Lyten

Develops lithium-sulfur batteries and 3D graphene-based materials to enable higher-performance, more sustainable energy storage and advanced composites.

Product Design Engineer

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.

We're seeking a Product Design Engineer with deep experience in pouch cell design, productization, and manufacturing scale-up to lead the mechanical design and integration of next-generation pouch battery systems. This role will own cell architecture, engineering drawings, and BOM strategy from concept through pilot and production. The ideal candidate will bring strong technical leadership, cross-functional influence, and hands-on battery design expertise to deliver robust, scalable, and high-performance products.

Job Responsibilities:

  • Lead design and release of pouch cell assembly drawings, specifications, CAD models, and BOMs
  • Own electrode layout, stack architecture, and mechanical containment design
  • Drive design-for-manufacturability and scale-up readiness
  • Lead DFMEA/PFMEA, tolerance stack-up, and engineering change management
  • Resolve complex assembly and integration challenges (tabs, sealing, electrolyte distribution, swelling)
  • Translate manufacturability into robust design rules
  • Lead DOE planning and statistical analysis to optimize performance
  • Establish in-process quality control and inspection criteria
  • Drive root-cause analysis and corrective actions
  • Collaborate cross-functionally with manufacturing, quality, and supply chain
  • Support supplier technical reviews and cost reduction initiatives
  • Mentor junior engineers and provide technical leadership

Required Skills/Qualifications:

  • MSc in Mechanical Engineering, Chemical Engineering, Materials Science, or related field
  • 3+ years hands on experience in cell design working in the high volume battery manufacturing industry
  • Proficient in CAD design (SolidWorks preferred)
  • Experience with PLM/PDM systems
  • Proficient in data analysis tools (Python, R, MATLAB, Excel)
  • Understanding of battery quality control methods (Hi-Pot, dimensional analysis, CT scans, weld testing, leak testing, etc.)
  • Knowledge of statistical process control (SPC)
  • Strong understanding of pouch cell architecture, cell electrochemistry and battery performance trade-offs
  • Experience working with cross-functional NPI or pilot builds in a fast-paced environment.

Physical Requirements:

  • Must be able to lift 50 lbs.
  • Be able to work in a lab standing up to 8 hours each day.

Compensations Range:

The expected base salary range for this position is between $128,200.00 - $192,400.00. The level of pay within the range will depend on a variety of job-related factors that may include location, relevant prior experience and/or education, or particular skills and expertise.
