Our mission is to help marketers succeed by combining marketing technologies and data to create meaningful relationships that generate revenue.

We believe a better workplace creates a better customer experience – we work hard, but also love to learn and have fun.

With a young, dynamic, and collaborative team that is truly international and multicultural, you’ll have the opportunity to grow!

Role Overview

This hybrid position is based in Madrid, offering the perfect balance of collaboration and flexibility.

As a JavaScript Developer at Kapturall, you will design and implement solutions that integrate marketing automation tools with modern technologies.

You will leverage your expertise in JavaScript, Node.js, and serverless architectures to develop and deploy innovative applications, APIs, and workflows that support our clients’ marketing automation goals.

Key Responsibilities

  • Develop and maintain scalable solutions using JavaScript, Node.js, and serverless architectures within Azure.

  • Build, consume, and optimize REST APIs, ensuring seamless integration with third‑party tools.

  • Design, develop and maintain WordPress‑based platforms, themes, and plugins.

  • Collaborate with the team to design, implement, and troubleshoot advanced solutions and systems.

  • Support projects that involve Adobe Marketo and its REST API, creating custom integrations and enhancements.

  • Create frontend applications and scripting for various internal and client sites and platforms.

  • Work closely with clients and internal teams to understand technical requirements and deliver solutions that meet business objectives.

  • Ensure code quality, security and performance optimization across all projects.

Ideal Candidate Profile

  • Proven experience in JavaScript and Node.js development.

  • Advanced English skills are mandatory (interviews will be conducted entirely in English).

  • Proficiency with serverless architectures (e.g., Azure Functions, AWS Lambda, Google Cloud Run).

  • Strong knowledge of REST API development and consumption.

  • PHP skills and, preferably, a background in WordPress development.

  • Proficiency in using Git for version control, including branching, merging, and collaboration workflows.

  • Familiarity with Adobe Marketo and its REST API is a significant plus.

  • Experience working in remote teams and managing projects in a fast‑paced, client‑oriented environment.

  • Ability to solve complex problems and communicate technical solutions effectively.

  • Self‑motivated, with a proactive approach to learning and development.

Perks and Benefits

  • Work with a multi‑cultural and ambitious team full of energy and keen to apply cutting‑edge technology.

  • Competitive salary based on responsibilities and experience, plus a performance‑based bonus.

  • Continuous training covering digital marketing and soft skills.

  • Regular after‑works and fun activities such as escape rooms, wine tasting or simply hanging out with colleagues.

  • Company‑paid language courses to keep growing personally and professionally.

  • Fully covered gym membership.

  • Extra day off for your birthday.

  • Flexible working hours and hybrid working model.

  • New office space with flexible options for in‑person collaboration or remote work.
