboration
Working effectively with your immediate team, asking for help when stuck, and offering support where you can.
  • You respond quickly to team messages
  • you actively participate in stand-ups
  • you're happy to pair with a colleague to learn or help out
  • you're not afraid to admit you're stuck and ask for guidance.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Learning New Technical Skills

You'll be excited to pick up new scripting languages, learn how to navigate different monitoring dashboards, and understand the ins and outs of various profiling tools. Every day will bring a chance to add a new tool to your belt.

Spending your lunch break watching a tutorial on PromQL queries or asking a senior engineer how eBPF works, then trying it out on a non-production system.

Solving Puzzles

You'll enjoy the challenge of figuring out why a system is slow. It's like being a detective, piecing together clues from logs, metrics, and traces to uncover the culprit. Even at this level, you'll be contributing to that investigation.

Being given a test result showing high CPU usage and then, with guidance, digging into Grafana to see if you can spot any correlating spikes in other metrics.

Contributing to Product Quality

You'll feel a sense of satisfaction knowing that your work directly helps ensure our products are fast and reliable for users. You're a key part of preventing those frustrating 'spinning wheel' moments.

Seeing a feature you tested go live and knowing your efforts helped ensure it performs well, avoiding customer complaints about slowness.

What frustrates people
  • Being told to 'just run a quick test' when you know it takes hours of setup.
  • Waiting for test environments to be provisioned or fixed, which can delay your work.
  • Dealing with messy or incomplete test data that makes your job harder.
  • Having to explain basic performance concepts multiple times to different people.
  • Finding a performance issue only for it to be deprioritised because a new feature is 'more important'.
What this role does not give you
  • Immediate high-level strategic influence or decision-making authority.
  • Full autonomy to choose your own projects or tools without guidance.
  • A guarantee that every performance issue you find will be fixed immediately.
  • A role focused purely on coding or feature development.

8Who you work with

Your work ensures that the software we build can actually handle the load our customers throw at it. If you miss something, it could mean slow response times, errors, or even crashes for our users. On the flip side, by doing your job well, you directly contribute to a smooth, reliable experience for everyone who uses our products, which ultimately keeps our customers happy and our business running.

Inside the business
  • Your direct manager (Performance Engineer)
  • The wider Performance Engineering team
  • Junior Software Developers (the ones whose code you're testing)
  • QA Engineers (who focus on functional testing)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • A foundational understanding of computer science principles, perhaps from a degree or self-study.
  • Basic scripting skills in at least one language (e.g., Python, Java, JavaScript) to understand and make minor edits to test scripts.
  • Familiarity with command-line interfaces (CLI) and basic Linux commands.
  • A genuine interest in performance, scalability, and how software systems behave under load.
  • The ability to follow detailed instructions and a willingness to learn from feedback.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Load Testing Scripting

You'll move beyond just executing. As systems become more complex, you'll need to create more realistic and dynamic test scenarios that mimic real user behaviour, not just simple 'hit this endpoint'.

Dynamic Data Correlation · Parameterisation · Custom Logic & Assertions · Distributed Load Generation

  • This week: Ask your manager for an existing complex script and try to understand its flow.
  • This month: Pick one feature (e.g., data correlation) and try to implement it in a simple test script.
  • Month 2: Work with a senior engineer to refactor a small part of an existing script to make it more robust.
  • Month 3: Propose a minor improvement to a test script that you've been running regularly.

Quick win: Try to identify a repetitive part of an existing script and think about how you could make it more dynamic with simple parameterisation.

Deep-Dive APM Analysis

As you gain experience, you won't just look at dashboards. You'll need to trace transactions, understand code-level performance, and build custom views to get to the real root cause of issues.

Distributed Tracing · Code-Level Profiling (APM) · Custom Dashboard Creation · Alerting Configuration

  • This week: Spend time exploring the 'trace' view in our APM tool for a known slow transaction.
  • This month: Try to build a very simple custom dashboard in Datadog or Dynatrace with 2-3 key metrics.
  • Month 2: Ask a developer to walk you through how their code shows up in the APM tool.
  • Month 3: Propose a new alert based on a performance issue you've observed during testing.

Quick win: Just clicking around the APM tool beyond the main dashboard and exploring different views will be a great start.

11Staying current once you are in

What people here do to keep up
  • Participating in online courses or tutorials on performance testing tools (e.g., free JMeter courses, Gatling documentation).
  • Attending local tech meetups or webinars focused on software performance or observability.
  • Contributing to open-source projects, especially those related to testing or monitoring.
  • Reading blogs and articles from industry experts on performance engineering best practices.
  • Building small personal projects and intentionally trying to optimise their performance.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, some parts of performance engineering can feel a bit repetitive, especially when you're starting out. But what if you could offload some of that grunt work to AI? Imagine spending less time on manual tasks and more time actually learning and digging into the interesting problems.

We're big believers in using AI to make our lives easier, not replace us. For an Associate Performance Engineer, that means AI can become your personal assistant, helping you with everything from understanding complex logs to drafting your reports. It's about getting to the 'aha!' moments faster.

Automated Script Generation (Basic)

AI can analyse simple traffic logs and help draft the basic structure of a Gatling or JMeter script for you. You'll still need to review and refine it, but it's a massive head start compared to writing from scratch. Think of it as having a coding buddy.

Log Analysis Assistant

Instead of manually sifting through thousands of log lines, you can feed chunks of logs into an AI tool. It'll help you quickly identify error patterns, spot unusual activity, or even summarise what happened during a specific time window, making your troubleshooting much faster.

Instant Knowledge Retrieval

Got a question about a specific tool, an old incident, or a team process? Our internal AI chatbot, trained on our documentation, can give you instant answers. No more endless searching through Confluence or Slack archives – just ask and get a concise summary.

Drafting Test Summaries

After a test run, AI can take your raw data (like a CSV of results or a screenshot of a dashboard) and help you draft an initial summary report. It'll pull out key metrics and even suggest initial observations, giving you a solid starting point to refine and add your insights.
