Performance Test Engineer in Sheffield

Performance & Non-Functional Testing Lead

Our Technology teams work closely with our global businesses to design and build digital services that allow millions of our customers around the world to bank quickly, simply and securely.

We run and manage our technology infrastructure, cloud and core banking systems that power the world’s leading international bank, with one of the largest technology estates in the industry.

At HSBC we’re redefining Identity and Access Management (IAM) on a global scale and launching a transformational programme to bridge modern IDAM technology and solutions with big bank scale and complexity.

The IAM Transformation program is forecast to be 5 years plus with significant change to be designed, planned and implemented globally.

The transformation encompasses all aspects of IAM from Authentication through to elevated access and will cover human and non-human identities.

Role Summary

We are looking for a highly skilled

Performance & Non-Functional Testing Lead with strong expertise in validating the scalability, resilience, and operational readiness of complex, cloud-based services (e. g.,

Google Cloud Platform ).

This role focuses on defining and delivering a programme-wide

Performance & Non-Functional Testing strategy, translating non-functional requirements into measurable outcomes, and executing robust testing across load, stress, volume, failover, high availability, and disaster recovery scenarios.

Using a quality-first, engineering-led approach, you’ll collaborate closely with Scrum teams, Architects, Dev Ops, Product, and support teams to embed

Performance & Non-Functional Testing into delivery pipelines, provide clear risk-based reporting, and drive performance insights and remediation that enable safe, scalable releases.

Key Responsibilities

• Own the overall programme’s Performance & Non-Functional Testing capability end-to-end.
• Own and maintain the Performance & Non-Functional Testing strategy and roadmap for the programme.
• Define and execute Performance & Non-Functional Testing strategies across services, mentor testers, and collaborate with Scrum teams, Architects, Dev Ops, and support teams to ensure systems are scalable, reliable, and performant under load.
• Bring deep test management expertise, including Performance & Non-Functional Testing processes and standards, with experience defining long-term strategy (tooling, environments, and resourcing) and gathering non-functional requirements for complex, global transformation programmes.
• Propose tooling selection and approach and make recommendations for proving functionality through proof of concept (Po C) where required.
• Deliver Performance & Non-Functional Testing for cloud-based applications (e. g., GCP).
• Plan Performance & Non-Functional Testing coverage and test frequency across the programme.
• Oversee delivery and execution of Performance & Non-Functional Testing, including progress and completion reporting, metrics/dashboards, and end-to-end defect management.
• Monitor, analyse, and report key non-functional KPIs during the test process.
• Analyse test execution using profilers, logs, and system statistics; identify bottlenecks and recommend remediation actions.
• Collaborate cross-functionally with product managers, designers, and engineers to define requirements, devise solution strategies, and ensure seamless integration and alignment with business objectives.
• Maintain a strong team-player mindset and contribute positively to delivery outcomes.
• Produce high-quality documentation, visualisations, and presentations that provide clear insight into landscape quality and readiness.
• Ensure audit and log retention testing is planned and executed.
• Prepare and present test reports and analysis to stakeholders, providing clear insight into quality, risk, and release readiness.
• Ensure integration of Performance & Non-Functional Testing tools and results into CI/CD pipelines and reporting frameworks.

Required Skills

• Proven experience delivering high-volume Performance & Non-Functional Testing in complex global environments, including load, stress, volume, disaster recovery, high availability, resilience, and failover testing.
• Experience selecting and recommending test tools based on assessment of the environment/landscape.
• Experience defining a comprehensive Performance & Non-Functional Testing strategy covering approach, environments, scope, risks, and resourcing.
• Strong understanding of cloud (e. g., GCP) Performance & Non-Functional Testing approaches and methodologies.
• Experience delivering within both Agile and Waterfall methodologies.
• Ability to review and provide feedback on complex architecture, solution, and integration documentation.
• Clear, open, and timely communication and reporting skills, including accurate status, risks, and issues.
• Ability to recognise risks and issues and raise/escalate appropriately and promptly.
• Ability to lead other Performance & Non-Functional Testing engineers when required.
• Expert knowledge of JMeter, Gatling, Load Runner, Neo Load (or similar) for load, stress, and volume testing, including licensing considerations, configuration, dashboards, and reporting.
• Expert-level knowledge of Performance & Non-Functional Testing for containerised, serverless, and cloud-native applications, leveraging security, monitoring, alerting, and Infrastructure-as-Code (Ia C) tools.
• GDBMS performance analysis: database performance tuning, query optimisation, connection pooling, and use of database monitoring tools.
• Experience testing graph database management systems (GDBMS).
• Graph platform engineering experience, including Neo4j basics, backups, recovery and disaster recovery, GDS/APOC, and observability.
• Message queue performance experience: testing and analysing throughput, ingestion, integration layer velocity, consumer lag, and event-driven architecture performance.
• Familiarity with Service Now, Active Directory, and AWS/Azure integrations.
• Experience testing functions and decision points “as code” (e. g., policy-as-code).
• Exposure to Git Ops repositories; hands-on experience is highly desirable.
• Hands-on experience with API testing, API gateway testing, batch/ETL testing, test data generation, and mocking.
• Good understanding of security vulnerabilities and non-functional considerations including disaster recovery, failover, operational acceptance testing, volume, and compliance testing.
• Proven team leadership and management capability, including mentoring and developing engineers.

Desired Skills

• Experience testing Identity & Access Management applications/infrastructure or other complex end-to-end infrastructure platforms.
• Experience running Po Cs for new and emerging tooling.
• Experience with APM and monitoring tools (e. g., App Dynamics, Datadog, GCP monitoring suite, or equivalent).
• Ability to integrate Performance & Non-Functional Testing into Git Lab CI/CD pipelines and implement shift-left practices.
• Experience with Pub/Sub and MQ technologies.
• Experience with GCP cloud testing approaches and methodology.
• Experience with Saa S testing approaches.
• Understanding of Docker/Kubernetes performance implications, resource limits, and orchestration impact on application performance.
• Ability to establish Performance & Non-Functional Testing standards, best practices, and governance frameworks across an organisation.
