Initial 12-month contract (extendable)
Clearance: BPSS required
We are hiring multiple NFT Leads to help drive a flagship multi-year Quality Assurance transformation programme for a major UK client.
As part of a SAFe Agile delivery, this is a hands-on, technical role — not just coordination. You will own the design and execution of non-functional tests covering performance, scalability, failover, and security validation. You’ll be building automation libraries, executing scenario-based testing, and providing clear data-led insights to readiness gates and go-live decisions.
What you'll do:
Design & execute performance, scalability, failover, and soak tests
Run load and resilience testing to validate system behaviour under stress
Manage NFT artefacts and dashboards aligned to release decision points
Drive automation uplift and reusable test libraries into CI/CD pipelines
Ensure monitoring & environment alignment for NFT accuracy
Integrate security testing: threat modelling, vulnerability, and penetration testing
Support ITHC readiness, operational acceptance (OAT), and recovery test walkthroughs
Collaborate with DevOps, infrastructure, automation, and client teams
Track and document failure patterns and regressions across test stages
What you'll bring:
Strong experience in non-functional testing: performance, failover, and resilience
Ability to build risk-based test scenarios, not just run template scripts
Skilled in tracking and analysing performance regressions
Strong CI/CD mindset: integrate NFT into DevOps pipelines
Ability to work closely with triage teams and provide decisive test data
Hands-on security validation and ITHC preparation experience
Tech environment:
Must-have:
Test & Reporting: qTest, Jira, Xray, Allure, Confluence
