Primary Skill
Generative AI, fastapi, Flask
Hands-on AI Engineer who can design, build, and operationalize enterprise Agentic AI solutions. Rather than calling standard LLM APIs, you will build multi-agent ecosystems, implement cutting-edge protocol integrations (MCP, A2A, VPC), customize task-specific models, and engineer end-to-end full-stack applications with production-grade security, low latency, and cost control.
Key Responsibilities
Advanced Agent & Multi-Agent EngineeringOrchestration & Protocols
Build autonomous agents and multi-agent workflows using Model Context Protocol (MCP) for tool integration and Agent-to-Agent (A2A) protocols for task delegation.
Agent Capabilities
Design agent state management, short/long-term memory, dynamic planning, reasoning loops, and human-in-the-loop (HITL) fallback paths.
Model Optimization
Fine-tune, customize, and select models (LLMs vs. small task-specific models) based on empirical cost, latency, and accuracy metrics.
Enterprise RAG & GroundingAdvanced Retrieval
Design chunking, indexing, reranking, and hybrid search (vector + keyword) pipelines with citation enforcement.
Data Privacy
Enforce tenant isolation and RBAC boundaries to prevent unauthorized data cross-contamination.
Automated Evaluation, MLOps & Guardrails Systematic Evaluation
Build automated evaluation suites to benchmark groundedness, task completion, tool choice, safety, and agent behavior across updates.
Observability & CI/CD
Establish automated pipelines (Dev/Test/Prod), structured logging, tracing, token-cost tracking, and real-time operational alerting.
AI Guardrails
Implement active protections against prompt injection, jailbreaking, unsafe tool execution, and supply-chain vulnerabilities.
AI Security, Governance & ComplianceThreat Mitigation
Implement active guardrails against prompt injection, jailbreaking, vector store poisoning, insecure output handling, and supply-chain vulnerabilities.
Access & Data Governance
Enforce Zero-Trust architecture, identity and access management (IAM), secrets management, and secure authorization controls across APIs, agents, and tool execution.
Control Plane Controls
Develop AI control plane mechanisms, including policy enforcement, telemetry, emergency kill-switches, and automated rollback workflows
- Automated Evaluation, MLOps & GuardrailsFull-Stack & Enterprise ArchitectureEnd-to-End Application Engineering: Build responsive frontends and backend microservices using REST, GraphQL, and event-driven architectures.
Secure Enterprise Integration
Connect agents to enterprise databases, internal APIs, and Machine-to-Cloud (M2C) platforms while enforcing authorization-aware tool execution, rate limiting, and circuit breakers.
Required Qualifications
Experience
8+ years in software engineering with proven experience with at least 2+ years in hands on GenAI and AI-DLC applications to production.
Agentic Frameworks & Protocols
Deep experience with MCP, A2A, multi-agent systems, function/tool calling, VPC, taxonomy and stateful agent orchestration.
Advanced AI/ML
Demonstrated ability in fine-tuning, embedding generation, hybrid RAG, model selection trade-offs, and prompt/context engineering.
Engineering Rigor
Mastery of automated testing, secure coding (PII/PCI compliance), CI/CD, and performance troubleshooting (latency, throughput, cost).
Education
Bachelor's degree in Computer Science, Engineering, Data Science, or equivalent practical experience.
Preferred Qualifications Full-Stack & Systems
Strong hands-on proficiency in Python, modern web frontends, microservices, REST/GraphQL APIs, SQL/vector databases, containers, and cloud infrastructure.
Education
Masters degree in Computer Science, Engineering, Data Science, or equivalent practical experience.
