We’re looking for a Performance & Non-Functional Testing Lead to shape and lead the testing strategy for large‑scale, cloud‑based platforms. This is a high‑impact role where you’ll define how performance, resilience, failover, disaster recovery, and operational readiness are tested across a complex enterprise environment.

- Translate non‑functional requirements into measurable test outcomes and KPIs
- Collaborate with engineering, architecture, DevOps, product, and support teams to embed testing into delivery pipelines
- Analyse bottlenecks using logs, profilers, monitoring tools, and system metrics
- Deliver clear risk‑based reporting, dashboards, defect analysis, and release readiness updates
- Recommend tooling, environments, and resourcing strategies, including proof of concepts for new tools
- Ensure testing is integrated into CI/CD pipelines
Required Skills
- Proven experience leading Performance & Non‑Functional Testing in large, complex enterprise environments
- Strong hands‑on experience in load, stress, volume, failover, disaster recovery, high availability, and resilience testing
- Expertise with tools such as JMeter, Gatling, LoadRunner, NeoLoad, or similar
- Experience testing cloud‑native, containerised, and serverless applications, ideally on GCP
- Strong coding/scripting skills in Python, Java, Scala, Cypher, or similar
- Experience with database performance analysis, tuning, connection pooling, and monitoring
- Exposure to graph databases such as Neo4j
- Understanding of message queues, throughput, ingestion, and event‑driven systems
- Hands‑on experience with API testing, batch/ETL testing, test data generation, and mocking
- Strong stakeholder communication and team leadership capability
Nice to Have
- Experience with IAM / Identity & Access Management
- Exposure to GitLab CI/CD, GitOps, DevSecOps, and policy‑as‑code
