Senior Manual QA Engineer

Ciklum is looking for a Senior Manual QA Engineer to join our team full-time in Ukraine.

We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.

About the role:

As a Senior Manual QA Engineer, become a part of a cross-functional development team engineering experiences of tomorrow. We are looking for a Manual QA Engineer / Test Analyst to work closely with the AQA engineer and development team on a complex, data-heavy web application for strategic roadmapping, portfolio planning and performance metrics. The focus is on ensuring data accuracy, business logic, API behaviour and visualisations, not only testing the UI.

Responsibilities:

• Design and execute functional, integration, regression and exploratory tests
• Strong focus on API testing, using tools such as Postman or similar
• Validate data processing, data consistency and data integrity across different parts of the application
• Test complex business rules, calculations, relationships and dependencies
• Validate roadmaps, timelines, charts, dashboards and other data visualisations
• Verify that front-end visualisations correctly represent the underlying data
• Work closely with AQA to identify what should be automated and what requires manual validation
• Analyse defects, provide clear reproduction steps and work closely with developers to resolve issues
• Support test planning and ensure appropriate coverage for new functionality
• Perform end-to-end and regression testing across the application

Requirements:

• Strong experience testing complex B2B / enterprise web applications
• Good understanding of APIs, data structures and databases
• Comfortable working with large and complex datasets
• Strong analytical and investigative skills
• Able to challenge requirements and identify edge cases and inconsistencies
• Comfortable working in a lean, fast-moving environment with evolving requirements
• Good collaboration with Product, Design, Development and AQA

Desirable:

• Don't just check whether it works - check whether the right thing is happening, with the right data, in the right way
• The ideal person is analytical, curious and detail-oriented, with a strong interest in understanding what happens behind the UI, not just whether the screen looks correct

What’s in it for you?

• Strong community: Work alongside top professionals in a friendly, open-door environment
• Growth focus: Take on large-scale projects with a global impact and expand your expertise
• Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications
• Endless opportunities: Explore diverse domains through internal mobility, finding the best fit to gain hands-on experience with cutting-edge technologies
• Flexibility: Enjoy radical flexibility – work remotely or from an office, your choice
• Care: We’ve got you covered with company-paid medical insurance, mental health support, and financial & legal consultations
