Senior C# Back-End Engineer

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.

• As a part of the team, you’ll be taking part in the continuous development of the products that are in the care of your team.
• Day to day, this means developing new user stories, fixing bugs, creating & reviewing pull requests, documenting your work (code comments, readme, confluence,..), performing research, making suggestions for product improvements and communicating clearly about your progress.
• Together with your colleagues, you’ll be making sure the product meets all functional and non-functional requirements.
• As an engineer, you understand that producing clean, readable, and testable code is always a priority.
• Use AI tools (e.g., Copilot, ChatGPT) in your development workflow to enhance code writing, support code reviews, and improve productivity.

• Strong knowledge of C# and .NET 6+ (8+ years of experience).
• Good working knowledge of Docker.
• Familiarity with at least one cloud platform (Azure, Google Cloud Platform, or Amazon Web Services).
• Use AI tools (Copilot, ChatGPT, Cursor and others) to support your daily development work and improve code quality.
• Exposure to database technologies such as Redis, MongoDB, or InfluxDB.
• Some experience with messaging and broker systems (Pub/Sub, RabbitMQ, Kafka).
• Familiarity with Terraform, Go, or Elastic Search is a plus.
• You hold a master or bachelor degree in Computer Science/Informatics (or equal through a proven track record).
• You have a good understanding of common software engineering practices, like OOP principles, modern design patterns, test-driven development, continuous integration and continuous deployment.
• You value clean code and clean architecture principles, and strive to produce clean, readable and testable code.
• You’re eager to learn new things, share your knowledge, adapt to change and learn from past experiences.
• You’re able to work effectively in a team and are always open to feedback from your teammates.
• You understand the importance of application security and data security, and know how that affects your job.
• You communicate fluently in English and Dutch or French.
