About the position:

• Work as part of a team to design, build, and maintain high-performance backend services in a microservices environment.
• Take ownership of complex features and systems, from design through implementation.
• Optimize data collection pipelines and backend systems for scalability and efficiency.
• Continuously learn, evaluate, and adopt new technologies and methodologies to improve our products and architecture.

Requirements:

• At least 4 years of relevant experience as a backend engineer.
• Strong experience with an object-oriented programming language (C#, Java, etc.).
• Proven experience building and maintaining microservices-based architectures.
• Solid understanding of backend architectures, distributed systems, and data handling at scale.
• Sense of ownership, responsibility, and the ability to work well in a team.
