Software Engineer - Tester

This role focuses on modern, automation-first quality engineering, leveraging AI-assisted testing, autonomous test generation, and intelligent validation to accelerate delivery across multiple products and teams. The engineer will design, build, and evolve automation frameworks while introducing AI-driven capabilities ("vibe coding", generative testing, self-healing tests, etc.) to improve software quality and team productivity., * Lead and evolve the end-to-end test strategy across multiple teams and product lines.

• Architect, develop, and maintain advanced automated test frameworks using C#, Python, or similar languages.
• Integrate AI/ML-based test generation and analysis tools (e.g., GitHub Copilot, Claude, ChatGPT-based test assistants, Mabl, Testim, Functionize).
• Implement autonomous or semi-autonomous testing workflows, including:

• Generative test creation
• AI-assisted code reviews for test coverage
• Intelligent defect triage and prioritisation
• Self-healing test scripts

• Enhance and maintain CI/CD pipelines to support automated quality gates, using tools such as Azure DevOps, GitHub Actions, Jenkins, or GitLab CI.
• Define and maintain high-quality performance, regression, integration, and acceptance test suites.
• Build and manage synthetic data and AI-assisted test data generation environments.
• Collaborate closely with development, DevOps, and product teams to embed quality early in the SDLC.
• Champion continuous improvement in automation practices, tooling, and AI-driven testing.Produce clear, high-quality documentation for automation frameworks, testing processes, and AI-enabled tools.

Do you have experience in xUnit?, Do you have a Master's degree?, Automation & Development

• Strong hands-on C# automation experience and solid software engineering fundamentals.
• Expertise using automation frameworks such as Selenium, Cypress, Playwright, NUnit, xUnit.
• Experience integrating AI testing tools or LLM-driven assistants into test workflows.
• Ability to build robust, reusable test components and frameworks.

AI-Augmented Quality Engineering

• Experience or strong interest in using LLMs/AI for:

• Generating test scripts
• Code validation
• Impact analysis
• Test optimisation

• Familiarity with prompt engineering concepts and AI safety considerations.

CI/CD & DevOps

• Strong experience with Azure DevOps, GitHub Actions, Jenkins, or GitLab CI.
• Proven ability to create automated quality gates and pipeline-integrated testing.
• Good understanding of Git and branching strategies.

Testing Practices

• Strong grounding in unit, integration, regression, and performance testing.
• Experience with API testing tools (Postman, Swagger tooling, REST Assured, etc.).
• Knowledge of containerisation (Docker/Kubernetes) for consistent test environments.

Business Analysis & User-Centric Quality

• Strong ability to engage with customers, users, product owners, and business analysts.
• Skilled in extracting, clarifying, and challenging requirements to ensure shared understanding.
• Capable of translating requirements into clear acceptance criteria and testable conditions.
• Acts as a voice of the end user, ensuring that "meets criteria" is validated against real user needs, not just technical specifications.

Desirable Skills

• Experience with cloud (Azure/AWS/GCP) test environments.
• Knowledge of IaC tooling (Terraform, Bicep, Ansible).
• Experience with observability platforms (Grafana, Kibana, Application Insights).
• Familiarity with ML model testing or data validation frameworks.Understanding of security testing (SAST/DAST) and AI governance.

Education & Seniority

• Degree or equivalent in Computer Science, Software Engineering, or equivalent experience.
• Mid to Senior level depending on automation & AI experience.
