Middle Manual QA Engineer (Mobile)

You will join a fast-paced environment with a strong, battle-tested dev team that has already scaled products to millions. Here, you will own product initiatives that directly impact a massive audience, make decisions that shape how people connect globally, and work on big problems with smart, innovative solutions, all with real ownership of outcomes.

About your role: As a Manual QA Engineer on our iOS team, you will join a freshly launched product right at the moment of its active growth. Your work will directly shape release stability, regression coverage and the way quality is built into the product as it scales. You will own features from requirements to release, go far beyond UI testing into databases, APIs and real client–server traffic, and test the logic that directly drives revenue: in-app purchases, A/B experiments and analytics. And you will do it with an AI-assisted QA toolset that you can use and grow from day one.
