Lyten is leading an industrial revolution through Lyten 3D Graphene™, 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. Job Scope   High level purpose of function. The primary purpose of this role is to develop, characterize, and   optimize   advanced welding processes, specifically Laser Welding and Ultrasonic Welding, to ensure high-quality, high-volume production.

This engineer acts as the subject matter expert (SME) for process capability, yield improvement, and defect reduction in critical joining applications, particularly for thin metals, plastics, or dissimilar materials (e.g., in battery components or electronic assemblies). Key Responsibilities   Key responsibilities include (but are not limited to)   Process Development & Qualification:   Design and execute Design of Experiments (DOE) methodologies to define and optimize critical welding parameters (e.g., laser power, welding speed, focal distance, pulse duration, ultrasonic pressure/amplitude) for new products and materials.

Develop and qualify Welding Procedure Specifications (WPS) and process control plans for both Laser and   Ultrasonic welding   in accordance with   industry codes (e.g.,   AWS, ASME)   Optimization & Improvement:   Apply Statistical Process Control   (SPC)   and   Lean   Manufacturing principles   (FMEA)   to   monitor   process performance, reduce variability, and drive continuous improvement in yield, throughput, and cost.

Lead Root Cause Analysis   (RCA)   and implement corrective actions for welding defects such as   porosity, cracking,   tears, cold welds,   spatter, and material deformation. Design for Manufacturability   (DFM)   Collaborate with Product Design /R & D   teams to ensure new product designs are   optimized   for manufacturability   using   specialized   welding technologies (e.g., recommending   optimal   joint configuration and material   fit up ).

Equipment & Tooling:   Define specifications for and   participate   in the   selection , installation, and commissioning of new Laser and Ultrasonic welding equipment and custom tooling/fixtures. Knowledgeable in CE and regulatory requirements. Work with equipment and manufacturing to define and document the process set up   and parameters. Training & Documentation:   Create detailed   Bill of Process (BOP) ,   work instructions   standard operating procedures   ( SOP)     and   training programs for welding technicians and operators to ensure process adherence and safety.

Accountability/Authorization   Budget responsibility:   No   Direct reports:   No   Manager work environment responsibility:   No   All employees are accountable for   complying with   safety regulations and actively supporting a safe workplace. Decision Authority: Authorized to recommend temporary process halts when weld quality or safety is compromised. Can define and update process parameters within the qualified   WPS   range.
