AI Integration Engineer

AI Integration Engineer

Location: Remote (Costa Rica)

Employment Type: Independent Contractor, 4 months.

About the Role

We are looking for a motivated and detail-oriented AI Integration Engineer to join our client's team in the construction-planning SaaS sector. In this role, you will contribute to designing and implementing the Claude integration using Anthropic's tool-calling APIs, building and embedding the front-end intent interface, and implementing strict per-user, per-tenant context isolation.

Responsibilities

• Design and implement the Claude integration using Anthropic's tool-calling APIs, with LangChain or LangGraph for orchestration where appropriate.
• Build and embed the front-end intent interface (command bar/panel) into the existing Angular TypeScript application without deep entanglement with the core product.
• Implement strict per-user, per-tenant context isolation to ensure no customer's data is accessible to another.
• Build the plan → preview → confirm → execute interaction flow: Claude proposes actions, the user reviews and approves, and the app executes through existing REST APIs.
• Conduct exploratory POC work to validate that Claude can reliably accomplish specific intended tasks with the available data before committing to full implementation.
• Use Claude Code as your primary development assistant throughout the build cycle.

Requirements

• Angular TypeScript — production-level front-end experience
• Anthropic Claude / LLM integration — real shipped experience, not just demos
• Tool-calling / agentic patterns — LLM-as-planner, typed tool registries
• Multi-tenant context isolation — scoping LLM context per user/tenant
• REST API integration — consuming and reasoning about existing endpoints
• Claude Code — active daily use in development workflow
• Strong professional English — written and spoken, client-facing

Preferred Qualifications

• LangChain / LangGraph — orchestration of multi-step agentic flows
• Prompt engineering, eval harnesses, regression testing for LLM behavior
• Node.js / server-side TypeScript (for orchestration layer)
• Structured output validation (Zod, JSON Schema)
• Construction or field-operations domain familiarity
• Spanish fluency (working language with the broader team)
