## Description

Inscribirse en esta oferta Blue Code Alicante is hiring a Senior FullStack Integration Engineer to join one of our clients, an international SaaS company building product configuration and personalization technology for e-commerce and enterprise customers. You will take ownership of customer integrations from development through delivery. The role is explicitly expected to own integration outcomes rather than only complete assigned development tickets (approximately 70% hands-on technical work and 30% coordination and communication), working closely with Project Managers, developers and other specialists.

Responsibilities

 + Build and maintain customer integrations, mainly through custom development and APIs
 + Take technical ownership of integrations from requirements through testing and delivery
 + Investigate and solve integration issues across different customer platforms
 + Maintain a clear overview of status, dependencies, risks and next steps
 + Work closely with Project Managers and communicate technical risks or missing information early
 + Support Sales and PMs with technical requirements during discovery and pre-sales
 + Work with platforms such as Make.com and customer systems including Magento, Shopify and WooCommerce when required
 + Proactively follow up on blockers instead of waiting for tasks or reminders
