The role is open to candidates based in Gurgaon, India.
About the role
As an AI Engineer at Fluxon, you’ll take the lead in designing, building and deploying AI-powered applications for our clients.
You'll be responsible for:
- System Architecture: Design and implement end-to-end AI systems and their parts, including data ingestion, preprocessing, model inference, and output structuring
- Generative AI Development: Build and optimize RAG (Retrieval-Augmented Generation) systems and Agentic workflows using frameworks like LangChain, LangGraph, ADK (Agent Development Kit), Genkit
- Production Engineering: Deploy models to production environments (AWS/GCP/Azure) using Docker and Kubernetes, ensuring high availability and scalability
- Evaluation & Monitoring: Implement feedback loops to evaluate model performance (accuracy, hallucinations, relevance) and set up monitoring for drift in production
- Collaboration: Work closely with other engineers to integrate AI endpoints into the core product and with product managers to define AI capabilities
- Model Optimization: Fine-tune open-source models (e.g., Llama, Mistral) for specific domain tasks and optimize them for latency and cost
You'll work with technologies including:
Languages
- Python (Preferred)
- Java / C++ / Scala / R / JavaScript
AI / ML
- LangChain
- LangGraph
- Google ADK
- Genkit
- OpenAI API
- LLM - Large Language Model
- Vertex AI
Cloud & Infrastructure
- Platforms: Google Cloud Platform (GCP) or Amazon Web Services (AWS)
- Storage: Google Cloud Storage (GCS) or AWS S3
- Orchestration: Temporal, Kubernetes
Data Stores
- PostgreSQL
