As part of large-scale application modernization and evolution projects, we are looking for a Senior QA Lead specializing in performance, capacity, and application robustness.
You will act as a performance reference within complex project teams, working closely with development, architecture, infrastructure, and business stakeholders. Your role will be to secure the performance, stability, and scalability of delivered solutions, intervening proactively throughout the entire project lifecycle.
The position is part of a performance engineering approach, where performance is considered a structuring factor of quality, business value, and operational reliability.
- Define and implement performance strategies covering multiple dimensions: technical performance, application usage, capacity, robustness, and resilience
- Intervene early in projects to identify performance risks during design phases (architecture, technology choices, integration patterns)
- Participate in application architecture reviews from a performance, capacity, and scalability perspective
- Design test scenarios representative of real usage, including critical user journeys, batch processing, high-volume operations, and peak periods
- Define acceptable performance criteria (SLA, SLO, thresholds, capacity objectives) in collaboration with business and IT teams, considering operational constraints and market standards
- Prepare, execute, and analyze load, scalability, stress, spike, and robustness tests on pre-production or controlled production environments
- Analyze performance test results and correlate them with observability data (metrics, logs, traces) to identify application or infrastructure bottlenecks
- Work closely with development, infrastructure, and operations teams to identify root causes of performance issues and support remediation plans
- Produce and communicate clear, decision-oriented performance indicators (KPIs) to both technical and non-technical stakeholders
- Contribute to go-live decisions by providing an objective assessment of performance, capacity, and stability risks
- Integrate and promote performance testing within CI/CD pipelines, following a continuous performance and regression-prevention approach
- Act as a technical leader and reference in application performance, contributing to the continuous improvement of QA practices and organizational standards
- Significant experience in software quality assurance, with strong expertise in application performance, capacity, and load testing
- Solid understanding of performance-related technical challenges: resource management, data volume, batch processing, inter-system integrations, latency, and contention
- Ability to think in terms of performance engineering, beyond simple test execution
- Experience with performance testing tools such as JMeter, Gatling, k6, LoadRunner, or equivalent
- Strong knowledge of observability and APM tools (e.g., Dynatrace, Datadog, New Relic, AppDynamics, Grafana, Prometheus, Elastic Stack)
- Good understanding of modern application architectures (microservices, APIs, event-driven architectures, public cloud)
- Hands-on experience with containerized and orchestrated environments (Docker, Kubernetes), including capacity planning and autoscaling concepts
- Ability to integrate performance testing into CI/CD pipelines (GitLab CI, GitHub Actions, Azure DevOps, Jenkins, or equivalent)
- Understanding of database performance challenges (queries, indexing, data volumes) and ability to collaborate with DBA or data teams
- Excellent analytical, synthesis, and communication skills, with a strong advisory and influencing mindset
- Autonomy, rigor, critical thinking, and a strong sense of ownership.
