- Design microservices, distributed systems, REST APIs, and event-driven architectures using the Controller-Service-Repository pattern.

- Apply strong software design principles, design patterns, and architectural best practices to build clean, maintainable, and extensible code.

Hands-on Development :

- Build enterprise applications using Java, Spring Boot, PostgreSQL, and Kafka on Linux environments.

- Integrate with third-party systems, enterprise platforms, messaging systems, and complex API ecosystems.

- Contribute to Kubernetes-based, containerized, cloud-native deployments with CI/CD pipelines and observability built in.

Performance & Reliability :

- Drive performance optimization, caching strategies, database optimization, scalability, and resilient system design.

- Lead debugging and troubleshooting across application, database, messaging, and infrastructure layers using root cause analysis.

- Establish monitoring, logging, and alerting practices to maintain system reliability in production.

Delivery & Collaboration :

- Evaluate technical feasibility, build proof-of-concepts, and independently drive projects from design through production deployment.

- Mentor engineers, conduct code and design reviews, and produce high-quality technical documentation.

- Collaborate effectively with cross-functional teams to align priorities and ensure cohesive delivery.

Qualifications :

Education :

- Computer Science or related degree, or a combination of education and relevant experience.

Experience :

- 8+ years of software development experience with hands-on backend engineering.

- Experience with microservices, REST APIs, and event-driven architecture.

- Proficiency with containerization and orchestration (Kubernetes, Docker).

- Understanding of CI/CD pipelines and cloud-native deployment practices.

- Practical experience with performance tuning, caching, and database optimization.

- Familiarity with AI-powered engineering tools (e.g. GitHub Copilot, Claude Code, Cursor) is a plus.

Soft Skills :

- Ability to communicate technical concepts clearly to technical and non-technical stakeholders.

- Strong ownership mindset able to independently drive a project from design to deployment.

- Ability to mentor and elevate the engineering skills of peers.

- Strong analytical, prioritization, and time management skills.

- Comfortable operating in a fast-paced, high-stakes production environment.
