About Antai Ventures

Antai Ventures is a leading venture studio headquartered in Barcelona, with a strong presence across Southern Europe and Latin America. We team up with exceptional entrepreneurs to build disruptive, scalable companies from scratch. Since 2012, we've co-founded 30+ ventures, including Glovo, Wallapop, PlatanoMelon, and PiperAI. Collectively, our startups have raised over $1.5B in funding, generated $3B+ in shareholder value, and created 5,000+ jobs.

About Juryo

Juryo is building the agentic AI platform for small and mid-sized law firms, starting with high-volume B2C practices (extranjería, LSO, laboral, deudas, civil). Our voice and WhatsApp agents already qualify clients, generate documents, manage cases, and handle billing workflows, delivering over 2× improvement in lead conversion for our customers.

We've gone from idea to revenue in months:

  • Multiple paying law firms onboarded
  • Six-digit ARR
  • Daily usage (+200 calls/WhatsApps) by real customers
  • Clear PMF in a massive, fragmented €5B+ market (in Spain alone)

Now we're hiring our Founding Engineer. Someone relentless, hands-on, and hungry to build fast.

Why this role is special
  • Founding seat in a high-velocity applied-AI startup
  • Direct ownership of systems used daily by customers
  • Greenfield architecture and freedom to shape the tech DNA
  • Extreme autonomy, zero bureaucracy, and daily shipping
  • Your work impacts revenue and customer experience immediately
  • Opportunity to transform one of Europe's most underserved industries

If you want to build, not maintain, this is that kind of role.

What you'll do:
Build
  • Architect and ship agentic workflows across voice, WhatsApp, and email
  • Build RAG pipelines, automated document systems, and high-throughput data flows
  • Ship full-stack features end-to-end
Scale
  • Improve latency, reliability, and performance across the platform
  • Harden infrastructure to support thousands of daily agent interactions
  • Set up observability, monitoring, and deployment workflows
Own
  • Work directly with legal teams and real users
  • Turn ambiguous problems into shipped product in days
  • Drive engineering culture, best practices, and early hiring principles
  • Take full responsibility from idea design code deployment
What we're looking for:
Relentless executor
  • You move fast, unblock yourself, and thrive in high-ownership environments
  • You value speed and impact over perfect abstractions
Hands-on, end-to-end builder
  • Strong engineering fundamentals across backend, APIs, and product integration
  • Experience with LLMs, agents, or eagerness to learn extremely fast
High-agency and independent
  • You don't wait for instructions, you find problems and fix them
  • You act like an owner, not an employee
Product-driven
  • You think in terms of user value, not features
  • You enjoy deep immersion in real customer workflows
  • You iterate based on data, calls, and real transcripts
Ambitious and mission-aligned
  • You want your work to matter
  • You want meaningful equity
  • You want to help build a company from the ground up
What we offer:
  • Competitive salary
  • Meaningful equity with real upside
  • A chance to build the AI backbone for legal services
  • High-trust, high-autonomy environment
  • Based in Barcelona, in-office culture with high collaboration
  • Work on problems that touch thousands of people every week
