Backend Development Engineers (Core API, Database, and Security)Are you ready to shape the foundation of a global platform that connects millions of football fans worldwide? Join OleOle, the ultimate decentralized football platform, as we build cutting-edge backend systems that deliver high-performance services, secure authentication, and seamless data management.We are seeking 4 talented Backend Development Engineers to join our team across three critical areas: Core API & Services, Database & Infrastructure, and Authentication & Security. If you're an expert in Rust and backend architecture, we'd love to have you onboard.1. Core API & Services Engineers As a Core API Engineer, you will be responsible for designing, building, and optimizing the platform’s backend services, focusing on high-performance APIs and distributed systems.Key ResponsibilitiesDevelop and maintain production-level Rust code for high-performance services.Build efficient, low-latency APIs using Rust frameworks like Actix, Rocket, or Tide.Design scalable and maintainable RESTful APIs (GraphQL knowledge is a plus).Optimize API performance using techniques like caching, load balancing, and request throttling.Develop microservices for a distributed system, integrating tools like gRPC, Kafka, or RabbitMQ.Implement secure authentication mechanisms (e.g., OAuth, JWT) and enforce API security best practices.2. Database & Infrastructure Engineer As a Database Engineer, you will ensure the scalability, integrity, and optimization of our database systems, supporting seamless data handling across the platform.Key ResponsibilitiesDesign and optimize relational and NoSQL databases (e.g., PostgreSQL, MongoDB, Cassandra).Scale databases horizontally and vertically, including partitioning, replication, and sharding.Implement caching solutions using tools like Redis or Memcached to enhance performance.Ensure data integrity, implement robust backup strategies, and prepare for disaster recovery.Manage cloud-native database solutions such as AWS RDS or GCP Cloud SQL, ensuring scalability and availability.3. Authentication & Security Engineer As a Security Engineer, you will design and implement secure authentication protocols, encryption practices, and identity management systems to safeguard our platform and user data.Key ResponsibilitiesImplement authentication protocols like OAuth2, OpenID Connect, and secure login mechanisms with JWT.Secure sensitive data using encryption techniques and ensure safe storage of credentials, tokens, and API keys.Identify and mitigate vulnerabilities such as SQL injection, XSS, and CSRF using secure coding practices.Design role-based access control (RBAC) systems and manage permission layers for user access.Conduct regular security audits and apply patches to address vulnerabilities.
