Work Experience

We are looking for a Senior AI Engineer with strong software engineering fundamentals and a clear AI‑first, automation‑driven mindset. The ideal candidate will have deep hands‑on experience building production‑grade Generative AI and Agentic AI systems, and will naturally default to AI‑driven automation rather than manual, rule‑based, or UI‑heavy solutions.

This role focuses on designing, building, and operating scalable AI systems on AWS, applying sound engineering practices across the full SDLC.

Generative AI & Retrieval‑Augmented Generation (RAG)

· Design and implement LLM‑based solutions for real‑world, production use cases.

Apply deep hands‑on expertise in:

o Prompt engineering

Chunking strategies for unstructured data
Embeddings and vector databases
Retrieval‑Augmented Generation (RAG)
Graph RAG (knowledge graphs combined with vector search).
Ensure AI systems are robust, explainable, and production‑ready.

Agentic AI & Workflow Automation

· Build Agentic AI systems capable of planning, reasoning, and executing multi‑step workflows.

Implement tool and function calling, context management, and memory strategies for agents.
Design systems where agents orchestrate workflows and LLMs act as reasoning and decision layers.
Identify opportunities to replace manual or rule‑based processes with AI‑driven automation.

Cloud‑Native AI Platforms & AWS

· Build and deploy AI services on AWS using cloud‑native patterns.

Work hands‑on with AWS services such as:

o EC2, Lambda, ECS, EKS

DynamoDB, RDS (PostgreSQL/MySQL), MongoDB
IAM, VPC, S3, EBS, CloudFront, Route 53.
Leverage AWS Bedrock (Agents, Knowledge Bases) and Amazon SageMaker to operationalize AI solutions.

Containers, DevOps & CI/CD

· Containerize AI services using Docker and deploy using Kubernetes (EKS).

Integrate services into CI/CD pipelines using GitHub or GitLab.
Manage infrastructure using Infrastructure as Code (Terraform).
Ensure stable, repeatable deployments in Linux environments.

Application Integration (Good to Have)

· Contribute to backend or application integration when required:

o Backend: Python (Flask) or Node.js (Express)

Frontend: React or Angular.
Integrate AI services with existing applications using APIs or events.
UI and full‑stack work is supportive, not a primary responsibility.

Required Skills & Qualifications

· 5+ years of experience in Software Engineering or AI Engineering.

Strong software engineering skills with proven experience building production systems.
Strong programming experience in Python.
Hands‑on experience with:

o Generative AI and Large Language Models

RAG pipelines, embeddings, and vector databases
Agentic AI workflows and systems.
Solid understanding of:

o System design

Microservices and distributed systems.
Experience deploying and operating systems on AWS.
Comfortable working in Agile environments and Linux systems.

Good to Have

· Full‑stack development experience (React/Angular, Flask/Node.js)

Knowledge graph experience
MLOps exposure
Experience working within enterprise AI governance frameworks

SSE - Python + AWS + GenAI + Microservices/REST API
