Interhuman AI builds social intelligence infrastructure that makes AI systems capable of understanding human behavior. Our API detects and interprets behavioral signals like hesitation, engagement, confusion, interest - across voice, facial expressions, body language, and words.

We’re now looking for a Frontend Developer to shape how developers experience Interhuman - from the first interaction in the playground to integrating our SDKs in their own products.

About the Role

You’ll own the developer experience layer of Interhuman - the playground, demos, and SDK touch points that make our technology tangible. You’ll turn our API into interactive interfaces that help developers understand, integrate, and experiment fast.

This is a hands-on coding role and you should care deeply about polish, motion, and how details shape the feel of a product. You’ll work closely with product, backend, and DevRel to make sure Interhuman feels intuitive from day one.

What you’ll do

• Build and own our Playground – the central interface where developers experiment with our models, configure parameters, and test real-time outputs.

• Design and implement onboarding flows that make it effortless for developers to go from “first try” to “first integration.”

• Develop SDK example apps and reference implementations (React, JS, Python) that live on GitHub.

• Build interactive demos for pilots and launches that showcase specific use cases (e.g. sales coach, engagement detector, emotion-aware avatar).

• Integrate frontend with API endpoints and real-time model streams (REST, WebSocket, WebRTC).

• Add refinement and clarity with micro-interactions, transitions, and animations using Motion.dev, GSAP, or similar.

• Contribute to DX tooling and infrastructure - helping shape the workflow for external developers.

• Work closely with DevRel to capture developer feedback and translate it into UX improvements in the playground and SDK.

• Collaborate with product and UX to make every interaction feel modern, confident, and human.

Who you are

• 3-6 years of experience as a Frontend Engineer building production web applications.

• Strong in React / Next.js, TypeScript, Tailwind.

• Comfortable integrating APIs and working with real-time or streaming data.

• Attention to interaction details and design quality (motion, rhythm, spacing).

• Experience with animation frameworks (Framer Motion, GSAP, Rive or similar).

• Excited about building developer-facing products

• Curious about AI and how humans and machines interact.

• Comfortable shipping fast and clean in early-stage environments.

Bonus if:

• You’ve built developer platforms, SDKs, or playgrounds before

• You have experience with data visualization, creative tech, or 3D (Three.js / WebGL)

• You’ve contributed to OSS projects or maintain your own demo repos.

Why join

• You’ll define how developers experience human-aware AI - from playground to integration.

• Work directly with founders on a product that merges deep tech and design.

• Freedom to prototype, experiment, and ship at high speed.

• A culture where craft matters - every detail counts.

Who we are

At Interhuman AI, we’re building social intelligence for AI. Our mission is to enable machines to understand how humans actually behave – not just what we say. We’re pioneering a new class of multimodal AI that reads facial expressions, voice, and body language to interpret social signals, delivering AI interactions that feel truly adaptive and emotionally aware.

We’re a small but ambitious team (backed by top investors) with a working prototype, and a vision to become essential infrastructure in the future of conversational AI. We value curiosity, high standards, and collaboration – and we also believe in keeping things fun and supportive.
