4How you'll be judged

The scoreboard, honestly: the hard targets, how often each one is actually looked at, and the quiet human signals that never make it onto a dashboard.

Production Incident Reduction (Performance-Related)

Reducing the number of P1/P2 incidents directly attributable to performance issues within your area of ownership.

Target · Contribute to a 25% reduction in performance-related P1/P2 incidents annually.

After your analysis and recommendations, the checkout service saw a 30% drop in 'slow response' alerts over six months, preventing several potential outages.

Mentorship Success & Junior Engineer Progression

Successfully guiding and developing junior Performance Engineers, helping them grow into more independent roles.

Target · At least one mentored L2 engineer is ready for promotion to Senior within a 2-year period, with positive feedback from both the mentee and their manager.

Your consistent code reviews and guidance helped a junior engineer independently design and execute a complex load test for a new microservice, something they couldn't do six months prior.

Automation Efficiency & Manual Effort Reduction

Improving the efficiency of our performance testing processes by automating setup, execution, and reporting.

Target · Reduce manual effort for test setup and reporting by 40% for your workstreams through scripting and automation.

You built a script that automatically provisions test environments and ingests production-like data, cutting a 2-day manual setup down to 2 hours.

Performance Regression Rate

The percentage of new releases or features that introduce a measurable performance degradation in key metrics (e.g., p99 latency, error rates).

Target · Ensure the regression rate is below 5% for the services you cover.

For the past two quarters, only 1 out of 25 releases for the core API introduced a performance regression, which you quickly identified and helped resolve before it impacted many users.

Capacity Planning Accuracy

The accuracy of your predictions for future infrastructure needs based on performance data and business growth.

Target · Achieve a +/- 15% variance between predicted and actual infrastructure usage for your assigned systems.

You predicted a 15% CPU increase for the data processing service in Q4, and actual usage came in at 13%, meaning we avoided over-provisioning by £10K.

Technical Leadership & Mentorship

Being a trusted technical advisor and a go-to person for performance-related challenges, actively helping junior team members grow.

Junior engineers consistently seek your advice before escalating. You regularly provide constructive feedback in code reviews. You lead internal knowledge-sharing sessions or workshops on performance topics. Your insights are sought out during design discussions.

Proactive Problem Identification

Identifying and addressing potential performance bottlenecks or risks before they manifest as production issues.

You present architectural recommendations that prevent future scalability issues. You spot subtle trends in monitoring data that others miss, leading to preventative action. You're often the first to raise concerns about a new feature's potential performance impact.

Cross-Team Collaboration & Influence

Effectively working with development, product, and operations teams to embed performance considerations throughout the software development lifecycle.

Development teams actively involve you in early design discussions. Product managers consult you on setting realistic performance budgets. You successfully advocate for performance-related tasks to be prioritised in sprint planning. You're seen as a bridge between teams, not just a tester.

Quality of Root Cause Analysis (RCA)

Conducting thorough, evidence-based RCAs for performance incidents, leading to clear, actionable recommendations.

Your RCAs are detailed, well-documented, and consistently identify the true underlying cause, not just symptoms. Your recommendations are adopted and demonstrably prevent recurrence. You can explain complex technical issues clearly to non-technical audiences.

5Would you like it

The honest version. What people enjoy, and what grinds them down.

What people enjoy

Solving Complex Technical Puzzles

You'll spend hours, sometimes days, deep-diving into logs, metrics, and traces, trying to uncover the subtle interaction causing a performance bottleneck. This isn't just about fixing; it's about understanding the 'why'.

You successfully traced a 500ms latency spike in the API to a specific database query plan regression that only happened under certain load conditions, a puzzle no one else could crack.

Continuous Learning and Mastery

The tech stack is always evolving, and you're always learning. You'll be experimenting with new profiling tools, reading up on the latest cloud optimisation techniques, or diving into the internals of a new framework to understand its performance characteristics.

You took the initiative to learn eBPF, and now you're using it to get incredibly granular insights into kernel-level performance issues that traditional profilers miss.

Making a Tangible Impact on System Reliability

Your work directly prevents outages, improves user experience, and helps save infrastructure costs. You'll see the direct results of your efforts in faster applications and fewer production incidents.

Your recommendations for optimising the caching layer led to a 20% reduction in database load and a noticeable improvement in page load times for our most critical user flows.

What frustrates people

The 'It works on my machine' defence: Spending hours proving a performance defect exists, only to have it dismissed by a developer who can't reproduce it on their overpowered, idle laptop.
Testing in unrealistic environments: Being forced to sign off on a release after testing on a 'quarter-scale' staging environment, knowing full well the results aren't representative of production reality.
The last-minute 'performance blessing': Being pulled in 48 hours before a major launch to 'quickly validate' performance, with absolutely no time to fix any identified issues, effectively making you a scapegoat.
The Observer Effect: The act of attaching a detailed profiler to diagnose an issue subtly changes the system's behaviour, sending you on a wild goose chase for a problem that only exists when you're looking for it.
Performance as a feature... for next quarter: Constantly advocating for performance improvements that get perpetually de-prioritised in favour of new features, until an outage forces everyone to pay attention.
'Can you just run a quick test?': A request from management that completely ignores the days of effort required to configure the environment, prepare test data, and write meaningful scripts for a valid test.

What this role does not give you

A predictable, unchanging daily routine.
Guaranteed implementation of every single performance recommendation you make.
A quiet, isolated environment where you don't need to interact with other teams.
The chance to avoid deep technical dives into unfamiliar codebases or systems.

6Who you work with

This role directly impacts our customer satisfaction by ensuring our applications are consistently fast and responsive. You'll also play a crucial part in reducing operational costs by identifying inefficiencies and preventing performance-related incidents. Ultimately, your work helps us maintain our reputation for reliable, high-performing software.

Inside the business

Development Teams (for implementing optimisations)
Product Managers (for understanding feature impact and setting performance budgets)
Operations/SRE Teams (for production monitoring and incident response)
QA Leads (for integrating performance testing into the overall quality strategy)
Solution Architects (for reviewing designs and identifying potential bottlenecks)

Outside the business

Cloud Providers (for understanding infrastructure metrics and optimisations)
Tool Vendors (for support and advanced features of our performance tooling)

7What you need before you start

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

Proven experience independently designing, executing, and analysing performance tests for complex applications (not just running existing scripts).
Demonstrable ability to perform deep-dive root cause analysis using APM tools, profilers, and log aggregators.
Strong scripting skills in at least one language (e.g., Python, Java, Go) for test automation and data manipulation.
Experience collaborating directly with development teams to implement performance optimisations.
A solid understanding of software development lifecycle and CI/CD pipelines.
The ability to clearly communicate technical findings to both technical and non-technical audiences.

8What to practise next

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

Advanced eBPF for Production Profiling

Traditional profilers often have a noticeable overhead, making them unsuitable for continuous production monitoring. eBPF offers incredibly low-overhead, deep kernel-level visibility into system behaviour, allowing for safer and more precise production diagnostics without impacting live services.

eBPF Program Types · Kernel-User Space Communication · Observability Tools Using eBPF (e.g., Pixie, Falco) · Performance Analysis with BCC/BPFtrace

This week: Read an introductory article or watch a talk on eBPF to grasp the core concepts.
This month: Set up a local Linux environment (e.g., a VM or Docker Desktop with kind/minikube) and experiment with basic BCC tools.
Month 2: Try to write a simple `bpftrace` script to monitor a specific system call or function in a test application.
Month 3: Investigate how eBPF-based tools could augment our existing APM/observability stack for production troubleshooting.

Quick win: Explore `bpftrace` examples online and run them in a safe test environment to see the kind of insights they provide into system calls and kernel events.

Chaos Engineering for Performance Resilience

It's not enough for systems to perform well under normal load; they must also perform predictably when things go wrong. Chaos engineering helps us proactively identify weaknesses in our systems' resilience to failures, which often manifest as performance degradations or outages.

Hypothesis-Driven Experimentation · Blast Radius Containment · Failure Modes & Effects Analysis (FMEA) · Tools for Chaos Engineering (e.g., Gremlin, LitmusChaos)

This week: Read 'Chaos Engineering' by Principles of Chaos.org.
This month: Identify a non-critical service in a staging environment and brainstorm potential failure scenarios (e.g., network latency, CPU spike).
Month 2: Experiment with a simple chaos engineering tool (e.g., `netem` for network latency) in a safe test environment to observe system behaviour.
Month 3: Propose a small-scale chaos experiment to your team to test the resilience of a specific component under performance degradation conditions.

Quick win: Run a simple experiment in a local development environment: introduce artificial network latency to a microservice dependency and observe how your application handles it.

9Staying current once you are in

What people here do to keep up

Actively participate in online performance engineering communities and forums (e.g., LinkedIn groups, Reddit's r/performanceengineering).
Attend industry conferences and webinars focused on performance, observability, and SRE (e.g., QCon, KubeCon, PerfGuild).
Contribute to open-source performance testing tools or related projects.
Pursue advanced online courses or specialisations in areas like distributed systems, cloud architecture, or advanced statistical analysis.
Regularly read and review academic papers or industry blogs on new performance optimisation techniques and research.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, performance engineering is often about sifting through mountains of data, writing repetitive scripts, and translating complex metrics into plain English. What if you could cut out a significant chunk of that grunt work? We're actively integrating AI tools to help our Senior Performance Engineers reclaim their time and focus on the truly challenging, interesting problems. This isn't about replacing you; it's about making you a performance engineering powerhouse.

Imagine having a tireless assistant that can analyse logs, generate test scripts, and even draft incident summaries for you. That's the reality we're building. For a Senior Performance Engineer, this means less time wrestling with data and more time designing innovative test strategies, deep-diving into the hardest problems, and mentoring your team. Here's a glimpse of how AI can transform your day-to-day:

Automated Workload Model Generation

AI analyses production traffic logs from Datadog or similar APM tools to automatically generate realistic Gatling or k6 scripts. These scripts mimic true user journeys, session lengths, and think times, virtually eliminating the manual, tedious process of script creation. You'll move from hours of scripting to minutes of review.

Predictive RCA for Performance Dips

AI continuously monitors APM data, correlating thousands of metrics across different services. It can pinpoint the probable root cause of anomalies within minutes, flagging a specific code deploy or infrastructure change as the likely source of a latency increase. This means you spend less time hunting and more time fixing.

Institutional Knowledge Chatbot

An LLM trained on our internal Confluence, past incident reports, and post-mortems. You can ask it, 'What was the root cause of the Q4 outage on the checkout service?' and get a summarised answer with links to the relevant documentation. No more digging through endless wikis; the answer comes to you.

Test Summary & Impact Translation

AI ingests raw test results (like JMeter CSVs, Grafana dashboards, or WebPageTest waterfalls) and drafts an executive summary. It translates complex technical metrics (e.g., p99 latency, error rate, CPU steal time) into projected business impact, helping you communicate effectively with non-technical stakeholders.

Common questions

The honest bit

You’ve started things before

Most of them were built for a room full of people who aren’t you. A cohort moves on whether or not your week allowed it, and by the third week the thing you’re behind on becomes the reason you stop opening it.

There’s no cohort here, and no timetable to fall behind. Before anything starts, Zavmo asks when you’re sharpest and how long you can realistically sit down for, then builds the sessions around those answers. A bad fortnight changes your pace. It doesn’t put you behind.

And you only pay once you start learning. Searching and planning are free, and you can cancel any time — so the cost of finding out is an afternoon, not a year.

What it costs

Less than one coaching session. Every month.

A single career-coaching hour costs more than a month of this, and it ends when the hour does. Zavmo doesn't. It's £70 a month, about £2.30 a day, for a companion that knows a Senior Performance Engineer, works on the job you actually do, and keeps going at your pace rather than a timetable's.

Searching and planning stay free. You only pay when you start learning.
Your credits are yours. Regulated, and they don't vanish when a subscription ends.
Cancel any time and billing stops. No notice period, no minimum term.

Your path, personalised

You have the map. Walking it is the part we do together.

This route runs to 7 national skill standards. That is a real journey.

Zavmo shapes a learning experience as unique as you are. It fits how you learn, your pace and the work you already do. Every step stays benchmarked to recognised national standards.
