At Phlair, we’re on a mission to reverse climate change with Direct Air Capture (DAC) technology. Our scalable, cost-efficient electrochemical DAC system removes CO2 from the atmosphere, storing it permanently or converting it into CO2-negative chemicals. We’ve developed a breakthrough hydrolizer for acid/base regeneration, and we’re working with forward-thinking customers like Frontier Climate, Stripe, Shopify, and Klarna.
As a Working Student in Mechatronics & Control Engineering, you’ll play a critical role in developing and optimizing systems that power our DAC technology at scale. You’ll work alongside our Control and Data Engineer, Xun, to implement, improve, and maintain the core software and systems that enable our innovative technology.
