* 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 InfoJobs & Hireflix). Global 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: https://www.Elmundo.Es/economia/empresas/2026/05/31/6a19bfc9fdddff06268b4570.Html
* 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.
Requirements
* 3+ years as Tech Lead, Principal Engineer, Head of Engineering, or technical owner at CTO level.
* Experience building product for real enterprise clients.
* Experience with production, reliability, integrations, security, or compliance.
* Advanced use of AI agents, LLMs, and AI-native workflows in software development.
* Massive agentic coding skills: claude code/codex expert.
* Product sensibility: flows, edge cases, error states, and acceptance criteria.
* Obsession with production quality.
* Ability to lead technically while remaining deeply hands-on.
* You've had to live with the consequences of your own technical decisions in real systems.
Nice to Have
* Experience in AI, LLMs, agents, HR tech, recruiting, or workflow automation.
* Having taken an MVP to an enterprise platform.
* Agentic-maxxing mindset: using AI agents as real leverage for one person or a small team, not as a gimmick.
Personal Traits & Working Style
* Deeply technical profile, obsessed with infrastructure, architecture, and product.
* Someone who sees custom requests and thinks abstractions; who sees bugs and thinks feedback loops; who sees complexity andthinks primitives.
* Not a Jira manager — someone who builds the system and works with AI agents as second nature.
Salary & Location
* €60k–€100k + Equity, depending on experience and seniority.
* BCN vs Remote: We prefer engineers who can work onsite in Barcelona (our 6-person team is currently 100% based onsite in the city), but we prioritize talent and are open to 100% fully remote positions.
