Are you a roll-to-roll machinery innovator who dreams of designing the manufacturing lines that will revolutionize solar tech? Do you excel at turning complex equipment challenges into elegant hardware solutions? Join Rayleigh Solar Tech as the Director of Equipment Engineering, where you'll drive the design and deployment of the advanced production tools needed to scale our next-generation perovskite solar modules.

At Rayleigh, we're building the lowest-cost source of clean electrons on the planet. Backed by world-class investors and a powerhouse technical team, we're pushing the limits of deep tech to make solar radically more accessible. Our culture thrives on curiosity, urgency, and the pursuit of excellence - and we're looking for someone who shares that fire.

In this role, you'll lead the effort to architect our roll-to-roll production line from the ground up. From selecting and procuring high-tech coating and printing systems to overseeing their installation and commissioning, you'll ensure our factory of the future becomes reality. You'll collaborate across teams to tailor equipment for our unique process needs and leverage your expertise to troubleshoot and optimize every machine. Your work will lay the physical foundation that turns laboratory breakthroughs into scalable products.

If you're a hands-on engineering leader with deep technical chops, a passion for large-scale automation, and the vision to build a first-of-its-kind solar manufacturing line, we want to work with you.
