Senior AI Engineer

About Entropik

Entropik is a Human Insights AI company helping global brands, including Fortune 500 companies, understand human emotions. Through our flagship product, Decode, we combine quantitative and qualitative research in one AI-powered platform, fortified with our patented Emotion AI tech - Facial Coding, Eye Tracking and Voice AI.

We're at an exciting inflection point, evolving from a traditional SaaS model into an Agentic AI driven company. If you want to build at the intersection of AI and human psychology, this is the place to do it.

About The Role

AI is moving fast. At Entropik, you'll be directing it at some of the most human problems in market research and customer experience.

As a Senior AI Engineer, you'll own the full lifecycle of ML and LLM-powered systems that sit at the core of Decode - from architecting RAG pipelines and multi-agent workflows to shipping production-grade inference systems for our proprietary Emotion AI models. This role is for someone who has the seniority to drive technical decisions, mentor others, and shape how AI is built at Entropik.

You'll work closely with product, research and engineering teams in a fast-moving startup environment where your decisions ship to production - not into a backlog.
