Conversations beat CVs.
That's the conviction behind Hirevoice.
Our AI interviewer gives every candidate a real shot at showing how good they are — and gives employers signal they can actually trust.
But we're building more than an interviewer: an enterprise AI platform.
Co-founded by Nacho González-Barros (founder of Info Jobs & Hireflix).
General and enterprise (current average ARR per costumer: 100k) from day one.
Well-funded by a tier-1 VC and 10+ business angels with exits under their belt.
We're building an enterprise AI platform that stays startup?fast, with minimal bureaucracy.
We've already achieved product-market fit.
About us: Your mission: build the technical backbone of that platform — robust without getting slow, compliant without getting heavy, customizable without fragmenting, AI-agent-native from day one.
Key Responsibilities Build an enterprise AI interviewing platform capable of absorbing client-by-client variation without fragmenting or losing development speed.
Turn specific client needs into reusable platform capabilities — no per-client hacks,



no parallel product branches.
Design a technical foundation that lets you iterate fast with confidence: critical flows tested, real observability, safe releases, and errors surfaced before the client sees them.
Integrate compliance, modular architecture, and scalable integrations as part of the system's core — not as layers bolted on at the end.
Leverage AI agents across development, QA, debugging, triage, incident response, documentation, and refactoring to multiply the team's capacity.
Shrink the latency between a signal in production and a deployed fix through better feedback loops, tooling, and software operations.
Lead technically from a hands-on position — making architecture, infrastructure, and product decisions with an enterprise-platform mindset.
Think in abstractions, primitives, and operational reliability every time custom requests, complexity, or production bugs show up.
