We're working with a global financial technology group undergoing a major transformation to modernise its post-trade infrastructure. The organisation is transitioning from Legacy systems to a cloud-native, Kafka-based architecture designed for resilience, scalability, and performance.
You'll be part of a growing Non-Functional Testing (NFT) team responsible for ensuring that services and platforms meet the highest standards for performance, reliability, and operational readiness. This is a technically rich role, working across multiple domains including performance, failover, disaster recovery, resilience, alerting, and monitoring.
Responsibilities- Define, document, and execute Non-Functional Requirements (NFRs) across distributed microservices and infrastructure components.
- Collaborate with architects, product owners, and engineering squads to translate NFRs into measurable test scenarios.
- Develop and implement NFT strategies covering performance, scalability, failover, DR, resilience, alerting, and monitoring.
- Design and execute load, stress, endurance, and failover tests using industry-standard tools such as JMeter, LoadRunner, or ADS.
- Set up observability dashboards (Grafana, Splunk, Dynatrace, Kibana, or Datadog) to monitor test execution and system performance.
- Analyse results to identify performance bottlenecks, system vulnerabilities, and areas for optimisation.
- Report findings and recommendations clearly to both technical and non-technical stakeholders.
- Contribute to test automation frameworks, CI/CD integration, and continuous improvement of NFT processes.
- Support the onboarding of new services and provide input into architectural reviews from an NFT perspective.
- Experience in Non-Functional or Performance Testing roles within complex or regulated technology environments.
- Proven experience designing and executing tests across multiple NFT domains (performance, DR, failover, resilience, and scalability).
- Strong understanding of distributed architectures, Java microservices, and containerised deployments.
- Proficiency with testing and monitoring tools such as JMeter, LoadRunner, Grafana, Dynatrace, Splunk, or AppDynamics.
- Familiarity with CI/CD and DevOps tooling - Jenkins, Docker, Kubernetes, and related ecosystems.
- Ability to interpret system logs, analyse performance metrics, and provide actionable recommendations.
- Excellent stakeholder management and communication skills, with the ability to influence across technical and business teams.
- Experience working in Agile delivery environments with cross-functional teams.
- Background in financial services or experience supporting Legacy-to-modernisation migrations.
- Understanding of infrastructure observability, cloud platforms, and microservice orchestration.
- Exposure to automation frameworks and Scripting for performance testing.
This is a key role within a global transformation programme - offering the chance to shape how performance, resilience, and reliability are engineered into one of the world's most critical financial technology platforms.
