How to Apply for Managing Scientist- Product

at Sublime Systems

🏢 About Sublime Systems

Sublime Systems is pioneering zero-carbon cement production through electrochemical technology, directly tackling the 8% of global CO2 emissions from traditional cement manufacturing. Their breakthrough approach eliminates fossil fuel use and limestone calcination, positioning them as a climate tech leader with strong commercial backing and partnerships. Working here offers the rare opportunity to scale a transformative material science solution with immediate environmental impact.

About This Role

As Managing Scientist-Product, you'll lead technical development of Sublime's cement formulations, focusing on mineral processing, particle technology, and suspension rheology to optimize performance for commercial adoption. You'll manage multiple R&D workstreams while mentoring scientists and engineers, directly translating lab-scale innovations into scalable products. This role is pivotal for ensuring Sublime's zero-carbon cement meets industry standards while maintaining its environmental advantages.

💡 A Day in the Life

Your day typically involves morning stand-ups with R&D teams to review experimental progress on milling optimization and rheology testing, followed by hands-on lab time designing or analyzing cement property measurements. Afternoons include data interpretation sessions, cross-functional meetings with engineering teams to align on product development priorities, and mentoring junior scientists on experimental design for suspension characterization.
