Role Overview

We are looking for a Senior Performance Tester to deliver hands-on load and performance testing across large-scale digital services and backend applications, with experience of working with cloud-based distributed services.

This is a technical, delivery-focused role operating in structured and governed environments where performance, resilience, and scalability are critical to service success.

Key Responsibilities

Design and execute load, stress, volume, soak, and scalability tests
Analyse performance results, logs, and system metrics to identify bottlenecks
Gather and Validate performance NFRs, volumetrics, and capacity assumptions
Prepare and maintain performance test scripts and execution runbooks
Execute tests in cloud-hosted (AWS) non-production environments
Raise performance defects with clear technical evidence
Support CI/CD integration for performance testing where required
Contribute to test reports, defect triage, and test completion evidence
Work closely with developers, architects, platform, and operations teams

Essential Skills & Experience

Strong experience in performance testing of enterprise systems
Hands-on delivery using tools such as JMeter, Gatling, LoadRunner, k6 (or equivalent)
Solid understanding of:

APIs, HTTP, databases, messaging, caching
Backend and distributed system performance characteristics

Experience analysing logs and monitoring data
Familiarity with Agile and hybrid delivery models
Experience working in regulated or high-assurance environments

Desirable

Experience with APM tools (e.g. Dynatrace, AppDynamics, Elastic Search with Kibana/Grafana across digital services)
Public-sector or large programme delivery experience
Familiarity with GDS

Scope & Accountability

Responsible for hands-on performance test design and execution
Owns quality and accuracy of assigned test artefacts and results
Contributes analysis and recommendations but does not hold final assurance authority
Works under the direction of a Lead Performance Tester or Test Manager
Accountable for timely delivery of agreed performance testing activities
