About VoiceB
Por favor, presente su candidatura sin demora si su perfil encaja bien con este puesto, debido al alto nivel de interés.
We build autonomous AI voice agents that close and qualify sales for large B2C enterprises — telcos, energy providers, insurers, banks. Our agents already run live inside companies like Vodafone España and Holaluz, and we're mid-rollout across an 8-market European deployment with Alpega/Teleroute. We're a small team moving fast, and we're building the commercial engine to match the product.
The role
We're looking for a senior full stack engineer to join a small, high-ownership engineering team building the core VoiceB platform — the systems behind SuperVoice, SuperQualification, Memory, and our outcome tracking. This is a remote role for someone based in Spain, working closely with our CTO and the rest of engineering.
What you'll do
- Build and ship features across the platform: backend services, APIs, third-party integrations (Salesforce, HubSpot, Twilio, SIP/WebRTC), and internal tooling
- Own features end to end — design, build, test, deploy, monitor
- Partner directly with the CTO and founders on architecture decisions as the platform scales
- Contribute to security and compliance hardening for enterprise clients
What we're looking for
- 4+ years of full stack experience, comfortable owning features end to end on a small, fast-moving team
- Strong in a modern JS/TS stack (React/Node or similar);
comfortable with cloud infrastructure (AWS/GCP)
- Based in Spain, fully remote, able to overlap with Barcelona working hours
- Product-minded — you care about what gets built, not just how
Nice to have
- Experience with real-time or telephony systems (SIP, WebRTC, Twilio)
- Experience integrating LLMs or other AI/voice tooling into production systems
- Early-stage startup experience
What we offer
- Competitive salary + equity
- Fully remote (Spain-based)
- Direct influence over the architecture of a product still being defined
We're hiring deliberately, not urgently — we'd rather find the right person than fill the seat fast. xqbhyrx If this sounds like your kind of problem, we'd love to hear from you.
