How to Apply for Senior Frontend Designer

at Lunar Energy

🏢 About Lunar Energy

Lunar Energy is at the forefront of the green tech revolution, combining AI with solar and battery systems to make homes more sustainable. Their mission-driven approach and focus on cutting-edge technology make them a compelling place for designers who want to have a real impact on climate change.

About This Role

As a Senior Frontend Designer, you'll bridge design and engineering, owning the component library that powers Lunar's AI-driven energy interfaces. Your work will directly influence how users interact with sustainable energy systems, ensuring a seamless and intuitive experience across devices.

💡 A Day in the Life

You might start your day with a standup with the design system team, then dive into Figma to prototype a new interactive chart for the energy dashboard. After lunch, you could pair with a frontend engineer to implement a complex date picker, ensuring it meets both design specs and performance benchmarks. Later, you'll review PRs from other teams using the component library and provide feedback to maintain consistency.

Include a link to your live component library or a case study showing how you improved consistency and developer efficiency.

4

Mention any experience with motion design or animation, as this is listed in the requirements and sets you apart.

5

Write a short cover letter that connects your work to sustainability—show you understand Lunar's mission and how your skills can advance it.
