Lyten is leading an industrial revolution through Lyten 3D GrapheneTM, a breakthrough supermaterial unlocking a new generation of products — from lithium–sulfur batteries and energy storage systems to concrete admixtures, lightweight composites, and next-generation sensors that are revolutionizing industries. Together, these innovations are making a massive global improvement and driving real-world impact across energy, mobility, construction, and defense.

At Lyten, we believe the most meaningful careers begin with purpose — and with people who want to make a difference. We’re not just developing advanced supermaterials — we’re about to change the world as we know it, reshaping how energy is stored, how products are built, and how progress is made.

We’re entering an exciting growth phase, scaling production across the U.S. and Europe and expanding our team of engineers, scientists, and innovators.

Apply now to join our team and be part of something bigger than yourself — where collaboration, creativity, and purpose come together to build the technologies that will define the next century.
** Senior Composites Engineer
**** Position Overview
** We are seeking a highly driven Senior Composites Engineer to lead the development of Carbon Fiber Reinforced Polymer (CFRP) formulations integrating Lyten’s proprietary materials. In this role, you will be the technical anchor for integrating our advanced nanomaterials into resin systems tailored for high-performance composite applications.

You will work cross-functionally, serving as the critical bridge between the internal materials synthesis team, product engineering teams, and the end-product manufacturing teams (both internal and external partners). Your primary objective will be to formulate, scale, and deliver manufacturable resin systems for use in prepreg, resin transfer molding (RTM), or similar composite manufacturing formats.
*
* Please note:

** This is a heavily applied, commercial product development role. We are seeking candidates with a proven track record of bringing materials from the lab into scaled manufacturing, rather than purely academic or fundamental research experience.
** Key Responsibilities**
* ** Formulation & Development:**  + Design and formulate polymer matrix systems (e.g., epoxies, thermoplastics, or advanced thermosets) incorporating Lyten 3D GrapheneTM to enhance mechanical, thermal, and electrical properties in CFRPs.  + Optimize resin rheology, tack, out-life, and cure kinetics specifically for prepreg manufacturing and automated layup processes.
* ** Cross-Functional Integration:**  + Create and communicate project documentation and share timelines and results in the form of presentations with internal teams  + Collaborate closely with the internal materials team to dial in nanomaterial functionalization and dispersion techniques.  + Partner with product teams to define material specifications based on end-user mechanical and environmental requirements.  + Work hand-in-hand with end-product manufacturing teams to ensure formulations are drop-in compatible with existing prepreg, towpreg, or liquid molding production lines.
* Ability to travel periodically to other facilities, customer visits and trade shows
* ** Process Scale-Up & Validation:**  + Transition material formulations from bench-top R&D to pilot scale, and ultimately into high-volume commercial manufacturing.  + Develop and execute design of experiments (DoE) to optimize formulation processing parameters.
* ** Characterization & Testing:**  + Oversee thermal, rheological, and mechanical testing (e.g., DMA, DSC, TGA, Rheometry,…
