Design a simple lightweight, robust structure for a solar machine prototype.
We design and build industrial systems to replace fossil fuels.
To join us, you’ll complete a short challenge. Not to test what you know, but to understand how you think, design, and make decisions.
Each challenge takes approximately 6–10 hours. There is no perfect solution, we care about your reasoning, trade-offs, and clarity.
