Manual QA Engineer

3D Frames is looking for a Manual QA Engineer to help us maintain a high quality bar for our web-based 3D configurators.

We develop interactive 3D solutions for international B2B clients in the construction industry, including garden houses, modular containers, rooftop extensions, and other configurable structures.

Our configurators combine complex business logic, interactive 3D scenes, Admin UI, APIs, and document generation. We are looking for someone who enjoys digging into details, finding non-obvious UI/UX issues, testing complex configuration logic, and making sure the final product simply works.

Responsibilities
 

• Test web-based 3D configurators and Admin UI;
• Perform functional, regression, exploratory, and cross-browser testing;
• Test complex configuration logic, dependencies, restrictions, and compatibility rules;
• Verify interaction between UI and 3D scenes;
• Test APIs and integrations using Postman;
• Test PDF generation and configuration output;
• Identify visual, UI/UX, functional, and logic-related issues;
• Create and maintain test cases and checklists;
• Prepare clear and structured bug reports;
• Validate fixes and participate in regression testing before releases;

• Work closely with developers, PMs, and the 3D team to improve product quality.

  
  Requirements
   

• 2+ years of commercial experience in manual testing of web applications;
• Experience creating test cases, checklists, and bug reports;
• Confident knowledge of Chrome DevTools;
• Experience working with Postman and testing REST APIs;
• Basic understanding of HTML / CSS / JavaScript;
• Strong attention to detail, especially when testing UI and visual elements;
• Understanding of web application testing principles;
• Experience with cross-browser and responsive testing;
• Ability to independently investigate issues and clearly describe reproduction steps;
• English — B1+ for documentation and communication.
  
  Will Be a Plus
   
• Experience testing 3D or interactive web applications;
• Understanding of WebGL / Three.js;
• Experience with Figma, Swagger, and Jira;
• Understanding of parameter-based or rule-based configurators;
• Experience testing applications with a large number of states, dependencies, and combinations;

• Basic understanding of 3D concepts such as models, materials, textures, cameras, and scenes.

  
  What You Will Test
   

• 3D configurators with a large number of options, states, and dependencies;
• Configuration rules and restrictions to ensure users cannot create technically impossible combinations;
• UI and interaction with 3D scenes;
• Admin UI;
• APIs and integrations;
• PDF generation;
• Visual consistency and UI/UX;
• Cross-browser compatibility and responsive behavior.

   What We Offer
 

• Stable long-term projects with international B2B clients;
• Fully remote / hybrid work format;
• Full-time cooperation;
• Comfortable working schedule;
• 15 working days of paid annual leave;
• 5 paid sick leave days;
• Paid public holidays;
• Clear tasks, priorities, and communication processes;
• Direct impact on product quality — your findings turn into real product improvements;
• Close collaboration with developers, PMs, 3D specialists, and other QA engineers;
• Opportunity to work with complex 3D web products rather than standard websites;
• Competitive compensation based on your skills and experience.

   Team
 

You will work as part of a cross-functional product team together with:

• Manual QA Engineers;
• Frontend / Three.js Developers;
• Full Stack Developers;
• 3D Artists / Modelers;
• Project Managers.
