Qualifications

• 4 - 6 years of experience in software engineering, AI engineering, cloud engineering, or backend platform development.
• Strong Python engineering capability with experience building production-grade backend systems.
• Hands-on experience building AI applications using LLM APIs, RAG systems, orchestration frameworks, or multi-agent workflows.
• Experience with LangGraph, LangChain, CrewAI, or similar agentic AI orchestration frameworks.
• Strong understanding of retrieval systems, embeddings, vector databases, reranking, chunking strategies, and AI evaluation methodologies.
• Experience deploying applications on AWS using Bedrock, SageMaker, ECS/EKS, API Gateway, Cognito, CloudWatch, IAM, Secrets Manager, and related services.
• Strong understanding of DevSecOps practices including CI/CD, infrastructure automation, testing frameworks, observability, and security hygiene.
• Familiarity with React, Node.js, streaming APIs, and modern web application integration patterns.
• Understanding of enterprise AI risks including hallucinations, prompt injection, data leakage, and operational guardrails.
• Ability to work directly with client stakeholders, delivery teams, and architecture teams in enterprise delivery environments.
• Strong debugging, problem-solving, and engineering ownership capability.

Responsibilities

• Design and deliver production-grade multi-agent systems using orchestration frameworks such as LangGraph, LangChain, CrewAI, or equivalent technologies.
• Build and maintain end-to-end RAG pipelines including chunking strategies, embedding evaluation, retrieval optimization, reranking, and hallucination evaluation.
• Develop prompt frameworks, role instructions, escalation flows, and guardrail mechanisms for enterprise AI applications.
• Implement production-grade AI guardrails including PII redaction, input sanitization, output validation, adversarial testing, and security controls.
• Design and deploy AI systems within in-region and in-VPC enterprise environments using AWS services and regulated deployment architectures.
• Build and maintain FastAPI services, streaming APIs, authentication layers, React-based interfaces, and enterprise integrations.
• Deploy and manage workloads on ECS, EKS, SageMaker, Bedrock, API Gateway, and related AWS infrastructure services.
• Implement CI/CD pipelines, automated testing workflows, infrastructure automation, observability tooling, and production monitoring frameworks.
• Define and execute testing strategies including unit testing, integration testing, retrieval testing, adversarial testing, and evaluation frameworks.
• Contribute to architecture reviews, low-level designs, solution documentation, and technical proposal responses.
• Lead technical workstreams within engagements and support junior engineering team members through reviews, debugging, and technical guidance.
• Contribute reusable engineering assets including runbooks, prompt libraries, evaluation frameworks, deployment templates, and tooling accelerators.
