Descripción completa del empleo

We're looking for a motivated Backend Developer to join our UGC Platform Team in Barcelona.

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, cloud-native stack built for scalability and performance:

Languages & Frameworks: Python (Flask, FastAPI), Celery
Databases & Storage: PostgreSQL, DynamoDB, Amazon S3
Infrastructure & Cloud: AWS (Lambda, CloudWatch, Kinesis, Athena, EKS), Docker, Kubernetes
Architecture & Tooling: Microservices, Event-driven systems, GitHub Actions for CI/CD, 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 UGC Platform Backend Developer at Flowbox, you’ll play a vital role in shaping the core infrastructure that powers our product, a platform used by hundreds of leading brands around the world.

You’ll be part of an autonomous, cross-functional, agile team that designs, builds, and maintains backend services that are highly available, low-latency, and scalable. Your work will directly impact how we collect, process, and deliver user-generated content at scale.

In this role, you will:

Design and develop robust APIs, microservices, and backend systems that power our UGC platform.
Collaborate closely with engineers, product managers, and designers to bring new features to life and improve existing functionality.
Investigate and resolve production issues across multiple services, ensuring reliability, scalability, and performance.
Contribute to architectural decisions, infrastructure improvements, and process enhancements to help our platform grow efficiently.
Work with a modern tech stack including Python, Docker, AWS (S3, Athena, Lambdas), Kubernetes, PostgreSQL, and DynamoDB.
Participate actively in Sprint Planning, Daily Standups, Product Reviews, and Retrospectives, continuously improving how we build, deliver, and learn together.

About you

You’re a backend developer with 3-4+ years of hands-on experience building reliable, scalable systems. You have strong, practical experience with Python, and you take pride in writing clean, maintainable code that powers products millions of users rely on every day.

You’re comfortable working with Celery, Flask, Docker, PostgreSQL, and Kubernetes, and you understand how to design and maintain microservice architectures. You have hands-on experience with AWS services like CloudWatch, Kinesis, EKS, Lambdas and DynamoDB, and you’re confident in navigating modern cloud environments.

You thrive in collaborative, open environments where ideas are shared freely and feedback is valued. You’re curious about how systems perform in production and motivated by delivering solutions that create real business value. Above all, you’re passionate about continuous learning, improving your craft, and contributing to great products that make a difference.

Why join Flowbox?

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

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:

A startup spirit with the stability of a growing international company
Hybrid work model (3+2), enjoy a flexible balance with three days in the office and two days working from home
Modern, central offices with free snacks and drinks
Half-days before holidays, more time to enjoy life outside work
Health and wellbeing benefits, including Gympass/Wellhub and private health insurance
Cobee for flexible benefit management
Fun afterworks and company events across our teams
The freedom to work from any of our four locations, Barcelona, Copenhagen, Amsterdam, or Stockholm
Amazing teammates to learn from, collaborate with, and have fun alongside across four countries

Apply today! We can't wait to meet you!
