QA Developer (.NET) – AEC Engineering Software

As a QA Developer, you join our engineering software team and contribute directly to the quality and reliability of advanced desktop and web applications used in the Architecture, Engineering & Construction (AEC) industry.

You combine solid .NET development skills with a strong quality engineering mindset. Your work ensures the correctness of software used by civil engineers, structural engineers, architects, and tendering professionals across complex, calculation-heavy products.

You operate in an international Agile environment based in Budapest, working closely with developers and domain specialists.

About The Team & Products

You join a cross-functional engineering team building software used to design, analyze, and manage construction and infrastructure projects across Europe.

Our applications embed complex engineering logic: calculation engines, data processing workflows, and technical exports where precision and reliability are critical.

Quality is not only about testing features — it is about validating engineering correctness.

What you will do

• Design, develop, and maintain automated test frameworks for desktop and web applications (.NET / C#)
• Write and execute test plans, test cases, and regression suites targeting complex domain-specific functionalities
• Validate calculation engines, engineering workflows, and technical outputs (civil, structural, architectural, tendering)
• Develop automated tests in C# or scripting languages and ensure their robustness and maintainability
• Identify, document, and track defects, and work closely with developers to ensure fast and reliable resolution
• Integrate automated tests into CI/CD pipelines (Azure DevOps or GitLab) and define quality gates
• Participate in code reviews with a focus on testability, reliability, and engineering quality
• Collaborate with domain experts (engineers, architects) to understand requirements, constraints, and edge cases
• Contribute to documentation, test methodology, and knowledge sharing within the team

• Solid experience in software testing (manual and automated) in a .NET environment (C# / C++)
• Strong ability to design and write maintainable, robust test automation code
• Experience with desktop application testing (WPF or similar)
• Familiar with Git and CI/CD pipelines (Azure DevOps or equivalent)
• Comfortable in complex technical environments with strong business logic
• Basic understanding of at least one AEC domain (civil, structural, architectural, or cost estimation)
• Analytical and structured mindset, with strong attention to detail
• Curious and eager to understand engineering problems beyond software

• Knowledge of civil engineering or structural analysis concepts
• Experience with calculation engines or domain-specific technical libraries
• Familiarity with BIM, GIS, or CAD formats (IFC, DWG, GeoJSON…)
• Experience with performance, integration, or system testing in engineering contexts
• Exposure to DevOps practices in engineering software environments
