UI / UX designer

At Project Picoballoon, we’re building the next generation of atmospheric monitoring with ultra-light, solar-powered balloons that autonomously travel the globe, gathering real-time weather data at a fraction of the cost of satellites.

Our mission is clear: make high-quality environmental data accessible, affordable, and scalable for researchers, governments, and communities worldwide. By revolutionizing climate monitoring, we’re not just improving weather prediction, we’re providing critical information for climate resilience and disaster prevention.

• Ideate, wireframe, prototype, design, and test intuitive user interfaces for our software hub, including a mission control dashboard, meteorological data visualization tools, and weather balloon management tools.

• Collaborate with our communications department to ensure brand consistency in visual design and storytelling.

• Create comprehensible documentation based on your research and work.

• Collaborate with software engineers and product managers on integrating design into a production-ready product.
