Job description
We are hiring a Senior Full-Stack Web Developer with strong hands-on coding experience and light team or vendor leadership exposure. This role is responsible for building, launching, and maintaining two core web platforms:
- a new vehicle brand website, and
- the Kngloo digital platform.
This is a builder-first role. You are expected to write production code yourself, take technical ownership, and oversee external developers or agencies when required. This is not a pure management role.
Key Responsibilities
Hands-On Development
- Design, develop, and deploy modern, production-ready web applications
- Build and maintain frontend and backend components
- Write clean, maintainable, and scalable code
- Manage deployments, hosting, and basic DevOps workflows
- Own post-launch maintenance, performance optimization, and bug fixing
Technical Ownership & Coordination
- Own the technical architecture and overall codebase
- Make pragmatic technology and stack decisions
- Review and approve code from external contractors or agencies
- Coordinate with third-party developers when additional capacity is required
- Maintain documentation, coding standards, and best practices
Collaboration
- Work closely with internal stakeholders to translate business requirements into technical execution
- Provide technical guidance when working with designers, vendors, or contractors
Requirements
Do you have experience in React?, Must-Have
- 6+ years of professional web development experience
- Strong hands-on experience as a Full-Stack Web Developer
- Proven experience building and launching websites end-to-end
- Experience owning projects with minimal supervision
- Some exposure to leading or coordinating developers (internal or external)
- Solid working proficiency in English (spoken and written)
- Ability to work on-site in Sant Boi de Llobregat, Barcelona
Technical Skills (stack flexible)
- Modern frontend frameworks (React, Vue, or similar)
- Backend development (Node.js, Python, PHP, or equivalent)
- APIs, databases, authentication, and integrations
- CMS or headless CMS experience
- Deployment, hosting, and basic infrastructure management
Nice to Have
- Experience with e-commerce or digital platforms
- Exposure to payment systems or third-party integrations
- Startup or scale-up experience
