Senior Frontend Developer

About the Role :

Join our growing engineering team as a Senior Frontend Developer where you'll drive technical excellence across our web and mobile platforms. This hands-on technical leadership role is perfect for developers who excel at solving complex UI challenges and mentoring teams, without the overhead of formal people management.

You'll own end-to-end delivery of user-facing features, from design collaboration to production deployment. As our frontend technical leader, you'll shape component architecture, establish best practices, and ensure exceptional user experiences across all platforms.

Barter – Redefine how brands grow

Barter is transforming the influencer and creator economy from our bases in the Netherlands and Portugal. We’re the platform where brands and creators connect for authentic, cashless collaborations—think product-for-content, not pay-per-post. With over 10,000 vetted creators and micro-influencers across Europe, Barter makes launching campaigns and generating high-quality UGC effortless, scalable, and cost-effective—no agencies or long-term contracts required.

Today, Barter is the go-to marketplace for brands seeking fresh, real content and for creators eager for genuine partnerships. But we’re just getting started. Our next chapter is all about growth : expanding our creator community, rolling out smarter campaign tools, and launching new features like in-app performance tracking.

With current successes in the Netherlands, Belgium, Luxembourg, Germany, France, and the UK, our international expansion will bring our content revolution to new markets in Europe as well as North and South America.

If you want to help shape the future of influencer marketing and build a platform that puts creativity and authenticity first, Barter is where you belong.
