Solution Architect payment platform

The project is developing and integrating a modern payment platform for secure and reliable payment processing and interaction with external systems. It includes scalable microservices and asynchronous transaction processing, with a focus on resilience, security, and high availability.

• Design the target microservices architecture for banking and payment solutions
• Define service boundaries and areas of responsibility for individual components
• Design microservice communication using REST, gRPC, and Kafka
• Develop integration architectures for internal and external banking systems
• Design synchronous and asynchronous interaction scenarios
• Design solutions for high availability, scalability, and high-load requirements
• Develop and maintain architecture documentation using C4 and UML
• Define API contracts and integration interfaces
• Define approaches to API security and inter-service communication security
• Design the use of Docker and Kubernetes within the solution architecture
• Define strategies for error handling, retries, and failure recovery
• Participate in the architectural analysis of existing banking systems and integrations
• Make architectural decisions and document them in technical documentation
• Advise development teams on implementing architectural solutions
• Assess technical risks and the impact of architectural changes on the existing system

• 3+ Years of hands-on experience designing microservices architectures
• Experience designing distributed system architectures with a large number of interacting services
• Experience preparing architecture documentation, including C4 models, UML diagrams, sequence diagrams, component diagrams, and other architectural diagrams
• Hands-on experience designing REST and/or gRPC APIs
• Experience designing integration solutions between internal services and external systems
• Hands-on experience with Kafka or other message brokers
• Understanding of Event-Driven Architecture and asynchronous service communication
• Experience designing highly available and high-load systems
• Hands-on experience with Docker and Kubernetes from an architectural perspective
• Understanding of distributed systems security principles, including OAuth, TLS, authentication, authorization, and access control
• Experience designing solutions for banking, payment, or other systems with strict reliability and data consistency requirements
• Ability to analyze existing architectures, identify architectural constraints, and propose potential evolution paths
• Ability to select technologies and architectural patterns based on business requirements and technical constraints
• Experience collaborating with developers, business/system analysts, DevOps engineers, and other technical teams
