• Actively participate in code reviews and QA process improvements, advocating for best practices and continuous quality enhancements.
• Continuously improve testing coverage and efficiency by introducing new tools, frameworks, and AI-assisted testing techniques (e.g., GitHub Copilot, Claude Code).
• Collaborate closely with product managers, architects, developers, and QA engineers to align on quality goals and deliverables.
  
  

• 5+ years of professional, product focused testing experience (manual and automation) for desktop and/or web applications, including API and end-to-end testing expertise.
• Proficient in C# for building, maintaining, and executing automated test suites.
• Strong knowledge of software QA methodologies, tools, and processes.
• Experience mapping test strategies to requirements, creating detailed test plans, preparing test data, and executing tests efficiently.
• Familiarity with AI-assisted tooling (e.g., GitHub Copilot, Claude Code) to improve testing speed and reliability.
• Hands-on experience with test case management tools (e.g., TestRail).
• Solid understanding of relational and/or non-relational databases.
• Comfortable working with agile development practices such as Scrum or Kanban.
• Strong grasp of Git, version control best practices, and CI/CD workflows.
• Familiarity with tools and platforms like Postman, Linear, Notion, and GitHub as well as cloud environments like Microsoft Azure and AWS.
• Excellent collaboration and communication skills, with experience working closely with developers and cross-functional teams.
• A self-starter who takes ownership, enjoys learning and sharing knowledge, and has a practical, down-to-earth approach.
  
  

• Experience testing AI/LLM-based solutions, including model accuracy, correctness, and performance validation.
• Experience with Power Automate, MSTest, Cypress, and Playwright.
• Familiarity with Azure OpenAI Service, AWS Bedrock, or similar AI platforms.
• Experience testing OfficeJS applications or add-ins.
• Background in the LegalTech domain or other highly regulated industries.
• QA certifications (e.g., ISTQB) or other relevant software testing certifications.
  
  

• We offer a highly competitive salary that reflects your skills, experience, and contributions.
  
  

• Join a fast-growing startup where your ideas matter; experiment, innovate, and see your work come to life.
