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.

Production Incident Reduction (Performance-related P1/P2)
The number of critical or major production incidents directly caused by performance issues within your area of ownership.
Target · Contribute to a 25% reduction year-on-year for your assigned services/programmes.

If your team's services had 12 P1/P2 performance incidents last year, we'd expect to see no more than 9 this year, directly attributable to your interventions and architectural guidance.

Mentorship Success & Team Growth
The readiness of your direct reports or mentees for promotion, reflecting your ability to develop talent.
Target · At least one mentored L2 engineer is ready for promotion to Senior (L3) within a 2-year period, with demonstrable skill growth.

One of your direct reports, who started as an L2, consistently takes on L3-level tasks and shows strong independent problem-solving, leading to a successful promotion within 20 months.

Performance Automation Efficiency
The reduction in manual effort required for performance test setup, execution, and reporting through automation.
Target · Reduce manual effort by 40% across your team's processes within 12 months.

You implement a new CI/CD integration that automatically triggers load tests and generates summary reports, cutting down a 3-day manual process to less than half a day of oversight.

Capacity Planning Accuracy
How accurately your forecasts predict future infrastructure needs based on business growth and performance characteristics.
Target · Achieve a forecast deviation of no more than ±10% for key infrastructure components (e.g., database CPU, message queue throughput) over a 6-month horizon.

You predict a 20% increase in database CPU usage for Q3 due to a new feature, and actual usage comes in at 21.5%, showing excellent forecasting.

Architectural Influence & Proactive Bottleneck Identification
Your ability to spot potential performance issues in design phases, before code is even written, and influence architectural decisions.
  • You're regularly invited to architecture review boards for new services. Development leads actively seek your input on system designs. You've documented several instances where your early input prevented a major performance problem down the line. You're seen as the 'performance conscience' for new initiatives.
Technical Leadership & Cross-Team Collaboration
How effectively you lead performance initiatives across different engineering teams and get everyone on the same page about performance goals.
  • You successfully champion and implement a new performance budgeting standard across three development teams. You're the one who pulls together disparate teams to debug a complex, multi-service performance issue. Other team leads consistently praise your ability to explain complex technical issues clearly and drive consensus.
Knowledge Sharing & Community Building
Your contribution to elevating the overall performance engineering knowledge and practices within the wider organisation.
  • You regularly run internal workshops on advanced profiling techniques or new load testing tools. You've created reusable frameworks or templates that other engineers readily adopt. You're an active contributor to internal performance forums, answering questions and sharing insights.
Mentorship Effectiveness
The demonstrable growth and increased autonomy of the engineers you mentor or directly manage.
  • Your direct reports consistently give positive feedback on your guidance and support. You see your mentees tackling more complex problems independently and contributing more strategically. They're asking better questions and showing improved diagnostic skills.

7Would you like it

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

What people enjoy
Solving the Unsolvable

You get a real kick out of being presented with a 'mystery' performance issue that no one else can figure out. The more complex, the better. You enjoy the deep-dive, the detective work, and the 'aha!' moment when you finally crack it.

Spending days correlating obscure log messages with CPU steal time metrics to uncover a subtle kernel bug that was causing intermittent database timeouts, saving the company from a major incident.

Building for Scale and Efficiency

You're motivated by seeing your architectural recommendations lead to systems that can handle 10x the traffic without breaking a sweat, or by optimising a critical service to run on half the infrastructure, saving real money.

Designing a new caching strategy that reduces database load by 80% during peak hours, directly translating to lower cloud costs and significantly improved user experience.

Mentoring and Elevating Others

You enjoy sharing your deep knowledge, seeing your team members grow, and helping them develop their own performance engineering skills. You find satisfaction in building a stronger, more capable team.

Guiding a junior engineer through their first complex root cause analysis, helping them understand profiling tools and diagnostic techniques, and seeing them successfully identify the issue independently.

What frustrates people
  • The 'It works on my machine' defence from developers.
  • Being forced to sign off on a release after testing on a 'quarter-scale' staging environment, knowing it's not representative of production.
  • The last-minute 'performance blessing' request before a major launch.
  • The Observer Effect: when attaching a profiler changes the system's behaviour, sending you on a wild goose chase.
  • Performance being treated as a 'feature for next quarter' until an actual outage occurs.
  • Requests to 'just run a quick test' that completely ignore the days of effort required for a valid setup.
What this role does not give you
  • A predictable, routine work schedule – expect urgent issues to pop up.
  • A role where you only build new things; a lot of it is about fixing, optimising, and improving existing systems.
  • A quiet, isolated role; you'll be talking to a lot of different people across engineering.
  • A role where every single recommendation you make will be immediately actioned; you'll need to influence and persuade.

8Who you work with

This role directly shapes the performance and scalability of our core products and platforms. Your decisions influence infrastructure spend, customer retention, and our ability to launch new features without breaking existing ones. You'll be setting technical standards and driving the adoption of performance-first engineering practices across multiple development teams, effectively preventing future outages and improving developer productivity.

  • Industry Peers (for best practice sharing)

9What you need before you start

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

  • Proven track record of leading complex performance engineering initiatives for at least 3-5 years, demonstrating significant impact.
  • Demonstrable experience mentoring junior engineers and contributing to their technical growth.
  • Strong understanding of at least one major cloud platform (AWS, Azure, GCP) and its performance characteristics.
  • Hands-on experience with at least two different load testing tools and two different APM solutions at an advanced level.
  • A portfolio or examples of complex performance problems you've diagnosed and solved, detailing your approach and impact (e.g., blog posts, conference talks, internal presentations).
  • Experience presenting technical findings and recommendations to senior leadership and non-technical audiences.

10What to practise next

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

Advanced Distributed Tracing & Service Mesh Performance

Microservices architectures are becoming more prevalent, and understanding performance across hundreds of services is impossible without sophisticated distributed tracing. Service meshes (e.g., Istio, Linkerd) introduce new performance considerations and optimisation opportunities.

OpenTelemetry & W3C Trace Context · Service Mesh Data Plane Performance · Tracing for Asynchronous & Event-Driven Systems · Root Cause Analysis with Trace Visualisations

  • This week: Dive into OpenTelemetry documentation and understand its architecture.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of performance engineering involves repetitive tasks, sifting through mountains of data, and translating complex technical jargon into understandable insights. What if you could offload a significant chunk of that to AI, freeing you up for the truly challenging, strategic work?

Our AI productivity tools aren't here to replace you; they're here to make you a superhero. Imagine automatically generating realistic load test scripts, predicting performance issues before they happen, or getting instant answers from our vast internal knowledge base. That's the power we're putting in your hands, letting you focus on architecting for scale and solving the hardest problems.

Automated Workload Model Generation

AI analyses production traffic logs from Datadog, Splunk, or Prometheus to automatically generate incredibly realistic Gatling or k6 scripts. It mimics true user journeys, session lengths, and think times, eliminating hours of tedious manual script creation and ensuring your tests are always relevant. No more guessing what 'typical' user behaviour looks like.

Predictive RCA for Performance Dips

Our AI continuously monitors APM data (Dynatrace, Datadog, New Relic), correlating thousands of metrics across services to pinpoint the probable root cause of anomalies. It'll flag a specific code deploy, a database change, or even a third-party API slowdown as the likely source of a latency increase within minutes, often before humans even notice.

Institutional Knowledge Chatbot

Imagine an LLM trained on all our internal Confluence pages, past incident reports, post-mortems, and architectural diagrams. Ask it: 'What was the root cause of the Q4 outage on the checkout service?' or 'How do I configure eBPF for JVM applications?' and get a summarised, accurate answer with links to the original documents, saving you hours of searching.

Test Summary & Impact Translation

AI ingests raw test results (JMeter CSVs, Grafana dashboards, APM snapshots) and drafts a comprehensive executive summary. It translates complex technical metrics (p99 latency, error rate, GC pressure) into projected business impact ('potential revenue loss of £X/hour', 'impact on customer churn'), making your findings immediately actionable for leadership.
