- Work with vector databases and relational databases to build efficient data retrieval systems.
- Design and implement REST APIs, asynchronous processing, caching, and queuing mechanisms.
- Apply software engineering best practices, including design patterns, clean code, testing, and version control.
- Deploy and maintain applications on AWS or GCP using Docker and CI/CD pipelines.
- Monitor production systems, troubleshoot issues, and improve application performance and reliability.
- Collaborate with cross-functional teams to translate business requirements into practical AI solutions.
- Contribute to code reviews, technical documentation, and knowledge sharing within the engineering team.

Required Skills

- 4–8 years of experience in software development, with solid hands-on Python expertise.

- Experience with caching, message queues, asynchronous processing, and WebSockets.
- Familiarity with AWS or GCP, Docker, Git, and CI/CD pipelines.
- Understanding of API design, system architecture, application security, and performance optimization.
- Experience testing, debugging, and maintaining production-grade applications.

Preferred Skills

- Experience building agentic AI applications and multi-agent workflows.
- Familiarity with LangChain, LangGraph, LlamaIndex, or similar frameworks.
- Knowledge of Model Context Protocol (MCP) and tool-calling mechanisms.
- Experience with LLM evaluation, hallucination reduction, and output quality monitoring.
- Familiarity with fine-tuning, model selection, and inference optimization.
- Experience with LLMOps, AI observability, and production monitoring.
- Knowledge of Kubernetes and microservices architecture.

What We’re Looking For

- Strong problem-solving and analytical skills.
- Ability to take ownership of features from development through deployment.
- Practical understanding of how to build reliable AI applications beyond prototypes.
- Ability to make sound technical decisions and explain architectural trade-offs.
