Our mission is to become the global standard for addressing. Street addresses weren’t designed for 2026. They aren’t accurate enough to specify building entrances, and they don’t exist for parks, rural areas and many parts of the world. This makes it hard to find places and causes problems and inefficiencies on a global scale.

That’s why we created what3words. We divided the world into 3m squares and gave each square a unique combination of three words. It’s the easiest way to find and share precise locations.

Over the last year, what3words has been used in 193 countries, and our monthly active users continue to grow at an impressive pace. Our tech is used by emergency services, delivery companies, eCommerce businesses, ride-hailing apps and NGOs, and is integrated into the navigation systems of millions of cars around the world.

The role:

You’ll be joining our fast-growing tech team, focusing on mobile applications for iOS, Android mobile, and integrated in-car systems. You’ll be responsible for designing and implementing robust, scalable automation in Java using Appium to ensure our mobile users have a seamless, high-performance experience.

Your rigorous attention to detail and excellent communication skills will be essential. If you are passionate about quality and have a proven competence in automating test cases for mobile applications, we’d like to hear from you.

Responsibilities:

• Build and maintain mobile test suites in Appium and CI/CD pipelines for our core applications.

• Ensure consistent functionality and UI/UX integrity across various device types, OS versions, and screen resolutions.

• Conduct a mix of manual exploration and automated regression to find and report mobile-specific bugs, from memory leaks to broken gestures.

• Collaborate with Software Engineers and Product Managers to develop effective strategies and test plans for our Mobile Apps.

• Find and isolate bugs in backend services and determine their impact on the product or release.

• Help troubleshoot issues in production and staging environments.

• Conduct post-release/post-implementation testing including regression, performance, and integration testing for backend systems.

Essential Skills:

• Mobile Automation: Experience building robust mobile automation frameworks from scratch using open-source tools (e.g., Appium, Espresso, or XCUITest), with a focus on cross-platform functional testing.

• Mobile CI/CD Integration: Experience integrating mobile automated test suites into build pipelines, specifically handling mobile-specific challenges like device clouds or emulator/simulator orchestration.

• Java Proficiency: Strong Java programming skills with expertise in JUnit or TestNG to drive mobile test scripts.

• DevOps Ecosystem: Experience with build and configuration tools such as GitHub Actions and CircleCI.

• Device & OS Savvy: A keen eye for mobile-specific nuances, including UI/UX consistency across different screen sizes, OS versions (Android/iOS), and hardware constraints.

• Soft Skills: Excellent communication in spoken and written English, paired with a high-quality "mobile-first" mindset and rigorous attention to detail.

Extra credit if you:

• Have worked with Revenue cat or other services that handle in app subscriptions for Apple’s Appstore and Android’s Play store.

• Experience working with backend services.

• Experience with BDD and implementing Cucumber for automation.

• Have worked on native frameworks (XCUITest, Espresso or UIAutomator)

• Are able to understand the business context of what you’re doing – understand the value your work creates.
