You're a builder. You work 360 no silos, no handoffs. Fast-growing environments are where you do your best work. And what sets you apart is that you're an exceptional software engineer.

Health tech scale-up building voice agents that handle healthcare's phone calls. Thousands of live calls a day, where 300ms is the difference between a natural conversation and a broken one.

$30M+ raised. 60+ people across New York and Barcelona. Enterprise clients already in production.

1.The problem

Healthcare burns $1T a year on administration. Most of it is humans on hold.
Not a wrapper. Not a demo. Low-latency speech/LLM pipelines and async orchestration at scale, where failing mid-call has real consequences.

2.Stack
Python (FastAPI) · PostgreSQL · React (TypeScript) · LLMs & AI agents
Equivalents in other languages are fine.

3.You
3–5+ years shipping products end to end architecture through production
Distributed systems with async workload orchestration. This is the one that matters
Full-stack by default. No silos, no waiting for another team to own the infra
Founder mindset. The step before building your own thing
English, professionally

4. Where you might be coming from
You don't need all of these. One,



done seriously, is enough.
The academic outlier — top engineering school, olympiad medals, ICPC, or research that went somewhere
The founder — you started something. Whether it worked out is a different conversation
Big tech, ready to leave — you've shipped real things at scale and want a room where your decisions are visible
0→1 at a recognised startup — you built the thing before it had a name, users or a playbook

5.Stands out: real-time or low-latency systems in production (voice, telephony, trading, gaming, streaming). LLMs shipped, not prototyped.

6.The deal
Competitive package base + equity, aligned to seniority.
One of the most ambitious startups operating in Spain right now top-tier US VCs, YC-backed founders, and a Silicon Valley standard applied from Barcelona.
A team you'll learn from every week small, exceptionally strong, and the reason most people stay.
A product that's genuinely interesting real-time AI at the edge of what's technically possible, not a dashboard.
Barcelona office you'll actually want to be in 3–4 days on-site.
