Software Development Engineer in Test

We are growing rapidly and constantly expanding our global contactless payment

ecosystem. To support this momentum, we are looking for a Software Development

Engineer in Test to play a crucial role in delivering our key software solutions. Joining a

close-knit engineering team, you will not just write tests—you will champion a quality-first

mindset from day one.

You will collaborate closely with domain owners to deliver high-quality, clean, and testable

code in line with our core strategies. This is an excellent opportunity for a dedicated SDET

who is ready to advocate for best practices, build resilient automation frameworks, and

ensure our scalable software thrives within a secure cloud infrastructure.

Responsibilities

● Design, build, and deliver sustainable, scalable, reliable, and well-tested software

into a secure cloud infrastructure.

● Advocate for and implement testing best practices across all disciplines, promoting a

quality-driven and testable mindset within the team.

● Foster a collaborative environment where everyone shares the responsibility for

quality and testing from the very outset of a project.

● Guide the team during planning and refinement sessions to accurately understand

and estimate test efforts and identify dependencies.

● Pair with Software Engineers during development and code review to ensure

appropriate test coverage at all levels and avoid any duplication of efforts.

● Develop and maintain robust tools for integration, regression, load, performance, and

security testing, ensuring our automation framework is targeted, efficient, and

resilient.

● Investigate and determine the root cause of complex issues by analyzing logs,

databases, and system behavior.

alongside mocking/stubbing, test data management, and test results reporting.

● You have hands-on experience with native Golang testing packages and UI

frameworks like Playwright. (Note: If you are proficient in another language, we will

train you as long as you are committed to learning Golang!)

● You are experienced with CI/CD pipelines, DevOps practices (including Infrastructure

as Code), and cloud platforms like GCP, alongside a strong understanding of
