Role Description This full-time Vibe Engineer — Full-Stack / Backend Developer role at IAG Services is based in Barcelona in a hybrid setup, combining on-site collaboration with flexible work-from-home days. The role focuses on designing, building, and maintaining scalable backend services and full-stack features that support internal tools, client-facing products, and the overall "vibe" and user experience of IAG platforms. Day-to-day responsibilities include implementing clean, testable code, integrating APIs, optimizing performance, and collaborating closely with product, design, and data teams to translate requirements into robust technical solutions.

This role also involves monitoring production systems, troubleshooting issues, and suggesting improvements to both the codebase and the collaborative culture of the team. We are recruiting a Vibe Engineer to join the IAG technology team and help one of our flagship accounts ship operational software at a pace traditional development can't match. You'll be embedded in Vibe Team , a deliberately small delivery team on our client account, building a new production application every month for a BPO/CX client — QA scorecards, workforce management tools, client reporting, escalation tracking — with AI-native development on a governed enterprise app platform (think Lovable, with enterprise-grade RBAC, SSO, audit and environments built in).

Your craft is everything around it — framing the problem precisely, driving the agent well, and applying real engineering judgment to what comes back. IAG is at the forefront of the AI revolution in the Telecommunication and CX space — driving innovation in ML, cloud computing and software engineering across customer services,



telecommunications, big data and automation.

This role sits on our BPO/CX client account: one of the world's leading customer experience companies, 170,000 people supporting 750+ of the world's best-known brands. The IAG technology team is a very collaborative and dynamic work environment. We build new products and services around collaboration with our customers, team ideas and audacity.

You will work in a two-person pod with a Tech Lead, with real ownership of a whole application — not a sliver of one. Frame & Prototype (Week 1): Turn an operational problem into a working clickable prototype with AI generation, put it in front of vigente end users, and help make the honest call to continue, pivot or kill. Build & Harden (Weeks 2–3): Wire real data through governed connectors, write tests, close out the security checklist, and iterate with the AI on what matters — data models, backend logic, integrations (REST APIs, SQL, SSO via Keycloak). you are the judgment on top of it.

Solid full-stack or backend fundamentals: you can design a sane data model, reason about an API, debug a query and read a stack trace. Fluency with AI-assisted development (Claude, Cursor, Copilot, Lovable or similar), with real opinions about when the output is good and when it's confidently wrong.

Nice to have: internal-tooling platforms (Superblocks, Retool, Power Platform), CI/CD and Git-based review workflows, BPO/CX exposure, French or Spanish on top of fluent English. Work on projects with real-world impact, leveraging cutting-edge technologies. A front-row seat on the future of the craft: the industry is moving from writing code to orchestrating it — practiced daily here with guardrails, not chaos.
