Senior React Native Developer

We're looking for a React Native developer to join our team in Copenhagen.

You'll be working on the Dreaminfluence app — a mobile platform that thousands of influencers use to discover brand campaigns, upload content, track performance, and get paid. The app is the influencer-facing side of a two-sided marketplace: brands run campaigns on our web platform, and influencers find and deliver them through the app.

Dreaminfluence was acquired by Flowbox earlier this year. Flowbox is a SaaS company founded in 2016 that helps brands collect, manage, and distribute user-generated content. Post-acquisition, we serve more than 1,000 customers, report close to €9M in ARR, and employ over 70 people across offices in Stockholm, Barcelona, Amsterdam, and Copenhagen.

About the team

Our Tech Department is made up of two core teams:

• The Influencer Platform Team (Copenhagen):

The team behind the influencer marketing part of the Flowbox platform, developing and maintaining a platform for influencer collaboration, campaign management, and performance tracking. We handle everything from influencer payments and reporting to analytics and insights, making it simple for brands and influencers to connect, collaborate, and generate results.

We work cross-functionally in a hybrid environment, collaborating across disciplines to deliver impactful solutions. In this team, you’ll find a balance of challenge, creativity, and ownership, with plenty of opportunities to make a real impact on Flowbox’s core product.

We believe in pair programming, regular code reviews, and open feedback, helping each other grow while maintaining high-quality standards across everything we build.

• The UGC Platform Team (Barcelona):

Responsible for the heart of our UGC platform, including integrations, back-office tools, content collection, moderation, and distribution. We also manage event streams, analytics, and data infrastructure, ensuring our systems are efficient, reliable, and scalable

Your mission

As our Mobile Developer in Copenhagen, you'll own the Dreaminfluence influencer app end-to-end — the React Native app that thousands of influencers use daily to discover campaigns, upload content, track performance, and get paid.

• You will contribute to the design and implementation of new features and improvements across the app, ensuring a smooth and reliable experience for thousands of users.
• You will play a key role in developing new features and improving the app experience for thousands of users.
• You will collaborate across the full stack, from design and UI to integrating with our REST API built in Node.js, and have a real impact on how our product evolves.
• You will work closely with product managers, designers, and other developers to shape solutions, improve workflows, and deliver a cohesive user experience.

You'll work with React Native, Expo, TypeScript, Storybook, GitHub Actions, and NewRelic for monitoring.

About you

We're open on seniority — mid-level to senior — as long as you can ship production React Native code with confidence.

You'll thrive here if you have:

• 3+ years building production mobile apps, with meaningful React Native and TypeScript experience
• Comfort with the Expo workflow (EAS Build, OTA updates, config plugins when you need to escape the managed flow)
• A track record of shipping to the App Store and Play Store — you've navigated review rejections and know how to ship around them
• Solid instincts around REST API integration, error handling, and offline states

Nice to have:

• Native iOS or Android experience for the moments Expo can't cover
• Experience working across the full stack — comfortable jumping into the Node.js backend when a feature needs it
• Push notification architecture (OneSignal or similar)
• CI/CD with GitHub Actions

You don't need to tick every box. If you're missing one or two but bring strong fundamentals and curiosity, apply anyway.
