Mobile developer - Copenhagen

We're looking for a motivated Mobile Developer to join our team in Copenhagen. Flowbox was founded in 2016 and is a fast-growing tech scale-up with large ambitions and broad visions. We provide a SaaS platform that helps brands improve their marketing, social media and e-commerce strategies. Our technology helps our clients to better collect, manage, and distribute their own customers' content, aka user generated content (UGC).

Earlier this year, Flowbox acquired the Danish company Dreaminfluence, a leading influencer marketing platform. Post-acquisition, Flowbox now serves more than 1,000 customers, reports close to €9M in ARR, and employs over 70 people across offices in Stockholm, Barcelona, Amsterdam, and Copenhagen.

Tech Stack

We work with a modern, component-driven frontend stack designed for performance, scalability, and great developer experience:

• Languages & Frameworks: React Native, Expo, Storybook, TypeScript

• Infrastructure & Cloud: GitHub Actions for CI/CD, OneSignal

• Architecture & Monitoring: Component-driven architecture, NewRelic

About the team

Our Tech Department is made up of two core teams:

• 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.

• 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.

Your mission

As a Mobile Developer at Flowbox, you’ll take ownership of our influencer app built in React Native, driving its development, performance, and user experience end-to-end.

• 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 will work with technologies such as React Native, Expo, TypeScript, and GitHub.

As part of the team, you’ll participate in team ceremonies such as Sprint Planning, Daily Scrum, Product Reviews, and Sprint Retrospectives, contributing your ideas and insights on functionality, architecture, methods, and processes.

About you

To thrive in this role, you should have experience with mobile or full-stack development. You have strong coding skills in TypeScript and are comfortable working with React Native and Expo to build and maintain production-ready apps.

Experience with REST APIs, GitHub workflows, and modern CI/CD practices is a plus.

It’s an advantage if you’ve worked in a fast-paced, agile environment with a startup mindset where ownership, adaptability, and curiosity matter. You bring an entrepreneurial approach, a strong sense of responsibility, and a genuine interest in learning and improving your craft.

At Flowbox, we value openness, collaboration, and clear communication. We give and receive feedback, support each other, and constantly aim to build better products together.

Why join Flowbox?

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”. We want to accomplish our goals, but we need your help to do so.

More about our perks:
