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

• 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.
• 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.
• 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.
• 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)
• 👶 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)

What You’ll Do
As part of the Kotlin Compiler team, you’ll take ownership of the central pipeline that connects the compiler’s frontend with multiple backends. This is deep, technical work that directly influences how Kotlin code is transformed, validated, and optimized. You’ll make architectural decisions that improve compiler performance and memory usage without sacrificing backward compatibility. Working closely with other Kotlin teams, your efforts will shape the evolution of the language and improve the daily experience for Kotlin developers worldwide.

Day To Day, You Will

• Develop and implement new language features.
• Implement and fine-tune intermediate representation (IR) lowering passes.
• Investigate and resolve complex compiler bugs and edge cases.
• Improve compiler performance and memory usage.
• Work with other Kotlin teams to shape how the language evolves.
• Help improve the developer experience for Kotlin users.
• Maintain and improve Kotlin infrastructure (IR/AST transformations, Klibs, and its backward compatibility).

What You’ll Bring

• Precision. You care about every detail – from clean architecture to edge cases.
• A strong sense of ownership. You’re comfortable taking on complex technical challenges.
• Clear communication. You can explain your thinking and justify your technical decisions to other experts.
• A collaborative mindset. You work well with teammates to find the best solutions.
• A long-term focus on quality. You prioritize maintainability and backward compatibility over quick fixes.

What You’ll Need

• Proficiency in developing with Kotlin/JVM or Java.
• A deep understanding of algorithms and data structures.
• The proven ability to write clean, maintainable, and well-tested code.
• Experience in compiler development would be a definite plus.
• Experience developing Gradle plugins would be advantageous.
• Demonstrated success in optimizing JVM application performance would also be a plus.

What Success Looks Like
In your first few months, you’ll dive into the compiler's central pipeline and start taking ownership of specific lowering passes and bug fixes. Over time, you’ll be making significant architectural contributions that measurably improve compiler performance and memory usage. Success means earning the trust of your team through clear communication, well-reasoned decisions, and code that leaves the Kotlin compiler cleaner and more robust than you found it.

Why join JetBrains?

• Strong base salary. We offer competitive pay that reflects your skills and experience.
• Flexible work location. Enjoy the freedom to work from home or from the office.
• Remote work. Spend up to 30 days per year working remotely from abroad.
• Extra time off. More days to relax, recharge, and do the things you love.
• Medical insurance allowance. Enjoy peace of mind for you and your family
• Learning and development opportunities. Access to conferences, courses, and language classes.
• Relocation support. We help make your move as smooth and stress-free as possible.
• Language classes. Pick up the local language or sharpen your English skills.
• Fuel your day. Enjoy a hot meal or receive a lunch allowance on workdays.
• Mental health support. To help you feel your best, we provide easy access to professional mental health services.
• Sports benefit. Enjoy an on-site gym or sports club stipend.
• Internal events. Join company-wide celebrations and team gatherings.
• Some benefits may vary depending on location.
