🏢 Summary: Greenfield Software Developer in Test role focused on architecting and building AI-driven test automation for a large, complex C#/.NET and Angular platform. The position centers on creating Playwright-based frameworks, LLM-powered test generation, and fully integrating intelligent, self-healing testing into CI/CD pipelines. You will define the overall AI-assisted quality strategy and automate deep business logic validation at scale. 🗂️ Requirements: Strong software development experience with production-quality code, Hands-on experience building automation frameworks with Playwright, Proven daily use of AI coding tools (e.g., Claude, Copilot, Cursor), Deep knowledge of test automation architecture and maintainability, Experience integrating automated tests into CI/CD pipelines, Experience working with large, complex or legacy codebases, Ability to design AI-driven test generation and self-healing frameworks, Strong debugging and root cause analysis skills, Ability to work independently and own test strategy end-to-end 📃 Skills: C#, .NET, TypeScript, Angular, Playwright, CI/CD, Claude, GPT, Copilot, Cursor, LLM, AI, SaaS 🏢 Description: Most QA still works the way it did ten years ago. Manual test plans, slow regression suites, automation scripts that break every sprint. We want someone who thinks that’s a waste of good engineering talent… and can prove it. We’re looking for a Software Developer in Test who will build an entirely new approach to quality for a large, complex C# / .NET platform. Not someone who writes test cases. Someone who architects AI-driven testing systems, automates what others do by hand, and sets the standard for how this team ships reliable software. You’ll use tools like Claude, Cursor, and Copilot not as toys but as core infrastructure. You’ll design and build AI-powered test generation, integrate Playwright-based automation into CI/CD pipelines, and create frameworks that make manual regression testing a thing of the past. This is a greenfield role. There’s no existing AI testing setup to inherit, you’re building it from scratch. About the Project: The project is a long-running, business-critical system with a complex domain and significant technical depth. Large enterprise/SaaS, substantial legacy code, high-load architecture. The kind of system where bugs are expensive and quality can’t be an afterthought. Tech stack: C# / .NET (backend), Angular / TypeScript (frontend), Playwright (test automation). Key Responsibilities: Design and build AI-driven test automation frameworks from the ground up using Playwright; Create systems that use LLMs (Claude, GPT, Copilot) to generate, maintain, and optimize test suites automatically; Develop intelligent test generation that understands the codebase, not just surface level UI clicks, but deep business logic coverage; Integrate AI-assisted testing directly into CI/CD pipelines so quality checks happen on every commit; Build self-healing test infrastructure that adapts when the application changes, instead of breaking; Architect the overall test strategy for a complex C# / .NET and Angular / TypeScript platform; Work with developers to shift testing left, catching issues at the code level, not after deployment; Analyze test results with AI to identify patterns, flaky tests, and coverage gaps automatically; Set up monitoring and reporting that gives the team real confidence in every release; Document your frameworks and train the team to work with AI-assisted testing tools. Qualifications: Strong software development background, you write production-quality code, not just test scripts. C# / .NET or TypeScript experience preferred; Hands-on experience with Playwright. You’ve built real automation frameworks with it, not just followed tutorials; Proven track record using AI coding tools (Cursor, Claude, Copilot, or similar) as part of your daily workflow, not just experimentation; Deep understanding of test automation architecture: what to test, how to structure it, how to keep it maintainable at scale; Experience with CI/CD integration, you know how to make test automation a seamless part of the delivery pipeline; Familiarity with large, complex codebases. Legacy code doesn’t scare you, it motivates you; Strong debugging instincts. When something fails, you find the root cause, not just the symptom; You can work independently and take full ownership. This role has no playbook, you’re writing it; Bonus: experience with test generation, mutation testing, or AI-based code analysis. Recruitment Process: Initial interview with our recruitment team; Technical interview with the client; Final decision and offer.
