Descripción del empleo

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

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.
