• Apply microservice architecture patterns, including service decomposition, inter-service communication, API gateway patterns, and event-driven design.
• Design reliable data models and optimize relational database solutions using PostgreSQL; evaluate NoSQL and vector database options where appropriate.
• Implement secure application patterns, including authentication, authorization, input validation, rate limiting, and secrets management.
• Own containerized deployment practices using Docker, Kubernetes, and GKE, including production-readiness and operational support.
• Build and maintain CI/CD pipelines using GitHub Actions, Jenkins, or comparable platforms.
• Lead practical integration of LLMs into production applications, including prompt engineering, retrieval-augmented generation, embeddings, and model evaluation practices.
• Mentor engineers, guide technical delivery, and partner with business stakeholders to translate requirements into effective technical solutions.

Required Qualifications

• 8+ years of software development experience in enterprise-scale or production environments.
• Demonstrated full-stack development capability, including React with TypeScript on the frontend and FastAPI, Spring Boot, or comparable backend frameworks.
• Proven experience designing, developing, and operating RESTful APIs and microservices at scale.
• Strong understanding of microservice architecture patterns, including service decomposition, inter-service communication using REST, gRPC, or message queues, and API gateway patterns.
• Experience implementing event-driven architectures and asynchronous messaging platforms such as Kafka, Pub/Sub, or similar technologies.
• Hands-on database design experience with PostgreSQL, including relational schema design and query optimization; exposure to NoSQL or vector databases is preferred.
• Working knowledge of authentication and authorization patterns, including OAuth2, JWT, and role-based access control.
• Strong understanding of API security best practices, including input validation, rate limiting, and secrets management.
• Experience with Docker and Kubernetes/GKE for containerization and orchestration.
• Experience with CI/CD pipelines using GitHub Actions, Jenkins, or similar platforms, including ownership of the full pipeline lifecycle.
• Hands-on Google Cloud Platform experience with GKE, Cloud Functions, BigQuery, and related services; Azure experience is a plus.
• Experience working in Agile/Scrum development environments.
