• Drive operational excellence and system reliability by actively monitoring live application metrics, dashboards, and system health to proactively detect bottlenecks and resolve production issues.
• Architect event-driven workflows and distributed systems to ensure robust, real-time synchronous and asynchronous communication across services.
• Partner with product managers, team leads, and cross-functional peers to translate complex customer service business needs into predictable, well-scoped technical deliverables.
• Adopt modern engineering practices and AI-assisted workflows to boost development velocity, optimize code delivery, and drive continuous technical improvement.

• Practical Engineering: Solid OOP, design patterns, clean code, software craftsmanship, and refactoring, domain modeling, distributed systems
• Testing Mindset: Treats testing as part of the product, not an afterthought; writes clear unit and integration tests, designs for testability, and uses CI to enforce quality
• Data Management: Experience with relational and/or non-relational systems such as PostgreSQL, Elasticsearch, MongoDB
• Event-Driven Systems: Familiarity with asynchronous messaging (Apache Kafka, RabbitMQ) for decoupled, scalable designs

• Language Skills: Good command of written and spoken English.

What We Offer

• Hybrid working model with flexibility: a schedule that helps you find the right balance between flexibility and team bonding, including work-from-abroad opportunities and a summer working model.
• Customisable FlexBenefits budget: Adjust your daily meal allowance, choose your health insurance package (and extend it to your spouse or children), and pick from additional benefits like fuel support or Trendyol shopping credits.
• Well-being support: Access to location-based in-house doctors, as well as psychologist and dietitian support, and HPV vaccination provision.
• Personalised training allowance and learning opportunities: Use your annual budget for any training or conference of your choice, explore our Learning Management System (LMS) anytime, and join in-person learning sessions offered throughout the year.
