About the role
Company overview Lydian is developing the lowest cost sustainable fuels from waste CO₂, water, and renewable electricity to decarbonize the aviation industry. Our breakthrough technology replaces oil and gas refining with fully electrified, modular, and flexible reactor systems that produce fuel with 95% lower emissions than traditional jet fuel. Since our founding in 2021, Lydian has achieved key milestones in record time, including the production of our first liquid fuel from our pilot system. Lydian is backed by the world's top energy transition investors including Congruent Ventures, Galvanize Climate Solutions, Union Square Ventures, Voyager Ventures, Grok Ventures, and Overture. We have also earned support from the US Department of Energy, the Defense Advanced Research Projects Agency (DARPA), and have been recognized by Forbes 30u30 and by Silicon Valley Bank's 50 by 2050 List which recognizes the top fifty energy transition companies based on potential impact and scale. Position Overview Lydian is seeking a Senior Manager, Materials Design & Manufacturing to establish and scale the first production processes and supply chain for the critical materials and components that enable our reactor and module platforms. This role owns the translation of materials R&D into repeatable, production-ready processes, the design of early production lines (internal and external), and the operational systems required to support near-term execution and long-term scale. You will work closely with manufacturing partners and internal engineering teams to ensure materials development remains aligned with core technical programs, mechanical designs, and operating modes. You will build and manage a multidisciplinary team across manufacturing engineering, quality, and materials science, while setting the operational rigor required for FOAK production and beyond. This role is based onsite in Charlestown, MA and requires in-person collaboration five days per week. Key
