- About Scale Factory
We are an AI enablement consultancy.
Delivering quality-led AI-first foundations, embedding capability and excellence into the foundational fabric of the companies we work with.
We give leaders the confidence to move faster, take smarter risks and pursue transformation.
Formerly Ten10, we have deep roots in Quality which means we don’t just build for the future, we ensure it actually works.
We combine this engineering discipline with cutting-edge AI expertise to deliver robust, scalable foundations that turn ambitious transformation into reliable reality.
- Role Responsibilities
- Deliver performance testing solutions to a range of clients, ensuring systems are scalable, reliable, and performant.
- Design, implement, and execute performance test strategies, including load, stress, scalability, and endurance testing.
- Work closely with technical teams and stakeholders, translating business requirements into testable solutions.
- Contribute to functional test automation (e. g., using Selenium, Cypress, Playwright) and ensure alignment between functional and non-functional testing efforts.
- Adopt a \"shift-left\" approach by designing and implementing performance tests at the API, component, and integration levels, not just at the UI/E2E level.
- Engage directly with clients, providing expert advice on performance test best practices.
- Collaborate with development, Dev Ops, and infrastructure teams to identify performance bottlenecks and optimise system performance.
- Utilise performance testing tools such as JMeter, K6, Load Runner, Neo Load, or Gatling.
- Provide insights and recommendations based on test results to drive continuous improvements.
- What We’re Looking For
- Active Security Clearance
- SDET with experience as a Performance Tester, ideally in a consultancy or client-facing environment.
- Proficiency in at least one object-oriented programming language (e. g., Java, Python, C#, or Java Script/Type Script) for writing clean, maintainable test code and frameworks.
- Strong knowledge of performance testing methodologies, tools, and scripting. But equally happy with functional test automation
- Ability to engage with customers, technical teams, and stakeholders to deliver meaningful outcomes.
- Experience in cloud-based and distributed system performance testing.
- A true \"engineer in test\" mindset: able to build custom tools, write high-quality test code, and participate in technical design and code reviews.
- Knowledge of monitoring and diagnostics tools such as App Dynamics, Dynatrace, Datadog or New Relic.
- Strong analytical and problem-solving skills, with a keen eye for detail.
- Demonstrable experience in building E2E functional automation frameworks in addition to a primary focus on performance testing.
