About Us At Entropik, we're redefining how the world understands people. As a Human Insights AI company, we help global brands decode what their customers truly think and feel, not just what they say. Our platform combines quantitative and qualitative research with patented Emotion AI technologies: Facial Coding, Eye Tracking, and Voice AI. The result? Faster decisions, richer insights, and research that's finally free from human bias.

We're building the future of market research, and we want engineers who want to build things that matter.

Why Entropik You'll be working on genuinely novel technology - Emotion AI is a space most engineers never get to touch. Our customers are global brands making high-stakes product and marketing decisions, and your work will directly shape the quality of those decisions.

The Role We're looking for a Senior Fullstack Engineer (React + Python), who's equally comfortable architecting backend systems and crafting polished front-end experiences. You'll work on a product that sits at the intersection of AI, research, and human psychology, touching everything from real-time data pipelines to the interfaces researchers use every day.

This isn't a role where you'll be handed a spec and told to execute. You'll help shape how we build.

What You'll Do

Build and maintain responsive, high-performance web applications using modern front-end frameworks - with a strong eye for usability, accessibility, and polish
Design and scale backend systems using Python, AWS, and NoSQL databases that hold up as our product grows
Define and own architectural decisions, setting the bar for coding standards and best practices across the team
Build and refine RESTful APIs and microservices, and work with cloud-native and serverless architectures on AWS
Leverage API Gateways and smart API management patterns to keep our integrations clean and reliable
Mentor engineers around you - sharing context, unblocking challenges, and raising the overall quality of the team's work
Write technical documentation that actually gets read and used

What We're Looking For

3-6 years of professional fullstack development experience
Strong command of the modern JavaScript ecosystem — React, TypeScript, Material-UI, Webpack, ESLint, Jest
Backend experience in Python, Java, or Node.js, with solid understanding of microservices, SOA, and REST APIs (we work primarily in Python, so comfort there matters)
Fluency in OOP and functional programming, clean code principles, and React design patterns
Hands-on experience with SQL and NoSQL databases — Postgres, MySQL, Elasticsearch
Cloud platform experience, ideally AWS or Azure
Experience building scalable products in fast-moving environments
Comfort with Agile methodologies and iterative delivery
