• Build and optimize prompt workflows, embeddings, semantic search, and Retrieval-Augmented Generation (RAG) solutions.
• Implement document-processing pipelines using chunking, segmentation, tokenization, and metadata enrichment techniques.
• Design and optimize different document chunking strategies, including fixed-size, recursive, semantic, and context-aware chunking, based on data type and use case.
• Develop and maintain RESTful APIs and event-driven microservices.
• Design scalable and reliable backend services using microservices architecture.
• Package and deploy applications using Docker and container orchestration platforms such as ECS/EKS where applicable.
• Develop and maintain CI/CD pipelines for automated testing, deployment, and release management.
• Monitor application performance and troubleshoot production issues to improve reliability, scalability, and performance.
• Follow secure coding practices and AWS best practices for IAM, access control, logging, monitoring, and application security.

Preferred Candidate Profile

• Strong problem-solving and analytical skills.
• Good understanding of enterprise application development.
• Ability to work independently as well as collaborate with cross-functional teams.
• Good communication skills.
• Willingness to learn and work with emerging AI technologies.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
