We’re not building an app.

We’re building a paradigm shift in how humans and machines communicate – voice-first, privacy-conscious, and deeply personal.
Think of it as a rethink of Siri, with empathy.
Or an LLM-native assistant, that truly understands people — and respects them.
We’re a focused team of builders, engineers and entrepreneurs.

Now we’re looking for a mission-driven Fullstack Engineer who wants to shape this future with us.

What You’ll Be Building
You’ll join us in crafting a platform that enables real-time, voice-based interaction with intelligent agents – via phone, speech input or embedded voice systems.
We mix bleeding-edge tech with old-school software craftsmanship.
Our core pillars:
Conversational Depth & Structure – not just chat, but meaningful interaction
Responsible AI – local LLMs, fallback strategies, explainability
Privacy by Design – full GDPR compliance, encryption-first, user-first

Your Toolbox (and what excites you):
Modern web stack: Node.js, JS/TS, REST, WebSockets, React optional
Familiar with deploy targets like Fly.io, Railway, Vercel
You’ve touched or tinkered with LLMs, TTS/STT, prompt engineering
