Quality Engineer

The role

We are looking for a Quality Engineer to join our team in Lithuania. Quality at CUJO AI is not a final checkpoint — it’s embedded into how we build. Our products run on real home networks, protecting real families, which means quality issues have a direct impact on customers. The E2E Quality team works across firmware, cloud backend, and mobile products to ensure that what we ship is solid, safe, and reliable. We believe the best quality engineers are defined less by the number of tests they write and more by their judgment about what matters to test. We’re looking for someone who can think like an engineer, reason about risk before it becomes a defect, and influence how the whole team approaches quality — not just their own slice of it. Build automation that lasts – write Python-based test automation that is clean, maintainable, and actually used by the team. Follow CUJO’s standards and take pride in code that holds up over time. Stay close to the customer – ground your testing in how real customers use the product. Translate real-world usage patterns into meaningful test coverage and surface issues before they reach production. Contribute to quality outcomes – take responsibility beyond test execution. Understand release readiness, communicate risks clearly, and support quality decisions with data. Track and communicate risk – keep stakeholders informed on quality status, open defects, and mitigation plans. Connect what’s happening in testing to what it means for the release. Contribute to quality strategy – participate in shaping test approaches that reflect both technical risk and customer impact. Make sure QA activities are transparent, measurable, and sustainable. Share what you know – document your work, share learnings with the team, and contribute to a company-wide culture of quality.
