We are a subsidiary of Kyivstar, one of Ukraine’s largest telecom operators.

Our mission is to change lives in Ukraine and around the world by creating technological solutions and products that unleash the potential of businesses and meet users’ needs.

Over 600+ KS.Tech specialists work daily in various areas: mobile and web solutions, as well as design, development, support, and technical maintenance of high-performance systems and services.

We believe in innovations that truly bring quality changes and constantly challenge conventional approaches and solutions.

Each of us is an adherent of entrepreneurial culture, which allows us never to stop, to evolve, and to create something new.

• API and integration testing across microservices
• Performance and load testing
• Test automation and support of existing test builds
• Regression testing
• Testing reporting and documentation

Qualifications and experience needed:

• 4+ years of relevant working experience as a QA Engineer with a backend focus
• Strong backend testing experience: verifying end-to-end data flow between services, databases and message brokers, not only endpoint responses
• Great knowledge of automation tools and Java/TypeScript, with integration into CI pipelines
• Performance testing experience: load profiles, test execution, interpreting latency, throughput and error rate
• Excellent requirements analysis skills — identifying gaps and ambiguities before development starts
• Experience of composing test strategies and test plans
• Test design techniques knowledge
• Confident knowledge of testing methodologies
• SQL knowledge: complex queries with joins and aggregations, data integrity checks
• Linux/UNIX command line: log analysis, basic bash
• Practical skills with Git: branching, merging, code review
• Experience with MOCK-SERVER or a similar tool for isolating dependencies
• Knowledge of TCP, HTTP
• Understanding of client-server and microservices architectures: inter-service communication, failure points, idempotency
• Good knowledge of Postman, IntelliJ IDEA, Atlassian stack (Jira, Confluence, Zephyr), GitLab, Jenkins, Kibana, Grafana
• Higher technical education or equivalent relevant experience
• Ability to work in a fast-paced Agile environment in close collaboration with the development team
• Excellent analytical skills, critical mindset
• Strong communication and troubleshooting skills
• English is spoken and written on the intermediate level or higher

Nice to have:

• Telecom domain experience: billing, charging, provisioning
• Kafka or RabbitMQ
• Docker, Kubernetes
• High-load systems experience

What we offer

• Office or remote it’s up to you.
• You can work from anywhere, and we will arrange your workplace.
• Remote onboarding.
• Performance bonuses for everyone (annual or quarterly depends on the role).
• We train employees: the opportunity to learn through the company’s own library, internal resources and programs from partners.
• Health and life insurance.
• Wellbeing program and corporate psychologist
