- Design and maintain a microservices architecture focused on high performance, scalability, and reliability.
- Develop GraphQL APIs for efficient frontend-backend communication.
- Ensure data integrity and implement advanced features like time-series database integration, effective caching, and asynchronous processing through message queues.
- Deeply understand and apply distributed system design, utilizing contemporary technologies and methodologies.
- Implement robust caching mechanisms for platform performance optimization.
- Manage and integrate AWS services to construct a resilient cloud infrastructure.
- Uphold high security standards, including implementing OAuth 2.0 for secure authentication.
- Collaborate with cross-functional teams to foster rapid and agile development cycles.
Requirements
- Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.
- At least 5 years of backend development experience, with a strong emphasis on building scalable and resilient systems.
- Proficiency in blockchain technologies, with a focus on payment systems.
- Demonstrated experience in developing and managing APIs, preferably with an API-first approach.
- Proficient in designing, developing, and maintaining microservices architecture. Experience with containerization (e.g., Docker) and orchestration tools (e.g., Kubernetes) is highly desirable.
- Extensive experience with cloud services, particularly AWS (including Lambda, RDS, ECS/Fargate, etc.), and understanding of cloud-native development practices.
- Proficiency in Node.js and GraphQL. Knowledge of other relevant programming languages and frameworks is a plus.
- Solid grasp of PostgreSQL and experience in managing data in a distributed, microservices environment.
- Familiarity with security protocols and standards, especially OAuth 2.0, and understanding of security best practices in API development and microservices.
- A minimum of 3 years of experience in the fintech sector, particularly in payment processing. Understanding of payment gateway integration and compliance standards (like PCI DSS).
- In-depth knowledge of distributed systems, data consistency models, and message queue systems (e.g., Kafka, RabbitMQ).
- Exceptional problem-solving abilities and strong teamwork orientation. Excellent communication skills for effective cross-functional collaboration.
