at Vizzuality

🏢 About Vizzuality

Vizzuality is a mission-driven tech company that builds tools to address climate change, biodiversity loss, and inequality. They combine cutting-edge data visualization with a strong commitment to social and environmental impact, making them a unique place for engineers who want their code to contribute to global conservation.

About This Role

As a Software Engineer at Vizzuality, you will develop and maintain web applications that visualize nature-related and sustainability data, such as tracking deforestation or mapping species habitats. Your work will make complex biodiversity information accessible and beautiful, directly contributing to global conservation efforts.

💡 A Day in the Life

Your day might start with a standup to discuss progress on a feature like a species habitat map. You'll then write code for a new data layer, review a colleague's pull request, and test your changes. After lunch, you might pair with a designer to refine a visualization's interactivity, then end the day by deploying a small update to production.
