The Front-End Developer is responsible for the design and implementation of the User interface. The Front-End Developer defines the web page design and structure; Develops features to enhance the users' experience; Finds a balance between functional and aesthetic design; Makes the web design is smartphone-capable; Builds reusable code for future use; Secures web pages are optimized for best speed and scalability; Employs a diverse selection of markup languages to design web pages; Keeps the brand consist throughout the whole design.


In this role, you will work in a dynamic environment where digital purchase journeys and commercial customer experience are central. As a Front-end Developer in the Sales Flow team, you take ownership of the Commodity purchase flow - the journey where customers configure and sign up for energy products on Vattenfall.nl and related channels. You collaborate closely with product, UX, and back-end stakeholders to deliver reliable, scalable, and conversion-focused sales experiences.


The team operates in an active architecture transition: from declarative flow configuration toward a central orchestrator model, with Commodity being extracted into its own feature library. Sustainability flows (solar, heat pump, insulation) are integrated but owned elsewhere; your focus stays on the core energy purchase journey. It is a dynamic environment where we need someone who is resilient under pressure, takes responsibility, and is willing to both give and receive feedback.


As part of a dedicated scrum team, your responsibilities include:


•

• Developing, maintaining, and optimizing the Commodity purchase flow in Angular, including product configuration, multi-step forms, and order submission.


• Building and supporting: a standalone Angular application and CMS-embedded Angular web components for EPiServer pages.


• Integrating with back-end services for product selection, offers, leads, address lookup, usage estimation, and order APIs.


• Support our data-driven CXO experiments for improving in the sales funnel. Coordinate and develop new A/B tests with our experimentation tool in VWO using feature flags.


• Write unit tests and collaborate with our QA colleague in building new Cypress E2E regression tests; contributing to CI/CD pipelines and releases across dev, tst, acc, and prd.


• Participating in several AI initiatives with our core AI / Nina team


• Contributing to front-end standards and best practices within the Nx monorepo, including design system adoption and Tailwind migration.


• Collaborating with UX, platform, and back-end teams on API contracts, performance, accessibility, and production support.


• Challenging requirements and translating them into technically feasible, maintainable solutions.




Hard skills:


•

• Proven experience (Minumum 5 years) with Angular (v20+), TypeScript, SCSS, HTML5, and RxJS/Signals.


• Experience or interest in developing code with AI tools.


• Experience with state management (NGXS or similar) and REST/BFF integration patterns.


• Experience with unit testing (Jest/Vitest) and E2E testing (Cypress).


• Familiarity with web components (@angular/elements), and lazy-loaded routing.


• Experience with CI/CD (Azure DevOps), Nx monorepos, and trunk-based Git workflows.


• Understanding of Azure Cloud and REST-based architectures.


• Experience with analytics tagging (Relay, Adobe) and A/B testing tools (e.g., VWO) is a plus.




Soft skills:


•

• Customer-focused mindset with strong communication skills and the ability to collaborate effectively with non-technical stakeholders.


• Structured and proactive way of working, with a passion for quality, continuous improvement, and reliable delivery in production-critical flows.




Education:


Bachelor's or Master's degree in Computer Science, Engineering, or a related technical field.


Practical information:


•

• Previous experience in the energy sector is not required.


• Fluent in Dutch (mandatory) and English, both written and spoken.
