Front-End Developer - Amsterdam

Job Description

As a Front-End Developer, you will work in a dynamic environment where digital purchase journeys and commercial customer experience are central. As part of the Sales Flow team, you will 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 will also collaborate closely with product, UX, and back-end stakeholders to deliver reliable, scalable, and conversion-focused sales experiences.

You will join a scrum team operating in an active architecture transition, moving 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, while your focus will remain on the core energy purchase journey. This is a dynamic environment where resilience, ownership, and openness to giving and receiving feedback are essential.

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.

• 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.
