This position is ideal for someone junior or mid-level who is quick to learn and eager to deliver value across projects.
What You'll Work On
We have:
* 15+ active clients — including publishers, eCommerce brands, and performance agencies, with diverse yet increasingly standardized infrastructures.
You will work on:
* AI-driven tools: embedding GPT-4 and other services into internal and client-facing apps
* Multi-MTA dashboards: enhancing our Virtual Deliverability Manager for SparkPost, qMail, and Amazon SES
* Mautic plugin development: automating campaigns and improving UX for marketing teams
* Web apps & UIs: building lightweight tools and landing pages using modern frameworks

* Mautic
* WhatsApp & Codex
You understand the value of:
* Frugality and working with efficient, lean architectures
You can communicate effectively in informal conversations (not necessarily fluent, but clear)
You care about products, UX, and outcomes, not just code
You are independent, organized, and good at managing your time and priorities
Comfortable with variety and navigating imperfect setups, sometimes figuring out the way forward
Interested in meaningful AI applications, not just buzzwords, and willing to build or find an efficient, diverse team of AI agents to collaborate with us
Why Work With Us
* Hybrid role: just 1 day/week in our Barcelona office
* Clients include Brown-Forman and Moonshot Marketing
* Influence tool evolution with real product input
