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.
