Senior AI Engineer

Overview

As a Senior AI Engineer, you'll join a 10-person team focused on data integrations (shippers and carriers moving in and out of the FourKites ecosystem) and our active AI agent workstreams — including a support automation agent handling 60-70% of customer tickets, a voice agent that calls carriers to gather and update information, and an end-to-end carrier onboarding agent (email + voice). You'll work on features end to end (~75-80% backend, ~20-25% frontend) using Python, Java/GoLang, agentic frameworks like LangGraph, React, Redis and PostgreSQL. You'll develop products that change the logistics landscape for some of the biggest corporations in the world, and work closely with our US team and customers to shape the future of the industry.

What you’ll be doing:

• Design, build, and productionize AI agents/workflows (e.g., support automation, voice, and onboarding agents) using agentic frameworks such as LangGraph
• Develop, test, and maintain backend applications in Python and Java or GoLang
• Write clean, efficient, and well-documented code across the full SDLC — development, QA, and release
• Design and implement data models and database schemas
• Collaborate with the frontend team to integrate the backend with the user interface
• Perform code reviews and ensure code quality standards are met
• Troubleshoot and debug applications, including AI agent workflows in production
• Work with the DevOps team to deploy and manage applications in production (Kubernetes)
• Continuously learn and stay up to date with new technologies and industry trends, particularly in the AI/agentic space
