Senior QA Engineer

Our client is a mobile gaming company shipping consumer iOS games to a global audience. Quality is a first-class concern for them — they test deep, break things early, and ship with confidence. The QA team is embedded in the product process from day one, not bolted on at the end.

About the role We are looking for an experienced QA Engineer who knows iOS mobile inside out. You will own the testing of complex game flows, validate API contracts, dig into databases, and use proxy tools to understand exactly what's happening under the hood. If you love breaking things and have the receipts to prove it, this role is for you.

Responsibilities

Design and execute test plans for iOS mobile game features (functional, regression, edge cases)

Use proxy tools (ProxyMan, Charles) to intercept and analyze network traffic

Test APIs via Postman and Swagger; validate backend responses against front-end behavior

Work directly with databases to verify data integrity and game state

File clear, reproducible bug reports and follow them through to resolution

Identify gaps in coverage and push for better testability at the product level

Integrate AI tools into QA workflows to improve coverage speed and test case generation

Requirements

5+ years of QA experience with a focus on iOS mobile apps

Hands-on experience with proxy tools (ProxyMan, Charles, or equivalent)

API testing with Postman and/or Swagger

Proficiency with database querying and management tools

Solid understanding of iOS platform behavior, OS versions, and device-specific quirks

Daily use of AI tools in QA work

English: Upper-Intermediate or higher (B2+)
