• Partner with the engineering and product team throughout the software development lifecycle to build quality into every feature from the start.
• Design, build and maintain automation frameworks and automated test suites across UI, API and end-to-end testing, integrated into our CI/CD pipelines.

• Collaborate across engineering to improve testability, investigate production issues and establish QA automation best practices.
• Use LLMs and AI coding assistants (such as Claude, Cursor, GitHub Copilot or similar) as a core part of your engineering workflow to accelerate test design, automation and debugging.
• Champion AI adoption across Quality Engineering by introducing AI-native testing approaches, establishing best practices and using production insights to continuously improve quality.
• Validate AI-generated code and AI-powered product capabilities, ensuring outputs are reliable, secure and suitable for production use.

Your impact will be visible, measurable, and global.

• Strong understanding of software testing principles, risk-based testing and automation framework design.
• Experience building automated UI and API test suites and integrating them into CI/CD pipelines.

• Experience with modern automation tools such as Playwright, Cypress, Postman, Jest or similar technologies.
• Hands‑on experience using LLM platforms and AI coding assistants (such as Claude, ChatGPT, Gemini, Cursor or GitHub Copilot) as part of your day‑to‑day engineering workflow, with the judgement to know when AI-generated outputs require human review.
• Strong communication skills with the ability to collaborate across cross‑functional engineering teams.
• A proactive, curious mindset with a passion for continuously improving quality engineering practices.

• Experience testing AI‑powered products, LLM‑based applications, RAG systems or agentic workflows.
• Experience with AI‑native testing platforms or autonomous testing solutions (such as Mabl, Testsigma, Katalon TrueTest, KaneAI, Applitools or similar).
• Experience with production observability and shift‑right testing practices.
• Prompt engineering experience for software development or test generation.

At Gravitee, our growth is powered by people who bring passion to what they build, act with professionalism in how they work, and hold nothing back in their commitment to doing things well.

You’ll do well here if you:

• Care deeply about quality, clarity, and impact
• Are curious, adaptable, and excited by emerging technologies like AI
• Take ownership and follow through
• Value collaboration, openness, and continuous improvement

Bonus points if you’ve worked with APIs, cloud‑native platforms, AI‑enabled systems, or open source, but curiosity matters most.
