front end developer angular

For this role, we work with a tailored CV and a short self assessment to ensure alignment before interviews are scheduled. About KPN & the QCarbon / Kult Team Within KPN we are building and operating world class networks (No.1 globally in 5G) and continuously digitalising our processes. A key part of this is developing secure, reliable and scalable internal platforms that support critical business operations. The QCarbon / Kult team develops and maintains a suite of security applications that support Business Continuity Management and Penetration Test Management. These applications are business critical and used across the organisation. We are a DevOps product team consisting of:

• 4 experienced, knowledge driven engineers
• 1 product owner
• 1 scrum master The team is international, based in Rotterdam (The Netherlands), and works in a hybrid setup. We collaborate closely with stakeholders from Security, Infrastructure, AWS and the business. Stakeholders actively join refinement sessions and sprint moments and visit the team weekly at the office. Currently, we are rebuilding the backend from Django / Django REST Framework / Redis to FastAPI and SQLAlchemy, running in Docker on AWS. This modernisation is expected to be finalised in summer ’26 and will enable new functional and technical features. The frontend plays a key role in effectively consuming these APIs and ensuring a consistent, secure and high quality user experience.
