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.
What you’ll do
- 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.
Who you are
- 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 Dutch and English.
What we offer
Joining In The Pocket means becoming part of a team that shapes the future of our clients’ businesses across Europe. Here’s what you can look forward to:
- You’ll start with a permanent contract in a role that comes with responsibility and the opportunity to make a real impact from day one.
- We offer a competitive salary that reflects your experience and the value you bring.
- Our benefits package has you covered with hospitalisation and group insurance, meal vouchers, a phone subscription, and more.
- You’ll have a mobility budget that lets you decide how to get around, your way.
- Life at In The Pocket isn’t just about work, we host team events throughout the year to celebrate, connect, and have fun together.

- Define and enforce best-practices for Windows desktop development across the codebase: code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability.
- Drive accessibility efforts: integrate and validate support for accessibility APIs (e.g. Microsoft UI Automation or other relevant Windows accessibility frameworks), ensure UI controls, focus management, keyboard navigation, screen-reader support, and usability for users with disabilities.
- Collaborate closely with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and long-term roadmap for the Windows platform.

Required:
- 3+ in Windows desktop application development using Windows App SDK, WinUI (or similar), C#, XAML — and ideally additional experience with native Windows code (C++, Win32/WinRT/COM).
- Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code.

- Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
- Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
- A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users.
Preferred / Bonus:
- Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.
- Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).
- Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.
- Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.
- Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications.
- Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management.

Your work will directly contribute to delivering on critical customer commitments and will help inform future product development. This role is ideal for an individual contributor who thrives in dynamic environments and enjoys taking ownership of complex technical problems from design to delivery.
This is a full-time, remote position based in the Netherlands or Belgium with up to 50% time onsite with the customer. If located near the office, you are expected to work from that office 3 days per week.
Impact You’ll Own:
- Contribute to the full development lifecycle: from discovery and decomposition to designing, building, and deploying bespoke solutions for customer challenges.
- Design and develop robust, full-stack software, including front-end, back-end, data integration, cloud infrastructure (e.g., AWS), and CI/CD pipelines.
- Work directly with customers to understand their operational challenges and translate them into clear technical requirements.
- Identify reusable patterns in customer solutions to inform broader platform development.
- Leverage the latest AI tooling and an AI-first mindset to drive rapid iteration, deliver value quickly, and adapt to evolving requirements with a bias for action.
- Mentor other engineers, contribute to code reviews, and help foster a collaborative team environment.
- Deliver critical commitments on time, understanding their direct impact on customer relationships and business objectives.
What You Bring:
- 6+ years of relevant work experience in software engineering or in an equivalent technical role.
- Bachelor’s Degree in a relevant field.
- Experience with geospatial software development and concepts (e.g., Rasterio, Fiona, Shapely, OpenLayers, GDAL).
- AWS or GCP experience.
- Proficiency in Python.
- Excellent knowledge of software engineering best practices, including coding standards, code reviews, source control management, and testing methodologies.
- Excellent customer engagement skills, with the ability to communicate complex technical concepts to diverse audiences.
- Experience with fast, iterative development cycles and an ability to adapt to shifting requirements.
- Willingness to travel 30-50% to customer sites within the region.
- Have the ability to obtain and maintain a security clearance.
What Makes You Stand Out:
- Experience with JavaScript, Java, Go or C#
