To further increase our impact on mental healthcare, we are looking for a senior fullstack engineer who brings a critical eye, versatility and frontend expertise to our ambition. In this key role, you are the link between our strong foundation and the user-friendly, client-focused features that drive our core metric; Monthly Helped Users. With your broad skillset, you don’t just build beautiful interfaces — you also think along about the architecture behind them.

Accelerate our client-focused roadmap by deploying your frontend expertise, while simultaneously supporting the team with backend expertise. You ensure we can build the features that lift our platform from a solid foundation to a user-friendly, internationally scalable application.

About Therapieland

At Therapieland, we believe quality mental healthcare should be within everyone's reach — anytime, anywhere. That's why we're committed to making psychological support accessible and approachable.

Our e-health platform brings together online programs, video consultations, and questionnaires in one seamless experience. As market leaders across primary care, mental health services, the social domain, and hospital care, we never stop innovating. Every day, we help thousands of people build mental resilience and take charge of their wellbeing.

What will you do as a senior fullstack engineer?

In this role, you are responsible for developing client-focused features for our e-health platform. You work primarily on the frontend (70%) with Vue.js, while stepping in on the backend with Python/Django (30%) when needed, allowing you to deliver features end-to-end with minimal dependencies.

Your main responsibilities:

• Feature development: You build new functionalities such as notifications, program localization, improved login/registration flows, and dashboard optimizations that directly contribute to our mission: 100 million helped people.

• Frontend architecture: You proactively think along about the evolution of our frontend architecture and ensure scalability and maintainability

• Full-stack capabilities: You develop RESTful APIs in Django when backend support is needed, so you don't have to wait for colleagues' availability

• Code quality & security: You ensure high security standards in both frontend and backend code through code reviews, security best practices, and WCAG compliance

• Collaboration: You work closely with UX/UI designers, Product Owners, and your engineering colleagues to translate technical requirements into functional solutions

• AI-augmented development: You use AI tools, systems, and workflows to increase your productivity, spend more time on problem-solving and less on execution

Projects you'll work on: You’ll focus on app.therapieland.nl - our main platform that helps thousands of people daily with their mental health. The foundation is solid; you build the features that take the platform to the next level for international expansion.

A typical day: Your day starts with updating Asana and participating in the daily stand-up. Then you work on sprint tickets - this could mean building a Vue component for a new notification feature, developing a Django API endpoint, or pair-programming with a colleague on a complex user flow. In between, you have alignment sessions with the Product Owner and UX/UI about technical feasibility and implementation details.
