London, United Kingdom WeDoTech Full time

Job Title: Senior QA Engineer / SDET
Salary: Up to £80,000 base + bonus and enhanced pension
Location: South London Hybrid working with two days per week onsite
Work Type: Permanent
 
Role:
This is a Senior level QA Engineer / SDET role within a high impact product team working on an industry leading SaaS platform that actively leverages AI and ML in production. Quality, risk, and reliability are treated as core engineering disciplines rather than support functions.
 
You will be part of a large and established QA community of over 60 highly skilled QA professionals. Managers and senior leaders within the group are recognised speakers in the QA community and are active thought leaders within the AI testing space, offering strong mentorship, exposure, and long term career development.
 
The role operates as an embedded position within a cross functional Scrum team, with a clear split in impact: approximately 50% of your time will focus on AI agents and AI driven capabilities, and 50% on the organisation’s industry leading SaaS offering, helping push the boundaries of how AI can be applied within an evolving industry.
 
Responsibilities:
• Take ownership of quality and test risk, shaping release confidence and engineering decisions across the platform
• Define and evolve test strategies across unit, integration, contract, and UI layers, aligned to the test pyramid
• Deliver hands on automation and quality engineering across two key domains: AI agents and a complex SaaS platform
• Contribute directly to AI testing initiatives, helping validate, monitor, and improve AI driven capabilities in production
• Build, maintain, and optimise automated test suites within CI/CD pipelines
• Work with Cypress for UI automation, with scope to influence future Playwright adoption
• Design and maintain contract testing using PACT within a microservices architecture
• Collaborate closely with engineers, product, and platform teams to embed quality throughout the development lifecycle
• Support reliability, security, and performance initiatives, including resilience and fault tolerance testing
• Promote strong quality engineering standards and best practice across teams and the wider QA community
 
Required Skills:
• Strong understanding of architectural differences between monolithic and microservices based systems
• Programming experience in C# .NET or Python
• Solid database knowledge and hands on experience working with data driven systems
• Experience testing and validating API integrations
• Exposure to security and load testing practices
• Strong CI/CD pipeline experience, ideally using Azure DevOps
• Performance testing experience using tools such as K6 or Jmeter
 
Why?
This role has been created due to continued growth and increasing investment in AI driven capabilities across the platform. The team is pushing the boundaries of what is possible with AI in a regulated, production grade SaaS environment, and quality engineering is central to that ambition.
 
Recruitment process:
Stage 1: CV walkthrough and culture fit conversation
Stage 2: Take home tech test
Stage 3: Onsite face to face interview
