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.
