• Solid knowledge of Linux, and proficient command-line skills (Bash/Shell)
• Solid knowledge of Docker and Kubernetes for deploying and scaling containerized applications
• Experience with Relational Databases (PostgreSQL), including query optimization and schema design
• Experience with Redis for caching and state management in distributed systems
• Familiarity with the ELK Stack (Elasticsearch, Logstash, Kibana) for logging, monitoring, and observability
• English proficiency at an Intermediate level or higher

Nice to have

• Experience with Vector Databases (e.g., pgvector, Milvus, Qdrant) and semantic search optimization
• Experience implementing Model Context Protocol (MCP) or similar interoperability standards
• Understanding of distributed application principles and microservice architecture
• Familiarity with modern back-end design patterns
• Experience in fields where data security and integrity are paramount
