About the role

We seek a proactive and detail-oriented Senior QA Engineer to join our team. You will be part of a team, collaborating closely with Engineers, Designers, and Product Managers to ensure high-quality outcomes. You will fully own the QA process, drive quality standards and ensure efficient testing practices.

Main tasks and responsibilities:

— Assist in testing product features at all stages of development to ensure quality and functionality.

— Perform release testing for our mobile app on both Android and iOS platforms, ensuring a seamless user experience.

— Collaborate closely with Engineers to plan and execute testing strategies, identifying and resolving issues early in the development cycle.

— Work with Engineers, Designers and Product Managers to review features and provide critical feedback for improving product design and usability.

— Support the team in keeping documentation updated and maintaining a healthy, efficient test suite.

About you:

— You are experienced with manual testing of mobile applications in both Android and iOS.

— You have experience with REST API testing and a solid understanding of how applications communicate with servers.

— You are familiar with performing release testing in an agile environment with a constant release lifecycle.

— You value a good user experience.

— You enjoy collaborating closely with software engineers and you don't shy away from taking ownership of different tasks and supporting other teams.

— At Bolt, using AI daily is a baseline expectation for everyone. If there’s a faster, smarter way to do your work, we expect you to find it. You’re still responsible for the output, so the standard stays high when using AI tools.

— Experience is valuable, but what we really look for is drive, intelligence, and integrity — so if you don’t tick every box, apply anyway.
