Job Description

Lydian overview

Lydian is a technology development company focused on producing the cheapest carbon-neutral fuels and chemicals on the planet. Our process replaces oil and gas refining with fully electrified, modular, and highly efficient reactor systems that enable the upgrading of captured CO2 into a range of carbon-neutral fuels and chemicals. Our initial focus is on the production of the cheapest and most scalable CO2-derived aviation fuel.

Lydian is backed by top climate investors including Congruent Ventures, Galvanize Climate Solutions, Union Square Ventures, Voyager Ventures, Grok Ventures, and Overlap Holdings. We are building a motivated, diverse, and collaborative team that is passionate about addressing the growing climate crisis and is committed to excellence in their work. In particular, we look for tenacious people that are energized by solving the hardest, highest impact problems that come their way.

Position overview

We are seeking a highly motivated and detail-oriented Senior Process Engineer to join our team and contribute to the development and optimization of our sustainable aviation fuel plants. You’ll collaborate with the R&D and engineering teams to define and model our demo/commercial-scale systems and be the key point of contact with our EPC partners to evaluate and provide input on design packages.

Strong candidates will have a degree in Chemical Engineering and several years of experience with chemical process design. The ideal candidate should have a passion for sustainable energy and a desire to work in a fast-paced startup environment.

Core responsibilities

  • Design, develop, and optimize chemical processes with a focus on process safety, operability, and reliability.

  • Develop process flow diagrams, heat and mass balances, and process simulation models using industry-standard software tools (such as Aspen Plus or HYSYS).
