## About the Role

* Proven Hands-On Experience : Substantial overall commercial experience in software testing, including strong hands-on experience in non-functional/performance testing and test automation.
 * Technical Ownership : Demonstrated experience leading testing efforts for projects or features, defining test plans, and communicating risks clearly to technical and non-technical stakeholders.
 * Performance Testing : Strong practical skills in Apache JMeter, including custom scripting, correlation, parameterisation, and distributed load testing.
 * AWS Cloud Ecosystem : Hands-on working knowledge of core AWS services (such as EC2, ECS/EKS, Lambda, S3, RDS, and API Gateway) and how to monitor them under load.
 * Monitoring & Observability : Practical experience configuring AWS CloudWatch Canaries and building insightful visual dashboards in Grafana (using Prometheus, InfluxDB, or CloudWatch data sources).
 * Test Automation : Proficiency in writing maintainable automated UI or API tests using modern frameworks (e.g., Playwright, Cypress, Selenium, RestAssured, or PyTest) in languages like Python, Java, or TypeScript/JavaScript.
 * CI/CD Integration : Experience embedding automated and performance test suites into CI/CD workflows (e.g., GitHub Actions, Jenkins, GitLab CI, or AWS CodePipeline).

Desirable Skills:

 * Experience with infrastructure-as-code (IaC) tools like Terraform or AWS CloudFormation to spin up test environments and load generators.
 * Familiarity with containerisation and orchestration ( Docker , Kubernetes ).
 * Exposure to other performance or APM tools (e.g., k6, Gatling, Datadog, New Relic, or Dynatrace).
 * Experience testing microservices and event-driven architectures (e.g., SQS, SNS, Kafka).

## Description

We are looking for a capable Senior Test Engineer with approximately 10 years of overall software testing experience, including 2-4 years of hands-on experience in non-functional testing and test automation, and the confidence to take ownership of these areas to ensure our cloud-native applications are fast, reliable, and scalable. In this role, you will design automated test suites, execute performance and load tests, and build synthetic monitoring solutions within an AWS environment.

You will work closely with developers and DevOps engineers to catch bottlenecks early and maintain high system availability.

While this is a hands-on technical role rather than a formal line-management position, you will act as the go-to subject matter expert for performance and automation, helping shape our testing strategy and supporting junior team members., * Manage the Non-Functional Test Phase : Able to run and manage the non-functional test phase end to end, including planning, coordinating test execution, monitoring progress, managing risks and defects, and reporting outcomes and test closure.

 * Lead Performance & Non-Functional Testing : Take end-to-end ownership of designing, scripting, and executing load, stress, endurance, and spike tests using Apache JMeter to uncover bottlenecks and validate scalability.
 * Drive Test Automation : Build, maintain, and enhance automated functional and API test frameworks, ensuring smooth integration into our CI/CD pipelines.
 * Own Synthetic Monitoring : Design, deploy, and manage automated synthetic checks using Amazon CloudWatch Synthetics (Canaries) to continuously validate critical user journeys and API health.
 * Observability & Metrics : Build and maintain clear, real-time dashboards in Grafana and AWS CloudWatch to track test execution, system telemetry, latency, and resource utilisation.
 * Technical Leadership & Collaboration : Act as the quality champion within Agile ceremonies, collaborating with developers and DevOps engineers to define non-functional requirements (NFRs), conduct root cause analysis, and mentor junior testers.
