About the solid-state battery catholyte role

• Lead catholyte product development as its technical owner
• Understand transport, interface stability, microstructure and mechanical limits of electrolytes in cathodes
• Use electrochemistry, microscopy and characterisation to link structure to performance
• Develop new characterisation methods
• Manage and mentor scientists, and work with modelling, engineering and manufacturing on scale-up
• Work with customers, write invention disclosures and patents, and lead on lab safety

Why this role matters

Solid-state cells could store more energy and burn less easily than today’s lithium-ion cells. The cathode interface is one of the hardest problems left. This role owns that problem at a company that works with carmakers.

What Solid Power is looking for

• PhD in materials science, chemistry, chemical engineering, electrochemistry or a related field, or a master’s with major relevant industry experience
• A record of leading complex R&D projects
• Strong electrochemistry basics and mastery of methods such as three-electrode tests, impedance, DRT, voltammetry or chrono techniques
• Materials characterisation skills, and a record of mentoring and innovation
• Able to work in the lab with PPE, including a full-face respirator or PAPR

Pay and location

The posting gives a salary range of US$105,000 to US$145,000 a year. It adds bonus and equity eligibility, a 401k match, unlimited paid time off and paid holidays. The job may need access to export-controlled technology, so it can depend on a government licence. A background check is required. The posting says nothing about visa sponsorship. It will stay open until filled.
