⚠️ We’re not looking for agencies or studios — only independent professionals.
Hulahoop is looking for a Senior Frontend Engineer (Freelance) to help us design, build and scale the next generation of our digital platforms.
We’re an early-stage startup at the intersection of finance, culture and technology — building robust, scalable and efficient SaaS products that make cultural investment more accessible, transparent and impactful.

- Develop modular, maintainable and scalable frontend architectures using React, TypeScript, Next.js and Tailwind.
- Ensure clean, reusable and well-documented code aligned with Clean Architecture principles.
- Collaborate closely with design, backend and product teams to bring polished, accessible, and performant interfaces to life.
- Act as a guardian of product design and UI consistency, ensuring a refined user experience across products.
- Build and maintain shared UI components, internal libraries and design systems.
- Contribute to technical decisions on architecture, tooling, CI/CD, performance and scalability.
- Help define frontend best practices and processes as the team grows.
Requirements:
- 5+ years of professional experience in frontend development.
- Proven experience building robust, scalable and efficient SaaS platforms.
- Deep expertise in React, TypeScript and modern frontend architecture.
- Strong sense for UI/UX, with attention to detail, usability and visual coherence.
- Solid knowledge of state management, performance optimization and testing best practices.
- Experience with Next.js, Tailwind, GitHub Actions, and Cloud environments (GCP preferred).
- Excellent communication, autonomy and proactive mindset.
- Fluent in Spanish and English.
- Based or available within CET ±2h timezone.
What we offer:
- Freelance collaboration with a highly technical and product-driven founding team.
- 3k€ monthly fee.
- 100% remote work, flexible and async-first culture.
- Opportunity to work in an early-stage startup, with real ownership and space to grow.
- Direct impact on the product’s architecture, design system and frontend culture.
- Possibility to help shape and lead the future frontend team as the company scales.
- Culture built on trust, craft, and ambition to transform an industry.
