A-Players

At A-Players, we’re looking for a Software Development Engineer in Test (SDET) to join our Billing Team — a team responsible for building and evolving our internal billing platform that sits at the core of the company’s financial operations.

You will take end-to-end ownership of quality in a technically complex, backend-heavy billing domain: from test strategy and automation to ensuring reliable, stable releases in a system that integrates with multiple internal and external services.

If you enjoy working close to the product and engineering, diving deep into complex domains, and building test systems that actually matter — this role is for you.

Responsibilities:

• Own and evolve QA processes within the Billing team
• Be responsible for the quality of billing-related functionality and integrations
• Design, develop, and maintain automated tests and test documentation (checklists, regression suites, test cases for automation)
• Increase transparency of QA processes and improve quality monitoring
• Identify bugs and risk areas early to improve overall system reliability
• Ensure high quality and stability of releases in a fast-moving environment

Why this role matters:

• You will work on a mission-critical financial product at the core of the company
• A large area of ownership and real impact — you will shape quality processes and automation, not just follow them
• A technically challenging domain that offers strong professional growth
• A strong engineering team and a culture of openness
• Fast decision-making and the ability to see the impact of your work quickly

What we look for:

• 3+ years of experience as an SDET / Automation Engineer / QA Engineer with a strong focus on coding in backend-oriented products
• Confident knowledge of PHP: writing automated tests, understanding backend code, and being able to work with existing codebases
• Experience designing, implementing, and maintaining automated test frameworks
• Strong understanding of test pyramid principles, testability, and maintainable test code
• Hands-on experience with API and integration test automation
• Confident work with REST APIs (Postman, Swagger, curl)
• Understanding of asynchronous processes, webhooks, and queues

Nice to have:

• Experience with financial, billing, or payment systems
• Experience testing payment orchestrators
• Knowledge of event-driven architectures
• Experience working with high-load / high-availability systems
• Understanding of 3D Secure, SCA, PSD2

Soft skills:

• Strong attention to detail and a structured approach to problem-solving
• Ability to work with uncertainty and dive deep into complex domain areas
• High level of ownership, autonomy, and responsibility
• Proactive mindset: ability to identify risks and raise them early

We offer:

• A supportive atmosphere — we’re all for creativity and providing opportunities for self-fulfillment
• Working on inspiring products in a team of supportive professionals
• A competitive salary package based on your unique expertise, skillset, and impact on the product
• Reimbursement of professional courses and trainings
• In-office, and hybrid/remote work opportunities
• Flexible working hours
• Professional equipment and access to the necessary programs
• Paid vacations, sick days, and other benefits
• Free lunches in the office
• A variety of corporate events and team-building activities
