Nice To Haves

• Experience building internal AI tools, copilots, or automation features
• Familiarity with vector databases, embeddings, or semantic search
• Experience improving retrieval quality (chunking, ranking, filtering)

Responsibilities

• Build backend services and APIs that integrate LLMs into real applications
• Develop AI-powered features using retrieval-augmented generation (RAG)
• Design scalable services using async processing, queues, and microservices patterns
• Integrate AI functionality into existing products and workflows
• Own features end-to-end: build, deploy, monitor, and improve AI functionality in production
• Solve real-world AI challenges around latency, response quality, and cost
• Work with structured and unstructured data to support AI features
