OleOle is seeking 4 Backend Development Engineers to shape the foundation of our global, decentralized football platform. You will build cutting-edge backend systems across three areas: Core API & Services, Database & Infrastructure, and Authentication & Security, delivering high-performance services and seamless data management.

What You'll Do

Develop 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.
Design 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.
Implement 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.

What We're Looking For

6-8 years of experience in backend development.
Strong problem-solving and collaboration skills.
Bachelor’s degree in Computer Science, Software Engineering, or equivalent experience.
Deep understanding of Rust’s ecosystem, concurrency, and memory management.
Proficiency with Rust-based frameworks like Actix, Rocket, or Tide.
Experience with distributed systems and microservice architecture.
Strong skills in database design, optimization, and scaling for both relational and NoSQL systems.
Proficiency with tools like Redis, Memcached, and cloud database solutions (e.g., AWS RDS, GCP Cloud SQL).
Expertise in implementing OAuth2, JWT, and secure login mechanisms.
Strong knowledge of encryption techniques, secure data storage, and vulnerability mitigation.
Experience designing role-based access control (RBAC) systems.
