Senior Software Engineer (Kotlin / Tooling / Testing)

Adyen provides payments, data, and financial products in a single solution for customers like Meta, Uber, H&M, and Microsoft - making us the financial technology platform of choice. At Adyen, everything we do is engineered for ambition.

For our teams, we create an environment with opportunities for our people to succeed, backed by the culture and support to ensure they are enabled to truly own their careers. We are motivated individuals who tackle unique technical challenges at scale and solve them as a team. Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster.

As a Senior Software Engineer, you’ll play a critical role in scoping and developing testing tools used by all teams working on our Payment Terminals Firmware. Our goal is to ensure maximum reliability of our products by providing the right testing frameworks to the rest of the engineering organization.

What You’ll Do

Adyen launches new features at a high pace, making the automated execution of test cases critical to the success of releases and the rollout of new features and fixes. We use multiple testing frameworks, each dedicated to different terminal models, phases of the release process (pre-merge, post-merge), and levels of automation.

One of these frameworks is based on our in-house build robots, allowing us to control 50+ robots to perform thousands of different E2E test scenarios on various payment devices. Other frameworks involve emulating terminals (fully or partially) or remote controlling actual terminals installed in a “device farm”.

In this role, you will:

• Understand the real needs of our developers.
• Identify areas of improvement in existing frameworks.
• Build new frameworks and/or harmonize existing ones to improve the developers’ experience.
• Develop components and APIs for writing test scenarios.
• Create mechanisms for scheduling tests, reading test results, reviewing logs, and managing different configurations of the terminals.
• You’ll be part of a young and motivated team with a lot of room to start new initiatives and take ownership.

You are a seasoned software engineer with extensive experience in software development, particularly in testing and tooling. Your years of hands-on development have made you acutely aware of the needs and importance of the developer experience when using such tools. You have a deep passion for developing innovative testing solutions and are driven to set new industry standards. You thrive in challenging environments and are eager to make a significant impact on the tooling landscape within IPP. This role requires a strong development background and a strategic vision for testing.

• Experienced with Kotlin/Java (5+ years combined) and have experience/interest in testing tools available for Android.

Our business and technical challenges are unique, we need as many different voices as possible to join us in solving them - voices like yours. So no matter where you’re from, who you love, or what you believe in, we welcome you to be your true self at Adyen.
