Your Mission

We are looking for the next amazing addition to our Product team! We are looking for a motivated and enthusiastic Product Designer to help with our cross-functional teams.

As a our second designer in a Product team, you will play a crucial role in defining, prioritizing, and delivering quality experiences that align with our overall mission of build Europe’s leading energy management platform to provide fair, clean energy to everyone.

These can include work on our innovative dynamic tariffs, smart devices integration and usage statistics, or our ongoing growth and retention projects.

What you will be keeping busy with

• Design Ownership: Own the end-to-end design process for our mobile app and website. Work with Product Managers to research problems, conduct user interviews, and gather data. Create prototypes to test ideas, deliver designs ready for engineering, and measure success after launch.

• Customer Advocacy: Be in touch with customers and use design expertise to become an internal expert and advocate on how they think, what is a good user experience for them, and how we should reflect that in our product.

• Design Processes: Maintain and improve ongoing design processes, and artifacts such as design system, tooling, and collaboration methods.

• Collaboration: Work closely with our Senior Product Designer, Product Managers, the tech team, and other stakeholders to define requirements, facilitate workshops, iterate on solutions, and deliver designs that align with business & customer goals, and that balance design quality and timely delivery.

Your Profile

• Strong visual design skills, with understanding of how colors, typography, and spacing work.

• Understanding of mobile design principles, such as Human Interface Guidelines and Material Design.

• Knowing how to do user research and usability testing, with strong instincts on what makes a good user experience to delight customers.

• Stakeholder management skills, including communication, alignment, and gathering and integrating feedback — we like to promote a culture of transparency.
