About Us
We're building the AI workforce for Spanish trades — climatización, fontanería, electricidad, solar. We answer calls, handle WhatsApp, and book jobs directly into the operator's CRM. One HVAC operator deployed in Catalonia, ten more by year-end.
The category just got real: ElevenLabs opened a Madrid office last week, HeyDiga raised €1M from KFund in December, and Avoca raised $125M at a $1B valuation building this in the US. The Spanish trades vertical is a nine-month window. I'm hiring the engineer who closes it with me.
The Role
You'll own engineering end-to-end, starting as Founding Engineer with a clear path to CTO as we hire under you. Concretely:
- Telephony + WhatsApp infrastructure. Telnyx/Twilio integration, SIP trunking, number porting from Movistar/Vodafone/MasOrange without service interruption. WhatsApp Business API onboarding via 360dialog. Multi-channel orchestration so calls, WhatsApp, and Google Business share one conversation context. Production voice via ElevenLabs/Deepgram/OpenAI Realtime — sub-second latency, regional accents.
- Spanish CRM integrations. Native Holded, STEL Order, Praktiko. Not Zapier glue. The endgame is being the official AI receptionist inside their marketplaces.
- Security and AI quality tooling. GDPR, EU data residency, ENS Nivel Alto from day one. Plus the internal tooling that lets a small team obsess over every customer's call quality — today that's you and me listening to recordings and tuning prompts; over time it becomes a structured ops function we build together.
- Hiring. Bringing on engineers as the customer base grows.
The bottleneck right now is onboarding speed. Today it takes two weeks to launch a customer; it should take two hours. Closing that gap is the next twenty deals.
Who You Probably Are
- 5–10 years shipping production systems, with at least one early-stage startup stretch
- You've shipped CPaaS in production: Twilio, Telnyx, MessageBird, Sinch, or similar. SIP, RTP, webhooks, and call control are not abstract concepts to you
- You've onboarded WhatsApp Business API through a BSP — Meta verification, template approvals, WABA migrations. If you haven't, this isn't the role
- You've shipped real-time LLM applications: latency budgets, streaming, function calling, RAG
- You're AI-native in your own workflow. Claude Code, Cursor, or equivalent is how you ship. You operate as if AI tooling makes you 3–5x more effective, because it does
- You speak fluent Spanish. Catalan a plus
- Based in Spain, fully remote, but willing to spend one to two weeks at a stretch on-site with customers during onboarding. The first ten customers are won by embedding deeply with them
Ideally you come from companies like Twilio, MessageBird, 360dialog, Sinch, TalkDesk, Zadarma, Voiped, Landbot, Vox AI, ManyContacts, Holded, Factorial, TravelPerk, or Typeform. The work done, and the time committed matters more than the logos though.
Compensation
- Base: €50k, scaling up as we grow
- Equity: 1–2.5%, four-year vest, one-year cliff. True co-founder package available for the right person
- Spanish private healthcare, equipment, learning budget, equity refresh at Series A
Self-Screening Question
Before you apply, ask yourself: how would you onboard a Spanish HVAC company with an existing Movistar landline, an existing WhatsApp Business app on the owner's personal number, and three receptionists who can't lose a single call during the migration? If that question makes you smile because you've lived something like it, we should talk.
How to Apply
Email [email protected] with:
- CV or LinkedIn
- One paragraph on a telephony or WhatsApp integration you've shipped in production — what was hard, what would you do differently
- One paragraph on how AI tooling shows up in your day-to-day engineering work
Please answer in Castellano or Catalan.
Process: a technical conversation, a conversation about how you'd work directly with a non-technical Spanish HVAC owner. About six hours total. Decision and offer within two weeks of first contact. I respond personally within five business days.
