AI Senior Fullstack Engineer (Remote) at Contentsquare | Build the Future of AI-Powered Digital Experiences
Artificial Intelligence is reshaping how businesses understand and improve customer experiences. Companies are increasingly integrating Large Language Models (LLMs) into their products to deliver smarter insights, automate workflows, and make complex analytics accessible to everyone. As a result, experienced full-stack engineers with AI product development skills are among the most sought-after professionals in the technology industry.
Contentsquare is hiring an AI Senior Fullstack Engineer to join its Applied AI team. This full-time remote opportunity is ideal for experienced software engineers who enjoy building production-ready AI features using modern web technologies such as TypeScript, Node.js, React, and Vue, while leveraging Large Language Models to create innovative customer experiences.
About Contentsquare
Contentsquare is a global leader in digital experience analytics. Its Experience Intelligence platform helps organizations understand how customers interact with websites and mobile applications, enabling businesses to improve user experiences through actionable insights.
Following its acquisition of Heap, Contentsquare has expanded its AI-powered analytics capabilities, helping organizations answer complex questions about digital journeys through conversational AI and intelligent automation. The company serves thousands of customers worldwide and operates across multiple countries with a distributed workforce.
About the AI Senior Fullstack Engineer Role
This is a software engineering position focused on building AI-powered product features rather than developing machine learning models from scratch.
You'll work on innovative projects that integrate Large Language Models (LLMs) into Contentsquare's products. One major initiative involves expanding the company's AI Copilot experience, allowing users to ask natural-language questions and receive meaningful insights about customer behavior without requiring advanced analytics expertise.
The engineering team operates like a startup within the company, moving rapidly from ideas to prototypes, customer validation, and production deployment. Engineers are encouraged to participate in user interviews and contribute directly to product discovery.
