Senior QA Analyst - Mobile
Sokin
Senior QA Analyst (Mobile) - Belgrade
Role
We’re seeking a Senior QA Engineer (Mobile) to drive end-to-end quality for our mobile applications, embedding quality practices into the engineering team (“shift left”) and ensuring high-confidence releases in a regulated fintech environment.
This is a hands-on role with full ownership of mobile testing. You will be responsible for defining and driving the mobile automation strategy across iOS and Android, building the foundations of our mobile automation framework, and establishing scalable, maintainable testing practices from the ground up.
We’re looking for someone who takes true ownership — not just maintaining tests, but shaping the approach, improving coverage and reliability, and continuously raising the quality bar. You should be comfortable leveraging modern AI-assisted tools responsibly to increase testing efficiency, improve signal quality, and accelerate feedback loops.
This role requires strong collaboration skills — working closely with Mobile Engineers, Backend Engineers, Product, and other QA team members to ensure alignment, knowledge sharing, and consistent quality standards across platforms.

Key Responsibilities
Embed quality “shift-left” practices into the mobile delivery team: clarifying acceptance criteria, defining test strategy, and influencing architecture for testability and observability.
Own mobile testing end-to-end across iOS and Android applications, including functional, regression, exploratory, and automation coverage.
Design, build, and maintain scalable mobile automation frameworks for iOS and Android, establishing best practices, standards, and maintainability from the ground up.
Drive automation strategy for mobile platforms, ensuring stable CI/CD integration, reliable execution, clear reporting, and proactive flaky test management.
Validate critical fintech workflows within mobile applications such as onboarding, authentication, payments, FX conversions, approvals, reconciliations, and role-based permissions.
Validate APIs and backend services that support mobile platforms, ensuring correct integrations, authentication/authorization, error handling, and resilience.
Test non-functional requirements relevant to regulated mobile platforms: resilience, performance, offline/poor network behavior, monitoring/alerting behavior, auditability, and production readiness.
Perform and support security-focused testing activities, including validation of secure storage, session management, authentication flows, device-level considerations, and awareness of common mobile and web vulnerabilities.
Collaborate closely with Engineers, Product, Compliance/Risk, and Operations to ensure aligned quality standards and controlled releases.
Support other team members in automation best practices, promoting knowledge sharing and raising the overall quality culture within the team.
Apply AI-assisted testing pragmatically (e.g., generating test scenarios, exploratory support, log analysis, automation refactoring), while managing risks such as hallucinations, data leakage, and over-reliance.
Drive continuous improvement via root cause analysis, defect trend insights, and prevention-focused actions (not just detection).
Requirements
This role requires availability from 2:00 PM to 10:00 PM (Belgrade time) to ensure collaboration with global teams.
3–5 years of experience in mobile test automation, with strong ownership of quality outcomes in modern product teams (Senior level expectation).
Strong hands-on experience in mobile automation testing for both iOS and Android (required).
Proven experience designing and building mobile automation frameworks and establishing foundational best practices.
Experience integrating mobile automated tests into CI/CD pipelines, including reporting, gating, and flaky test triage.
Strong understanding of testing mobile application architecture, API integrations, and backend dependencies.
Strong API testing capability (REST/JSON), including negative testing and schema/contract validation.
Experience working in fintech or regulated financial services environments, understanding compliance, auditability, and release control expectations.
Experience with security testing of mobile applications, including secure storage, authentication, authorization, and common mobile/web vulnerabilities.
Familiarity with cloud environments (AWS or equivalent) and mobile test environments (real devices/emulators/simulators).
Practical use of AI in testing to improve coverage, speed, and effectiveness.
Strong collaboration and communication skills, with the ability to work cross-functionally and help elevate team practices.
Strong bonus: experience with web automation using Playwright.
