About us

We're an independent European digital product studio with a strong track record of delivering market-defining strategies and products for enterprises and governments. With about 200 talented people across three countries, premium AI capabilities and a diverse portfolio of international clients, we define, design and ship high-quality digital products, strategies and software. From global cloud-based platforms and large-scale apps to medical devices, banking software and augmented reality experiences. In a nutshell: if it lives and breathes digital, it’s what we do best.

Become a part of our team

At In The Pocket, you join a multidisciplinary team of designers, engineers, strategists and data specialists who care about the work as much as the people they work with. We work in small, autonomous teams that stay close to our clients and their users, and we give everyone the space to take ownership, speak up and grow. You’ll learn from colleagues across our studios, ship products that reach thousands or even millions of people and help shape what digital can do for leading organisations in Europe.

  • Solid grasp of common software engineering practices: OO principles, modern design patterns, test-driven development, continuous integration and continuous deployment. 
  • Good understanding of security concepts and best practices (OWASP).
  • Good understanding of DevOps practices (infrastructure as code (terraform), observability, CI/CD)
  • Excellent problem-solving and debugging skills.
  • Strong communication and collaboration skills.
  • A passion for building high-quality, maintainable, scalable, and secure software.
  • You apply AI tools at an advanced level to accelerate high-quality delivery, and you critically validate what comes out of them (e.g., Claude, Codex, etc).
  • Nice to have:
    • Quarkus 
    • GraalVM

  • Our benefits package has you covered with medical insurance, meal vouchers, and more.
  • You’ll have a mobility budget that lets you decide how to get around, your way.
