Role Overview

We are seeking a highly skilled and proactive Mobile QA Engineer (Hybrid Manual & Automation) to join our growing engineering team as our first dedicated Mobile QA specialist. In this position, you will be joining an established, collaborative QA department.

Your primary mandate will be to establish the fundamentals of mobile quality and build a scalable mobile test automation framework specifically for our iOS and Android applications. Rather than rewriting our existing processes, you will focus on developing mobile-specific protocols and test frameworks that integrate with and enhance our existing QA ecosystem, test suites, and continuous delivery pipelines.

The ideal candidate is someone who can balance hands-on manual exploratory testing to protect immediate mobile releases with programmatic automation engineering to drive long-term mobile regression velocity.

Duties and Responsibilities:

1. Mobile QA Process Ownership & Integration

• Act as the first dedicated Mobile QA specialist in the organization, taking ownership of the testing lifecycle for our iOS and Android applications.
• Design and execute comprehensive mobile-specific testing strategies, test plans, and test scenarios.
• Collaborate closely with our existing team of 24 QA engineers to ensure that mobile testing standards align with, enhance, and scale alongside the broader company quality framework.
• Review business requirements, mobile designs, and technical specifications during Agile ceremonies to identify potential issues early and establish clear acceptance criteria.

2. Manual & Exploratory Diagnostics

• Execute manual functional, regression, and exploratory testing on physical devices and emulators/simulators to discover edge cases and usability issues.
• Reproduce, isolate, and log detailed bugs, providing developers with precise steps to reproduce, screenshots, videos, and native system/network logs.
• Validate native device interactions, gestures (swiping, pinching, tapping), and application behaviors under variable network profiles and system interrupts.

3. Mobile Automation Framework Engineering

• Build, configure, and expand our mobile test automation framework from the ground up to support both iOS and Android applications.
• Architect a clean, modular page-object framework that enhances our current test coverage and supports automated regression runs.
• Integrate mobile automated suites into our existing continuous delivery (CI/CD) pipelines and debug failed deployments.

4. API & Backend Validation

• Execute API testing including writing validation scripts to verify backend data and service integrations.
• Validate backend database structures and client-server data synchronization.

Qualifications and Experience:

Must-Have Qualifications:

• Experience: 3+ years of professional software QA experience, demonstrating a strong track record handling both manual execution and test automation.
• Mobile Expertise: Mandatory hands-on experience in validating native mobile applications on both iOS and Android platforms.
• Automation Tooling: Solid experience writing and maintaining automated UI scripts using Appium combined with JavaScript or TypeScript.
• Organizational Collaboration: Experience working within an established QA department and collaborating with multi-functional teams (developers, product managers, and UI/UX designers).
• API Testing: Proven proficiency with API verification using tools like Postman, Charles Proxy, or automated API testing libraries.
• CI/CD Pipelines: Experience integrating automated test runs into continuous integration pipelines and investigating broken builds.

Nice-to-Have Qualifications:

• Experience running tests at scale on cloud-based physical device farms (e.g., BrowserStack, LambdaTest, or AWS Device Farm).
• Experience analyzing mobile app performance and exceptions using platforms like Firebase Crashlytics.
• Practical familiarity with or interest in utilizing AI-powered tools for test acceleration and code debugging.

What We Offer

• Choice of work equipment (e.g., laptop, monitor, etc.)
• English classes (iTalki – $130 monthly)
• Flexible schedule (we usually work between 09:00/10:00 and 18:00/19:00 CET or EET)
• Newborn bonus (€500 per child)
• Patent remuneration
• Paid leave
• Remote work in locations without our offices
• Hybrid work in locations with offices (2 days in-office, 3 days remote)

Constructor fosters equal opportunity for people of all backgrounds and identities. We are led by a gender-balanced board committed to building a diverse and inclusive organisation where everyone can become their best self.
