Artificial Intelligence Engineer

HCL Technologies Limited; Hoboken (NJ); On-site; USD 150,000 - 210,000; Full time

Job summary

HCLTech is seeking senior engineer to design and implement loop engineering workflows using Claude Code, and to architect MCP servers and safe tool schemas for agentic development.

The role covers human-in-the-loop boundaries, CI/CD for agent-authored PRs, and mentoring staff engineers in agent-assisted software design across Java, Node.js, React, and Python tooling. Location: Hoboken, NJ; competitive compensation and benefits.

Qualifications

• Hands-on experience with Claude Code or comparable agentic coding tools in production settings.
• Strong understanding of MCP (Model Context Protocol) building and consuming MCP servers.
• Context engineering: managing context windows, prompt caching, and information architecture for long-running agent sessions.
• Awareness of prompt injection and agent-specific security risks.
• Deep experience with Java microservices.
• C4 model architecture documentation and system design.
• Node.js and Python for tooling, services, and automation.
• MongoDB schema design, performance, and scaling.

Responsibilities

• Design and implement loop engineering workflows for agentic coding.
• Architect MCP servers and safe tool schemas for LLM agents.
• Define human-in-the-loop checkpoints and rollback strategies.
• Build evaluation harnesses and observability for agent output quality.
• Design and review microservice and micro frontend architecture (C4, DDD).
• Own technical decisions across Java microservices, Node.js, React/microfrontend, and Python tooling.
• Design REST APIs and headless component architectures for humans and agents.
• Establish CI/CD practices incorporating agent-authored PRs.
• Set security practices for agentic workflows, including prompt injection risk.
• Mentor senior and staff engineers on agent-assisted development.
• Write RFCs and design docs translating problems into actionable plans.

Job description

We are HCLTech, one of the fastest-growing large tech companies in the world and home to 230,000+ people across 60 countries, supercharging progress through industry-leading capabilities centered around Digital, Engineering and Cloud.

About the Role

• Design and implement "loop engineering" workflows using Claude Code and similar tools, defining how agents plan, execute, test, and iterate on code changes
• Architect Model Context Protocol (MCP) servers and tool schemas that are legible and safe for LLM agents to use
• Define human-in-the-loop checkpoints, autonomy boundaries, and rollback strategies for agent-driven changes
• Build evaluation harnesses and observability practices to measure agent output quality and catch regressions
• Design and review microservice and micro frontend architecture using C4 diagrams and Domain-Driven Design principles
• Own technical decisions across our Java microservices, Node.js services, React/microfrontend UI, and Python tooling
• Design REST APIs and headless component architectures that support both human developers and AI agents
• Establish CI/CD practices that safely incorporate agent-authored pull requests
• Set and enforce security practices for agentic workflows, including prompt injection risk and tool-permission boundaries
• Mentor senior and staff engineers on effective agent-assisted development
• Write RFCs and design docs that translate ambiguous problems into actionable technical plans, documents that both humans and agents can act on

Required Skills & Experience

Agentic Development

• Hands-on experience with Claude Code or comparable agentic coding tools in production settings
