Equity: up to ~€80k
Location: Madrid (preferred) or Barcelona (1-2 office days)
Company : autonomous AI agents for enterprise clients
About the company This rapidly scaling start-up is building an AI-native platform that lets enterprise clients run high-volume operations through autonomous, conversational agents — voice, chat and messaging, deployed across dozens of countries in over 60 languages, for some of the largest employers in the world.
The company's core technical challenge is multi-agent orchestration that stays rock-solid at scale — reliable, secure and observable whether it's deployed for a healthcare provider in the US or a retailer in Latin America.
Founded by an experienced team with two prior successful exits, backed by a top-tier European VC, and already trusted by household-name enterprise customers.
About the role You'll be the most senior/founding-level engineer (working directly under the CTO/Co-Founder) owning architecture, reliability and scale for a production platform handling real-time,



high-throughput traffic. You'll stay hands-on (writing, reviewing, debugging) while setting technical direction and growing a small, high-performing engineering team.
Must have requirements: Deep backend engineering in Python — async/ASGI, Django/Channels, Celery + RabbitMQ/Redis
Proven experience building and operating high-RPS, distributed, production-grade systems
Comfort with SQL/NoSQL, cloud infra, CI/CD and production observability
Strong working knowledge of LLMs, RAG, and agentic AI systems (you don't need to have built the agents yourself, but you understand how they work and what breaks them)
A genuine "still in the code" mindset — you've led teams without stepping away from building
Previous team leading experience - at least 2-3 direct reports
Startup pace and mentality, prioritising ownership over process and titles
Exposure to conversational/voice AI infrastructure (Twilio/IVR, STT/TTS, latency optimisation)
