• Working closely with product management, research, and automation teams to define and deliver new capabilities
• Researching, evaluating, and adopting new technologies to accelerate product evolution
• Collaborating with multiple development teams to integrate new solutions into the existing platform

Requirements

• 6+ years of experience in backend development (Java, Go, Play Framework, Spring Boot, or similar)
• Strong experience with both relational and NoSQL databases (PostgreSQL, MySQL, MongoDB, Redis, etc.)
• Proven experience building and operating high-scale, production-grade SaaS microservices
• Solid understanding of software engineering principles, system design, and scalability
• Experience designing and implementing secure, enterprise-grade systems
• Hands-on experience with CI pipelines and service-level testing and monitoring
• Frontend experience with React and TypeScript – an advantage
• BSc. in Computer Science from a recognized university
• Highly motivated, fast learner, independent, and an excellent problem solver
