Frontend Developer (Web & Mobile)

Were looking for a Frontend Developer to join our team in Copenhagen - someone equally comfortable shipping on the web and on mobile. This is a genuinely 50/50 role split between our web platform and native app work not a web role with occasional mobile work.

Youll split your time across our web platform and the Dreaminfluence app - a mobile platform that thousands of influencers use to discover brand campaigns upload content track performance and get paid. Dreaminfluence 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 1000 customers report close to 9M in ARR and employ over 70 people across offices in Stockholm Barcelona Amsterdam and Copenhagen.

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 this team youll find a balance of challenge creativity and ownership with plenty of opportunities to make a real impact on Flowboxs 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. AI is part of how we work day to day - we build with Claude Code not as an experiment on the side but as a normal part of the toolkit.

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.

As our Frontend Developer in Copenhagen youll contribute across both our web app and the Dreaminfluence mobile app - building new features improving existing workflows and helping raise the bar on user experience across the board.

• This is roughly a 50/50 role: youll split your time between our web front end (Vue 2 migrating to React) and our React Native mobile app - both are core to the job not a primary/secondary split.

• On mobile youll own real feature work in the Dreaminfluence app - the React Native platform thousands of influencers use daily - from building new screens to shipping to the App Store and Play Store.

• On web youll play a part in migrating our apps from Vue 2 to React - a chance to help shape a modern front end not just maintain whats already there.

• Youll integrate with our REST API built in - and because youre comfortable or eager to learn to work with APIs youll sometimes reach into the backend to unblock a feature or track down a bug.

• Youll work closely with product managers designers and other developers to shape solutions improve workflows and deliver a cohesive experience for our users.

• Youll contribute to the design and implementation of new features across the app(s) with an eye for a smooth reliable experience for thousands of users.

• Youll have the chance to contribute to cross-product or cross-team initiatives.

• Experimentation is encouraged and youll have a high degree of ownership over what you build.

Were open on seniority - mid-level to senior - as long as you can ship production front-end code with confidence.

Youll thrive here if you have:

• 3 years building production front-end applications with solid component-framework fundamentals - Vue and/or React - plus strong TypeScript. We run Vue 2 today and are migrating to React in the near future so experience with either (and comfort moving between the two) is valuable.

• Comfort working in a web codebase day to day - component architecture state management testing

• Production React Native experience including 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/or Play Store - youve navigated review rejections and know how to ship around them

• Solid instincts around REST API integration error handling and asynchronous/loading/offline states

Nice to have:

• Comfort jumping into our backend when a feature needs it

• Push notification architecture (OneSignal or similar)

• CI/CD experience with GitHub Actions

• Native iOS or Android experience for the moments Expo cant cover

• Experience with a Vue-to-React migration or standing up a React codebase from scratch

You dont need to tick every box. If youre missing one or two but bring strong fundamentals and curiosity apply anyway.

• Team size: Youll join a Copenhagen team of 3 developers 1 full-stack data scientist 1 designer and a product manager

• Reporting: You will be reporting to our Engineering Team Lead

• Hybrid: Were in the office at least 3 days per week with flexibility around the rest

• Compensation: 482.4k DKK - 723.6k DKK yearly depending on experience plus pension contribution

• Start date: Flexible but ideally 1st of October or before

• Relocation: We can support relocation to Copenhagen for the right candidate including visa sponsorship where applicable

• Tech stack: Vue 2 today with a migration to React in the near future - plus on the backend React Native Expo and TypeScript on mobile GitHub Actions and New Relic for monitoring. We build with Claude Code as part of our day-to-day workflow.

Flowbox offers a fast-moving and at the same time relaxed work environment in modern premises in the heart of Copenhagen.

You will have large responsibilities and great career opportunities. You will work with a wide and modern tech stack; as one of our teammates says: if you work at Flowbox you will be able to work anywhere.
