• Coordinate with carriers and locker providers to ensure timely resolution of reported issues, including clear communication, escalation, and follow-up on open tickets
• Drive continuous improvement in testing processes by leveraging automation and integrating best practices
• Provide guidance on bug tracking, test documentation, and defect resolution processes
• Ensure compliance with regulatory requirements and industry standards related to product quality and safety.

• 5+ years of experience in software quality assurance, ideally working on both backend and frontend systems
• A strong track record in delivering high-quality web and backend applications, especially consumer-facing products
• Solid understanding of QA methodologies, test case development, defect tracking, and test planning
• Hands-on experience with automated UI testing tools and frameworks
• Comfortable collaborating on API testing, performance/load testing, and supporting scalable quality pipelines
• Experience with customer service systems (Jira Service Desk, Zendesk, etc)
• Experience with Git, Agile development practices, and CI/CD pipelines (e.g., GitHub Actions)
• Familiarity with monitoring and observability tools (e.g., Datadog) to support test coverage and incident analysis
• Strong analytical, problem-solving, and communication skills, with a pragmatic and autonomous approach to work

Bonus Points

• Familiarity with test tools such as Playwright, Cypress, or Selenium.
• Programming experience in any of the languages: Java, Kotlin, TypeScript, Go, etc.
• Experience working in regulated environments or with compliance standards (e.g., ISO, GDPR, etc.).
• Contributions to QA best practices, tooling, or community resources.
• Hands-on experience with hardware testing, including device integration, firmware validation, and end-to-end system testing

• Dynamic workplace: A digital environment with international projects and space to learn and grow
• Flexible work conditions: Hybrid working mode with a tailored remote policy
