Job Title: Full Stack Engineer (AI Tools, Martech & Product-Building)
Location: 100% Remote – with occasional meetups in Barcelona for lunch, beers, and product deep dives
(We like in-person time when it matters.)
Type: Full-Time
At Data Innovation, we help marketing and CRM teams work smarter with automation, analytics, and AI. Our mission: simplify complex Martech stacks and build lightweight tools that actually solve problems.
We're looking for a versatile Full Stack Engineer - a builder who’s curious, autonomous, and eager to grow into someone who can think like both a developer and a product manager. This role is perfect for someone junior or mid-level who’s not afraid to explore, learn quickly, and deliver real value across projects.
What You'll Work On
We have 15+ active clients - from publishers to eCommerce brands to performance agencies - with slightly different infrastructures, now increasingly standardized. You’ll 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 : building features to automate campaigns and improve UX for marketing teams
* Web apps & UIs : building lightweight tools and landing pages using modern frameworks
* API integrations : connecting CRM, marketing automation, and analytics platforms
* Client-specific solutions : helping us propose, spec, and implement solutions for companies like Nestlé, Tradedoubler, Brown-Forman and Moonshot Marketing.
What We’re Looking For
* You can code full stack: Python (FastAPI), JavaScript, HTML/CSS, React or Vue/Angular
* You’re familiar with (or eager to learn): SQL, Airflow, Amazon Athena, Docker, YAML, Amazon Web Services, Mautic, WhatsApp & Codex.
* You understand the value of frugality and working with efficient, lean architectures
* You can speak decent English in non-formal conversations (you don’t need to be fluent—just clear)
* You care about products, not just code: you enjoy understanding users and thinking about UX and outcomes
* You’re independent and organized, capable of managing your time and priorities
* You’re comfortable with variety and navigating imperfect setups—sometimes you’ll need to figure out the way forward
* You’re interested in how AI can be used meaningfully, not just as a buzzword and willing to find or build an efficient and diverse team of AI Agents to collaborate with us .
Why Work With Us
* Hybrid role: just 1 day/week at our Barcelona office
* Clients you’ll grow with: including Nestlé, Tradedoubler, Brown-Forman and Moonshot Marketing.
* Real product input: you’ll help shape how tools evolve, not just build features
*
