The ideal candidate will be an all-rounder with a passion for full-stack development, an eye for detail, and a solid understanding of databases, microservices, queuing systems, service mesh, and modern cloud architectures. Strong knowledge of design patterns such as Domain-Driven Design (DDD), Saga Pattern, CQRS, and dependency injection principles like SOLID is essential.

Key Responsibilities:

• Design and develop high-quality full-stack applications using js, Python and Next.js/React.
• Design and optimize relational databases such as MySQL and NoSQL databases like MongoDB.
• Write efficient and correct SQL queries and analyse flawed queries to improve performance.
• Create and manage indexes to optimize database performance and ensure query efficiency.
• Architect and implement Microservices-based solutions for scalable systems.
• Implement and manage Service Mesh technologies for microservices communication and network reliability.
• Apply design patterns like Domain-Driven Design (DDD), Saga Pattern, and CQRS to ensure high-quality, maintainable, and scalable software architecture.
• Utilize dependency injection and SOLID principles to promote clean code and effective software design.
• Optimize system performance using caching mechanisms (e.g., Redis, Memcached).
• Experience working with queuing tools such as RabbitMQ or Kafka for distributed messaging and event streaming.
• Contribute to DevOps practices and maintain a working knowledge of Cloud Solutions (Oracle Cloud/AWS/Azure).
• Translate complex system designs into UML diagrams and ensure effective documentation practices.
• Collaborate with product and design teams to ensure an eye for detail in both user experience and technical implementation.
• Lead and participate in R&D projects, helping to prototype and evaluate new technologies

Requirements:

• Strong js development experience.

• Expertise in designing and optimizing relational databases like MySQL and NoSQL databases such as MongoDB.
• Experience writing correct and efficient SQL queries and troubleshooting flawed queries.
• Knowledge of indexing strategies to optimize database and SQL performance.
• Expertise in developing and deploying Microservices
• Experience with Service Mesh technologies (e.g: Consul/Istio/Linkerd) for microservices management and traffic control.
• Strong understanding of design patterns such as Domain-Driven Design (DDD), Saga Pattern, CQRS, and event-driven architectures.
• Proficient in applying dependency injection and adhering to SOLID principles for maintainable software design.
• Experience with queuing tools such as RabbitMQ and Kafka for distributed messaging and event-driven architectures.
• Experience with caching mechanisms (Redis, Memcached) to enhance performance.
• Basic understanding of Cloud platforms (AWS, GCP, Azure).
• Ability to work with DevOps practices, CI/CD pipelines, and containerization (e.g., Docker).
• Proficient in UML design for software architecture and documentation.
• Detail-oriented with excellent problem-solving skills.
• Strong communication and collaboration skills within cross-functional teams.

Preferred Experience

• 5+ years of experience in full-stack development, with strong expertise in js, Python and Next.js/React.
• Prior experience with Service Mesh and large-scale system integration.
• Knowledge of Agile development methodologies such as Scrum or Kanban previous experience with JIRA and Confluence is a plus.
• Experience with R&D or innovation-focused projects is a plus.
• Familiarity with Containerization (Docker/Kubernetes).
